Dromaeosaurus (SciiFii)

***Dromaeosaurus borealis*** (name meaning "boreal swift running lizard"), also known as the **Arctic goblin**, is a species of non-avian theropod dinosaur which originally lived during the Late Cretaceous period (middle late Campanian), sometime between 80 and 69 million years ago, in Alberta, Canada and the western United States, as an extinct species, ***Dromaeosaurus albertensis***, and was once extinct, but has since been brought back from extinction by SciiFii. *Dromaeosaurus borealis* is a medium-sized animal, growing to be about 6.6 feet (2 meters) in length and 15 kilograms (33 lb) in weight. It It is a carnivore and its mouth is full of sharp teeth, and it has a sharply curved "sickle claw" on each foot, which are used to help it pin down its prey before using its sharp teeth to rip out chunks of flesh. Despite its sickle-like claws, *Dromaeosaurus borealis* does not normally hunt animals much larger than itself and only preys on animals that are slightly larger than itself (such as mule deer) and prey animals smaller than itself. It is a solitary animal that spends throughout most of its entire life alone except during the breeding seasons or if it has a mate it lives with, as this species mates for life. *Dromaeosaurus borealis* was originally planned to be included in **Cretaceous Park** located at Sacramento, California, however, due to intruders breaking into the park's laboratory and stealing *Dromaeosaurus borealis* eggs to sell them into illegal pet trade, there are now successful breeding populations of *Dromaeosaurus borealis* living in the wilderness across northern United States, most of Canada, and Alaska, where they are, by all accounts, thriving due to abundant prey items and being adapted to freezing temperatures thanks to its thick, fluffy feathers used for insulation. Like the living *Velociraptor* species, *Dromaeosaurus borealis* is highly adaptable and does not prey on humans, nor their pets or livestock, and they do not carry any diseases or viruses, due to the fact that SciiFii's animals were all created to be completely immune to diseases and viruses, so humans tolerate their presence.
Dingum

A **dingum** (*Velludorsum venenum*) is a species of omnivorous bipedal partially-feathered non-avian maniraptoran dinosaur that was created by SciiFii and introduced to Australia to help boost biodiversity. The dingum is distinguished by its tall sail on its back, which is not formed by bones, but by folds of skin, containing varieties of toxins that it obtains from its diet of insects that possess the substances. Despite being venomous, the venom is not lethal to humans, dogs, or common native wildlife, and is only deadly to feral cats, cane toads, some large venomous snake species, and saltwater crocodiles, it uses its venom as a defense against predators. The conservation status of the dingum is **Least Concern** due to successful conservation efforts, its wide distribution in Australia, and its ability to adapt to life in cities and suburbs.
Atractosteus africanus

The **African gar** (*Atractosteus africanus*) is a species of gar that originally lived from the Cretaceous period of Niger as well as France until the end of the Cretaceous, during the Maastrichtian, and was once extinct but has since been brought back from extinction by SciiFii and introduced to the modern lakes and rivers of Africa to help boost biodiversity. African gars, like other gars, are often referred to as "primitive fishes" or "living fossils" because they have retained some morphological characteristics of their earliest ancestors, such as a spiral valve intestine, which is also common to the digestive system of sharks, and the ability to breathe both air and water. Like the American alligator, the African gars have broad snouts and long, sharp teeth. The African gar can grow to be around the size of an alligator gar and, like them, can sometimes grow up to 10 ft (3.0 m) in length. The body of an African gar is torpedo-shaped, usually brown or olive, fading to a lighter gray or yellow ventral surface. Their scales are not like the scales of other fishes; rather, they are ganoid scales, which are bone-like, rhomboidal-shaped scales, often with serrated edges, and covered by an enamel-like substance. Ganoid scales are nearly impenetrable and are excellent protection against predation. Unlike most other gar species and like the alligator gar, the upper jaw of an African gar has a dual row of large, sharp teeth that are used to impale and hold prey. African gars are stalking, ambush predators, primarily piscivores, but they also ambush and eat water fowl and small mammals they find floating on the water's surface. The conservation status of the African gar is **Least Concern** due to successful conservation efforts and the African gar's wide range.
Diplodocus V5

***Diplodocus turciagutture*** (name meaning "turkey-throated double beam") is a species of giant sauropod part of the family of sauropods, Diplodocids. It originally lived during the Late Jurassic in what is now Colorado, Wyoming, Utah, and Montana, and was once extinct, but has been brought back from extinction by SciiFii and, unlike Sciifii's first *Diplodocus* species, has been introduced to the open woodlands and grasslands across North America to help boost biodiversity. *Diplodocus turciagutture* is a herbivore like most advanced sauropods, feeding mainly on leaves of ferns, cyacads, horsetails, conifers, and among other evergreen trees, but can sometimes feed on fruits and nuts. It is one of the longest dinosaurs alive today, growing to be around 88.6 feet (27 meters) long and weigh as much as two bull African elephants. It is a social herd-dwelling animal, living in groups up to around 10-15 at a time in most cases, but can occasionally live in herds as much as around 50-75 if there's enough space and food for them. The females live in herds throughout almost all their lives, while males live in solitary lives, in a manner similar to elephants, and during mating seasons, males visit nearby herds and clash with other males until one backs down, that's when a winning male *Diplodocus turciagutture* gets a right to mate with any of the herds' females. The conservation status of *Diplodocus turciagutture* is **Least Concern** due to successful conservation efforts and the animal's wide range.
Domestic hyena

The **domestic hyena** (*Crocuta crocuta domestica*), also known as the **house hyena**, is a subspecies of spotted hyena (*Crocuta crocuta*) that originally did not exist, but has since been created by SciiFii due to demands for more kinds of large pets. The domestic hyena can be distinguished from its wild ancestors by is slightly smaller, weaker jaw, as well as floppy ears in many domestic hyena breeds, and varied fur length and coloration depending on a breed. The domestic hyena breeds range in size from terrier-sized breeds to the largest breeds about the size of a large wild spotted hyena. Just like other domestic animals, the domestic hyenas are very loyal, docile, and affectionate towards their owners. The domestic hyena is among the most popular domestic mammals (re)created by SciiFii due to hyenas becoming popular with many people, even going as far as to being alternatives to guide dogs and sheepdogs due to their boldness and intelligence greater than any domestic dog breed.
Dolpherret

The **dolpherret** (*Tripodogale konti*) is a species of fully terrestrial cetacean that originally did not exist, but has since been created by SciiFii and introduced throughout the subtropical and temperate forests of the Azores archipelago to help boost biodiversity. It was difficult to create due to its "third leg", which is actually its modified tail, however, SciiFii has successfully created this animal without any side effects (illnesses, etc). The dolpherret is a rather small animal, growing to be about the size of the mainland raccoon (*Procyon lotor*). The dolpherret is an omnivore that is mostly carnivorous, feeding on insects, smaller vertebrates, and, occasionally, carrion, filling the similar ecological niche to the mainland ferrets and weasels, but it can sometimes also feed on fruits, leaves, roots, tubers, and bulbs to supplement its diet. It is nocturnal due to predation from megasquids, using its wiskers, rather than its melon, which is degenerated due to being a land animal, in order to find its way around in the dark. Unlike several other terrestrial whales and most land mammals in general, the dolpherret has developed a thick, keratin beak to help it feed on tougher foods than most terrestrial whales. Unlike most other mammals, having a tough beak doesn't pose a significant problem for suckling its young, since it retained its aquatic relatives' method of squirting milk directly into the mouths of its calves. It is a solitary animal in most of its life except during breeding seasons, when males try to find females to mate with. The conservation status of the dolpherret is **Least Concern** due to successful conservation efforts, the dolpherret's wide range and its tolerance to many of the human activities.
Desmatosuchus

***Desmatosuchus triassicus*** (name meaning **Triassic link crocodile**) is a species of archosaur belonging to the Order Aetosauria. It originally lived during the Late Triassic of North America, and was once extinct, but has since been brought back by SciiFii and now lives in the **Triassic Dinosaurs** section of **Cretaceous Park** located at Sacramento, California. *Desmatosuchus triassicus* is a large quadruped upwards of 4.5 meters in length, and is a herbivore, unlike (most) crocodilians and relatives, feeding mainly on leaves, fruits, shrubs, cycads, ferns, and horsetails. It is heavily armored, and its carapace is made up of two rows of median scutes surrounded by two more rows of lateral scutes. The lateral scutes have well-developed spine-like processes which points out laterally and dorso-posteriorly, used for protection against predators. *Desmatosuchus triassicus* is unique among aetosaurs in that its species are the only known aetosaurs that lack teeth on their premaxillae, instead, being covered by a horny forked beak-like sheath. In most of its life, *Desmatosuchus triassicus* behaves very similar to an over-sized iguana, being normally solitary, but during mating seasons, males clash each other by ramming one another hip-to-hip, until one backs down and the other wins a right to mate. The lifecycle of a *Desmatosuchus triassicus* is similar to that of crocodilians, where mothers take care of the eggs for around 2-4 months until they hatch into baby *Desmatosuchus triassicus*, the mothers care for their hatchlings until they are old enough to fend for themselves.
Diabloceratops

***Diabloceratops satanicus*** is a species of centrosaurine ceratopsian dinosaur that originally lived around 79.9 million years ago during the latter part of the Cretaceous Period in what is now Utah, in the United States, as an extinct species, *Diabloceratops eatoni*, and the genus *Diabloceratops* was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern swamps, forests, open woodlands, and some grasslands to help boost biodiversity. *Diabloceratops satanicus* is a medium-sized, moderately built, ground-dwelling, quadrupedal herbivore, that can grow on average up to about 5.5 meters (18.0 ft) long. It primarily feeds on leaves, conifer needles, fruits, nuts, seeds, horsetails, ferns, and cycads. It is a solitary animal in most of its life except during breeding seasons, when males challenge other males to win a right to mate with females. The conservation status of the *Diabloceratops satanicus* is **Least Concern** due to successful conservation efforts and its wide range across North America.
Domestic dodo

The **domestic dodo** (*Raphus cucullatus familiaris* or *Raphus familiaris*) is a species of flightless pigeon that originally did not exist, but has since been created by SciiFii due to demands for dodos as pets. The domestic dodo is most closely related to the pure wild dodo (*Raphus cucullatus*). Unlike wild dodos, however, the domestic dodos are much more adaptable to a wider range of habitats and can feed on a wider assortment of vegetation. Like wild dodos, the domestic dodos are not dimwitted birds as pop culture shows, but are about as smart as flying pigeons. There are more than 200 breeds of domestic dodos that are bred across the world, ranging from about the size of a mallard duck to the largest breeds that are about the size of an emu. The domestic dodo is one of the most popular non-parrot birds as pets, due to being easy to keep, train, and care for, as well as being able to breed extremely well in captivity.
Doedicurus

The **club-tailed glyptodont** (*Doedicurus argentinus*) is a species of large Ankylosaur-like glyptodont that originally lived in South America during the Pleistocene and was once extinct, but has since been brought back from extinction by SciiFii and introduced to modern North and South America to help boost biodiversity. The club-tailed glyptodont is one of the largest known glyptodont species, growing to be around 4 meters long and weigh 1,400 kg (3,100 lb), and is one of the better-known members of the family. Like most glytodonts, it is mostly a quadrupedal animal, but unlike other glytodonts, it is sometimes able to stand on two legs like many other xenarthrans. It is noticeable from other glyptodonts by the fact that it has a spiked tail club, which weigh around 40 and 65 kg (88 or 143 lb) in life, and it swings this in defense against predators and in fights with other Doedicurus at speeds of 11 m/s (40 km/h; 25 mph). It is a grazing herbivore, but due to its slow metabolism, it is unable to chew grass effectively. The conservation status of the club-tailed glyptodont is **Least Concern** due to successful conservation efforts, the club-tailed glytpodont's wide range, and its tolerance to habitat disturbance much like whitetail deer and mule deer, allowing it to live in the rural areas as well as some areas of the cities and suburbs in its range.
Crocogator

The **crocogator** (*Crocodylogator amphibius*) is a species of crocodilian belonging to the alligator family Alligatoridae, most closely related to the genus *Alligator* of North America and Asia, that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests and wetlands across South America to help boost biodiversity. The crocogator is a rather large species of crocodilian, reaching about 1.5–2.1 metres (5–7 feet) in length and weighing 36–45 kilograms (80–100 lb) as an adult. As its name suggests, the crocogator resembles a hybrid between a crocodile and an alligator, with a broad snout like an alligator and lower jaw teeth that sticks out like a crocodile, and it has a typical body plan and armor typical of alligatorids. The crocogator's diet consists mainly of fish, frogs, other reptiles, birds, mammals, and carrion, and will occasionally eat plants as well, although this behaviour is uncommon. The crocogator is largely amphibious like most crocodilians. The crocogator is a solitary animal throughout its life except during the breeding seasons. The conservation status of the crocogator is **Least Concern** due to successful conservation efforts and the crocogator's wide range.
Dromomeron

***Dromomeron modernum*** is a species of lagerpetonid pterosauromorph archosaur that originally lived around 220 to 211.9 million years ago as several extinct species of *Dromomeron* of southwestern United States and northwestern Argentina. This animal was once extinct since the Late Triassic, but has since been brought back from extinction by SciiFii. *Dromomeron modernum* was originally planned to be included in **Cretaceous Park** located in Sacramento, California. However, in December 11th, 2040, some intruders, possibly animal rights activists released all 15 *Dromomeron modernum* to the wilderness, despite SciiFii treating all of its animals with care and respect, and over time, the population of *Dromomeron modernum* have exploded from just 15 individuals to almost a million individuals throughout western and southwestern North America due to abundant food sources and less natural predators than during the Late Triassic. Despite its dinosaur-like appearance and locomotion like a bipedal dinosaur, it is not a dinosaur and only resembles dinosaurs due to convergent evolution, yet it can be mistaken at first glance for a *Compsognathus* because of its resemblance. Surprisingly, the closest living relatives of *Dromomeron modernum* are the pterosaurs, both living and extinct species, as genes and DNA analysis from scientists have confirmed. It is a bipedal-running carnivore that primarily feeds on insects, spiders, scorpions, millipedes, centipedes, crustaceans, mollusks, fish, frogs, small lizards, eggs, carrion, small mammals, and some man-made food. It is a solitary animal that lives in most of its life alone except during breeding seasons, when the males' coat of pycnofibers turn to bright orangish-red with a greenish-gray capped head in order to attract the dull-colored females. The female *Dromomeron modernum* can lay around 25-40 eggs at a time around 2 months after mating, and the eggs hatch about 3.5 months afterwards, with the chicks being cared for by their mothers until they're nearly fully-grown, when they must fend for themselves.
Deltatheridium

The **Mongolian false opossum** (*Deltatheridium mongoliensis*, name meaning 'Mongolian triangle beast" or "Mongolian delta beast"), also known as the **Mongolian false possum**, is a species of metatherian that originally lived in what is now Mongolia during the Upper Cretaceous, *circa* 80 million years ago, as an extinct species of *Deltatheridium* and was once extinct, but has since been brought back from extinction by SciiFii and now lives in **Cretaceous Park** located at Sacramento, California, as an animal ambassador. The Mongolian false opossum is a basal metatherian, which places it near to the start of the lineage that led to the marsupials, such as kangaroos, wallabies, koalas, and opossums. It has a length of about 15 cm (5.9 inches). It is a carnivorous animal that primarily feeds on insects, scorpions, spiders, carrion, and any vertebrate smaller than itself.
East Asian lion

The **East Asian lion** (*Panthera leo sinensis*), also known as the **Chinese lion**, is a subspecies of lion that originally did not exist, but has since been created by SciiFii and introduced throughout the open woodlands, grasslands, and shrublands across mainland Southeast Asia and East Asia, primarily China, to help boost biodiversity. The East Asian lions range in colour from light to dark tawny. Male lion skins have manes of varying colouration and length. Head-to-tail length of males vary from 2.35 to 2.8 meters (7 feet 9 inches to 9 feet 2 inches), and of females around 2.5 meters (8 feet 2 inches). Skull size varies from 30.85 to 37.23 centimeters (1 feet 0.15 inches to 1 feet 2.66 inches). Some manes extend over the shoulder and under the belly to the elbows. The mane hair is 8 to 22 centimeters (3.1 inches to 8.7 inches) long. East Asian lions are known to live in pairs or in small family groups comprising a male and female lion with one or two cubs. The size of prides are very similar to prides of lions living in sub-Saharan African habitats. The main prey items of the East Asian lions include Central Asian red deer (*Cervus hanglu*), sika deer (*Cervus nippon*), wapiti (*Cervus canadensis*), wild boar (*Sus scrofa*), Przewalski's horse (*Equus ferus przewalskii*), wild Bactrian camel (*Camelus ferus*), macaques, and, occasionally, giant panda (*Ailuropoda melanoleuca*). The conservation status of the East Asian lion is **Vulnerable** due to some habitat loss and, historically, poaching, however, thanks to the conservationists, the East Asian lion is a protected species.
Cretalamna

The **dwarf megatooth shark** (*Cretalamna pygmiensis*) is a species of otodontid shark that originally lived about 103 to 46 million years ago from the  Late Cretaceous to Eocene epochs as an extinct species of *Cretalamna* and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern oceans worldwide to help boost biodiversity. The original species of *Cretalamna* is considered by many to be the ancestor of the largest sharks to have ever lived, *Carcharocles angustidens*, and *Carcharocles megalodon*. The pygmy megatooth shark is a medium-sized shark with a total length of 2.3 – 3 meters. It has a fusiform-like body plan comparable to those of native modern lamniforme sharks. Given the size of the pygmy megatooth shark's teeth relative to its body size, its caudal fin is not used for stunning prey (as is the case for thresher sharks). Instead, the caudal fin of the pygmy megatooth shark is more similar to that of the great white shark. The pygmy megatooth shark is a generalist predator and scavenger, preying mainly on large bony fish, turtles, mosasaurs, pinnipeds medium-sized whales, squids, and other sharks. The conservation status of the pygmy megatooth shark is **Least Concern** due to successful conservation efforts, the pygmy megatooth shark's wide range, and its tolerance to most of human activities. It is also completely tame, docile, peaceful, and gentle towards people, so the people seem to tolerate the pygmy megatooth shark's presence even in public beaches.
Dinictis

The **lesser false saber cat** (*Dinictis minor*), also known as the **American leopard** and the **brown panther**, is a species of the Nimravidae, a family of feliform mammalian carnivores, known as "false saber-toothed cats", that originally lived in North America from the Late Eocene to Early Miocene epochs (37.2—20.4 million years ago), existing for about 16.8 million years, as an extinct species of *Dinictis* and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern forests, swamps, open woodlands, grasslands, and shrublands across North America to help boost biodiversity. The lesser false saber cat belongs to the subfamily, Nimravinae. The lesser false saber cat has a sleek body around 1.1 metres (3.6 ft) in body length, with short legs 0.6 metres (2.0 ft) high with only incompletely retractable claws, powerful jaws, and a long tail. Dinictis walks plantigrade (flat-footed), unlike true felids. It looks very similar to a small leopard and its mode of life is similar to that of a leopard, hence its name. It is not so particular about its food as its distant relatives, since the reduction of its teeth is still in the early stages and the lesser false saber cat has not forgotten how to chew. In its own environment, it is a gracile powerful predator that fills the niche similar to the leopards of the Old World. The lesser false saber cat is a solitary animal that prefers to spend throughout its life alone except during the breeding seasons. The conservation status of the lesser false saber cat is **Least Concern** due to successful conservation efforts, the lesser false saber cat's wide range and its tolerance to many of the human activities.
Dinheirosaurus

***Dinheirosaurus europeansis*** is a species of diplodocid sauropod dinosaur that originally lived in what is now Portugal during the Late Jurassic as an extinct species, *Dinheirosaurus lourinhanensis*, which may instead represent a species of *Supersaurus*, and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern open woodlands, grasslands, shrublands, and scrublands across Europe to help boost biodiversity. *Dinheirosaurus europeansis* is an average sized diplodocid, and has an elongated neck and tail. *Dinheirosaurus europeansis* has an average length of around 25 meters (82 feet). *Dinheirosaurus europeansis* is a herbivore like most advanced sauropods, feeding mainly on leaves of ferns, cyacads, horsetails, conifers, and among other evergreen trees, but can sometimes feed on fruits and nuts. It is a social herd-dwelling animal, living in groups up to around 10-15 at a time in most cases, but can occasionally live in herds as much as around 50-75 if there's enough space and food for them. The females live in herds throughout almost all their lives, while males live in solitary lives, in a manner similar to elephants, and during mating seasons, males visit nearby herds and clash with other males until one backs down, that's when a winning male *Dinheirosaurus europeansis* gets a right to mate with any of the herds' females. The conservation status of *Dinheirosaurus europeansis* is **Least Concern** due to successful conservation efforts and the animal's wide range.
Dwarf peccary

The **dwarf peccary** (*Nanotayassus minor*), also known as the **pygmy peccary**, is a species of small pig-like hoofed mammal of the family **Tayassuidae** (New World pigs) that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, swamps, marshlands, forests, open woodlands, grasslands, and shrublands across North America to help boost biodiversity. The dwarf peccary's skin is dark brownish-gray with a few dark hairs. Its head is tapered with a slight crest of hair on the forehead and on the back of its neck. Its iris is hazel brown. The dwarf peccary is the smallest living species of peccary, being usually about 20–25 cm (8–10 inches) high and 45.5–51 cm (18–20 inches) long with a short tail of about 2.5 cm (0.98 inches). It usually weighs around 3.2–5.4 kg (7–12 lb) on average. Adult males have the upper canines visible on the sides of their mouths. Reds are born grayish-pink, becoming grayish-brown with yellow stripes along the body length. They live for about twelve years, becoming sexually mature at one year old. They breed seasonally in Spring before giving birth to a litter of three to six after a gestation of 100 days. In the wild, they make small nests by digging a small trench and lining it with vegetation. During the heat of the day, they stay within these nests. They mainly feed on roots, tubers, insects, rodents, and small reptiles. The conservation status of the dwarf peccary is **Least Concern** due to successful conservation efforts, the dwarf peccary's wide range and its tolerance to many of the human activities.
Didelphodon

The **pouched otter** (*Didelphodon sciifii*) is a species of stagodont metatherian mammal that originally lived in North America during the Late Cretaceous as an extinct species of *Didelphodon* and was once extinct, but has since been brought back from extinction by SciiFii and included in **Cretaceous Park**, located in Sacramento, California, as an animal ambassador. However, due to illegal pet trade, some of the pouched otters have established breeding populations throughout the rivers, lakes, and wetlands of North America, which are, by all accounts, thriving. It is about the size of a little-more-than-average-sized house cat or a Virginia opossum, measuring over a meter long, including its tail, and weigh up to 5 kilograms. The pouched otter also possesses an extremelly powerful bite force for it's size, one of the highest of all known mammals, helping it to become one of the earliest marsupial relatives to become an active predator-scavenger. The pouched otter is semi-aquatic and mainly feeds on fish, crustaceans, and mollusks, but can also feed on carrion to supplement its diet. It is a solitary animal in most of its life, however, during breeding seasons, males mate with females for life like some other small mammals and unlike most others. The conservation status of the pouched otter is **Least Concern** due to successful conservation efforts, the pouched otter's wide range, and its tolerance to most of human activities, including being able to adapt to life in the cities and suburbs.
Dakosaurus

***Dakosaurus marinus*** is a species of crocodylomorph within the family Metriorhynchidae that originally lived during the Late Jurassic and Early Cretaceous in what is now Europe, Mexico, and Argentina as two extinct species, *Dakosaurus maximus* and *Dakosaurus andiniensis*, and the genus itself was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern world's oceans to help boost biodiversity. *Dakosaurus marinus* is a relatively large reptile, growing to be about 13 to 16 feet (4-5 meters) in length, with teeth that are serrated and compressed lateromedially (flattened from side to side). *Dakosaurus marinus* is a carnivore that, unlike its relatives such as *Geosaurus*, is an apex predator that primarily feeds on sea turtles, plesiosaurs, ichthyosaurs, small mosasaurs, large game fish (including tunas), sea birds, and small-to-medium-sized marine mammals. Unlike native modern crocodilians, *Dakosaurus marinus* is a fully-aquatic reptile that spends throughout all its entire life out at sea. The extent of its adaptation to a marine lifestyle means that it mates at sea, much like plesiosaurs and ichthyosaurs, being unlike sea turtles. Because of being entirely aquatic, *Dakosaurus marinus* gives birth to live young similarly to marine mammals, with the young being born tail-first to avoid drowning before the young takes the first breath of air. *Dakosaurus marinus* is a solitary animal that spends throughout most of its life alone except during the breeding seasons. The conservation status of *Dakosaurus marinus* is **Near Threatened** due to overhunting from poachers, however, thanks to the conservationists, *Dakosaurus marinus* is a protected species.
Crowned brontothere

The **crowned brontothere** (*Brontochlos coronatus*) is a species of brontothere that originally did not exist, but has since been created by SciiFii and introduced throughout the Patagonian Steppe and nearby grasslands of South America to help boost biodiversity, making it the only brontothere native to South America. The crowned brontothere is rather small compared to most other brontotheres, growing to be about the size of a sheep or around 1 meter (3.3 feet) tall, and are built more like tapirs or wild boars than their rhino-like relatives. Although they are able to move faster in the more open environments, their main defense is actually their highly social herding behavior, relying on strength in numbers and collectively mobbing predators, although many males are solitary animals outside of breeding season and/or when the outsider males win the right to lead the herds against the leading bulls, who are then exiled from the herds to start their solitary lives. Males also have elaborate head ornamentation, resembling mammalian versions of ceratopsian frills and horns, with ossicone-like projections on the back of their skulls as well as on their noses. Unlike most other brontotheres, the crowned brontothere is adapted for grazing on grasses. Mating season occurs between November and February, during which males often fight violently to establish dominance and breeding rights. Eleven-and-a-half months later, a single calf is born. Crowned brontothere calves are able to walk immediately after birth. Male crowned brontothere calves are chased off from the herds by the dominant males around one year of age. The conservation status of the crowned brontothere is **Least Concern** due to successful conservation efforts, the crowned brontothere's wide range and its tolerance to many of the human activities.
Diprotodon

The **giant wombat** (*Diprotodon modernus*, name meaning "modern two forward teeth") is a species of marsupial native to the forests, woodlands and grasslands of Australia. It is largest known marsupial to have ever lived, about 3 metres (9.8 ft) from nose to tail, standing 2 metres (6.6 ft) tall at the shoulder and weighing about 2,790 kilograms (6,150 lb). Much like their smaller relatives, the burrowing true wombats and the arboreal koalas, the giant wombat is a herbivore, mainly eating leaves, shrubs, and some grasses. It is suggested that diprotodonts (both modern and extinct) may have been an inspiration for the legends of the bunyip, as some Aboriginal tribes identify bones of extinct *Diprotodon* species as those of "bunyips", and have observed giant wombats in the riverbanks, mistaken for the mythical "bunyip". The conservation status of the giant wombat is **Near Threatened** due to some habitat loss and historic poaching, however, the conservationists have protected giant wombats from poachers and preserved the natural habitats of the giant wombats.
Dilophosaurus V1

***Dilophosaurus anthropoceus*** (name meaning *two-crested lizard from age of man*) is a species of theropod dinosaur part of Dilophosauridae family that originally lived in what is now North America during the Early Jurassic, about 193 million years ago, but now exists in modern times (thanks to SciiFii) located in the **Carnivores of the Jurassic** section of **Cretaceous Park** in Sacramento, California. At about 7 meters (23 ft) in length, with a weight of about 400 kilograms) (880 lb), *Dilophosaurus* was originally one of the earliest large predatory dinosaurs, though it is smaller than some later theropods. It is slender and lightly built, being covered in both green, yellow, and brown scales, as well as greenish yellow feathers, and the skull is proportionally large, but delicate. The snout is narrow, and the upper jaw has a gap or kink below the nostril. It has a pair of longitudinal, plate-shaped crests on its skull, similar to a cassowary with two crests used for species recognition and even breeding season to attract mates (when males have bright red crests). The mandible is slender and delicate at the front, but deep at the back. The teeth are long, curved, thin, and compressed sideways. Those in the lower jaw are much smaller than those of the upper jaw. Most of the teeth have serrations at their front and back edges. The neck is long, and its vertebrae are hollow, and very light. The arms are powerful, with a long and slender upper arm bone. The hands have four fingers: the first is short but strong and has a large claw, the two following fingers are longer and slender with smaller claws, and the fourth is vestigial. The thigh bone is massive, the feet are stout, and the toes bare large claws. *Dilophosaurus* is an active and bipedal carnivore, and can hunt large animals; but it also feeds on smaller animals, carrion, and, mainly, fish. Due to the limited range of movement and shortness of the forelimbs, the mouth instead makes first contact with prey. It can grow rapidly, attaining a growth rate of 30 to 35 kilograms (66 to 77 lb) per year early in life. Naturally in its native range and timeline, *Dilophosaurus* is known from the Kayenta Formation, and lived alongside dinosaurs such as *Megapnosaurus* and *Sarahsaurus*, but in modern day Cretaceous Park, it feeds on live fish food, carrion, and, occasionally, live pigs and/or goats. *Dilophosaurus* was featured in the novel *Jurassic Park* and its movie adaptation, wherein it was given the fictional abilities to spit venom and expand a cowl on its neck, as well as being smaller than the real animal (both original and the Cretaceous Park version).
Eastern elk

The **eastern elk** (*Cervus canadensis canadensis*) is a subspecies or distinct population of elk that inhabits the northern and eastern United States, and southern Canada. The eastern elk was once extinct since September 1, 1877, but has since been brought back from extinction by SciiFii and reintroduced to the eastern elk's former range. A full-grown eastern elk bull can weigh up to 1,000 pounds, stand 50-60 inches tall at the shoulder, and carry a rack of antlers six feet in length. Like other elk subspecies or populations, eastern elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark. Male elk have large antlers which they shed each year. Males also engage in ritualized mating behaviors during the rut, including posturing, antler wrestling (sparring), and bugling, a loud series of vocalizations that establishes dominance over other males and attracts females. The conservation status of the eastern elk is **Least Concern** due to successful conservation efforts, the eastern elk's wide range and its tolerance to many of the human activities.
Edestudactylus

***Edestudactylus ichthyodonta*** is a species of rhamphorhynchid pterosaur that originally did not exist, but has since been created by SciiFii. *Edestudactylus ichthyodonta* was originally planned to be included in **Cretaceous Park** located in Sacramento, California, but all 50 pterosaurs of this species have been set loose accidentally, after some staff members left the cages for this species open. Ever since this accident, the populations of *Edestudactylus ichthyodonta* in the wilderness and human settlements across the western United States have exploded from just 50 to more than 750,000 in just a few decades, thanks to the pterosaur's fast and frequent reproduction and varied insect and fish diet. *Edestudactylus ichthyodonta* is a medium-sized pterosaur, having a wingspan of up to around 1.81 meters (5.9 feet) across. It is an carnivore like most of its relatives, feeding primarily on dragonflies, damselflies, beetles, moths, mayflies, waterbugs, flies, gnats, ticks, spiders, crustaceans, snails, slugs, and fish. *Edestudactylus ichthyodonta* is a diurnal animal. It is a solitary animal that lives in most of its life alone except during the breeding seasons. The conservation status of *Edestudactylus ichthyodonta* is **Least Concern** due to successful conservation efforts, the pterosaurs' wide range and its tolerance to most of human activities, including being able to adapt to life in the cities and suburbs, having benefited from human expansion due to many domestic livestock hosting many insects and due to many large animals living in the cities and suburbs.
Corythosaurus

***Corythosaurus americanum*** (name meaning "American helmet lizard") is a species of hadrosaurid "duck-billed" dinosaur that originally lived from the Upper Cretaceous Period, about 77–75.7 million years ago in what is now North America as an extinct species of *Corythosaurus* and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern North American forests and open woodlands to help boost biodiversity. *Corythosaurus americanum* has an average length of 9 metres (30 ft), and has a skull, including the crest, that is 70.8 centimetres (27.9 in) tall, which is used for species recognition and to produce deep trumpeting calls. Like most hadrosaurs, *Corythosaurus americanum* is a herbivore that primarily feeds on leaves, conifer needles, seeds, twigs, and fruits. It is a social animal that lives in herds of up to around 30 individuals at a time. During the breeding seasons, the males' dull brown crests (similar to the females' also brown crests) turn bright orange and males use their crests to display and for vocalizations in order to attract the females. The conservation status of *Corythosaurus americanum* is **Least Concern** due to successful conservation efforts, the animal's wide range and its tolerance to many of the human activities.
Dilong

***Dilong asiaticus*** (name meaning "emperor dragon"), also known as the **pygmy dragon** and the **dwarf dragon**, is a species of basal tyrannosauroid dinosaur that originally lived during the Early Cretaceous in Yixian Formation near Lujiatun, Beipiao, in the western Liaoning province of China, as an extinct species, *Dilong paradoxus*, and was once extinct, but has since been brought back from extinction by SciiFii. It is currently planned to be included in Cretaceous Park located in Sacramento, California, and was originally planned to be included in **Cretaceous Park: Shanghai** located in Shanghai, China, but *Dilong asiaticus* escaped from transport cages, due to the staff members who forgot to shut the transport cages properly. Ever since several *Dilong asiaticus* have escaped, they have established breeding populations throughout China, Mongolia, Russia, and Japan (although that may be due to illegal pet trade), where they are, by all accounts, thriving. *Dilong asiaticus* is a carnivore that primarily feeds on, not only wild ungulates as large as a deer, but also lizards, snakes, small crocodilians, medium-sized reptiles, frogs, fish, and carrion. *Dilong asiaticus* is one of the smallest tyrannosaurs known, only growing to be about 6.6 feet (2 meters) in length on average, and weigh about as much as a human child. *Dilong asiaticus* is covered in thick, yet simple, fur-like feathers that do not resemble bird feathers, and its feathers are used to help keep the animal warm in freezing cold environments. Like other small-to-medium-sized tyrannosaurs, *Dilong asiaticus* is a solitary animal that usually spends throughout most of its life alone except during the breeding seasons or if it has a partner of a different gender that mates for life. The conservation status of *Dilong asiaticus* is **Least Concern** due to successful conservation efforts, the dinosaur's wide range and its tolerance to many of the human activities.
Dwarf white shark

The **dwarf white shark** (*Nanocarcharacles vulgaris*) is a species of small mackerel shark that originally did not exist, but has since been created by SciiFii and introduced throughout the world's oceans to help boost biodiversity. Despite its tiny size, the closest living relative of the dwarf white shark is the much more famous great white shark (*Carcharodon carcharias*). As its name suggests, the dwarf white shark is the world's smallest mackerel shark, growing to be up to 20–25 centimeters (7.9–9.8 inches), and with typical adult sizes ranging from 10–15 centimeters (3.9–5.9 inches). The other distinguishing characteristics of the dwarf white shark includee a slimmer body, slightly more elongated dorsal and pectoral fins, and smaller, more rounded teeth. Like other mackerel sharks, it has an anal fin, five gill slits, eyes without nictitating membranes, and a mouth extending behind the eyes. Due to its small size, it posses no danger towards living mammals, birds, or most reptiles or amphibians, but it can feed on other fish, crustaceans, worms, snails, small amphibians, and, unlike most sharks, commercial fish food. The dwarf white shark is non-migratory, and is able to tolerate pure freshwater and completely still waters, unlike most sharks, making it a very suitable aquarium pet, compared with its close relatives. The dwarf white shark tolerates members of its species extremely well, and up to around 15 individuals can be placed in a large household aquarium. The dwarf white shark is a very fast and frequent breeder and, in just 2.5 months after mating, can give live birth of up to around 30 tiny young at a time and, unlike most sharks, are not cannibalistic. The young of dwarf white sharks can reach sexual maturity at just 1 year and the species can live to be around 70 years. The conservation status of the dwarf white shark is **Least Concern** due to successful conservation efforts, the dwarf white shark's wide range and its tolerance to many of the human activities.
Dinocrocuta

The **greater false hyena** (*Dinocrocuta gigas*) is a species of hyena-like feliform carnivore of the family, Percrocutidae, that originally lived in Asia, and Africa, during the Miocene epoch as an extinct species of *Dinocrocuta* and the genus itself was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern open woodlands, grasslands, shrublands, and scrublands across Africa and Asia to help boost biodiversity. As its name suggests, the greater false hyena is more closely related to cats and nimravids than true hyenas. The greater false hyena is a very large carnivore and has a shoulder height of between 110 centimetres (43 inches) to 130 centimetres (51 inches) and a weight of around 250 kilograms (550 lbs). The greater false hyena has very strong jaws that is able to crush bones of the many animal species. The greater false hyena is an exceptionally powerful predator and scavenger, capable of preying on animals much larger than itself, with the largest recorded prey animals being large rhinoceroses. The greater false hyena is usually a solitary animal that lives alone throughout its life outside of breeding season, but after mating, both males and females form strong bonds for life. The gestation period lasts 73-81 days, with the interval between each pregnancy being 12–14 months typically. The greater false hyshe litters can contain around 1 to 4 pups, with an average of 3. After giving birth, The mother uses dens as birthing areas and she stays close to the pups in the den. The pups are old enough to eat solid food at three to four weeks of age. The pups leave the den around the age of three weeks and are suckled outside. The pups are weaned at the age of five weeks, when they are fed regurgitated meat by their mothers. By seven weeks, the pups begin to take on an adult appearance, with noticeable lengthening in the legs, muzzle, and ears. Once the pups reach the age of eight to 10 weeks, the mother abandons the young for them to fend for themselves. The conservation status oc the greater false hyena is **Vulnerable** due to some habitat loss and poaching, however, thanks to the conservationists, the greater false hyena is a protected species.
Dunkleosteus

***Dunkleosteus edentula*** (meaning "toothless Dunkle bone") is a species of arthrodire placoderm fish that originally lived in Devonian oceans, as an extinct species of *Dunkleosteus* and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern Pacific Ocean to help boost biodiversity. It is one of the largest placoderms to have ever live, growing on average of about 8.79 meters (28.8 ft) long and 4 t (4.4 short tons) in weight. *Dunkleosteus edentula* can quickly open and close its jaw, like suction feeders, and had a bite force of 6,000 N (612 kgf; 1,349 lbf) at the tip and 7,400 N (755 kgf; 1,664 lbf) at the blade edge. Like other placoderms, *Dunkleosteus edentula* has a two-part bony, armoured exterior, which makes it a relatively slow but powerful swimmer. Instead of teeth, *Dunkleosteus edentula* possesses two pairs of sharp bony plates which forms a beak-like structure. Like sharks, *Dunkleosteus edentula* has the ability to internalize egg fertilization, which allows the fish to give birth between 1 and 2 baby *Dunkleosteus edentula* much like live-birthing sharks. Despite its fearsome appearance, it does not hunt marine mammals, birds, or reptiles, instead, its diet composes entirely of fish, crustaceans, sea scorpions, trilobites, and cephalopods. The conservation status of *Dunkleosteus edentula* is **Least Concern** due to successful conservation efforts and the fish's wide range.
