Resumen:
Fossil
anuran remains from an outcropping of Oligocene sediments in central Patagonia have been attributed to the extant genus Eupsophus based on their putative
similarity to the skeleton of living members of this genus. These remains would
represent the only and oldest evidence of the existence not only of Eupsophus, but also of any cycloramphid
anuran in Patagonia during the past. Given the
scarcity of the anuran
fossil record, these fossils have been long considered as significant evidence
in the discussion of the evolutionary history of the South American
batrachofauna. However, re-examination of these specimens reveals that some
skeletal structures were misinterpreted and that these anurans clearly differ
from living Eupsophus. Although
osteological synapomorphies of this genus are still unknown, there is no
evidence to link these
fossil remains with the presence of Eupsophus
in the Oligocene batrachofauna of Patagonia
