Eozygodon is an extinct genus of proboscidean in the family Mammutidae. It is a monotypic genus that contains the 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 skull of the young adult (around 24-26 years old in African elephant tooth wear equivalent years) AM 02 from Auchas, Namibia, was around the size of that of a 10 year old American mastodon,[5] around 60 centimetres (2.0 ft) in maximum length.[6] Some authors suggest that Eozygodon could be less closely related to other members of Mammutidae than other mammutids are to Elephantida, making Mammutidae as typically defined paraphyletic.[5]
