In our paleo-zoological collection, we have some exciting additions. Please welcome the new heroes: Anthracotherium, Inostrancevia, Cryptoclidus, and Stegouros!

The endearing face of Anthracotherium suggests a distant relative of the hippopotamus. And it's entirely justified - anthracotherium, or the "coal beast," is one of the leading candidates for the title of the "great-grandfather" of the hippopotamus.

Inostrancevia was the most formidable predator of the Permian period. Thousands of parareptiles and other therapsids fell victim to the knife-like teeth of this beastly reptile.

As for Cryptoclidus, it's a typical plesiosaur. However, this in no way diminishes its significance - after all, creatures like this were once among the primary inhabitants of ancient marine Europe.

Finally, Stegouros is a lesser-known but incredibly fascinating dinosaur. It uniquely combines features of stegosaurus and ankylosaurus, and its remarkable tail weapon - the macuahuitl - has no parallels among any other dinosaurs!

You can examine models of their skin, muscles, and skeletons, as well as read detailed information about these animals themselves, their discovery, habitat, family, neighbors, fields of vision, and interesting facts, all available in the "premium" package.
