Gorgonopsids (or gorgonopsians) are a clade of extinct therapsids, with the type genus being Gorgonops. Gorgonopsids would've lived in the Permian period, 252 million years ago. Look at the sub-pages in this page to learn more about this majestic creature.
Although they didn't appear in Jurassic Park, these big critters appear in "Walking With Monsters," a BBC documentary, as well as "Dinosaur Revolution," for a small part before going extinct.
Here are some pictures of these majestic superpredators!
