The Atapuerca Mountains (Sierra de Atapuerca in Spanish) is an ancient karstic region of Spain, in the province of Burgos and near the town of the same name and Ibeas de Juarros. It contains several caves, where fossils and stone tools of the earliest known Hominians in West Europe have been found. There have been found fossils of the categories Homo Antecessor, Homo Heidelbergensis and Homo Sapiens. The fossils include various skulls, for example the complete cranium (Skull 5), nicknamed Miguelón and a complete pelvis (Pelvis 1), nicknamed Elvis, in remembrance of Elvis Presley, which belonged to a man of 175 cm height and 95 kilos of weight. Furthermore, a biface called Excalibur. was found. It is hypothesized that this Acheulean axe made of red quartzite was some kind of ritual offering for a funeral.
