Gorgonopsids were a group of prehistoric reptiles that lived during the late Permian period, around 260 million years ago. They are known for their distinctive features, including large canine teeth and a robust skull. Gorgonopsids were part of the larger group called therapsids, which are ancestors of modern mammals. These creatures were apex predators of their time, hunting smaller animals and competing with other species for food. Gorgonopsids varied in size, with some reaching lengths of over 3 meters. Their adaptations, such as strong jaws and keen senses, made them effective hunters in their ecosystems.
