Isurus praecursor                          

This catalog contains exceptional teeth from Isurus praecursor, the earliest Mako shark. I. praecursor teeth are noted for a narrow non-serrate crown. The Togo site Isurusare exceptionally preserved and colorful. I do not see these top quality, early Mako teeth too often!

The Togo teeth are well preserved with good color, and they represent a geologic age that is different from other localities. They are Lutetian age (45 MYA), lower middle Eocene. So, this deposit is older than the Moroccan early Eocene & Cretaceous phosphate teeth and younger than the Moroccan late Eocene Dhakla fossils.

Togo is a small West African national situated between Ghana and Benin. If you still have no idea where Togo resides, it is to the west of Nigeria. Togo’s leading industry is phosphate mining and phosphate ore is one of their main exports. And where there is phosphate, good marine fossils are often found.
