Carcharias sp.

Fig. 4C .

Referred specimens.—BCGM 9053 and 9054.

Comments.—BCGM 9053 is a posterior tooth that is undiagnostic and differs little in morphology from teeth in SC.86.62.2 (jaws of C. taurus ). BCGM 9054 is a lateral tooth from a very young individual ( Fig. 4C ) and has a very gracile morphology and large lateral cusplets like C. acutissimus (Agassiz, 1843) and C. gustrowensis (Winkler, 1875) (see Reinecke et al. 2001, 2005). The specimen appears to be closer to C. gustrowensis in its lack of lingual ornamentation (see also Haye et al. 2008), but a larger sample is needed to determine if these teeth represent a species other than C. cuspidatus (see above).
