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]
The Xiphodontidae were named by Flower (1883). It was assigned to Artiodactyla by Cope (1889); to Xiphodontoidea by Hooker (1986); and to Tylopoda by Carroll (1988).[3][4]
