It was chosen by the developer Soals to be added into the game.
Zupaysaurus was a small, early theropod from the late Triassic era. It was a carnivore, and somewhat resembles other early theropods, such as Coelophysis and Dilophosaurus. Its in-game abilities are still being decided upon, but there is a high possibility that it may feature venom. It is very likely that this creature will not be playable for the public in quite some time.
