Doliosauriscus

12-foot-long dinocephalian therapsids of the genus Doliosauriscus face off in a dry mid-Permian landscape 265 million years ago in what is today Russia. On the horizon is a synapsid of the genus Dimetrodon. Vegetation includes various ferns and cycads.

Similar to its better-known relative Titanophoneus, Doliosauriscus was a carnivore, one of the largest predators of its time with large dagger-like canines in front and sharp incisors and flat molars in back for grinding up flesh.
