The lizard (Reptilia, Squamata) assemblage from the Paleocene of Montchenot (Paris Basin, MP6)

Here we describe the lizard fauna from locality of Montchenot (Paris Basin, late Paleocene, MP6). This material can be allocated to five major clades: Scincoidea, Lacertoidea (?Lacertidae), Amphisbaenia, Anguimorpha (?Anguidae and Shinisauridae). The assemblage Monchenot is dominated by small specimens appears as highly sorted. Predation could produce such biased assemblages. composition rather similar those Cernay-lès-Reims Rivecourt, two coeval localities (MP6) in Paris Basin. However, these faunas sharply contrast (in diversity composition) with found early Eocene same area Basin Belgian Basin). These differences highlight impact Paleocene/Eocene transition on Europe.
