Abstract

We present results of a comparative morphological analysis of the postcranial osteoderm cover of the East European pareiasaurs Scutosaurus karpinskii (Amalitzky), S. tuberculatus (Amalitzky), S. itilensis Ivachnenko et Lebedev, Deltavjatia rossica (Hartmann-Weinberg), Proelginia permiana Hartmann-Weinberg, Obirkovia gladiator Bulanov et Jashina, and Senectosaurus karamzini Boyarinova et Golubev. Postcranial osteoderms provide important diagnostic characters, enabling identification of genus- and species-level taxa. All known pareiasaur genera fundamentally differ from each other in the structure of the osteoderm cover. The validity of the genus Proelginia is confirmed. Diagnoses of the East European pareiasaur genera and species are supplemented by characteristic features of the osteoderm cover.
