The steppe mammoth, Mammuthus trogontherii, is an extinct species of elephant, that ranged over most of northern Eurasia during the Late Pleistocene, 600,000-370,000 KYA.
The steppe mammoth probably evolved in the early Pleistocene of siberia from Mammuthus meridionalis, which was replaced during the middle pleistocene about 750.000 - 500.000 years ago. It was the first stage in hte evolution of the steppe and tundra elephants and an ancestoer of the woolly mammoth of the later glacial periods. Standing up to 4.70 m (15 ft) tall at the shoulder, it is among the largest probiscideans to have ever lived, along with Mammuthus meridionalis and Deinotherium. Its spiral-shaped tusks could be as long as 5.20 m (17 ft) in old bulls. About 250.000 years ago, the woolly mammoth appeared in Europe, which derived in northern Asia from the steppe mammoth and replaced its progenitor completely.
Its skull was shorter than that of the great southern elephant. The males had spiral tusks with a recurved tip, while the females had thinner and only slightly curved tusks. The tusks grew to considerable lengths and the largest one knwon must have measured about 5 m. on a living animal.
The most complete skeleton of a steppe mammoth yet found was discovered in 1996 in Kikinda, Serbia. It has recently been mounted and put on display. The specimen is a female, which was about 4.7 m (15½ ft) high, with 3.5 m (11½ ft) long tusks, and would have weighed an estimated 7 tonnes when alive. This suggests even greater dimensions for males from the same area. It therefore seems that M. trogontherii is not only the biggest species of the genus Mammuthus, but is possibly among the biggest species in the order Proboscidea, rivaling in size not only Elephas recki and the Straight-tusked elephant Palaeoloxodon but, perhaps, even Deinotherium itself.
