Description

Hippopotamus antiquus, commonly known as the European Hippopotamus, was a large semi-aquatic mammal that inhabited Europe during the Early to Middle Pleistocene epoch. Significantly larger than the modern common hippopotamus (Hippopotamus amphibius), H. antiquus had an estimated body mass ranging from 3,500 to 4,200 kg. Its skull was more slender and elongated, with higher-positioned eye sockets, and its feet had shorter metapodial bones, suggesting adaptations for a more aquatic lifestyle. Isotope analyses indicate a preference for aquatic vegetation, contrasting with the terrestrial grazing habits of its modern relatives.
