Xiphodontidae
Xiphodontidae is an extinct family of even-toed ungulates (order Artiodactyla), endemic to Europe during the Eocene 40.4—33.9 million years ago, existing for about 7.5 million years.[1] They were, most likely, all terrestrial herbivores. Paraxiphodon suggests that they survived into the Lower Oligocene, at least.[2]
