The interest in these findings lies in the fact that it is the most modern piece of the kind so far regarding the Neanderthal period and the first one found in the Iberian Peninsula. This circumstance widens the temporary and geographical limits that were estimated for this kind of Neanderthal ornaments. This would be "the last necklace made by the Neanderthals," according to Antonio Rodríguez-Hidalgo.

"Neanderthals used eagle talons as symbolic elements, probably as necklace pendants, from the beginnings of the mid Palaeolithic," notes Antonio Rodríguez-Hidalgo. In particular, what researchers found in Cova Foradada are bone remains from Spanish Imperial Eagle (Aquila Adalberti), from more than 39,000 years ago, with some marks that show these were used to take the talons so as to make pendants. The found remains correspond to the left leg of a big eagle. By the looks of the marks, and analogy regarding remains from different prehistorical sites and ethnographic documentation, researchers determined that the animal was not manipulated for consumption but for symbolic reasons. Eagle talons are the oldest ornamental elements known in Europe, even older than seashells Homo sapiens sapiens perforated in northern Africa.

发现属于chatelperronian文化, typical from the last Neanderthals that lived in Europe, and coincided with the moment when this species got in touch with Homo sapiens sapiens, from Africa -and expanding from the Middle East. Actually, Juan Ignacio Morales, researcher in the program Juan de la Cierva affiliated at SERP and signer of the article, presents this use of eagle talons as ornaments could have been a cultural transmission from the Neanderthals to modern humans, who adopted this practice after reaching Europe.

Cova Foradada covers the most meridional châtelperronian culture site in Europe. The discovery involved a change in the map of the territory where the step from Middle Palaeolithic to Upper Palaeolithic took place 40,000 years ago, and where interaction between Neanderthals and Homo sapiens sapiens probably took place. Studies in Cova Foradada started in 1997. At the moment, the supervision of the excavation is led by Juan Ignacio Morales and Artur Cebrià. The archaeological study of this site is included in a SERP project funded by the Department of Culture of the Catalan Government and another funded by the Ministry of Science, Innovation and Universities, headed by UB professor and SERP director Josep M Fullola.
