Aletomeryx is an extinct genus of Artiodactyla, of the family Palaeomerycidae, endemic to North America from the early Miocene epoch (Hemingfordian stage) 20.6—16.3 Ma, existing for approximately 4.3 million years.[1]


Aletomeryx was named by Lull (1920). It is the type genus of Aletomerycinae, Aletomerycini. It was assigned to Dromomerycidae by Lull (1920) and Janis and Manning (1998); and to Aletomerycini by Prothero and Liter (2007).[2][3][4]

Fossil distribution[edit]

Fossils have been recovered from the Midway Site in Florida, Saskatchewan, Boron, California, and several sites in Nebraska and Wyoming.
