1.67" Fossil Early Ungulate (Cainotherium) Jaw - Quercy, France

This is a 1.67" wide jaw section (mandible) from an Oligocene ungulate, Cainotherium. The jaw contains 5 well-preserved teeth.

This genus of prehistoric ungulates was roughly the size of modern rabbits and may have eaten in the same fashion as a rabbit would, despite the presence of canine-like teeth. In addition to eating like a rabbit, skeletal evidence suggests that Cainotherium may have hopped in a similar fasshion to rabbits. Cainotherium grazed throughout Europe from the Eocene into the Miocene epoch (~56-20 m.y.a). These herbivores were in the same suborder as modern Camelids and Oreodonts, but were smaller in stature than those species.

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 from the middle 19th century until the early 20th century in a series of sites which are no longer accessible. These fossils subsequently became dispersed over several research institutions, while unfortunately often losing the temporal and geographical information in the process. This material is part of an old collection we acquired and 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.
