Xiphodontidae is an extinct familyofherbivorous 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] Paraxiphodon suggests that they survived into the Lower Oligocene, at least.[2]
The molar teeth of xiphodontids are brachydont (low crowned) and selenodont.[3]
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).[4][5] A 2020 study suggested them to be related to ruminants, as well as other Europe-endemic artiodactyls like Cainotheriidae and Anoplotheriidae.[6]
