Gorgonopidae

Machine-translated from the Spanish article

The gorgonopsids (Gorgonopsidae, from Greek: "Gorgon face", a monstrous mythological being) are an extinct family of carnivorous therapsids from the Permian period. When these therapsids developed, the pelycosaurs were already in decline, and the gorgonopsids came to be above the other therapsids in the food chain. Many scientists think these therapsids were warm-blooded, unlike their pelycosaur ancestors.
