Giant Otodus Shark Vertebrae - 4 Inches Wide!

This is the large vertebrae of Otodus obliquus that I've ever seen. At 4 inches wide it would equate to a shark close to 40 feet in length. It was collected from the phosphate deposits in the Oulad Abdoun Basin of Morocco. The preparation work is top notch and it displays nicely on a flat surface.

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.
