These are gorgeous teeth from a large Moroccan Sand Tiger shark. These teeth were originally described as Odontaspis robusta (Arambourg 1952), but now are argued to belong to Carcharias hopei. Either way, they are extra large, well preserved, complete (including side cusps) and beautiful. The anterior teeth exhibit straight crowns with a very pronounced root development on the display side, and well developed side cusps. The lateral teeth exhibit a very nicely curved, board crown. Eocene age - approx. 55 million years old. Note - These are the largest Carcharias that that I have seen. Exceptional collector's teeth!
