• Paleocene Mammals of the World: Carnivores, Creodonts and Carnivorous Ungulates

Mesonychia ("middle claws") is an extinct taxon of small- to large-sized carnivorous digitigrade ungulates related to the cetartiodactyls. Mesonychids first appeared in the early Paleocene, went into a sharp decline at the end of the Eocene, and died out entirely when the last genus, Mongolestes, became extinct in the early Oligocene.
