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.[1]
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 (or root) with multiple flattened, overlapping crowns protruding from it.[1] The denticles of the taxon are large and conical, and may have been fused to the teeth.[2]
