Quick Plesiosaur Facts

What they were

Marine reptiles that "flew" through the water using four large flippers. Despite how they're often portrayed, plesiosaurs were not dinosaurs.

Those famous necks

The Moroccan plesiosaurs belong to the elasmosaurs, a group known for extremely long necks, some built from more than 70 vertebrae.

What they ate

Fish, squid, and other small prey, which they snared with long, interlocking teeth that worked like a trap.

When they lived

Plesiosaurs lived throughout the age of dinosaurs and disappeared in the same mass extinction 66 million years ago.

Where Our Plesiosaur Teeth Come From

The plesiosaur teeth in this collection come from the phosphate deposits of the Oulad Abdoun Basin near Khouribga, Morocco, roughly 66 to 72 million years old. These deposits preserve an extraordinary record of the last Cretaceous seas, and the plesiosaur teeth found there are often attributed to the elasmosaur Zarafasaurus.

How to Identify a Plesiosaur Tooth

Plesiosaur teeth are long, slender, and gently curved, with a round cross-section and fine vertical ridges running down the enamel. They have no serrations or cutting edges. That sets them apart from mosasaur teeth, which are stouter and usually show two cutting edges, and from the shark teeth found in the same deposits.

Honest Condition Disclosure

Plesiosaur teeth are thin and fragile, so tips and roots are often broken, and restored or filled tips are common on the market. Some teeth are also set into matrix they were not found in. With more than 13 years of fossil identification experience behind every listing, we state plainly whether a tooth is natural, repaired, or restored. Every fossil we sell is backed by our authenticity guarantee and a 30-day return policy.
