Pre-dinosaur Apex Predator - Gorgonopsid
Gorgonopsids (Gorgonopsia) are theriodonts, a major group of therapsids that included the ancestors of mammals (that includes humans). Gorgonopsians evolved in the Middle Permian (270mya) becoming the apex predator of its time, but then became a victim of the ‘Great Dying” at the end of the Paleozoic. This was all before the rise of dinosaurs, maybe even ‘cooler’ than dinosaurs?!
Below are links to a one-minute video by Kelsie Abrams (Fossil Lab Manager at the Burke Museum in Seattle) on creating a mold and a replica of a small bone from a Goronopsid, and a three-minute video with Dr. Luis Chiappe of the LA Natural History Museum with a brief look at the Gorgonopsid.
