Otodus auriculatus - NC Red Site    

This catalog contains gorgeous copper red colored teeth from O. auriculatus, the first Giant White shark.O. auriculatus teeth are noted for their triangular crown and very large side cusps which are heavily serrated. These Auriculatus teeth are from the Eocene Castle Hayne Fm. (Bartonian age  38-45 million years ago). They are found in the northern part of the state known for the rare copper red colored teeth. These copper red  colored teeth are quite rare and very difficult to find which adds to their rarity. All teeth listed are near museum quality or better. Absolutely NO restoration or repair in this group! Try finding one of these species with the rare copper red colors! 

The late Eocene Auriculatus is the final stage of Auriculatus development with large serrated side cusps and crowns completely serrated with large serrations.

This site has the extremely rare occurrence of Auricualtion transition sequence from the non-serrate Otodus to the serrated Auriculatus is found - especially in the US. Absolutely NO restoration or repair in this group! Try finding one of these species with the rare copper red colors!

Otodus obliquus - is the ancestor to O. auriculatus (and C. megalodon), and exhibits a rather narrow & square root with well pronounced root lobes. The crown is sharp blade with no serrations.

Otodus aksuaticus - is a transitional form between O. obliquus to O. auriculatus, and exhibits well pronounced medium to light serrations covering the lower 3/4 to 1/2 of the crown.

Otodus auriculatus - is the ancestor to C. megalodon, and exhibits well pronounced medium to heavy serrations covering the crown and irregular side cusp serrations. The earliest form look very much like a serrated Otodus tooth
