.27" Eocene Fossil Primate (Pseudoloris) Jaw Section - France

Pseudoloris is an extinct genus of small primates, similar to modern tarsiers. They are some of the earliest members of the family Omomyidae, which includes largely extinct lemurs, tarsiers, and other small primates.

Like modern tarsiers, Pseudoloris had large eyes and were likely nocturnal, feeding on insects or fruit.

The Quercy Phosphorites Formation in France is world famous for its Eocene to Miocene faunas, especially those from the upper Eocene to lower Oligocene. The latter particularly helped to understand the ‘Grande Coupure’, a dramatic faunal turnover event that occurred in Europe during the Eocene-Oligocene transition. Fossils from the Quercy Phosphorites were excavated during the mid-19th century until the early 20th century from a series of sites that are no longer accessible. These fossils have subsequently dispersed between several research institutions, unfortunately losing some temporal and geographical information in the process. This material is part of an old collection we acquired that presumably was collected along with this material in the 19th or early 20th century. A recently published paper on the mammals of the Quercy Phosphorites can be found below.
