Kazakhstan - Isurus praecursor

This catalog contains teeth from an extinct precursor Mako shark - Isurus precursor. The Russians refer to this shark as Cosmopolitodus americanus  C. americanus teeth have a triangular straight crown with no serrations or side cusps. The preservation of these middle Eocene teeth is outstanding showing exquisite detail. These teeth have been hand selected from a large group to ensure excellent condition, great color, and large size. These are exceptional fossil shark teeth from the very first Mako shark to evolve (aka Isurus praecursor) and are highly desirable for collectors. These are beautiful flawless or near flawless teeth! Another excellent selection ever from my old inventory!

Note - all teeth sizes are slant height unless otherwise noted. Click on photos to enlarge. Catalog updated on December 2, 2007.
