( FIG. 2H ) Referred specimen —SC2013.38.7, incomplete anterior tooth. Remarks —This specimen differs from Nebrius sp. cf. Neb. thielensi (see above) in having only a single pair of large lateral cusplets, and the labial crown foot is distinctively bifid but not drawn out into an elongate basal protuberance. SC2013.38.7 is similar to the anterior teeth of Cretaceous Plicatoscyllium Case and Cappetta, 1997 , but there is no indication of labial crown ornamentation. The single pair of lateral cusplets also distinguishes SC2013.38.7 from the various early Paleogene species of Ginglymostoma (Noubhani and Cappetta 1997) . In terms of gross morphology, SC2013.38.7 is similar to Protoginglymostoma ypresiensis ( Casier, 1946 ) from the early to middle Eocene of Belgium and Morocco ( Casier 1946 , Herman 1977 , Tabuce et al. 2005), but the poor condition of the only available tooth makes a more precise identification difficult.
