At the time when the tyrannosaurs ruled the continents, gigantic predatory lizards roamed the seas. These were the mosasaurs.

Strangely, not many people have ever heard of them. That is why we have decided to present a few of the specimens from our mosasaur collection, one of the biggest in the world. These are now on display in a cosy, well-lit gallery next to our iguanodon exhibit in the basement.

Here, you can admire a 12.5-metre-long Belgian specimen, Hainosaurus bernardi, compare the anatomy of the mosasaurs with that of reptiles and other modern-day animals, understand the mechanics of how they swam, and much more.
