New Data on Enosuchid Anthracosauromorphs (Amphibia) of the Middle–Late Permian of European Russia: Part 1. Morphology of Enosuchus breviceps Konzhukova, 1955

Resumo

Cranial morphology of the type species of the genus Enosuchus, E. breviceps Konzhukova, 1955, is reexamined in detail based on the holotype and previously undescribed specimens from the type locality (Isheevo; Tatarstan, Russia; uppermost Urzhumian). E. breviceps is distinguished from known anthracosauromorphs by the intense osteogenesis of the dermal and endocranial bones, well developed surface ornamentation, the absence of the intertemporal, expanded interorbital region, and very massive quadrate.
