Coelophysis americanum (meaning "American hollow form"), also known as the hodag, is a species of diurnal coelophysid theropod dinosaur that originally lived approximately 216 to 196 million years ago during the Triassic Period in what is now the southwestern United States and in Africa, 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.
It is a small, slenderly-built, ground-dwelling, bipedal carnivore, that can grow up to 3 m (9.8 ft) long, and normally feeds on smaller animals, carrion, and/or man-made food when alone, but can hunt animals as big as cattle when hunting in packs, but only during times of hardship. The lifecycle of Coelophysis americanum is very similar to birds and crocodilians, laying eggs about as much eggs and as often as fast-reproducing gamebirds, the eggs hatch around 1.5-2 months after being laid, and the hatchlings are cared for by their parents until they are subadults, when they must fend for themselves.
However, one incident occurred in November 4th, 2039, at 5:21 AM, when a shipping truck containing around 25 live adult Coelophysis americanum had toppled over, killing a driver and 7 Coelophysis americanum in a process, on a road near Lake Tahoe, the remaining Coelophysis americanum escaped into the wilderness. Ever since that incident, Coelophysis americanum are now found throughout North America, even in cold forests of Alaska and Canada, possibly due to Coelophysis americanum containing genes of cold-resistant birds and non-avian reptiles. Coelophysis americanum tolerates habitat loss and adapts really well into cities and suburbs, where large numbers of Coelophysis americanum, if there's enough food, can congregate, resembling a scene of massive Coelophysis flocks in Walking with Dinosaurs episode one. Despite being able to hunt large animals in packs, Coelophysis americanum in cites and suburbs have learned not to hunt domesticated animals or humans, as any predators that hunt humans or domestic animals aren't tolerated, and Coelophysis americanum are completely tame towards pets and humans.
