Species
Deuterosaurus biarmicus
Deuterosaurus biarmicusDeuterosaurus biarmicus roamed river floodplains across what is now European Russia during the Middle Permian, long before the rise of dinosaurs. As an early dinocephalian, it possessed a heavily built skull featuring thickened cranial bones likely used in head-butting or flank-shoving contests between rivals. Its distinct dentition included stout incisors, prominent canine tusks, and broad crushing cheek teeth suited for fibrous vegetation, roots, and occasional opportunistic meat.
