Information retrieved from Wikipedia - see citation at the bottom. 

Otodus is an extinct genus of mackerel shark which lived from the Paleocene to the Miocene epoch. The name Otodus comes from Ancient Greek ὠτ (ōt, meaning "ear") and ὀδούς (odoús, meaning "tooth") – thus, "ear-shaped tooth".  

Size estimation

The fossils of Otodus indicate that it was a very large macro-predatory shark. The largest known teeth measure about 104 millimeters (4.1 in) in height. The vertebral centrum of this shark are over 12.7 cm (5 inch) wide. Scientists suggest that this shark at least reached 9.1 meters (30 ft) in total length (TL), with a maximum length of 12.2 meters (40 ft).


Otodus had a worldwide distribution, as fossils have been excavated from Africa, Asia, Europe, and North America.


Otodus likely preyed upon large bony fish, other sharks, and from the Eocene until the genus' extinct during the Miocene, marine mammals. It was among the top predators of its time.


Scientists determined that Otodus evolved into the genus Carcharocles, given substantial fossil evidence in the form of transitional teeth. Some teeth have been excavated from the sediments of the Potomac River in Maryland, USA, Ypres clay in Belgium, and western Kazakhstan, which are morphologically very similar to Otodus teeth but with lightly serrated cusplets and a serrated cutting edge. These transitional fossils suggest a worldwide evolutionary event, and support the theory that Otodus eventually evolved into Otodus aksuaticus and thus initiated the Carcharocles lineage.
