New dates place Sungir as one of the earliest mid Upper Palaeolithic burials at ca. 30,000BP

The site of Sungir (Russia) is well-known for its rich burials of 8 individuals, associated with spears made of mammoth ivory, ivory beads and perforated fox teeth. In the past, the radiocarbon dating of material from this site has proven extremely challenging. So far, three labs obtained direct AMS dates from the skeletal material but the results vary greatly, from 19,000 to 27,000 BP. A new study, published in PlosOne, now obtained a new set of dates using a new method to avoid the known human contamination on the bones themselves.

The authors use High Performance Liquid Chromatography (HPLC) to separate single amino acids, such as hydroxyproline, on samples from both Sungir 1 and 4. This pretreatment method separates the compound of interest from the rest of the bone matrix rather than attempt to remove contamination from the bone collagen itself using macromolecular methods. The new date for the Sungir 1 burial is older than the previously determined results, indicating that there is a modern contamination in the bones from Sungir. This modern contamination, in the form of consolidants that may have been applied during curation and storage, was indeed identified through further infrared scanning of the bones.

'Rare find' of Ice Age tools at Guildford fire station site

More than 2,400 flints shaped into tools and blades have been dug up by archaeologists

Ancient artefacts uncovered at the building site for the new Guildford fire station have been dated back to the Ice Age.

More than 2,400 flints shaped into tools and blades were dug up by archaeologists in the summer and are said to be 14,000 years old.

Nick Truckle, a member of the Surrey County Council heritage conservation team, recommended the dig and said the rare artefacts were in excellent condition, and despite river flooding and development they were found exactly where hunter-gathers had left them in around 12,000 BC...

11,000-Year-Old Seafaring Indian Sites Discovered on California Island

Just offshore from the chock-a-block development of Southern California, archaeologists have discovered some of the oldest sites of human occupation on the Pacific Coast.

On Santa Rosa Island, one of the Channel Islands just 65 kilometers from Santa Barbara, nearly 20 sites have been found that reveal signs of prehistoric human activity, from massive middens of abalone shells to distinctive stone points and tool-making debris.

At least nine of the sites have what archaeologists say is “definitive evidence” of ancient Paleoindian occupation, about half of them having been dated to 11,000 to 12,000 years ago — making their inhabitants some of the earliest known settlers of North America’s West Coast.

“Finding these sites and the definitive evidence for early occupation is crucial and tells us that people were there, occupying the landscape at the end of the Pleistocene,” said Dr. Torben Rick of the Smithsonian Institution, who led the survey that uncovered the sites.

The discovery adds hefty new data to the already mounting evidence that maritime Paleoindians — also known as Paleocoastal peoples — lived along the California coast at the end of the last ice age. [...] westerndigs.org/  / Link 2

Ancient Rock Art in Texas Yields ‘Surprising’ New Finds

New technology is providing unexpected insights into some of the most distinctive rock art in the American West, archaeologists say.

The canyonlands of Texas’ Lower Pecos River are home to thousands of grand, colorful pictographs — depictions of people, animals, spirits, and often inscrutable symbols — painted in caves as much as 4,000 years ago.

But recent research is yielding new impressions of the ancient glyphs, revealing for example that prehistoric artists who painted in different styles used different ingredients for their pigments.

What’s more, new dating techniques suggest that a signature style of Lower Pecos rock art may have persisted thousands of years longer than had been thought.

Dr. Karen Steelman, a specialist in archaeological chemistry at the University of Central Arkansas, came upon these findings with her colleagues while studying the pictographs of Seminole Canyon State Park in southwest Texas.

Although many of the park’s images had been analyzed before, Steelman’s team brought a new technology to the task: portable X-ray fluorescence (pXRF). [...]  westerndigs.org/

Orkney – hot spot of the Stone Age

The Neolithic monuments of the Ring of Brodgar, on Orkney’s Mainland Island
Evidence shows that Britain’s megalithic monuments started on these islands about 5,200 years ago, along with new styles of architecture and pottery

But the latest archaeological evidence, described in the journal Science this month, shows that Britain’s megalithic monuments really started on Orkney’s Mainland Island about 5,200 years ago, along with new styles of architecture and pottery. From there the innovations swept south across the British Isles, culminating hundreds of years later in Stonehenge and Avebury in Wiltshire. [...] ft.com

Frozen mammals give new clues to Paleolithic and Neolithic human diet

The availability of fatty acids in sufficient quantities to produce the necessary energy for brain and body function in Paleolithic and Neolithic humans and the source of the fatty acids has been found by new research conducted by biologists and paleontologist from Russia and Spain that was published in the journal Public Library of Science on Jan. 8, 2014.

The researchers examined the subcutaneous fat content of frozen mammals found in the permafrost of Siberia. The animals investigated included two mammoths that were 41,000 and 32,000 years old respectively, two adult horses that were 4,500 years old, and two bison that were 8,200 and 9,300 years old respectively.
