Located at Fuente Nueva-3, this Early Pleistocene archaeological site hosts some of the oldest traces of human habitation in Western Europe.
Researchers at the University of Malaga have revealed, in an unprecedented manner, that the Early Pleistocene archaeological site of Orce, often referred to as the ‘elephant graveyard’ due to the abundance of remains from the extinct elephant

Thus, these scientists have analyzed the statistical differences in the composition of the faunal assemblages preserved in these two levels and the sedimentology, specifically the particle size in the fertile layers of both levels. The latter is a key aspect in the research, as it shows a predominance of silts and clays in layers 2-3 of the lower level, and fine and very fine sands in layer 5 of the upper level.
“These fine sand sediments, deposited close to the paleolake that was in the region, would also contain slightly saline water, a mixture that explains that they could have worked as quicksand, where larger animals were trapped,” said the UMA scientists.
Food for scavengers
Therefore, experts point out that the latter level may be interpreted as a natural quicksand trap in which megaherbivores were trapped due to the elevated weight of their limbs, and their half-sunken carcasses attracted the scavengers, both hyenas and humans, which fed on these and left their lithic assemblages and coprolites –fossilized excrement of hyenas– as evidence of their presence.
The new finding discovered by UMA researchers represents a “very important milestone to gain more knowledge about the subsistence strategies of our ancestors, the first Europeans, and their competition with the large carrion hyenas for access to these meat resources, since it is the first time a natural trap with these characteristics has been described in a fossil deposit of special interest to human evolution.”
Carrying out more detailed studies differentiating the upper and lower archaeological levels, as well as characterizing other important sites in the Orce region, such as Barranco León, which also contributes evidence of human presence, are the next steps planned by this scientific team of the UMA, in which researchers from the Complutense University of Madrid and Tarragona also participate.
More than a decade of UMA research in Orce
The University of Malaga has been researching the site of Fuente Nueva 3 for several decades. The first publication of the UMA that highlighted the significance of this place, in 2013, described a partial elephant skeleton surrounded in part by flint flakes and coprolites, attesting to the competition between these two super-scavengers for the carcass resources.
