Authentic Fossil Mosasaur Tooth Necklace

This is a necklace featuring an authentic fossil Mosasaur tooth. The Mosasaur tooth is Upper Cretaceous in age or approximately 70 million years old. TThese teeth are found near Khouribga, Morocco during phosphate mining operations and are Upper Cretaceous in age. Most of the teeth are from the species Eremiasaurus heterodontus and they range from 1 1/4 to 1 3/4 inch in length. The necklace cord itself is 19 inches long.

are a family of enormous, marine reptiles that truly dominated the seas 90 million years ago. They ruled during the last 20-25 million years of the Cretaceous period. With the extinction of the ichthyosaurs and decline of plesiosaurs, mosasaurs diversified to become prolific, apex predators in nearly every habitat of the oceanic world.

Larger mosasaurs were the great leviathans of their time, extending 10–15 m, or 33–49 ft long. Hainosaurus holds the record for longest mosasaur, at a seemingly impossible, 57 ft. The smaller genera were still an impressive, 10–20 ft long. Mosasaurs probably evolved from semi-aquatic, scaled reptiles which were more similar in appearance to modern-day monitor lizards. They had double-hinged jaws and flexible skulls (much like that of a snake), which enabled them to gulp down their prey almost whole.

The gruesome, unchewed contents of fossilized mosasaur guts have revealed a varied diet of sea birds, ammonites, smaller marine lizards, possibly shark, and even other mosasaurs. Ammonites were especially crunchy mosasaur treats. They were abundant in the Cretaceous sea, and some Mosasaur had specialized teeth for the job.
