In 2021, scientists identified a new mosasaur species upon the discovery of a Cretaceous-period jaw with unusual teeth in a Moroccan mine. There’s only one problem—the remains may have been ...

The shape of the spine also indicates that the species may have had a dolphin-like dorsal fin, a first for mosasaurs. Since 2010, the Wakayama Prefectural Museum of Natural History and other ...

This 72-million-year-old mosasaur fossil once believed to be a new species, was recently determined in a new study to potentially be a forgery. Scientists are asking for more high-tech CT scans to ...

This specific mosasaur was extremely large - similar in size to a great white shark - and it is thought it had a shark-like dorsal fin, which helped it move quickly and precisely in the water.
