Breuil in aimed to establish a linear time frame for rock art. Dating is still an area of development and criticism because of the imprecise nature of the material and methods available.
In this practical, student gain an understanding of how cave painters may have used the natural rock formation to paint the animals and scenes onto them and how later painters have continued with this tradition.

How do we analyse to find out if they are as old as we think they are? Radiocarbon dating Radiocarbon dating also called carbon dating only works with organic things; materials that came from living things. Where does the radioactive carbon come from?
How can it tell us how old an organic material is? This can be written as: Carbon typically has 6 neutrons making the isotope carbon 12 C12 , but some carbon atoms have 7 neutrons making carbon 13 C13 and some carbon atoms have 8 neutrons making carbon 14 C Figure 2: Carbon istopes 12, 13, Peter Bull All the time an organism is alive it takes up all forms of the carbon isotopes to make its chemicals but on death it stops taking in any carbon.

Figure 4:Half-life graph of carbon The difficulties with pigments The difficulty with carbon dating pigments is that they are often made from rocks, and do not contain organic matter. What about limestone? Can radiocarbon dating be more accurate? Is radiocarbon dating the only absolute method for dating rock art? Uranium-Series Disequilibrium In a new development allowed the El Costillo paintings in Spain to be dated more accurately, pushing the advent of cave painting back 10, years.
Tito Bustillo Flowstones are formed where water flows down the walls or along the floors of a cave.

The cave paintings were created between 43, and 65, years ago, 20, years before modern humans arrived in Europe.
In , researched announced the discovery of the oldest known cave paintings, made by Neanderthals at least 64, years ago, in the Spanish caves of La Pasiega, Maltravieso and Ardales. Like some other early cave art, it was abstract. Archaeologists who study these caves have discovered drawings of ladder-like lines, hand stencils and a stalagmite structure decorated with ochre.
Neanderthals, an archaic human subspecies that procreated with Homo sapiens , likely left this art in locations they viewed as special, says Alistair W. Pike, head of archaeological sciences at the University of Southampton in the U.
Many of the hand stencils appear in small recesses of the cave that are hard to reach, suggesting the person who made them had to prepare pigment and light before venturing into the cave to find the desired spot.
The markings themselves are also interesting because they demonstrate symbolic thinking. The possible connection between cave art and human language development is something Shigeru Miyagawa, a professor of linguistics and Japanese language and culture at MIT, theorized about in a paper he co-authored for Frontiers in Psychology.
