Xenokeryx is a genus of palaeomerycid artiodactyl mammal that lived in western Europe during the Miocene. Xenokeryx is noted to have a bizarre T-shaped horn rising up from the back of the skull. This horn is the inspiration of the type species name X. amidalae, which is a reference to the character of Queen Amidala from Star Wars: The Phantom Menace who wore an elaborate head dress.
