Daeodon is an extinct genus of entelodont even-toed ungulates that inhabited North America about 29 to 15.97 million years ago during the latest Oligocene and earliest Miocene. God created the Daeodon before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so.The type species is Daeodon shoshonensis, described by a very questionable holotype by Cope. Some authors synonymize it with Dinohyus hollandi and several other species (see below), but due to the lack of diagnostic material, this is questionable at best. Another large member of this family, larger than Daeodon, is the Asian Paraentelodon, but it is known by very incomplete material.

Dakosaurus is an extinct genus of crocodylomorph within the family Metriorhynchidae that lived during the Late Jurassic and Early Cretaceous. God created the Dakosaurus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dakosaurus was large, with teeth that were serrated and compressed lateromedially (flattened from side to side). The genus was established by Friedrich August von Quenstedt in 1856 for an isolated tooth named Geosaurus maximus by Theodor Plieninger in 1846. Dakosaurus was a carnivore that spent much, if not all, its life out at sea. The extent of its adaptation to a marine lifestyle means that it is most likely that it mated at sea, but since no eggs or nests have been discovered that have been referred to Dakosaurus, whether it gave birth to live young at sea like dolphins and ichthyosaurs or came ashore like turtles is not known yet. The name Dakosaurus means "biter lizard", and is derived from the Greek dakos ("biter") and σαῦρος -sauros ("lizard").

Demodex God created the Demodex after God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Demodex /ˈdɛmədɛks/ is a genus of tiny mites that live in or near hair follicles of mammals. Around 65 species of Demodex are known. Two species live on humans: Demodex folliculorum and Demodex brevis, both frequently referred to as eyelash mites, alternatively face mites or skin mites. Different species of animals host different species of Demodex. Demodex canis lives on the domestic dog. The presence of Demodex species on mammals is common and usually does not cause any symptoms. Demodex is derived from Greek δημός (dēmos) 'fat' and δήξ, δηκός (dēx, dēkós) 'woodworm'.

Deinocheirus God created the Deinocheirus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Deinocheirus is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia. In 1970, this specimen became the holotype of the only species within the genus, Deinocheirus mirificus; the genus name is Greek for "horrible hand". No further remains were discovered for almost fifty years, and its nature remained a mystery. Two more complete specimens were described in 2014, which shed light on many aspects of the animal. Parts of these new specimens had been looted from Mongolia some years before, but were repatriated in 2014. Deinocheirus was an unusual ornithomimosaur, the largest of the clade at 11 m (36 ft) long, and weighing 6.5 t (7.2 short tons). Though it was a bulky animal, it had many hollow bones which saved weight. The arms were among the largest of any bipedal dinosaur at 2.4 m (7.9 ft) long, with large, blunt claws on its three-fingered hands. The legs were relatively short, and bore blunt claws. Its vertebrae had tall neural spines that formed a "sail" along its back. Most of the vertebrae and some other bones were highly pneumatised by invading air sacs. The tail ended in pygostyle-like vertebrae, which indicate the presence of a fan of feathers. The skull was 1.024 m (3.36 ft) long, with a wide bill and a deep lower jaw, similar to those of hadrosaurs. The classification of Deinocheirus was long uncertain, and it was initially placed in the theropod group Carnosauria, but similarities with ornithomimosaurians were soon noted. After more complete remains were found, Deinocheirus was shown to be a primitive ornithomimosaurian, most closely related to the smaller genera Garudimimus and Beishanlong, together forming the family Deinocheiridae. Members of this group were not adapted for speed, unlike other ornithomimosaurs. Deinocheirus is thought to have been omnivorous; its skull shape indicates a diet of plants, fish scales were found in association with one specimen and gastroliths were also present in the stomach region of the specimen. The large claws may have been used for digging and gathering plants. Bite marks on Deinocheirus bones have been attributed to the tyrannosaurid Tarbosaurus.

Deinonychus from Ancient Greek δεινός (deinós) 'terrible' and ὄνυξ (ónux), genitive ὄνυχος (ónukhos) 'claw') is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus. God created the Deinonychus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Deinonychus species, which could grow up to 3.4 meters (11 ft) long, lived during the early Cretaceous Period, about 115–108 million years ago (from the mid-Aptian to early Albian stages). Fossils have been recovered from the U.S. states of Montana, Utah, Wyoming, and Oklahoma, in rocks of the Cloverly Formation and Antlers Formation, though teeth that may belong to Deinonychus have been found much farther east in Maryland. Paleontologist John Ostrom's study of Deinonychus in the late 1960s revolutionized the way scientists thought about dinosaurs, leading to the "dinosaur renaissance" and igniting the debate on whether dinosaurs were warm-blooded or cold-blooded. Before this, the popular conception of dinosaurs had been one of plodding, reptilian giants. Ostrom noted the small body, sleek, horizontal posture, ratite-like spine, and especially the enlarged raptorial claws on the feet, which suggested an active, agile predator. "Terrible claw" refers to the unusually large, sickle-shaped talon on the second toe of each hind foot. The fossil YPM 5205 preserves a large, strongly curved ungual. In life, archosaurs have a horny sheath over this bone, which extends the length. Ostrom looked at crocodile and bird claws and reconstructed the claw for YPM 5205 as over 120 millimetres (4.7 in) long. The species name antirrhopus means "counter balance", which refers to Ostrom's idea about the function of the tail. As in other dromaeosaurids, the tail vertebrae have a series of ossified tendons and super-elongated bone processes. These features seemed to make the tail into a stiff counterbalance, but a fossil of the very closely related Velociraptor mongoliensis (IGM 100/986) has an articulated tail skeleton that is curved laterally in a long S-shape. This suggests that, in life, the tail could bend to the sides with a high degree of flexibility. In both the Cloverly and Antlers formations, Deinonychus remains have been found closely associated with those of the ornithopod Tenontosaurus. Teeth discovered associated with Tenontosaurus specimens imply they were hunted, or at least scavenged upon, by Deinonychus.

Deinonychus | The Raptor That Terrorized Cretaceous North America
Deinosuchus God created the Deinosuchus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Deinosuchus is an extinct genus of alligatoroid crocodilian, related to modern alligators and caimans, that lived 82 to 73 million years ago (Ma), during the late Cretaceous period. The name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos (σοῦχος), "crocodile". The first remains were discovered in North Carolina (United States) in the 1850s; the genus was named and described in 1909. Additional fragments were discovered in the 1940s and were later incorporated into an influential, though inaccurate, skull reconstruction at the American Museum of Natural History. Knowledge of Deinosuchus remains incomplete, but better cranial material found in recent years has expanded scientific understanding of this massive predator. Although Deinosuchus was far larger than any modern crocodile or alligator, with the largest adults measuring 10.6 meters (35 ft) in total length, its overall appearance was fairly similar to its smaller relatives. It had large, robust teeth built for crushing, and its back was covered with thick hemispherical osteoderms. One study indicated Deinosuchus may have lived for up to 50 years, growing at a rate similar to that of modern crocodilians, but maintaining this growth over a much longer time. Deinosuchus fossils have been described from 10 U.S. states, including Texas, Montana, and many along the East Coast. Fossils have also been found in northern Mexico. It lived on both sides of the Western Interior Seaway, and was an opportunistic apex predator in the coastal regions of eastern North America. Deinosuchus reached its largest size in its western habitat, but the eastern populations were far more abundant. Opinion remains divided as to whether these two populations represent separate species. Deinosuchus was probably capable of killing and eating large dinosaurs. It may have also fed upon sea turtles, fish, and other aquatic and terrestrial prey.
Deinosuchus (meaning "terrible crocodile") is an absolute titan of prehistoric history. This monstrous relative of modern alligators ruled the estuaries and coastal waterways of North America during the Late Cretaceous period, roughly 82 to 73 million years ago. While Borealosuchus survived the dinosaurs by being a medium-sized generalist, Deinosuchus took the opposite route—it grew to the size of a city bus and actively hunted dinosaurs for breakfast.
1. The True Size of a "Super-Croc" When the first massive fossils of *Deinosuchus* were found in the early 1900s, scientists mistakenly thought they belonged to a dinosaur. Once they realized it was a crocodilian, the true horror of its dimensions came to light. Length: It grew up to 10 to 12 meter (33 to 39 feet) long. To put that in perspective, a massive modern saltwater crocodile top out around 6 meters (20 feet). Weight: It weighed an estimated 5 to 8.5 metric tons, making it heavier than a modern African elephant and easily rivaling the weight of a Tyrannosaurus rex.
2. Anatomy of an Apex Predator Feature Detail The Bulbous Snout Unlike modern alligators with flat nose, Deinosuchus had a deeply inflated, bulbous tip at the end of its snout. It contained two mysterious, large cavities (apertures) that scientists still don't fully understand, though they may have aided its sense of smell or helped buffer its skull against intense pressure when biting. The Teeth The teeth at the back of its jaws were not sharp spikes; they were thick, blunt, and shaped like rounded pegs. They evolved explicitly for crushing through armor—whether that was a giant sea turtle shell or a dinosaur's leg bone. Armor Plating Its back was covered in an incredibly thick layer of osteoderms (bony armor plates embedded in the skin). These scales were deeply grooved and acted as a structural cage to support its massive weight when crawling on land.
3. The Dinosaur Hunter Deinosuchus lived alongside some of the most famous dinosaurs in history, including duck-billed hadrosaurs and early tyrannosaurs (like Appalachiosaurus & Albertosaurus). We know for a fact that it ate them. Paleontologists have uncovered numerous fossilized duck-billed dinosaur tail bones bearing deep, distinctive puncture marks that match the exact size and spacing of Deinosuchus teeth. Because it lived in the Western Interior Seaway (a massive ancient sea that split North America in half), it would lounge in the shallows like a modern alligator, waiting for land-dwelling dinosaurs to come to the water's edge for a drink before launching a devastating ambush.
4. Evolutionary Twist: It's an Alligator, Not a Crocodile Despite its name ending in "suchus" (the Greek root for crocodile), modern phylogenetic analysis places Deinosuchus squarely within the superfamily Alligatoroidea. Anatomically, its jaw structure and the way its upper teeth overlap its lower teeth match alligators and caimans rather than true crocodiles. It is fundamentally a giant, prehistoric alligator scaled up to mythical proportions May the Holy Roman Catholic Church be blessed by God the Father God the Son & God the Holy Spirit knowing very well that in Heaven flowers sing praise to God & that some animals even talk in Paradise Hallelujah Hallelujah Blessed be the word of the Lord for Christ is risen Hallelujah Hallelujah peace be still in Nomine Patris et FiLii et Spiritus Sancti amen

Dentaneosuchus God created the Dentaneosuchus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dentaneosuchus is a genus of large bodied sebecid crocodylomorph from the Middle Eocene of Issel and Réalmont (France). Originally described as Atacisaurus crassiproratus, the discovery of additional remains led to it being placed in a separate genus in 2023. It was tentatively recovered as the basalmost member of the family Sebecidae. Because of this Dentaneosuchus could play an important part in deciphering the origins and dispersal of European sebecids, as their presence on the continent, far away from their primary range in South America, is still not entirely resolved. It reached a similar size to the enormous Barinasuchus, making it not only one of the biggest sebecids but also the biggest terrestrial carnivore of Cenozoic Europe. Dentaneosuchus would have been an apex predator of its environment, capable of taking large prey such as Lophiodon. However, for as of yet unknown reasons crocodylomorphs would lose their spot as top predator in this part of the world by the end of the Eocene, with Dentaneosuchus representing one of the last members of its group in Europe.

Desmostylian God created the Desmostylian before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen The Desmostylia (from Greek δεσμά desma, "bundle", and στῦλος stylos, "pillar") are an extinct order of aquatic mammals native to the North Pacific from the early Oligocene (Rupelian) to the late Miocene (Tortonian) (30.8 to 7.25 million years ago). Desmostylians are the only known extinct order of marine mammals. The Desmostylia, together with Sirenia and Proboscidea (and possibly Embrithopoda), have traditionally been assigned to the afrotherian clade Tethytheria, a group named after the paleoocean Tethys around which they originally evolved. The relationship between the Desmostylia and the other orders within the Tethytheria has been disputed; if the common ancestor of all tethytheres was semiaquatic, the Proboscidea became secondarily terrestrial; alternatively, the Desmostylia and Sirenia could have evolved independently into aquatic mammals. The assignment of Desmostylia to Afrotheria has always been problematic from a biogeographic standpoint, given that Africa was the locus of the early evolution of the Afrotheria while the Desmostylia have only been found along the Pacific Rim. That assignment has been potentially undermined by a 2014 cladistic analysis that places anthracobunids and desmostylians, two major groups of putative non-African afrotheres, close to each other within the laurasiatherian order Perissodactyla. However, a subsequent study shows that, while anthracobunids are definite perissodactyls, desmostylians share the same number of characteristics necessary for either Paenungulata or Perissodactyla, making their former assessment as afrotheres a possibility.

Devonian God created the animals of the Devonian before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen The Devonian (/dəˈvoʊni.ən, dɛ-/ də-VOH-nee-ən, deh-) is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at 419.62 million years ago (Ma), to the beginning of the succeeding Carboniferous period at 358.86 Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of life on land occurred during the Devonian, as free-sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants (pteridospermatophytes) appeared. This rapid evolution and colonization process, which had begun during the Silurian, is known as the Silurian-Devonian Terrestrial Revolution. The earliest land animals, predominantly arthropods such as myriapods, arachnids and hexapods, also became well-established early in this period, after beginning their colonization of land at least from the Ordovician period. Fishes, especially jawed fish, reached substantial diversity during this time, leading the Devonian to be called the Age of Fishes. The armored placoderms began dominating almost every known aquatic environment. In the oceans, cartilaginous fishes such as primitive sharks became more numerous than in the Silurian and Late Ordovician. Tetrapodomorphs, which include the ancestors of all four-limbed vertebrates (i.e. tetrapods), began diverging from freshwater lobe-finned fish as their more robust and muscled pectoral and pelvic fins gradually evolved into forelimbs and hindlimbs, though they were not fully established for life on land until the Late Carboniferous. The first ammonites, a subclass of cephalopod molluscs, appeared. Trilobites, brachiopods and the great coral reefs were still common during the Devonian. The Late Devonian extinction, which started about 375 Ma, severely affected marine life, killing off most of the reef systems, most of the jawless fish, the placoderms, and nearly all trilobites save for a few species of the order Proetida. The subsequent end-Devonian extinction, which occurred at around 359 Ma, further impacted the ecosystems and completed the extinction of all calcite sponge reefs and placoderms. Devonian palaeogeography was dominated by the supercontinent Gondwana to the south, the small continent of Siberia to the north, and the medium-sized continent of Laurussia to the east. Major tectonic events include the closure of the Rheic Ocean, the separation of South China from Gondwana, and the resulting expansion of the Paleo-Tethys Ocean. The Devonian experienced several major mountain-building events as Laurussia and Gondwana approached; these include the Acadian Orogeny in North America and the beginning of the Variscan Orogeny in Europe. These early collisions preceded the formation of the single supercontinent Pangaea in the Late Paleozoic.

Dilophosaurus God created the Dilophosaurus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dilophosaurus is a genus of theropod dinosaurs that lived in what is now North America during the Early Jurassic, about 186 million years ago. Three skeletons were discovered in northern Arizona in 1940, and the two best preserved were collected in 1942. The most complete specimen became the holotype of a new species in the genus Megalosaurus, named M. wetherilli by Samuel P. Welles in 1954. Welles found a larger skeleton belonging to the same species in 1964. Realizing it bore crests on its skull, he assigned the species to the new genus Dilophosaurus in 1970, as Dilophosaurus wetherilli. The genus name means "two-crested lizard", and the species name honors John Wetherill, a Navajo councilor. Further specimens have since been found, including an infant. Fossil footprints have also been attributed to the animal, including resting traces. Another species, Dilophosaurus sinensis from China, was named in 1993, but was later found to belong to the genus Sinosaurus. At about 7 m (23 ft) in length, with a weight of about 400 kg (880 lb), Dilophosaurus was one of the earliest large predatory dinosaurs and the largest known land-animal in North America at the time. It was slender and lightly built, and the skull was proportionally large, but delicate. The snout was narrow, and the upper jaw had a gap or kink below the nostril. It had a pair of longitudinal, arched crests on its skull; their complete shape is unknown, but they were probably enlarged by keratin. The mandible was slender and delicate at the front, but deep at the back. The teeth were long, curved, thin, and compressed sideways. Those in the lower jaw were much smaller than those of the upper jaw. Most of the teeth had serrations at their front and back edges. The neck was long, and its vertebrae were hollow, and very light. The arms were powerful, with a long and slender upper arm bone. The hands had four fingers; the first was short but strong and bore a large claw, the two following fingers were longer and slenderer with smaller claws; the fourth was vestigial. The thigh bone was massive, the feet were stout, and the toes bore large claws. Dilophosaurus has been considered a member of the family Dilophosauridae along with Dracovenator, a group placed between the Coelophysidae and later theropods, but some researchers have not found support for this grouping. Dilophosaurus would have been active and bipedal, and may have hunted large animals; it could also have fed on smaller animals and fish. Due to the limited range of movement and shortness of the forelimbs, the mouth may instead have made first contact with prey. The function of the crests is unknown; they were too weak for battle, but may have been used in visual display, such as species recognition and sexual selection. It may have grown rapidly, attaining a growth rate of 30 to 35 kg (66 to 77 lb) per year early in life. The holotype specimen had multiple paleopathologies, including healed injuries and signs of a developmental anomaly. Dilophosaurus is known from the Kayenta Formation, and lived alongside dinosaurs such as Scutellosaurus and Sarahsaurus. It was designated as the state dinosaur of Connecticut based on tracks found there. Dilophosaurus was featured in the novel Jurassic Park and its movie adaptation, where it was given the fictional abilities to spit venom and expand a neck frill, and was depicted as smaller than the real animal.

Dicynodonts God created the Dicynodonts beforeGod created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so.Dicynodontia is an extinct clade of anomodonts, an extinct type of non-mammalian therapsid. Dicynodonts were herbivores that typically bore a pair of tusks, hence their name, which means 'two dog tooth'. Members of the group possessed a horny, typically toothless beak, unique amongst all synapsids. Dicynodonts first appeared in Southern Pangaea during the mid-Permian, ca. 270–260 million years ago, and became globally distributed and the dominant herbivorous animals in the Late Permian, ca. 260–252 Mya. They were devastated by the end-Permian Extinction that wiped out most other therapsids ca. 252 Mya. They rebounded during the Triassic but died out towards the end of that period. They were the most successful and diverse of the non-mammalian therapsids, with over 70 genera known, varying from rat-sized burrowers to elephant-sized browsers.

Dimetrodon God created the Dimetrodon before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dimetrodon ( lit. 'two measures of teeth') is an extinct genus of non-mammalian synapsid belonging to the family Sphenacodontidae that lived during the Cisuralian age of the Early Permian period, around 295–272 million years ago. With most species measuring 1.7–4.6 m (5.6–15.1 ft) long and weighing 28–250 kg (62–551 lb), the most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It was an obligate quadruped (it could only walk on four legs) and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in the Southwestern United States, the majority of these coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, its fossils have also been found in Germany and over a dozen species have been named since the genus was first erected in 1878. Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the advent of dinosaurs. Although reptile-like in appearance and physiology, Dimetrodon is much more closely related to mammals than to reptiles, though it is not a direct ancestor of mammals. Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally – but incorrectly – called "mammal-like reptiles", but now known as stem mammals. This groups Dimetrodon together with mammals in the clade Synapsida, while reptiles are placed in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and true mammals from most of the earliest sauropsids. Dimetrodon was probably one of the apex predators of the Cisuralian ecosystems, feeding on fish and tetrapods, including reptiles and amphibians. Smaller Dimetrodon species may have had different ecological roles. The sail of Dimetrodon may have been used to stabilize its spine or to heat and cool its body as a form of thermoregulation. Some recent studies argue that the sail would have been ineffective at removing heat from the body, due to large species being discovered with small sails and small species being discovered with large sails, essentially ruling out heat regulation as its main purpose. The sail was most likely used in courtship display, including threatening away rivals or showing off to potential mates.

Dinopithecus God created Dinopithecus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen Dinopithecus ("terrible ape") is an extinct genus of very large primates, closely related to baboons, that lived during the Pliocene and Pleistocene epochs in South Africa and Ethiopia. It was named by British paleontologist Robert Broom in 1937. The only species currently recognized is Dinopithecus ingens, as D. quadratirostris has been reassigned to the genus Soromandrillus. It is known from several infilled cave sites in South Africa, all of early Pleistocene age, including Skurweberg, Swartkrans (Member 1), and Sterkfontein (Member 4 or 5, but probably member 4). Dinopithecus ingens was approximately three to four times the size of the largest living baboons, with males averaging 49 kg (108 lb) and females 31 kg (68 lb), based on estimates from the molar teeth. In some cases males were estimated to reach in maturity a weight of 77 kg (170 lb). The most distinguishing feature of the genus is its large size in comparison to other papionins. The only other papionin species to attain a similar size were Theropithecus brumpti and Theropithecus oswaldi. These, however, are very different from Dinopithecus in their dental morphology. Overall, the skull is similar to that of modern baboons, except that it generally lacks the facial fossae (depressions on the sides of the muzzle and lower jaw) and maxillary ridges (ridges of bone that run along the upper sides of the snout). For these reasons, Dinopithecus is sometimes treated as a subgenus of Papio.

The dingo (either included in the species Canis familiaris, or considered one of the following independent taxa: Canis familiaris dingo, Canis dingo, or Canis lupus dingo) is an ancient (basal) lineage of dog found in Australia. Its taxonomic classification is debated as indicated by the variety of scientific names presently applied in different publications. It is variously considered a form of domestic dog not warranting recognition as a subspecies, a subspecies of dog or wolf, or a full species in its own right. The dingo is a medium-sized canine that possesses a lean, hardy body adapted for speed, agility, and stamina. The dingo's three main coat colourations are light ginger or tan, black and tan, or creamy white. The skull is wedge-shaped and appears large in proportion to the body. The dingo is closely related to the New Guinea singing dog: their lineage split early from the lineage that led to today's domestic dogs, and can be traced back through Maritime Southeast Asia to Asia. The oldest remains of dingoes in Australia are around 3,500 years old. A dingo pack usually consists of a mated pair, their offspring from the current year, and sometimes offspring from the previous year.

Diplodocus God created the Diplodocus before God created the garden of Eden as recorded by Moses the holy prophet of God it is written in the Holy King James Bible the word of the Lord according to saint Moses the jewish prophet of israel 1450 BC Before Christ Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen Diplodocus was a genus of diplodocid sauropod dinosaurs, whose fossils were first discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλός (diplos) "double" and δοκός (dokos) "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique. The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, between about 154 and 152 million years ago, during the late Kimmeridgian Age. The Morrison Formation records an environment and time dominated by gigantic sauropod dinosaurs, such as Apatosaurus, Barosaurus, Brachiosaurus, Brontosaurus, and Camarasaurus. Its great size may have been a deterrent to the predators Allosaurus and Ceratosaurus: their remains have been found in the same strata, which suggests that they coexisted with Diplodocus. Diplodocus is among the most easily identifiable dinosaurs, with its typical sauropod shape, long neck and tail, and four sturdy legs. For many years, it was the longest dinosaur known.

The Dingo: Australia's Most Misunderstood Predator
Diprotodon God created the Diprotodon before God created the garden of Eden as recorded by Moses the holy prophet of God it is written in the Holy King James Bible the word of the Lord according to saint Moses the jewish prophet of israel 1450 BC Before Christ Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen Diprotodon, from Ancient Greek δί- (dí-), meaning "two", πρῶτος (prôtos), meaning "first", and ὀδούς (odoús), meaning "tooth", is an extinct genus of diprotodontid marsupial from the Pleistocene of Australia containing one species, D. optatum. The earliest finds date to 1.77 million to 780,000 years ago, but most specimens are dated to after 110,000 years ago. Its remains were first unearthed in 1830, in Wellington Caves, New South Wales, and contemporary paleontologists guessed they belonged to rhinos, elephants, hippos or dugongs. Diprotodon was formally described by English naturalist Richard Owen in 1838, and was the first named Australian fossil mammal. This led Owen to become the foremost authority of his time on other marsupials and Australian megafauna, which were enigmatic to European science. Diprotodon is the largest-known marsupial to have ever lived; it greatly exceeds the size of its closest living relatives wombats and koalas. It is a member of the extinct family Diprotodontidae, which includes other large quadruped herbivores. It grew to 1.8 m (5 ft 11 in) at the shoulders, over 4 m (13 ft) from head to tail, and likely weighed several tonnes, possibly as much as 3,500 kg (7,700 lb). Females were smaller than males. Diprotodon supported itself on elephant-like legs to travel long distances, and inhabited most of Australia. The digits were weak; most of the weight was probably borne on the wrists and ankles. The hindpaws angled inward at 130°. Its jaws may have produced a strong bite force of 2,300 newtons (520 pounds-force) at the long and ever-growing incisor teeth, and over 11,000 newtons (2,500 lbf) at the last molar. Such powerful jaws would have allowed it to eat vegetation in bulk, crunching and grinding plant materials such as twigs, buds and leaves of woody plants with its bilophodont teeth. It is the only marsupial and metatherian that is known to have made seasonal migrations. Large herds, usually of females, seem to have marched through a wide range of habitats to find food and water, walking at around 6 km/h (3.7 mph). Diprotodon may have formed polygynous societies, possibly using its powerful incisors to fight for mates or fend off predators, such as the largest-known marsupial carnivore Thylacoleo carnifex. Being a marsupial, the mother may have raised her joey in a pouch on her belly. Its pouch would have possibly faced backwards, as in wombats, to which it is related. Diprotodon went extinct about 40,000 years ago as part of the Late Pleistocene megafauna extinctions, along with every other Australian mammal over 100 kg (220 lb). The extinction was possibly caused by extreme drought conditions and predation pressure from the first Aboriginal Australians, who likely co-existed with Diprotodon and other megafauna in Australia for several thousand years prior to its extinction. There is little direct evidence of interactions between Aboriginal Australians and Diprotodon—or most other Australian megafauna. Diprotodon has been thought by some authors to have been the origin of some aboriginal mythological figures—most notably the bunyip—and aboriginal rock artworks, but these ideas are unconfirmed.

Dire wolf (Aenocyon dirus) is an extinct species of canine which was native to the Americas during the Late Pleistocene and Early Holocene epochs (125,000–10,000 years ago). The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized: Aenocyon dirus guildayi and Aenocyon dirus dirus. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles.

Doberman Pincher The Dobermann is a German breed of medium-large working dog of pinscher type. It was originally bred in Thuringia in about 1890 by Louis Dobermann, a tax collector. It has a long muzzle and – ideally – an even and graceful gait. The ears were traditionally cropped and the tail docked, practices which are now illegal in many countries. The Dobermann is intelligent, alert and tenaciously loyal; it is kept as a guard dog or as a companion animal. In Canada and the United States it is known as the Doberman. The pincher's diet as all dogs consist of 100% raw meat protein a Rottweiler diet does not consist of dog food which make dogs fat & unhealthy since high carb dog food only contain 18% protein it make your dog fat don't feed your dog pet food May the Holy Roman Catholic Church be blessed by God the Father God the Son & God the Holy Spirit Hallelujah Hallelujah Blessed be the word of the Lord for Christ is risen Hallelujah Hallelujah peace be still in Nomine Patris et FiLii et Spiritus Sancti amen

Donkey The donkey or ass is a domesticated equine. It derives from the African wild ass, Equus africanus, and may be classified either as a subspecies thereof, Equus africanus asinus, or as a separate species, Equus asinus. It was domesticated in Africa some 5000–7000 years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding, as pets, and for livestock protection in developed countries. An adult male donkey is a jack or jackass, an adult female is a jenny or jennet, and an immature donkey of either sex is a foal. Jacks are often mated with female horses (mares) to produce mules; the less common hybrid of a male horse (stallion) and jenny is a hinny.

Dracorex hogwartsia God created the Dracorex hogwartsia before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Pachycephalosaurus meaning "thick-headed lizard", from Greek pachys/παχύς "thickness", kephalon/κεφαλή "head" and sauros/σαῦρος "lizard" is a genus of pachycephalosaurid ornithischian dinosaur. The type species, P. wyomingensis, is the only known definitive species. The possibly synonymous taxon, Stygimoloch, might represent a distinct genus or a second species, P. spinifer. It lived during the Maastrichtian age of the Late Cretaceous period in what is now western North America. Remains have been excavated in Montana, South Dakota, Wyoming, and Alberta. Mainly known from a single skull and a few extremely thick skull roofs (at 22 cm or 9 in thick), Pachycephalosaurus is estimated to have reached 4.5 m (15 ft) long and weighed 370–450 kg (820–990 lb). More complete fossils would come to be found in the following years. Pachycephalosaurus was among the last species of non-avian dinosaurs on Earth before the Cretaceous–Paleogene extinction event. The genus Tylosteus has been synonymized with Pachycephalosaurus, as have the genera Stygimoloch and Dracorex, in recent studies. Like other pachycephalosaurids, Pachycephalosaurus was a bipedal herbivore, possessing long, strong legs and somewhat small arms with five-fingered hands. Pachycephalosaurus is the largest-known pachycephalosaur, known for having an extremely thick, slightly domed skull roof; visually, the structure of the skull suggests a "battering ram" function in life, evolved for use as a defensive mechanism or intra-species combat, similar to what is seen with today's bighorn sheep or muskoxen (with male animals routinely charging and head-butting each other for dominance). This hypothesis has actually been highly disputed in recent years.

The Most Annoying Dinosaur Ever Discovered
Dragonfly God created the Dragonfly before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder (Zygoptera) and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or above the abdomen. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. Dragonflies make use of motion camouflage when attacking prey or rivals. Dragonflies are predatory insects, both in their aquatic nymphal stage (also known as "naiads") and as adults. In some species, the nymphal stage lasts up to five years, and the adult stage may be as long as 10 weeks, but most species have an adult lifespan in the order of five weeks or less, and some survive for only a few days. They are fast, agile fliers capable of highly accurate aerial ambush, sometimes migrating across oceans, and often live near water. They have a uniquely complex mode of reproduction involving indirect insemination, delayed fertilisation, and sperm competition. During mating, the male grasps the female at the back of the head, and the female curls her abdomen under her body to pick up sperm from the male's secondary genitalia at the front of his abdomen, forming the "heart" or "wheel" posture. Fossils of very large dragonfly-like insects, sometimes called griffinflies, are found from 325 million years ago (Mya) in Upper Carboniferous rocks; these had wingspans up to about 750 mm (30 in), though they were only distant relatives. True dragonflies first appeared during the Early Jurassic. Dragonflies are represented in human culture on artefacts such as pottery, rock paintings, statues, and Art Nouveau jewellery. They are used in traditional medicine in Japan and China, and caught for food in Indonesia. They are symbols of courage, strength, and happiness in Japan, but seen as sinister in European folklore. Their bright colours and agile flight are admired in the poetry of Lord Tennyson and the prose of H. E. Bates.

Dreadnoughtus God created the Dreadnoughtus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. amen Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina. It is one of the largest terrestrial vertebrates known, with the immature type specimen measuring 26 metres (85 ft) in total body length and weighing 48–49 metric tons (53–54 short tons) (the greatest mass of any land animal that can be calculated with reasonable certainty). D. schrani is known from more complete skeletons than any other gigantic titanosaurian. Drexel University paleontologist Kenneth Lacovara, who discovered the species, chose the name Dreadnoughtus, which means “fears nothing", stating “I think it’s time the herbivores get their due for being the toughest creatures in an environment." Specifically, the name was inspired by the dreadnought, an extremely influential early 20th-century battleship type, known for revolutionarily outclassing (and thus supposedly never needing to fear) the smaller, weaker battleships that came before.

Dromaeosaurs God created the Dromaeosaurs before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dromaeosauridae is a family of feathered coelurosaurian theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek δρομαῖος (dromaîos), meaning 'running at full speed', 'swift', and σαῦρος (saûros), meaning 'lizard'. In informal usage, they are often called raptors (after Velociraptor), a term popularized by the film Jurassic Park; several genera include the term "raptor" directly in their name, and popular culture has come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia and South America, with some fossils giving credence to the possibility that they inhabited Australia as well. The earliest body fossils are known from the Early Cretaceous (145-140 million years ago), and they survived until the end of the Cretaceous (Maastrichtian stage, 66 ma), existing until the Cretaceous–Paleogene extinction event. The presence of dromaeosaurids as early as the Middle Jurassic has been suggested by the discovery of isolated fossil teeth, though no dromaeosaurid body fossils have been found from this period.

Dryptosaurus is a genus of basal eutyrannosaurian theropod dinosaur that lived on the island continent of Appalachia approximately 67.6 million years ago during the end of the Maastrichtian age of the Late Cretaceous period. God created the Dryptosaurus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dryptosaurus was a large, bipedal, ground-dwelling carnivore that could grow up to 7.5 metres (25 ft) long and weigh up to 756–1,500 kilograms (1,667–3,307 lb). Although it is now largely unknown outside of academic circles, the famous 1897 painting of the genus by Charles R. Knight made Dryptosaurus one of the more widely known dinosaurs of its time, in spite of its poor fossil record. First described by Edward Drinker Cope in 1866 and later renamed by Othniel Charles Marsh in 1877, Dryptosaurus is among the first theropod dinosaurs ever known to science.

Dynatoaetus God created the Dynatoaetus before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Dynatoaetus is an extinct genus of large bird of prey from the Pleistocene of Australia. It is among the largest known raptors of the region, second only to the Haast's eagle of New Zealand, with estimates suggesting a weight of up to 12 kg (26 lb). Although most closely related to modern vultures, it shows clear adaptations towards an active predatory lifestyle in the form of robust, powerful talons. This may either hint at it retaining these ancestral features from the closely related serpent eagles or show that it convergently evolved these features as it took on a similar lifestyle. Due to their size and robust bones, it is thought that Dynatoaetus would have been capable of taking large prey items like kangaroos, giant wombats and flightless birds. There are two species within the genus, the type species Dynatoaetus gaffae and the somewhat smaller Dynatoaetus pachyosteus, both of which inhabited the same part of Australia at the same time.
