Pirodus

Pirodus is an extinct genus of caseodontid eugeneodont from the Carboniferous of Russia. The genus includes a single species, P. conicus, which is known only from a single, incomplete fossil of its lower teeth. These teeth were fused together and sat along the midline of the jaw.

Discovery

The holotype specimen of Pirodus was described by researcher Oleg Lebedev in a 2001 paper, and originated from the Shchurovo-Korobcheyevo Formation of Moscow Oblast, Russia.

Description

Pirodus is known from a fragment of a tooth-whorl surrounded by dermal denticles. The tooth-whorl of this taxon consisted of a single fused base with multiple flattened, overlapping crowns protruding from it. The denticles of the taxon are large and conical, and may have been fused to the teeth.
