Out of stock

very rare, Otodus auriculatus tooth from the copper-red site of No. Carolina. The crown has coarse serrations. The side cusps are typical of the Otodus obliquus. Complete root. Early Eocene - Ypresian age. very rare collector's tooth. Very few Otodus auriculatus teeth (early form) found at this site!

Note - Adding 9 early NC red site early Rics, transition teeth, and later Rics in June 2020.  Link to NC Auriculatus teeth


This catalog contains very rare, early Eocene teeth representing the transition from Otodus oliquus to O. auriculatus, the first Giant White shark. All of these Otodus teeth may be transitionals.These transition teeth are incredibly rare and almost never seen in the US.  All of these teeth were found together. This is a extremely rare occurrence where the sequence of transition 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.
