Mammuthus Subplanifrons (previously Loxodonta Adaurora)

Mammuthus subplanifrons, is also known as the South African Mammoth. It is the oldest representative of the genus Mammuthus. It appears in the fossil record around 5 million years ago during the early Pliocene in what is today South Africa, Kenya and Ethiopia. They presented some  unique characteristics of mammoths like the spirally, twisting tusks. It was 3.68 metres (12.1 ft) tall at the shoulder and weighed about 9 tonnes.

A complete skeleton was found in Kanapoi, Kenya. It was initially classified as Loxodonta adaurora. In 2009, it was shown that Loxodonta adaurora is indistinguishable from Mammuthus subplanifrons. The continuously decreasing length of vertebral spines from shoulder to hip and the extreme femur to tibia ratio indicate that this species belongs to Mammuthus, not Loxodonta (Loxodonta spp. have high vertebral spines over the hips, the mid-back having the lowest), and since Mammuthus subplanifrons was named first, that would be the valid name for the species.
