Paleolithic paintings in El Castillo cave in Northern Spain date back at least 40, years - making them Europe's oldest known cave art, according to new research published June 14 in Science. The research team was led by the University of Bristol and included Dr Paul Pettitt from the University of Sheffield's Department of Archaeology, a renowned expert in cave art. Their work found that the practice of cave art in Europe began up to 10, years earlier than previously thought, indicating the paintings were created either by the first anatomically modern humans in Europe or, perhaps, by Neanderthals. As traditional methods such as radiocarbon dating do not work where there is no organic pigment, the team dated the formation of tiny stalactites on top of the paintings using the radioactive decay of uranium. This gave a minimum age for the art. Where larger stalagmites had been painted, maximum ages were also obtained. Hand stencils and disks made by blowing paint onto the wall in El Castillo cave were found to date back to at least 40, years, making them the oldest known cave art in Europe, , years older than previous examples from France.

The pre-Gravettian signs large dots, disks, and the claviform-like symbol and hand stencils that we dated are sim- ilar to many found in other caves across Europe, although use of particular symbols may differ regionally The apparent lack of further pre- Gravettian examples elsewhere in Europe is more likely the result of targeting charcoal-based black pigments with radiocarbon dating and the result- ing ambiguities than a genuine absence of pre- Gravettian images.
Our results are consistent with the notion that there was a gradual increase in technological and graphic complexity over time, as well as a grad- ual increase in figurative images. Our earliest dates pre-Gravettian are for art that is nonfigu- rative and monochrome re supporting the no- tion that the earliest expression of art in Western Europe was less concerned with animal depic- tions and characterized by red dots, disks, lines, and hand stencils.
If the earliest cave paintings appeared in the region shortly before However, because the Paleolithic cave art is an exceptional archive of early human symbolic behavior, but because obtaining reliable dates has been difficultits chronology is still poorly understood after more than a century of study. Where suitable material exists e. Discrepancies between multiple 14 C determinations on a single painted motif have been commonas are discrepancies between the dates of different chemical e.
Our U-series ages ranged from 0. All we care about is that the measurements ranged from years to 40, years, which hardly inspires confidence in the method. We should also explain the difference between calendar years and radiocarbon years.
So, correction coefficients have been developed for historic times to convert radiocarbon years accurately to calendar years. Those correction coefficients have been extrapolated to prehistoric times based on presumed prehistoric CO 2 levels. They use a tricky method we will explain in a moment. The tricky method they use tells more about the age of the Earth than it does about the age of the paintings.
Back to their method of dating the paintings : Anyone who has been to a cave knows stalactites, stalagmites, columns, and draperies form gradually in caves. These cave formations are simply differently shaped deposits of minerals such as calcite on the floor, walls, and ceiling of caves. Ancient cave art is painted on one layer of these deposits, and covered by another layer. If one can tell how old the layer under the painting is, and how old the layer over the painting is, then one can set upper and lower bounds on the age of the painting.
This means one can date the painting by taking samples from the wall near the painting without damaging the painting itself. The method is described in the supplementary material on the Science website, but not published in the journal itself. The Uranium-series disequilibrium method.
Differential solubility between uranium and its long lived daughter isotope Th means that calcite precipitates e. Over time, there is ingrowth of Th from the radioactive decay of U until radioactive equilibrium is reached where all isotopes in the series are decaying at the same rate. An additional problem is the incorporation of detritus in the precipitating calcite. This can be from wind-blown or waterborne sediments. Detrital sediments will bring U and Th and usually will result in the apparent age of a contaminated sample to be an overestimate of the true age.
However, the presence of the common thorium isotope, Th, indicates the presence of contamination, and there are several methods to correct the U-series date for it. Note the conservative error on this assumption.
While the date obtained using measured detritus values agrees within error in both cases with the date using an average crustal silicate, we must be cautious in using dates corrected using the insoluble detritus.
To be cautious therefore, we base our interpretation of the dates for samples O and O on dates corrected with our assumed rather than measured detrital value. First of all, notice the assumption that when water seeps through the ground and dissolves minerals, it dissolves some uranium, but no thorium.
Therefore, when the water evaporates in the cave, leaving the minerals behind on the cave wall, there is some uranium but no thorium when the flowstone first formed.
Later, they presume, some of the uranium decays to produce all the thorium in the flowstone.
Is that assumption reasonable? Can one really assume that no thorium was present in the water that evaporated to form the flowstone?
How much thorium would it take to produce a false old age for a modern formation? Not much, as we will see, later. Second, the method depends upon equilibrium or lack thereof. The assumption is that the newly formed flowstone contains uranium but no thorium. As time goes by, the uranium will decay resulting in less uranium and more thorium. So the thorium will start to build up. But thorium decays much more rapidly than uranium.
Eventually, the rate at which the thorium decays will equal the rate at which it is being produced by the decay of uranium. Imagine a bucket with a hole in it. You start filling it with water from a garden hose. As the level in the bucket rises, the increasing water pressure causes water to leak out of the hole faster.

A large club-shaped symbol in the famous polychrome chamber at Altamira was found to be at least 35, years old, indicating that painting started there 10, years earlier than previously thought, and that the cave was revisited and painted a number of times over a period spanning more than 20, years.
Dr Pike said: "Evidence for modern humans in Northern Spain dates back to 41, years ago, and before them were Neanderthals. Our results show that either modern humans arrived with painting already part of their cultural activity or it developed very shortly after, perhaps in response to competition with Neanderthals - or perhaps the art is Neanderthal art.
U-Series Dating of Paleolithic Art in 11 Caves in Spain Article ( Available) in Science June with 2, Reads How we measure 'reads'. U-Series Dating of Paleolithic Art in 11 Caves in Spain. U-Series Dating. Attempts to date cave paintings illustrate the difficulties of radiometric dating, and also show evidence of a young earth. A recent article about U-series dating of Paleolithic art in 11 caves in Spain 1 contained some frank discussions about the wild assumptions that had to be made to date the paintings, and raised some interesting questions about the scientifically accepted.
The creation of art by humans is considered an important marker for the evolution of modern cognition and symbolic behaviour, and may be associated with the development of language. Dr Pike said: "We see evidence for earlier human symbolism in the form of perforated beads, engraved egg shells and pigments in Africayears ago, but it appears that the earliest cave paintings are in Europe. One argument for its development here is that competition for resources with Neanderthals provoked increased cultural innovation from the earliest groups of modern humans in order to survive.
Alternatively, cave painting started before the arrival of modern humans, and was done by Neanderthals. That would be a fantastic find as it would mean the hand stencils on the walls of the caves are outlines of Neanderthals' hands, but we will need to date more examples to see if this is the case.
The findings are particularly significant because cave art has always been difficult to date accurately. Dr Pike said: "Engravings and, in many cases, paintings lack organic pigments or binders suitable for radiocarbon dating.
