The technique just might change the way we think about the paintings, and the way we think about our long-extinct, long-maligned Neanderthal cousins as well. The findings being reported today represent just an initial step in an “ongoing program” to date hundreds of European cave paintings more accurately, said the University of Bristol’s Alistair Pike, lead author of a paper published in the journal Science. It’s still too early to say conclusively whether Neanderthals were behind at least some of the artistry. However, Pike and his colleagues are confident that the earliest paintings go back at least 40, years. That time frame matches up with the earliest evidence of the presence of anatomically modern humans in Europe. It’s also thousands of years earlier than the previously accepted maximum age, based on carbon dating. Penn State archaeologist Dean Snow, who wasn’t part of the research team but has worked on some of the same cave paintings that were recently put to the test , was impressed by the results. But he also acknowledged that the latest findings produce “three or four new problems that we didn’t have before. The tests were conducted on 50 Paleolithic paintings in 11 Spanish caves, including the famous pictures of horses and human hands at the Altamira and El Castillo caves. In the past, the paintings have been dated using radiocarbon tests, but Pike’s team used a different technique that analyzed the proportions of uranium, thorium and related elements in the calcite deposits that formed above and below the paintings.

Paleolithic cave art is an exceptional archive of early human symbolic behavior, but because obtaining reliable dates has been difficult, its chronology is still poorly understood after more than a century of study. The results demonstrate that the tradition of decorating caves extends back at least to the Early Aurignacian period, with minimum ages of These minimum ages reveal either that cave art was a part of the cultural repertoire of the first anatomically modern humans in Europe or that perhaps Neandertals also engaged in painting caves.

Uranium-series dating of carbonate formations overlying Paleolithic art: interest and limitations

Dating Me The need for an accurate chronological framework is particularly important for the early phases of the Upper Paleolithic, which correspond to the first works of art attributed to Aurignacian groups. All these methods are based on hypotheses and present interpretative difficulties, which form the basis of the discussion presented in this article. The earlier the age, the higher the uncertainty, due to additional causes of error.

Methods: U/Th and Ra/U dating, Sr isotopes, Pb isotopes, trace elements. U-series dating of carbonate formations overlying Paleolithic art: interest and.

Dating cave art is a key issue for understanding human cognitive development. Knowing whether the ability for abstraction and conveying reality involved in artistic development is unique to Homo sapiens or if it was shared with other species, or simply knowing at what moment these abilities developed, is vital in order to understand the complexity of human evolution.

Currently in Spain, for the most part, when trying to find out the age of artistic expressions in caves, dating is done with U-series dating, using the two elements uranium and thorium in the underlying and overlapping layers of calcite in the paint itself. However, the timeline this system proposes seems to provide evidence for erroneous ages and an inverse relationship between the concentration of uranium and the apparent ages.

The key, according to the team, seems to be in the mobility of uranium, which would have assigned older and inaccurate ages to the cave art in some Spanish caves, ascribing the art to Homo neanderthalensis. The research team analyzed several samples of calcite related to the chronometric test of a set of rocks in the Nerja Cave, obtaining proof of the complexity of the dating on calcite for the study of the chronology of cave art.

Instead of trying to date the paintings and engravings themselves, they are analysing carbonate deposits like stalactites and stalagmites that have formed over them.

This means they don’t risk harming irreplaceable art, and provides a more detailed view of prehistoric cultures.

Although work continues on the surveying and the study of the evidence found up to now, we present here a preview consisting of a representation of a red deer, and also a hand stencil, alongside numerous marks which have been found scattered throughout the inner cave.

Situating this dating in the archaeological context of the stencil, we conclude that it is associated with the Solutrean technocomplexe.

Over the last decade several dozen direct dates on cave art pigments or associated materials have supplemented more traditional style-based attempts to establish a chronological and developmental scheme for cave art. Here, we examine the state-of-the-art of Palaeolithic cave art dating, with particular emphasis on certain radiocarbon and Uranium-series projects. We examine the relative successes and weaknesses of this cutting edge science.

We conclude that there are several weaknesses in current applications that are in serious need of addressing. Issues of sample contamination and of the heuristic relationship between materials dated and the production of the art are particularly problematic.
