Mosasauroid (Squamata) discovery in the Late Cretaceous (Early Campanian) continental deposits of Villeveyrac–L’Olivet, southern France

New mosasauroid material from the Villeveyrac-L’Olivet mine (Hérault, southern France) is described. This historical and fossiliferous bauxite mine has yielded from the same stratigraphical level (Early Campanian) diverse continental vertebrates, including fishes (Lepisosteidae and Phyllodontidae), amphibians (Albanerpetondidae and the oldest representative of the Palaeobatrachidae), turtles (Solemydidae and Bothremydidae), squamates (Mosasauroidea), crocodilians (Eusuchia), dinosaurs (Rhabdodontidae, Nodosauridae and Dromaeosauridae), and a possible pterosaur. The mosasauroid specimens represent different individuals of a single taxon, belonging to a large plesiopedal tethysaurine-like form (about 3 meters long). This discovery adds to previous reports of plesiomorphic freshwater mosasauroids in the Late Cretaceous dinosaur-bearing sites of the European archipelago.
