The Quercy Phosphorites Formation in France is renowned for its rich Eocene to Miocene fauna, particularly the Upper Eocene to Lower Oligocene fauna, which has helped in understanding the 'Grande Coupure' event in Europe. This study reassesses and provides an overview of the barely known collections from the Quercy Phosphorites housed in three Belgian institutions, focusing on carnivorous mammals. The fossils are from various stratigraphic intervals in the Quercy area, making these collections of great interest for further systematic and evolutionary studies related to the 'Grande Coupure'.
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 richest of all. 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 19 th century until the early 20 th century in a series of sites and became subsequently dispersed over several research institutions, while often losing the temporal and geographical information in the process. In this contribution, we provide an overview and reassess the taxonomy of these barely known collections housed in three Belgian institutions: the Universite de Liege, KU Leuven, and the Royal Belgian Institute of Natural Sciences. We focus our efforts on the carnivorous mammals (Hyaenodonta and Carnivoramorpha) and assess the stratigraphic intervals covered by each collection. These fossils are derived from upper Eocene (Priabonian), lower Oligocene (Rupelian), and upper Oligocene (Chattian) deposits in the Quercy area. The richness of the three collections (e.g., the presence of numerous postcranial elements in the Liege collection), the presence of types and figured specimens in the Leuven collection, and some identified localities in the RBINS collection make these collections of great interest for further studies on systematics and the evolution of mammals around the 'Grande Coupure'.
