Branisella Boliviana Hoffstetter, 1969

Earliest platyrrhine from the late Oligocene (c. 27 mya) of Bolivia. Four specimens recovered, consisting of molars, premolars, mandible and maxilla. There is an incomplete set of dentition with 3 molars and 3 pre-molars, and presumed dental formula is 2.1.3.3; cusp patterns suggest frugivory. Short face; mandible shallow, suggestive of the parapithecids. Body mass estimate 1 kg. Relationship to later platyrrhines is ambiguous, although the recovered material is reminiscent of cebids like Saimiri or Aotus. Nevertheless, Branisella also has some omomyid features.
