Woolly Mammoth

The woolly mammoth (Mammuthus primigenius) is an extinct species of mammoth that lived from the Middle Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with the African Mammuthus subplanifrons in the early Pliocene. The woolly mammoth began to diverge from the steppe mammoth about 800,000 years ago in Siberia. Its closest extant relative is the Asian elephant. The Columbian mammoth (Mammuthus columbi) lived alongside the woolly mammoth in North America, and DNA studies show that the two hybridised with each other. Mammoth remains were long known in Asia before they became known to Europeans. The origin of these remains was long debated and often explained as the remains of legendary creatures. The mammoth was identified as an extinct elephant species by Georges Cuvier in 1796.

The appearance and behaviour of the woolly mammoth are among the best studied of any prehistoric animal because of the discovery of frozen carcasses in Siberia and North America, as well as skeletons, teeth, stomach contents, dung, and depiction from life in prehistoric cave paintings. It was roughly the same size as modern African elephants. Males reached shoulder heights between 2.67 and 3.49 m (8 ft 9 in and 11 ft 5 in) and weighed between 3.9 and 8.2 t (3.8 and 8.1 long tons; 4.3 and 9.0 short tons). Females reached 2.3–2.6 m (7 ft 7 in – 8 ft 6 in) in shoulder heights and weighed between 2.8–4 t (2.8–3.9 long tons; 3.1–4.4 short tons). A newborn calf weighed about 90 kg (200 lb).
