A new escuerzo (Anura, Leptodactylidae) from the Ensenadan (Lower- Middle Pleistocene) of Buenos Aires Province (Argentina), with notes on the classification of the genus Ceratophrys

Abstract

The new species; Ceratophrys rusconii is here described. It is distinguishable from other members of this genus mainly by the laterally expanded and anteroposteriorly compressed post-orbital gaps. This fossil species is nearly related to living C ornata and C cranwelli Additionally, the earliest record for the subfamily Ceratophryinae is recorded from the Middle-Upper Oligocène of Patagonia
