P. cf. bouchardi skull

The type species, S. heberti, was originally named "Steneosaurus" heberti by Morel de Glasville in 1876 from a complete skull and mandible (MNHN.F 1890-13) found in the Callovian aged Marnes de Dives near Villers-sur-mer in the Calvados department of Normandy, France.[2] [3] [4] Steneosaurus depressus is a junior synonym. Another species referred to the genus, Proexochokefalos cf. bouchardi is known from remains from the Calcaire de Caen, France, and Reuchenette Formation, Switzerland.[1]
