Hemipristis curvatus

Synonyms: Hemipristis wyattdurhami

The earliest Snaggletooth sharks, their fossils come from (at least) Africa, South America & North America. In most fossil localities (including Morrocco, which my 3 below came from) their fossils seem to be rare. It seems Snaggletooths were just stepping onto the scene in the Eocene, as intense competition/niche regulation with other marine predators such as the still very dominant lamniform sharks ( including the infamous Otodus obliquus), other medium to large carcharhiniform sharks, and large predatory archaeocete whales likely kept their size and abundance in check.

Their teeth are very similar to H. serra's teeth, except of course they do not grow as large and do not bear as many serrations. As far as I can tell, H. curvatus teeth did not exceed 1 inch in length.
