Mesozoic frogs are rarely found, and this specimen, reported by Kellner and Campos (1988), has not yet been described.
Its presence within the Araripe Basin indicates that palaeoenvironmental conditions did, as proposed, include lacustrine habitats.
The frog illustrated above is about 20mm long
Note that this specimen is recorded from what was previously termed the 'Crato Member'. Now that the Crato Member has been re-classified by Martill (1993) as the Crato Formation, this example does not strictly apply to being part of the Santana Formation. It is, however, representative of the diversity of fossils from this region.
