Whatcheeriidae is an extinct family of tetrapods which lived in the Mississippian sub-period, a subdivision of the Carboniferous period. It contains the genera Pederpes, Whatcheeria, and possibly Ossinodus. Fossils of a possible whatcheeriid have been found from the Red Hill locality of Pennsylvania. If these remains are from a whatcheeriid, they extend the range of the family into the Late Devonian and suggest that advanced tetrapods may have lived alongside primitive tetrapod ancestors like Hynerpeton and Densignathus.[1] They also imply that a very long ghost lineage of whatcheeriids lived through Romer's gap, a period during the Early Carboniferous conspicuously lacking in tetrapod remains.[2]
Classification
Currently, using modern cladistic taxonomy, Whatcheeriidae is not placed in Amphibia or any other class but simply as its own family within stem-group tetrapods. The analysis below was conducted by Swartz in 2012, showing the relationship of whatcheeriids with other stem-tetrapods.[3]
