Dating back 40,000 years to the Denisovan species of early humans, new pictures show beauty and craftsmanship of prehistoric jewellery.

It is intricately made with polished green stone and is thought to have adorned a very important woman or child on only special occasions. Yet this is no modern-day fashion accessory and is instead believed to be the oldest stone bracelet in the world, dating to as long ago as 40,000 years.
Unearthed in the Altai region of Siberia in 2008, after detailed analysis Russian experts now accept its remarkable age as correct. 

New pictures show this ancient piece of jewellery in its full glory with scientists concluding it was made by our prehistoric human ancestors, the Denisovans, and shows them to have been far more advanced than ever realised.
'The bracelet is stunning - in bright sunlight it reflects the sun rays, at night by the fire it casts a deep shade of green,' said Anatoly Derevyanko, Director of the Institute of Archaeology and Ethnography in Novosibirsk, part of the Siberian Branch of the Russian Academy of Sciences.

'It is unlikely it was used as an everyday jewellery piece. I believe this beautiful and very fragile bracelet was worn only for some exceptional moments.'
The bracelet was found inside the famous Denisova Cave, in the Altai Mountains, which is renowned for its palaeontological finds dating back to the Denisovans, who were known as homo altaiensis, an extinct species of humans genetically distinct from Neanderthals and modern humans.
Made of chlorite, the bracelet was found in the same layer as the remains of some of the prehistoric people and is thought to belong to them.
What made the discovery especially striking was that the manufacturing technology is more common to a much later period, such as the Neolithic era. Indeed, it is not clear yet how the Denisovans could have made the bracelet with such skill.

Writing in the Novosibirsk magazine, Science First Hand, Dr Derevyanko said: 'There were found two fragments of the bracelet of a width of 2.7cm and a thickness of 0.9 cm. The estimated diameter of the find was 7cm. Near one of the cracks was a drilled hole with a diameter of about 0.8 cm. Studying them, scientists found out that the speed of rotation of the drill was rather high, fluctuations minimal, and that was there was applied drilling with an implement - technology that is common for more recent times.

'The ancient master was skilled in techniques previously considered not characteristic for the Palaeolithic era, such as drilling with an implement, boring tool type rasp, grinding and polishing with a leather and skins of varying degrees of tanning.'
Chlorite was not found in the vicinity of the cave and is thought to have come from a distance of at least 200km, showing how valued the material was at the time.
Dr Derevyanko said the bracelet had suffered damage, including visible scratches and bumps although it looked as if some of the scratches had been sanded down. Experts also believe that the piece of jewellery had other adornments to make it more beautiful.
'Next to the hole on the outer surface of the bracelet can be seen clearly a limited polished zone of intensive contact with some soft organic material,' said Dr Derevyanko. 'Scientists have suggested that it was a leather strap with some charm, and this charm was rather heavy. The location of the polished section made it possible to identify the 'top' and 'bottom' of the bracelet and to establish that it was worn on the right hand.'

Located next to the Anuy River, about 150 km south of Barnaul, the Denisova Cave is a popular tourist attraction, such is its paleontological importance. Over the years a number of remains have been found there, including some of extinct animals such as the woolly mammoth. In total evidence of 66 different types of mammals have been discovered inside, and 50 bird species.
The most exciting discovery was the remains of the Denisovans, a species of early humans that dated back as early as 600,000 years ago and were different to both Neanderthals and modern man.
In 2000 a tooth from a young adult was found in the cave and in 2008, when the bracelet was found, archaeologists discovered the finger bone of a juvenile Denisovan hominin, whom they dubbed the 'X woman'. Further examination of the site found other artifacts dating as far back as 125,000 years.
The institute's deputy director Mikhail Shunkov suggested that the find indicates the Denisovans - though now extinct - were more advanced than Homo sapiens and Neanderthals.

'In the same layer, where we found a Denisovan bone, were found interesting things; until then it was believed these the hallmark of the emergence of Homo sapiens,' he said. 'First of all, there were symbolic items, such as jewellery - including the stone bracelet as well as a ring, carved out of marble.'
The full details of the ring are yet to be revealed. 
'These finds were made using technological methods - boring stone, drilling with an implement, grinding - that are traditionally considered typical for a later time, and nowhere in the world they were used so early, in the Paleolithic era. At first, we connected the finds with a progressive form of modern human, and now it turned out that this was fundamentally wrong. Obviously it was  Denisovans, who left these things.'
This indicated that 'the most progressive of the triad' (Homo sapiens, Homo Neanderthals and Denisovans) were Denisovans, who according to their genetic and morphological characters were much more archaic than Neanderthals and modern human.'

But could this modern-looking bracelet have been buried with older remains?
The experts considered this possibility but rejected it, saying they believe the layers were uncontaminated by human interference from a later period. The soil around the bracelet was also dated using oxygen isotopic analysis.
The unique bracelet is now held in the Museum of History and Culture of the Peoples of Siberia and the Far East in Novosibirsk. Irina Salnikova, head the museum, said of the bracelet: 'I love this find. The skills of its creator were perfect. Initially we thought that it was made by Neanderthals or modern humans, but it turned out that the master was Denisovan, at least in our opinion.

'All jewellery had a magical meaning for ancient people and even for us, though we do not always notice this. Bracelets and neck adornments were to protect people from evil spirits, for instance. This item, given the complicated technology and 'imported' material, obviously belonged to some high ranked person of that society.'
While bracelets have been found pre-dating this discovery, Russian experts say this is the oldest known jewellery of its kind made of stone.

How to Digitally Record/Video a UFO sighting:


Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:




Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
