About Thalassotitan

Thalassotitan was one of the most formidable marine predators of the Late Cretaceous seas. Discovered in the phosphate deposits of Morocco and described in 2022, this giant mosasaur lived around 66 million years ago, just before the mass extinction that ended the age of dinosaurs. Its name—meaning “sea titan”—is fitting: Thalassotitan reached lengths of up to 30 feet and possessed a massive, powerfully built skull unlike that of most other mosasaurs.

What set Thalassotitan apart was its role as a true apex predator. Its broad jaws and robust, banana-shaped teeth were not designed for snatching small, slippery prey, but for crushing and tearing apart large animals. Fossil evidence suggests it preyed on sizable marine reptiles such as plesiosaurs, sea turtles, and other mosasaurs, placing it at the very top of the Late Cretaceous marine food web. In ecosystems already crowded with large predators, Thalassotitan stood out as a specialist hunter of other giants.

It comes from the massive phosphate deposits in the Oulad Abdoun Basin near Khouribga, Morocco. These deposits are mined for phosphate, one of Morocco's biggest exports. The fossils are collected as a byproduct of the mining operations, saving them from certain destruction by the rock crusher.
