Overview

A very rare, early Otodus mugodzharicus upper jaw, lateral tooth from western Kazakhstan. A transition tooth leading to C. auriculatus (see detailed discussion below). The bourlette is large and complete. Exhibits very fine serrations along the lower 2/3 of the crown and weakly serrated side cusps with very irregular serrations. These teeth exhibit very good color, gloss, and preservation. A rare, early Eocene Auriculatus transition tooth. A very challenging tooth to find when building a Megalodon evolutionary set! No repair. Authenticity guaranteed.

This catalog contains excellent teeth from an extinct Otodontid shark - Carcharocles auriculatus, a precursor to the Megalodon. The early Carcharocles auriculatus is fully serrated with very large serrations and highly irregular cusps serrations.

The Evolutionary Path to Megalodon - transition from the non-serrate Otodus obliquus to the fully serrated Auricuation tooth - The Kazakhstan early Eocene sediments are one of the few places in the world where the transition to the fully serrated Auriculatus tooth can be observed and collected.  The  transition teeth representing the progression from Otodus obliquus to the Auriculatus are as follows.

Carcharocles mugodzharicus or Otodus mugodzharicus - has very fine serrations covering lower 2/3s of the crown (sometimes the serrations can be the wavy "Escheri-like" serrations) and little to no side cusp serrations. 

Carcharocles aksuaticus or Otodus aksuaticus - a semi-serrated or finely serrated tooth that can have moderate sized serrations at the base of the crown. The side cusps will have few serrations.

Kazakhstan site - These teeth are very rare, early Eocene (Ypresian) in age (approx. 55 mya) from Kzil-Orda region in western Kazakhstan (new location). Note - this location has been collected for ~3 summers and it is now exhausted. This is the last of the material from this site that made it to US. Some incredibly rare teeth are posted.
