90.000 Year-Old Neanderthal Wood Tools Found in Spain
The Micro-CT analysis and a close examination of the surface developed at CENIEH laboratories have shown that a yew trunk was cut longitudinally into two halves. One of this halves was scraped with a stone-tool, and treated with fire to harden it and to facilitate the scraping to obtain a pointed morphology. Use-wear analysis revealed that it was used for digging in search of food, flint, or simply to make holes in the ground.
The preservation of wooden tools associated to neanderthals is very rare because wood degrades very quickly. Only in very specific environments, like the waterlogged sediments from Aranbaltza, it has been possible to find evidence of wooden technology. As it was suggested by indirect evidence, this type of technology was relevant in neanderthal daily life.
In the Iberian Peninsula wooden tools associated to neanderthals have been found only in the travertine from Abric Romaní (Catalonia), and in the rest of Europe only four sites (Clacton on Sea, Schöningen, Lehringen and Poggeti Vechi) have provided wooden tools associated to neandertals or pre-neandertals. Therefore, findings like the one from Aranbaltza are crucial to investigate the neandertal technology and use of wood.
The archaeological project at Aranbaltza started in 2013 to investigate the last neandertals from Western Europe, who were responsible of the Chatelperronian culture. The ongoing excavations have revealed different neandertal occupation events spanning from 100 to 44.000 years. This makes of Aranbaltza an exceptional site to investigate neandertal evolution and behavioral variability.
This project is coordinated by the CENIEH and INRAP and funded by Heritage Center of the Bizkaia Regional Government (2013-2017) and Basque Government (2014-2015). Researchers from the following institutions have participated in this publication: CENIEH, Universidad Autónoma de Barcelona, Universidad de Burgos, INRAP, Universidad del País Vasco and Universidad de Cantabria.
