Crassigyrinus (SciiFii)

Crassigyrinus palusterrorem (name meaning "swamp terror thick tadpole") is a species of carnivorous stem tetrapod from the Early Carboniferous of Scotland and possibly Greer, West Virginia, as an extinct species of Crassigyrinus and was once extinct, but has since been brought back from extinction by SciiFii and now lives in Paleozoic Park located in Downey, California. Crassigyrinus palusterrorem is a large tetrapod, growing on average up to 2 meters in length, coupled with tiny limbs and unusually large jaws, and due to those features, it is fully aquatic. Crassigyrinus palusterrorem is taxonomically enigmatic, having confused paleontologists and scientists for many years with its apparent fish-like and tetrapod features. Before the species' revival by SciiFii, it was traditionally placed within the group Labyrinthodontia along with many other early tetrapods, with some paleontologists have even considered it as the most basal Crown group tetrapod, while others hesitate to even place it within the Tetrapoda superclass, and so far, even with the species species' revival, scientists still haven't figured out what group does Crassigyrinus palusterrorem belongs to. Crassigyrinus palusterrorem has unusually large jaws, enabling it to eat other animals it can catch and swallow. It has two rows of sharp teeth in its jaws, the second row having a pair of fangs. Crassigyrinus has large eyes, giving it the ability to see through murky waters and see well in the dark, making the animal nocturnal. It is a solitary animal that lives in most of its life alone except during the breeding seasons. There are feral breeding populations of Crassigyrinus palusterrorem living in the Everglades of Florida, possibly as a result of illegal pet trade, and may be invasive due to slight competition for crocodilians for food and preying on some endangered indigenous birds and mammals.
