Eocene Tiger Shark
Galeocerdo eaglesomei (White)

Age - Eocene  Commonality - Uncommon

Galeocerdo eaglesomei is restricted to the Eocene and has similar characteristics to the commonly found Miocene tiger Galeocerdo aduncus.  These teeth have broad compressed crowns, the mesial side of the crown has a slight curve with medium serrations. Unlike G. aduncus the distal side of the tooth does not possess the distinct notch and very coarse serrations. The root lobes are rounded, and a shallow but distinct nutrient grove is present. When viewed from the lingual side the basil margin of the root dips approximately halfway down the crown. These teeth average between 1/2 to 3/4's of an inch and may reach upwards of 1 inch.

The serrations on the distal side are coarser than the mesial side, but
lacks the notch found on the more common species of tiger
Galeocerdo aduncus.

A very rare symphyseal Galeocerdo eaglesomei.

Author's note: Attributing this specimen to the species eaglesomei
 is based on the fact that this is an Eocene tooth.
