The skull is noted for being particularly broad at the back with a short snout, suggesting morphological adaptations for a proportionately high bite for tis size. This is because there would be room for larger … Read more

The skull remains of Kerberosaurus were discovered in a bone bed of … Read more
In Depth Tethysaurus is a primitive (basal) mosasaur that is considered to be related to Russelosaurus from North America and Yaguarasaurus from South America. Like these other two mosasaurs, Tethysaurus has a mixture of both primitive and advanced features that make it a primitive relative to other later mosasaur groups, although not as primitive as … Read more
In Depth Named in 2014, not much can be said about Surameryx because the genus has been named from just a lower left jaw. However, by being recovered from a late Miocene aged deposit, we do know that the presence of Surameryx in South America is a rare example of a mammal with North American … Read more
