These are authentic fossil shark teeth from the Eocene 54 Million Years ago. They are from the species Otodus obliquus, a type of giant mackerel shark. Nearly all of these teeth range from 1 1/2″ to 2″ long though some maybe slightly larger and some slightly smaller.
The photos are representative of the teeth you will receive but the exact ones are not pictured.
Otodus is an extinct mackerel (Lamniformes) shark that lived during the Eocene, approximately 54 million years ago. This is the same family of sharks that includes the Great White and the largest shark ever known, the Megalodon.
