The steppe mammoth (Mammuthus trogontherii or Mammuthus armeniacus) is an extinct species of Elephantidae that ranged over most of northern Eurasia during the Middle Pleistocene, 600,000-370,000 years ago. It probably evolved in Siberia during the early Pleistocene from Mammuthus meridionalis. It was the first stage in the evolution of the steppe and tundra elephants and an ancestor of the woolly mammoth of later glacial periods.
