In Depth

       Deuterosaurus was a dinocephalian therapsid that lived in what is now Russia during the mid Permian.‭ ‬Skulls of Deuterosaurus range in size from about‭ ‬23‭ ‬centimetres for smaller species,‭ ‬to about‭ ‬80‭ ‬for particularly large species.‭ ‬These larger species would make Deuterosaurus one of the larger land animals of the Permian.‭ ‬Dinocephalian therapsids are usually perceived as being herbivorous,‭ ‬but the dentition of Deuterosaurus would also have been useful for tearing out chunks of flesh from animals.‭ ‬This has led to speculation that Deuterosaurus may have augmented its diet with meat,‭ ‬though the large physical size of the body would not be that well suited for chasing down prey.‭ ‬Instead,‭ ‬Deuterosaurus may have scavenged for carrion,‭ ‬perhaps even bullying predators away from their own kills.
