A fossil ceratophryid anuran from the Late Miocene of west-central Argentina
Deutsche Gesellschaft für Herpetologie und Terrarienkunde e.V.
Remains of a Miocene anuran attributed to Ceratophryidae, the clade of South American horned frogs, are described. This material is especially relevant because few pre-Pliocene fossils have been attributed to Ceratophryidae and, in most cases, these attributions are controversial. The fragmentary Miocene fossil described here possesses all the phenotypic synapomorphies proposed for Ceratophryidae that can be evaluated in the preserved bones. The remains also share some features with different living ceratophryid species. Additionally, they possesses a series of characters not observed in other Ceratophryidae. The exclusive combination of character states observed in the fossil material indicates that it represents a new species. However, the species cannot be named until relationships among ceratophryid frogs are resolved and the position of the fossil within the clade can be determined; it is possible that it might be nested in an extant genus.
