Application of the Blue-Intensity Method for Dating Wooden Buildings in Siberia

Despite the success achieved in the tree-ring dating of wood samples from archaeological excavations over the recent years, attempts to apply this method to relatively recent wooden constructions in central Siberia run into considerable difficulties, because the increment of wood in that area shows little variation due to the virtual absence of limiting factors. To solve this problem, we used the blue intensity method, based on measuring the optical density of wood. This method is more sensitive to environmental changes of annual growth rates and is optimal in terms of efficiency and cost. This article describes the techniques of sample preparation, measuring optical density of annual rings, and the construction of chronologies based on this indicator. The efficiency of the method is assessed by comparing it with the traditional approach based on tree-ring width for dating wood from the temperate zone of Siberia. Results of dating two wooden structures the Gromov house and the Gafarov store indicate the efficiency of the new method virtually without limiting factors affecting increment rates. Cook E.

Two men found at the Yana Rhinoceros Horn Site in northern Siberia in Russia date to about 32, years ago, providing the earliest direct evidence of humans in the region. Indigenous Americans, who include Alaska Natives, Canadian First Nations, and Native Americans, descend from humans who crossed an ancient land bridge connecting Siberia in Russia to Alaska tens of thousands of years ago.

It was cold, remote and involved picking fights with woolly mammoths — but it seems ancient Siberia 30, years ago was home to a hardy and previously unknown group of humans. Scientists say the discovery could help solve longstanding mysteries about the ancestors of native North Americans. While it is commonly believed the ancestors of native North Americans arrived from Eurasia via a now submerged land bridge called Beringia, exactly which groups crossed and gave rise to native North American populations has been difficult to unpick.

Writing in the journal Nature , Eske Willerslev and colleagues reveal how they drew on existing data from modern populations as well as analysing ancient DNA from the remains of 34 individuals obtained from sites around north-eastern Siberia, dating from more than 31, years ago up to years ago. The key remains were fragments of two tiny human milk teeth, shed by males, found at a place in Russia called Yana Rhinoceros Horn Site.

First excavated in , the site offers the earliest direct evidence of humans in north-eastern Siberia, with finds also including bone items and stone tools. Indirect evidence of human populations in north-eastern Siberia goes back to more than 40, years ago. While it had previously been thought that these remains might be from the ancestors of native North Americans, the DNA data suggests otherwise. The results reveal these individuals were part of a previously unknown yet widespread group, dubbed the Ancient North Siberians by the team, who were genetically distinct from both Western Eurasians and East Asians.

The researchers say they split off from the former 38, years ago — in other words, very shortly after Western Eurasians and East Asians themselves became genetically distinct. But, crucially, this population does not appear to be the direct ancestor of Native Americans. Instead, analysis of the collection of genomes suggests the population that became the ancestors of native North Americans was the result of liaisons about 20, years ago between East Asians, who travelled north, and a group distantly related to the Ancient Northern Siberians.

The East Asians also mixed with other descendants of Ancient Northern Siberians to give rise to another group, who the team dub the Ancient Paleo Siberians, who went on to supplant the existing group. The team add that one possibility is that the mixing involving the East Asians occurred in southern Beringia — one of the areas that could have offered respite from harshening conditions at the time.

Domestication as Enskilment: Harnessing Reindeer in Arctic Siberia

Please refresh the page and retry. A n 18,year-old puppy unearthed in Siberia could prove to be the missing link between dogs and wolves , scientists believe. The puppy was discovered perfectly preserved by permafrost near Yakutsk, eastern Siberia last summer and carbon dating has revealed it has been frozen for around 18, years. Researchers at the Centre for Palaeogenetics in Stockholm, Sweden announced this week that extensive DNA tests have so far been unable to confirm whether the animal was a dog or a wolf.

The experts believe this may be because the canine comes from the period when dogs were domesticated and hope the creature will prove crucial to uncovering when exactly the evolution began. The fact that we can’t might suggest that it’s from a population that was ancestral to both – to dogs and wolves”.

Yet, despite its size, it has around half the total population of the UK. Amur Tiger. The king of Siberian wildlife, the Amur tiger is a solitary animal hidden deep within the woodlands and birch forests of the Siberian heartlands. Amur tigers have been hunted near to extinction on several occasions, with only 40 reported to remain in the s. In the last few decades measures have been taken to protect these majestic animals and Russia has since granted the species full protection which has seen numbers rise considerably.

Amur tigers have been known to grow up to 10 feet in length and can weigh up to an impressive kg. Eurasian Lynx. A majestic and capable predator said to wander the forest-steppes, the Eurasian lynx is renowned for its ability to adapt to its surroundings. This lynx has been known to subtly change it colourings from a short reddish-brown coat is temperate climates to a long silky greyish coat during the Winter.

Newly sequenced genomes from prehistoric hunter-gatherers in the region of Lake Baikal reveal connections with First Americans and across Eurasia. Using human population genetics, ancient pathogen genomics and isotope analysis, a team of researchers assessed the population history of the Lake Baikal region, finding the deepest connection to date between the peoples of Siberia and the Americas.

The current study, published in the journal Cell , also demonstrates human mobility, and hence connectivity, across Eurasia during the Early Bronze Age.

In , a ‘royal’ burial site in Tuva Republic, Siberia, dating to early The early date of these finds, demonstrated by a combination of radiocarbon and.

Oxford University scientists have played a key role in new research identifying the earliest evidence of some of the first known humans — Denisovans and Neanderthals, in Southern Siberia. Professor Tom Higham and his team at the Oxford Radiocarbon Accelerator Unit at the University of Oxford worked in collaboration with a multi-disciplinary team from the UK, Russia, Australia, Canada and Germany, on the detailed investigation over the course of five years, to date the archaeological site of Denisova cave.

Situated in the foothills of Siberia’s Altai Mountains, it is the only site in the world known to have been occupied by both archaic human groups hominins at various times. The two new studies published in Nature , now put a timeline on when Neanderthals and their enigmatic cousins, the Denisovans, were present at the site and the environmental conditions they faced before going extinct. Denisova cave first came to worldwide attention in , with the publication of the genome obtained from the fingerbone of a girl belonging to a group of humans not previously identified in the palaeoanthropological record; the Denisovans.

Further revelations followed on the genetic history of Denisovans and Altai Neanderthals, based on analysis of the few and fragmentary hominin remains. Last year, a bone fragment discovered by researchers at Oxford’s Research Laboratory for Archaeology and the History of Art and the University of Manchester, yielded the genome of the daughter of Neanderthal and Denisovan parents — the first direct evidence of interbreeding between two archaic hominin groups.

But reliable dates for the hominin fossils recovered from the cave have remained elusive, as have dates for the DNA, artefacts, and animal and plant remains retrieved from the sediments. In the new research, the Oxford team obtained fifty radiocarbon ages from bone, tooth and charcoal fragments recovered from the upper layers of the site, as part of the ERC funded ‘PalaeoChron’ project.

In addition to these, more than optical ages were obtained for the cave sediments, most of which are too old for radiocarbon dating, by researchers at the University of Wollongong in Australia.

In this short note, we report new age determinations from four samples of the Middle-Paleozoic Viluy Traps in Siberia, east of the more famous Permo-Triassic Siberian Traps. Dating these samples as a concerted effort in two independent laboratories working jointly on their interpretation is a rather rare yet very valuable exercise. With the K-Ar technique, ages ranging from to Ma with uncertainties on the order of 5 Ma were obtained.

Three out of four ages yielded by the two separate methods are in agreement within uncertainties. One sample yields incompatible ages and could be from a later, altered dyke event. These results underscore a need for further work, in progress. C Elsevier B. All rights reserved.

The early history of Siberia was greatly influenced by the sophisticated nomadic civilizations of the Scythians Pazyryk on the west of the Ural Mountains and Xiongnu Noin-Ula on the east of the Urals, both flourishing before the Christian era. The steppes of Siberia were occupied by a succession of nomadic peoples, including the Khitan people , [ citation needed ] various Turkic peoples , and the Mongol Empire. During the Russian Empire , Siberia was chiefly developed as an agricultural province.

The government also used it as a place of exile, sending Avvakum , Dostoevsky , and the Decemberists , among others, to work camps in the region. During the 19th century, the Trans-Siberian Railway was constructed, supporting industrialization.

Abstract he North Taymyr ice-marginal zone NTZ is a complex of glacial, glaciofluvial and glaciolacustrine deposits, laid down on the northwestern Taymyr Peninsula in northernmost Siberia, along the front of ice sheets primarily originating on the Kara Sea shelf. It was originally recognised from satellite radar images by Russian scientists; however, before the present study, it had not been investigated in any detail.

The ice sheets have mainly inundated Taymyr from the northwest, and the NTZ can be followed for km between 75 degrees N and 77 degrees N, mostly km inland from the present Kara Sea coast. The ice-marginal zone is best developed in its central parts, ca. In two of these, the ice sheet ended on land, whereas in the two others, it mainly terminated into ice-dammed lakes. The base of the NTZ is a series of up to m-high and 2-km-wide ridges, usually consisting of redeposited marine silts.

These ridges are still to a large extent ice-cored; however, the present active layer rarely penetrates to the ice surface.

Ancient-human species mingled in Siberia’s hottest property for 300,000 years

With its light-filled main gallery and sweeping views of the Altai Mountains of southern Russia, Denisova Cave was a Stone Age version of a Manhattan penthouse. Overlooking the Anui River, where herds of animals came to drink, it offered an unparalleled vantage for spotting game and other humans, as well as refuge from Siberian storms.

Generations of Neanderthals, their Denisovan cousins, and modern humans enjoyed the view. But when did each group reside there? The timing could yield clues to how these diverse humans interacted and shed new light on the most enigmatic of the three, the Denisovans, who are known only from DNA and scrappy fossils from this cave.

CNN Scientists studying the remarkably well-preserved remains of an Ice Age bird have identified the specimen as a horned lark. Chat with us in Facebook Messenger. Find out what’s happening in the world as it unfolds. The 46,year-old specimen was identified as a horned lark. Radiocarbon dating revealed the bird lived around 46, years ago, and genetic analysis identified it as a horned lark Eremophila alpestris , according to a paper published Friday in the journal Communications Biology.

The bird was found in north-eastern Siberia at a site which also contained other frozen specimens. Read More. The preservation of the bird is explained in large part by the cold of the permafrost, explained Dussex, but this specimen is in extraordinarily good condition. Is it a dog or is it a wolf? Scientists working in the area have also found carcasses and body parts from other animals such as wolves, mammoths and wooly rhinos.

Dussex described such findings as “priceless” as they allow researchers to retrieve DNA and sometimes RNA, a nucleic acid present in all living cells. Using carbon dating on the creature’s rib bone, experts were able to confirm that the specimen had been frozen for around 18, years, but extensive DNA tests have so far been unable to show whether the animal was a dog or a wolf.

The problem of absolute dating of Siberia’s Quaternary geomorphological complexes

The race is on to save astonishing treasures from a Russian ‘Atlantis’ which has risen from the depths of a vast made-made lake in Siberia. By early July, the water will rise and cover the graves up to 50 ft 15m deep water, frozen in winter, until it retreats again briefly next summer. Especially rich in finds are necropolises from an era when an ancient Hun population held sway around 2, years ago.

Pictured: a grave uncovered at the site. Water at the reservoir retreats for a few weeks each summer, letting archaeologists examine the graves of long dead civilisations that called the site home.

Official websites use. Share sensitive information only on official, secure websites. By: Steven M. A suite of new accelerator-mass spectrometer AMS radiocarbon ages provides the first reliable chronology for late Quaternary sediments in Lake Baikal. In this large, highly oligotrophic lake, biogenic and authigenic carbonate are absent, and plant macrofossils are extremely rare. Total organic carbon is therefore the primary material available for dating. Several problems are associated with the TOC ages.

One is the mixture of carbon sources in TOC, not all of which are syndepositional in age. This problem manifests itself in apparent ages for the sediment surface that are greater than zero. The other major problem with dating Lake Baikal sediments is the very low carbon contents of glacial-age deposits, which makes them extremely susceptible to contamination with modern carbon.

This problem can be minimized by careful sampling and handling procedures.
