This is a relatively uncommon fossil shark with delicate, very attractive teeth. Little is known about it's ancestors; it became extinct in the Late Eocene, about 35 million years ago leaving no living descendants. The front teeth are spear-like and the lateral teeth possess large separate lateral cusps giving them an exotic appearance.
