Archaeologists began studying the site of Aranbaltza in 2013 (Barrika, Bizkaia). The investigation is still unclosed, but they have already seen that it was the residence of Neanderthal groups between 100,000 and 44,000 years ago. They have now announced the discovery of carved wood tools 90,000 years ago.

The research has been directed by Joseba Ríos Garaizar (CENIEH), who has stated that "it is an incredible discovery, very rare". So far, only five places in Europe have found it, including Abric Romanín (Barcelona). "In addition, in Aranbaltza there are options to get more tools in upcoming campaigns," adds Ríos.

In fact, the environment of Aranbaltza is muddy, and thanks to it the wooden tools have been maintained, although they are usually easily undone.

Among the instruments stands out a pointed object of 15 cm. By skin analysis and computed microtomography they have shown that a branch of the tooth was made with a carved and hardened branch in the fire and used to make holes in the ground.

Together with CENIEH researchers, they have worked at INRAP, the Autonomous University of Barcelona and the universities of the Basque Country, Burgos and Cantabria. The finding has been announced in the journal PLOS ONE.
