Anthracotheriidae is a family of extinct, hippopotamus-like artiodactyl ungulates related to both hippopotami and pigs. They thrived in Africa and Eurasia, with a few species ultimately entering North America during the Oligocene, and eventually died out in Europe and Asia during the Miocene, possibly due to a combination of climatic changes and competition with true hippopotami. The youngest genus, Merycopotamus, died out in Africa during the early Pliocene. The family is named after the first genus discovered, Anthracotherium, which means "coal beast," as the first fossils of it were found in Paleogene-aged coal beds in France. hfajhfiudshfas == == == --24. ...

In life, the average anthracothere would have resembled a skinny hippopotamus with a comparatively small, and narrow head.

Recent evidence gained from comparative gene sequencing further suggests that anthracotheres, together with hippos, may be close to the ancestry of the whales. However, the earliest known anthracothere, Elomeryx, appears in the fossil record in the Late Eocene of Europe, well after the archaeocetids had taken up a totally aquatic lifestyle.
