New anuran material from Deseadan beds of Scarritt Pocket, Chubut Province, and the supposed presence of palearctic bufonids in the Oligocene of Patagonia

In 1949 Schaeffer described several anuran taxa based on remains from Deseadan beds of the western part of the meseta Canquel in central Patagonia. Among those taxa is the extinct neobatrachian Neoprocoela edentata Schaeffer, the evolutionary relationships of which are still controversial. It was su...
