==Taxonomy== thumb|left|Skull of Merycoidodon culbertsoni Most researchers in paleobiology and paleontology now use the antecedent genus Merycoidodon to refer to this Oligocene epoch oreodont, even though it was once widely known by the younger synonym of Oreodon. Taxonomically speaking, Merycoidodon belongs to the family Merycoidodontidae (once known as "Oreodontidae"), a group of artiodactyls related to camels that were endemic to North America. Its ancestors date back to the Eocene and its last descendants are known from the end of the Miocene, so that oreodonts, broadly speaking, lived throughout most of the Paleogene.
