Real Fossil Mosasaur Tooth - 1" Size

 
 
These are real fossil Mosasaur teeth from the Late Cretaceous (~70 Million Years) phosphate deposits near Khourigba, Morocco. Small Mosasaur teeth are quite common in these deposits and are collected by locals as a byproduct of the massive phosphate mining operations in the area.

The photos of representative of the fossil tooth you will receive and the packaging that it comes in. The teeth average a little over an inch in length. These aren't perfect teeth, many will have some dings, maybe a missing tip of a repaired crack. Each fossil Mosasaur tooth comes nicely packaged along with an information card and authenticity guarantee. For larger, higher quality teeth, please check out our individually photographed specimens.

Mosasaurs

Artists reconstruction of the mosasaur Prognathodon saturator.
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.





Mosasaurs probably lurked for an ambush, rather than hunt, possibly using their powerful tail flukes for extra thrust to dart out and swallow unsuspecting prey. Non-reflective, keeled scales may have been a great advantage to the Mosasaur sneak-
attack.

Mosasaurs breathed air and gave birth to live young. The bronchi leading to the lungs run parallel to each other instead of splitting apart from one another as in monitors and other terrestrial reptiles. They were well-adapted to living in the warm, shallow, epicontinental seas of the period.

Although Mosasaurs diversified and proliferated at a spectacular rate, their specialization is considered the source of their demise when marine systems collapsed at the end of the Cretaceous.
