The aurochs or urus (Bos primigenius), the ancestor of domestic cattle, was a type of huge wild cattle which inhabited Europe, Asia and North Africa, but is now extinct; it survived in Europe until 1627.
The aurochs was far larger than most modern domestic cattle with a shoulder height of 2 metres (6.6 ft) and weighing 1,000 kilograms (2,200 lb). Domestication occurred in several parts of the world at roughly the same time, about 8,000 years ago. It was regarded as a challenging quarry animal, contributing to its extinction.
The last recorded live aurochs, a female, died in 1627 in the Jaktorów Forest, Poland and its skull is now the property of Livrustkammaren in Stockholm.
