Pair of Fossil Shark (Otodus) Vertebrae - Morocco

This is a small cluster of fossilized shark vertebra which would have come from the extinct, giant mackerel shark, Otodus obliquus. They are Paleocene/Eocene in age, approximately 54 million years old and comes from the phosphate deposits in the Oulad Abdoun Basin of Morocco. The entire matrix is 3.3x2.9" with the largest vertebrae being 1.6" wide. One of the vertebrae has been reattached to the rock, hence the reduced price.

The fossils of Otodus indicate that it was a very large, predatory shark. Based on the size of the largest known teeth and vertebrae Otodus may have reached a maximum size of nearly 40 feet in length. Otodus likely preyed upon marine mammals, large bony fish, and other sharks. 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.
