Discovery of a primate more than 11 million years old
Date:4/21/2010

Catalan researchers have discovered in the rubbish dump of Can Mata in the Valls-Peneds basin (Catalonia) a new species of Pliopithecus primate, considered an extinct family of primitive Catarrhini primates (or "Old World monkeys"). The fragments of jaw and molars found in this large site demonstrate that Pliopithecus canmatensis belongs to this group, which includes the first Catarrhini that dispersed from Africa to Eurasia.

Named Pliopithecus canmatensis, in honour of the place they were discovered in Catalonia, the new fossil species sheds light on the evolution of the superfamily of the Pliopithecoidea, primates that include various genera of basal Catarrhini, a group that diverged before the separation of the two current superfamilies of the group: the cercopithecoids (Old World monkeys) and the hominoids (anthromorphs and humans); and which prospered in Eurasia during the Early and Late Miocene (between 23.5 and 5.3 million years ago).

"Based on the anatomical, palaeobiographical and biostratigraphic information available, the most probable evolutionary scenario for this group is that the Pliopithecoidea were the first Catarrhini to disperse from Africa to Eurasia, where they experienced an evolutionary radiation in a continent initially deserted of other anthropoids (apes)", David Alba, main author of the study and researcher at the Catalan Institute for Palaeontology at the Autonomous University of Barcelona (UAB), explains to SINC.

The analysis of the dental pieces and the fragments of jaw discovered on the Catalan site has been published in the American Journal of Physical Anthropology.

According to the conclusions of the study, the new species belongs to the subfamily of the pliopithecines, which could have originated from an ancestor called the dionsisopithecine in Asia, from where they would have dispersed into Europe at the end of the Early Miocene (some 15 million year
