Bufonid toads from the late Oligocene beds of Salla, Bolivia

Isolated fragmentary anuran remains from several fossil-bearing levels of the continental succession exposed in the Salla-Luribay basin, Eastern Cordillera, are described herein. The anuran material consists of poorly preserved postcranial bones that are referable to toads of the nearly cosmopolitan...

The anuran material consists of poorly preserved postcranial bones that are referable to toads of the nearly cosmopolitan genus Bufo, now widely distributed in South America.
