Eozygodon is an extinct genus of proboscidean in the family Mammutidae that is based on a single species, E. morotoensis, named in 1983.[1] It is known from the Early Miocene of Africa (Kenya, Uganda, Namibia)[2] and well as possibly the Middle Miocene of China.[3] It is considered a primitive member of the family, retaining a long lower jaw (longirostrine) with lower tusks.[3][4] The upper tusks are small and are parallel to each other. The body mass is considerably smaller than the American mastodon.[5] Dental mesowear from East African specimens suggests a browsing diet.[6]
