Primate diversity in the early Miocene Pinturas Formation, southern Patagonia, Argentina.

We report ten new dental specimens of primates from the early Miocene Pinturas Formation, Patagonia, Argentina. The new material includes: a left lower canine and a left upper canine whose affinities remain to be determined; a mandibular fragment preserving part of the symphysis; and right p3-4, practically indistinguishable from Soriacebus adrianae; and a lower molar, probably m2, attributable to S. ameghinorum.
