Gorgonopsid

this proto mammal is from the late premain. the animal has a bite mark scar from an Allosaurus attack, the animal also has two saber like teeth. one captured individual was named "Sir saber teeth" by Markus brown, later on during a trilobite infestation the animal, a Triceratops nicknamed "Horus" and Opkornius freaked out from the animals and panicked.

later on Sir saber tooth, after getting a horrible tooth ache went on a rampage and attacked a young boy in his room (just like it's parent did) but later on teh same boy after stalking the kid kicked his tooth out and he willingly entered the trailer. this animal is one of the 3 species to appear followed by Leo gorgon ( a made up species) and Gorgonops.

gorgonopsid is one of the few animals capable of killing a future predator in battle, the other animals being triceratops, Mammoth, Leo gorgon, and Carnotaurus. this has been proven by the British ARC, during their stay in the Premain period a Gorgonopsid killed a Future predator by flipping on it's back and crushing the predator

When a Smilodon was captured and used at a big cat park a gorgonopsid was taken to fight the cat, there it was revealed that it was bullet resistant
