The Xiaogushan cave site is one of the most important prehistoric sites in North China. The stone and bone artifacts found in the cave are similar to European contemporaneous artifacts. In this paper, optically stimulated luminescence OSL techniques were applied to date six samples taken from Layers The luminescence properties of the fine-grained and coarse-grained quartz extracts indicate that the materials are suitable for OSL dating using a single-aliquot regeneration-dose SAR protocol. The OSL ages obtained are broadly consistent with the stratigraphy and the associated calibrated radiocarbon ages. The dating results show that the cave was first occupied by humans about 70 ka. The human occupation of the cave may be related to climate change. The stone and bone artifacts found in Layers 2 and 3 may indicate the Middle to Upper Paleolithic transitions in the region.

Elisa J. Geology ; 33 4 : — The long-term recurrence patterns of past earthquakes are of considerable consequence for hazard assessments, and have implications for earthquake physics. We introduce a rigorously dated record of earthquakes from an extensive number of well-preserved preseismic and postseismic precipitates from caves located off the Dead Sea transform. We dated events directly at the paleoseismic contact by means of a novel correlation method with the oxygen isotope record of the speleothems recovered in one of the caves.
Cosmogenic Isotope Dating of sediments. Such methods can provide a geomorphic record of cave ages and river system evolution over the past 5 million years.
Found deep in Spanish caves, the rock art was once thought to be the work of modern humans, but the new dates mean that Neanderthals must have figured out fingerpainting, too. Using a new and improved radioactive dating technique, researchers discovered that paintings in three different caves were created more than 64, years ago. That means the paintings were created 20, years before modern humans, or Homo sapiens , arrived in Spain, according to a study published today in the journal Science.
The discovery makes these the oldest examples of cave paintings in the world and the first to be attributed to Neanderthals. Neanderthals are our closest extinct relative, but for a long time, they had a reputation for being pretty backward. Early modern humans, for example, made cave paintings. But even though Neanderthals used pigments and decorated themselves with eagle claws and shells , there was no clear proof that they painted caves.
One theory goes that Neanderthals developed their rudimentary culture only after early modern humans arrived in Europe some 40, to 50, years ago. The discovery adds to a growing body of evidence upending the idea that Neanderthals were less evolved than early modern humans, says Marie Soressi , an archaeology professor at the University of Leiden who was not involved in the research.
But it required lots of material to come up with a date, and cave paintings are too rare to risk damaging.
Painting of a Bison c. Polychrome Animal Painting from Altamira c. Altamira Cave Paintings: A Summary. Located in northern Spain, not far from the village of Antillana del Mar in Cantabria, the Upper Paleolithic cave complex at Altamira is famous for its magnificent multi-coloured cave painting , as well as its rock engravings and drawings. It is one of seventeen such caves unearthed along the mountains of North Spain near the Atlantic coast, on the main migratory route from the Middle East, which followed the North African coast, crossed the sea at Gibraltar and led through Spain into France.

Other researchers say the discovery is important because the animal paintings are also the oldest figurative artworks — those that clearly depict objects or figures in the natural world — on record.
They suggest it might be a series of images painted over the course of perhaps thousands of years. The site, discovered in , includes hundreds of animal figures painted around 17, years ago.

Countless caves perch atop the steep-sided mountains of East Kalimantan in Indonesia, on the island of Borneo. Draped in stone sheets and spindles, these natural limestone cathedrals showcase geology at its best. But tucked within the outcrops is something even more spectacular: a vast and ancient gallery of cave art.
Hundreds of hands wave in outline from the ceilings, fingers outstretched inside bursts of red-orange paint. Now, updated analysis of the cave walls suggests that these images stand among the earliest traces of human creativity, dating back between 52, and 40, years ago. That makes the cave art tens of thousands of years older than previously thought. The new dating analysis suggests that these images are at least 40, years old, earning them the title of the earliest figurative cave paintings yet found.
With a minimum age of 40, years, a trio of cow-like creatures, seen here in a composite image, is considered to be the oldest figurative artwork yet found.
Until the s, information contained within cave sediments was thought to be limited to just:. Archaeological deposits such as animal and human remains. Information gleaned by visual examination of the stratigraphy of sedimentary layers. This can determine depositional environment, sediment origin, relationship of sediments to cave or landscape development, long-term depositional or erosion trends, and relationships of fossils or artifacts to cave processes.
Then in it was discovered that the rate of decay of a radioactive isotope of carbon Carbon could be used to provide ages for organic samples such as bone, charcoal, etc.

Modern critics would probably hail the up and coming rock artists that once inhabited Indonesia. About a hundred caves outside Moras, a town in the tropical forests of Sulawesi, were once lined with hand stencils and vibrant murals of abstract pigs and dwarf buffalo. Today only fragments of the artwork remain, and the mysterious artists are long gone. Swiss naturalists Fritz and Paul Sarasin returned from a scientific expedition to Indonesia between to with tales of ancient rock shelters, artifacts and cave paintings, but few specifics.
Dutch archaeologist H. Work by local scientists describes more recent charcoal drawings that depict domesticated animals and geometric patterns. It also mentions patches of potentially older art in a red, berry-colored paint—probably a form of iron-rich ochre —that adorns cave chamber entrances, ceilings and deep, less accessible rooms. Previous estimates put the Maros cave art at no more than 10, years old. Dating cave paintings can prove extremely difficult. Radiocarbon dating can be destructive to the artwork and can only be used to date carbon-containing pigment—usually charcoal.
This method also gives you the age of the felled tree that made the charcoal, rather than the age of the charcoal itself.
Mount Granier lies in the northeast corner of the Chartreuse Mountains. It contains a vast cave system, whose uppermost levels were thought to be of pre-Quaternary age. Data from karst deposits serve as reference and comparison site for Alpine chronology as well as for cave genesis and palaeogeographical reconstructions, similar to that of the Siebenhengste massif in Switzerland.
Comparisons of the methods used and the results obtained from one end of the Alpine chain to the other have provided an overview of the state of knowledge of Alpine cave genesis.

New ages for flowstone, sediments and fossil bones from the Dinaledi Chamber are presented. We combined optically stimulated luminescence dating of sediments with U-Th and palaeomagnetic analyses of flowstones to establish that all sediments containing Homo naledi fossils can be allocated to a single stratigraphic entity sub-unit 3b , interpreted to be deposited between ka and ka.
This result has been confirmed independently by dating three H. We consider the maximum age scenario to more closely reflect conditions in the cave, and therefore, the true age of the fossils. By combining the US-ESR maximum age estimate obtained from the teeth, with the U-Th age for the oldest flowstone overlying Homo naledi fossils, we have constrained the depositional age of Homo naledi to a period between ka and ka. These age results demonstrate that a morphologically primitive hominin, Homo naledi, survived into the later parts of the Pleistocene in Africa, and indicate a much younger age for the Homo naledi fossils than have previously been hypothesized based on their morphology.
Species of ancient humans and the extinct relatives of our ancestors are typically described from a limited number of fossils. However, this was not the case with Homo naledi. More than fossils representing at least 15 individuals of this species were unearthed from the Rising Star cave system in South Africa between and Found deep underground in the Dinaledi Chamber, the H. After the discovery was reported, a number of questions still remained.
Not least among these questions was: how old were the fossils? The material was undated, and predictions ranged from anywhere between 2 million years old and , years old.
Cave art is one of the first expressions of human symbolic behaviour. It has been described as one of our trade marks as Anatomically Modern Humans Homo sapiens and it is something that, up to days ago, defined us as a species. However, we recently learned that Neanderthals had some kind of symbolic behaviour, though its extent is still largely unknown. So how do archaeologists know the age of the cave paintings in places like Altamira or Lascaux? We cannot use the usual tools applied in other archaeological fields, so we have to rely on different methods to determine when they were made and in turn by whom!
Broadly speaking, Palaeolithic cave art appeared around 40, years ago and continued until 12, years ago.

By Bruce Bower. October 28, at am. Ancient European cave paintings recently attributed to Neandertals have ignited an ongoing controversy over the actual age of those designs and, as a result, who made them. An international group of 44 researchers, led by archaeologist Randall White of New York University, concludes that the controversial age estimates, derived from uranium-thorium dating, must be independently confirmed by other dating techniques. Those approaches include radiocarbon dating and thermoluminescence dating, which estimates the time since sediment was last exposed to sunlight.
The team that dated the Spanish paintings, led by geochronologist Dirk Hoffmann of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, stands by its original analysis and will submit a response to the latest critique of its findings to the Journal of Human Evolution. Critics of the age estimates had suggested previously that Hoffmann and his team had mistakenly dated cave deposits unrelated to the Spanish rock art , resulting in excessive age estimates.
Now, the latest chapter of this debate revolves around the reliability of uranium-thorium, or U-Th, dating. In that case, U-Th dates for the rock art would be misleadingly old, the researchers argue. The other side of that same figure received a U-Th date of about 3, years.
Using a new and improved radioactive dating technique, researchers discovered that paintings in three different caves were created more than.
By Michael Marshall. After squeezing through a narrow passage, he found himself in a hidden cavern , the walls of which were covered with paintings of animals. Could the bones of cave bears settle the debate? Lawson accepts the radiocarbon findings. Two years later they argued that the cave walls were still chemically active, so the radiocarbon dating could have been thrown out by changes over the millennia to the pigments used to create the paintings Antiquity , vol 77, p To try to settle the controversy, Jean-Marc Elalouf of the Institute of Biology and Technology in Saclay, France, and his team have turned to the remains of cave bears.
Along with mammoths and other huge mammals, cave bears Ursus spelaeus dominated the European landscape until the end of the last ice age. The Chauvet cave contains several depictions of cave bears, and Elalouf argues that these must have been painted while the bears still thrived in the area. To pin down when the bears disappeared, his team collected 38 samples of cave bear remains in the Chauvet cave and analysed their mitochondrial DNA.
They found that almost all the samples were genetically similar, suggesting the cave bear population was small, isolated and therefore vulnerable.
