Rock fragment bearing traces of a charcoal drawing, carbon-dated to 26, BCE. Found at the aboriginal rock shelter of Nawarla Gabarnmang in Arnhem Land, Northern Territory, is the oldest work of art ever found on the continent of Australia. Hand Stencil Painting. Aboriginal art, Kimberley Region. Handprints and cupules are believed to constitute the oldest forms of aboriginal parietal art in Australia, dating perhaps to 40, BCE. However, this remains unconfirmed by carbon-dating results. Bradshaws now called Gwion art are among the most sophicated forms of cave painting in Australia.
Rock Art Dating Methods
A new dating method finally is allowing archaeologists to incorporate rock paintings — some of the most mysterious and personalized remnants of ancient cultures — into the tapestry of evidence used to study life in prehistoric times. In the study, Marvin W. Rowe points out that rock paintings, or pictographs, are among the most difficult archaeological artifacts to date. They lack the high levels of organic material needed to assess a pictograph’s age using radiocarbon dating, the standard archaeological technique for more than a half-century.

Radiocarbon dating has had a significant impact on rock art research, but an initial enthusiasm for this dating method by archaeologists has been replaced by a degree of scepticism. Radiocarbon dates undertaken directly on rock art or on associated mineral crusts have often reinforced such scepticism, in part because organic carbon-based materials are present in small quantities and their composition is of such variable composition that the technique is stretched to its limits.
For the researcher planning to obtain radiocarbon dates, it is essential to have an understanding of the dating options available, limitations of the technique, the potential impact of their own bias, and the value of a dating programme that is fully integrated within a larger project. This chapter outlines the various materials and methods used to radiocarbon date rock art.
It includes some recent examples and highlights some advances as well as shortfalls in the dating of rock art. Keywords: radiocarbon , oxalate , carbon black , Bayesian chronology.
Follow our live coverage for the latest news on the coronavirus pandemic. Enigmatic human figures with elaborate headdresses, arm and waist decorations adorn rock shelters in the Kimberley region of Western Australia. This style of art, known as Gwion, Kiro Kiro or Kujon, was painted by the ancestors of today’s traditional owners around 12, years ago, a new study suggests. The date of the art work, published today in the journal Science Advances , is based on radiocarbon dating of mud wasp nests.
As the traditional owners used fire to manage their country, the small black and yellow wasp built their time capsules above and below the artworks tucked away in the rock shelters. While most Gwion paintings studied by the team had either had a nest under or over part of the artwork, one painting had two nests on top and one under.
The Gwion period, which used to be known as the Bradshaw paintings, is thought by archaeologists to be the second oldest of at least six distinct periods of creative styles depicting stories and songlines passed from generation to generation. I just say ‘I don’t know, it’s just older than me or you,” Mr Waina said. Is it from our older, older, older people?
Petroglyphs and Pictographs
If you would like to be involved in its development, let us know – external link. Scientists are revolutionising our understanding of early human societies with a more precise way of dating 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.
Dating rock art can be problematic, especially for carvings. We do have indirect evidence to help us, however. Cup-and-ring carved rocks are sometimes found in prehistoric monuments with a known date, and this tells us that the carvings were created before or at the same time as the monuments. Researchers now believe that they were first created in the Neolithic period around years ago. This is supported by the discovery of cupmarked rocks in Neolithic monuments, such as the long cairn at Dalladies in Aberdeenshire, dating to BC.
Excavations of a rock art panel at Torbhlaren near Kilmartin, Argyll has also provided Neolithic dates from deposits on and around the rock surface, whilst in Northumberland, excavations of a carved rock at Hunterheugh revealed that an Early Bronze Age burial had been built over earlier, eroded motifs. You can read more about this research on our Other Research page. Many questions remain, however.
Rock art dating
The axiom that rock art is notoriously difficult to date serves only to paint a partial picture of the inconsistent and contested chronological records of rock art in Africa. For example, where research has focused on interpretation, chronology has been less prominent and as such the capacity for judging meaningful relationships between sites and imagery has been inhibited; by contrast where chronologies have led research agendas, the temporal and spatial relationships are much clearer, but chronologies are hotly disputed.
A significant obstacle is the challenge in directly dating rock art, and current research is exploring ways forward in refining these techniques.
Kimberley Rock Art ( BCE): Gwion, Bradshaw, Wanjina Paintings of Western Australia.
The RAD-2 project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley and an innovative combination of four scientific dating methods developed in the earlier work. The project expects to establish a well-dated sequence for Kimberley rock art based on replication of results and confirmation across different methods, all conducted in collaboration with Traditional Owners.
OSL dating is based on the principle that quartz grains accumulate electrons over time but when exposed to sunlight all of these electrons are expelled-resetting the clock. This grain is then buried within the nest and allowed to accumulate electrons again- if we measure how many electrons there is we know how long that nest has been there and that the painting underneath must be older.
U-series is usually applied to calcite in limestone environments. The remarkable finding of the last 12 months has been that it can be applied to phosphate minerals in the exposed sandstone environments of the Kimberley- a world first. These minerals precipitate out from water which contains a certain level of Uranium but no Thorium. Over time the U decays to Th and by measuring the amount of each we can work out how long that mineral layer has been over the art surface-and that the painting must be older.
The mineral accretion is a mounted and polished piece that gives a cross-section through the detailed internal stratigraphy layers. The overlaid scans are laser ablation trace element maps the laser vaporises a bit of material in each layer and sends it to the mass spectrometer which analyses the concentration of certain elements – in this case they are showing us where Uranium is focussed.

Mud wasps also furnish their nests with paralyzed spiders or caterpillars. When an organism is living it is constantly exchanging the radioactive isotope carbon 14 with the atmosphere.
Rock Art Dating Methods: Problems and Solutions
A major limitation in rock art studies is that rock art can be difficult to date. The dating techniques currently in use fall into two broad categories: relative dating and absolute dating. Relative dating techniques include observations of patterns of chemical and physical weathering , evidence that art has been painted over, stylistic patterns, and variations in the spatial patterns of rock art indicating chronological sequences of site occupation.
Absolute dating methods include analyses based on subjects depicted e. Occasionally, it has been possible to date rock art directly by chemically analyzing the organic materials that were used to draw it, for example, charcoal, plant fibers, and protein binders.

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. Moreover, the ages obtained by carbon do not correspond to exact calendar years and thus require correction.
It is for this reason that the period corresponding to the advent of anatomically modern humans Homo sapiens sapiens in Europe and the transition from Neanderthal Man to modern Man remains relatively poorly secured on an absolute time scale, opening the way to all sorts of speculation and controversy. As long as it is based on dates with an accuracy of one to two thousand years and which fluctuate according to calibration curves and the technical progress of laboratories, our reasoning remains hypothetical.
In such a fluctuant context, it would be illusory to place the earliest artistic parietal and portable representations from the Swabian Jura, the southwest of France, the Rhone Valley, Romania or Veneto on a relative timescale. Most of this paper will deal with carbon as it is the only direct dating method applicable to parietal art although it is limited to charcoal drawings.
In most cases, these methods provide a minimum age, a terminus ante quem that can be far removed from the archeological reality, as deposits can form quite late on and in an intermittent way. But other causes of error can increase uncertainty, some of which can even contribute to yielding abnormally high ages.
Rock (Art) of Ages: Indonesian Cave Paintings Are 40,000 Years Old
The sites are in the eastern part of Spain and contain rock art dating to the Upper Paleolithic or more likely Mesolithic periods of the Stone Age. The art consists of small painted figures of humans and animals, which are the most advanced and widespread surviving from this period, certainly in Europe, and arguably in the world, at least in the earlier works. It is notable for the number of places included, the largest concentration of such art in Europe.
Its name refers to the Mediterranean Basin ; however, while some sites are located near the sea, many of them are inland in Aragon and Castilla—La Mancha ; it is also often referred to as Levantine Art meaning “from Eastern Spain”, not the Levant region.
Although pigments and other materials used in painted rock art can often be precisely dated (also called absolute dating) with scientific techniques, such as.
By Bruce Bower. February 5, at pm. In a stinging rebuke of that idea, a new study suggests that most of these figures were painted much more recently — around 12, to 11, years ago. Geoscientist Damien Finch of the University of Melbourne in Australia and his colleagues radiocarbon dated small, hardened pieces of 24 mud wasp nests positioned partly beneath or partly on top of 21 Gwion-style rock paintings, thus providing maximum and minimum age estimates.
The dated paintings came from 14 Aboriginal rock art sites. Gwion art depicts elaborately garbed human figures and objects such as boomerangs and spears. Most radiocarbon dates from the mud wasp nests indicate the Gwion figures were painted around 12, years ago, at least 5, years later than typically thought, the scientists report February 5 in Science Advances. Radiocarbon evidence from a nest partly overlying one of the paintings, however, suggests it was, in fact, created about 17, years ago or more, they say.
That investigation dated the time since quartz particles in a mud wasp nest overlying a Gwion figure were last exposed to sunlight. But some rock art researchers disagree about whether that age estimate was accurate. Radiocarbon dating of mud wasp nest remains needs to be combined with other rock art dating approaches, including the method from the study, to evaluate additional Gwion paintings, says archaeologist June Ross of the University of New England in Armidale, Australia.
Once securely dated, Gwion art will provide insights into ancient Aboriginal cultural practices and social life, predicts Ross, who did not participate in the new study.
