Extinct pipoid frogsDavid Cannatella
As discussed under the account of Pipidae, Ford and Cannatella (1993) defined the node-based name Pipidae to be the most recent common ancestor of living pipids (Xenopus, Silurana, Hymenochirus, Pseudhymenochirus, and Pipa) and all of its descendants. Taxa considered to be fossil "pipids" (†Thoraciliacus, †Cordicephalus, †Saltenia, †Shomronella, and †Eoxenopoides) are assigned only to the level of Pipimorpha.
