In August of 1964, a humerus was found by Jose Miguel Barandiarán and Jesus Altuna in the Lezetxiki cave in Mondragón, Gipuzkoa. After 50 years of the finding, scientist have determined the age of this bone. The humerus, which is 164, 000 years old, is one of the oldest remains of the peninsula, the oldest found in Euskadi. Just a couple of remains of Atapuerca are more ancient than this one.
Jesus Altuna, one of the paleoanthropologists that found the bone, has remarked that even if until now the age of the bone was not set, they knew that the remain was older than 120,000 years because in an upper level of the cave they found pieces of the skull of a bear who lived before the cave bears and was extinguished in Europe by this period.
The study was carried out in the National University of Australia and they used the uranium/lead method to determinate the age because the ressults obtained by the C14 would be inconclusive. They have also obtained the DNA from the humerus in order to identify the species and the sex of this remain.
