       A relative of the genus Moschops,‭ ‬Criocephalosaurus was a tapniocephalid dinocephalian therapsid that lived in South Africa during the Permian.‭ ‬As with relative genera,‭ ‬Criocephalosaurus is noted for having a skull that grew extremely thick on top,‭ ‬perhaps as‭ ‬a form of display or as something used in head pushing contests with rivals.
       Criocephalosaurus was originally named as Criocephalus in‭ ‬1928‭ ‬by Robert Broom,‭ ‬however this name was later realised to have already been used to name a beetle,‭ ‬so the‭ ‬name was changed to Criocephalosaurus in‭ ‬2002‭ ‬to avoid confusion.
