description Estemmenosuchus mirabilis Overview

Estemmenosuchus mirabilis is a large dinocephalian therapsid from the Middle Permian of what is now Russia. It is recognized by massive, outward-projecting bony structures on the skull, including prominent growths above and beside the head. As an early synapsid rather than a dinosaur, it helps document the anatomical diversity of terrestrial vertebrates before the later radiation of more derived therapsids.
