Mosasaurus Tooth | Cretaceous Period

The Mosasaurus was a large, predatory marine reptile that lived during the Late Cretaceous Period, about 101 to 66 Million Years Ago. It was part of the Mosasaur family, a group of powerful, serpentine predators that dominated the seas in the final era of the dinosaurs. Despite its superficial resemblance to dinosaurs, Mosasaurus was more closely related to modern snakes and monitor lizards. These reptiles had streamlined bodies, paddle-like limbs, and long, muscular tails, which made them well-adapted for swimming in ocean environments.

Growing up to 17 meters (about 56 feet) in length, Mosasaurus was one of the largest mosasaurs, and it was likely an apex predator. Its long, robust jaws were filled with conical, sharp teeth, perfect for seizing prey such as fish, marine reptiles, ammonites, and even smaller mosasaurs. The positioning of its eyes high on its skull gave it keen vision for hunting in the water, while its nostrils were set back, allowing it to breathe while partially submerged, similar to modern crocodiles.

Mosasaurus’ success as a marine predator is evidenced by its widespread fossil record, with remains found on multiple continents, indicating it inhabited a variety of oceanic environments. Unlike earlier marine reptiles, such as ichthyosaurs and plesiosaurs, which had gone extinct by the time mosasaurs evolved, these reptiles filled the top ecological niches in Cretaceous seas. Like many other species, Mosasaurus went extinct during the mass extinction event at the end of the Cretaceous, when a combination of climatic changes and the impact of an asteroid drastically altered Earth’s ecosystems.

Ancient Artifacts guarantees the Authenticity of items sold through a three layer system of protection: 

1. Ancient Artifacts exclusively sources artifacts from trusted and reputable antique distributors, many of whom have been selling Artifacts for decades.  
2. Next, the Artifact is inspected by an expert team member, who is professionally trained in counterfeit detection After the artifact passes inspection, the Certificate of Authenticity is signed and the Artifact is packaged. 
3. Finally, Ancient Artifacts gives an additional layer of protection by promising a full refund with no questions asked, in the extremely unlikely event that a counterfeit slips through our vetting process.

Your Mosasaurus tooth will look very similar to the one shown in the photos. There will always be some variety, given our items are unique historical pieces. The display case included is openable so that you may easily handle and closely observe the artifact. If for whatever reason you get anything that does not fit this description you are entitled to your money back! 

Like many of our fossil items, these teeth come from the Kem Kem beds of Morocco, a Geological formation known for its abundant fossils. The region was once a lush, river-dominated delta, characterized by sprawling waterways, floodplains, and forests. This unique environment served as a crossroads between freshwater and terrestrial ecosystems, creating a thriving habitat for a wide variety of species.

Fossils from the Kem Kem Beds are remarkably common and widely available due to a combination of geological, environmental, and socioeconomic factors. This unique fossil hotspot in southeastern Morocco offers a rich supply of specimens, and the region's historical approach to fossil collection and trade has made these fossils accessible to researchers, collectors, and enthusiasts worldwide. The sheer abundance of these fossils permits widespread private collection for a relatively low cost.
