Cetotherium

The modest sized Cetotherium was a primitive baleen whale that lived during the middle to late Miocene epoch (15 MYA) of the Neogene Period. This whale genus is known from several individual species, perhaps as many as 10, that have been found in the USA, across Europe and Russia. When compared with their modern counter parts (e.g. humpback whales), their sizes were much smaller 2-4 metres.
