A new Late Maastrichtian vertebrate locality in the French Petites-Pyrenees

A new Late Maastrichtian locality from the Petites-Pyrenees has yielded an important vertebrate fauna. It includes Chondrichthyes (undetermined neosel achian), Osteichthyes (Lepisosteidae, Phyllodontinae, Sparidae?), Chelonia (Pleurodira), Crocodylia, and Dinosauria (Theropoda, Hadrosauridae, Nodosau ridae). It is the first mention of a Cretaceous phyllodontine and the First mention of an ankylosaur in the French Late Maastrichtian. Lestailiats is the richest Late Maastrichtian locality in southern France because of dhe o ccurrence of both a microfauna and macroverlebrates. It offers new perspect ives for the knowledge of the diversity and the evolution of the European v ertebrate assemblages in the Latest Cretaceous. (C) Academie des sciences/E lsevier, Paris.).
