Prominatherium is a genus of primitive ungulate that belonged to the Anthracotheriidae family. It lived during the Eocene epoch of Europe and was probably bound to aquatic habitats, like swamps and shores of rivers and lakes. They probably had a semi-aquatic lifestyle and fed on aquatic vegetation and roots. In life, it would have resembled a small hippopotamus-like animal with a narrow skull and pig-like features.
Prominatherium dalmatinum is the only species within its genus and fossils have been found in Croatia and Italy. It was a fairly small sized anthracothere, growing up to about 1 m in length and weighted about 150 kg. The species is poorly known and only some scattered parts of its skeleton have been unearthed so far.
