. . . . "Avitabatrachus uliana is the single species in the extinct genus Avitabatrachus, a genus of prehistoric frogs that lived in the Middle Cretaceous. Fossils of A. uliana were found in north-west Patagonia in Argentina. It was properly described in 2000 and was then concluded to be most closely related to Pipidae frogs and hence was included in Pipimorpha."@en . . "Fossil" . . "Avitabatrachus uliana"@en . . . .
