Summary:Coprolites of marine reptiles were first described in the early nineteenth century. During the 1980s, coprolites were found in the Bearpaw Formation (Upper Cretaceous; upper Campanian) in southern Saskatchewan. Beechybromus wellschi igen. et isp. nov. is a coprolite that is elongate and sub-cylindrical with rounded cross section and is composed of up to 12 discoidal segments; the posterior termination is rounded, and the anterior consists of a triangular apex. It most probably pertains to a mosasaur. A partial specimen from Kansas may pertain to this ichnogenus. Segmented coprolites are typical of mosasaurs.
