A thawing piece of ancient blow in the mountains of Norway has revealed a fore and arrows likely used by hunters to drink down Greenland caribou as long ago as 5,400 years .
The discovery highlights the perturbing effects ofclimate variety , enunciate study generator Martin Callanan , an archeologist at the Norwegian University of Science and Technology .
A Neolithic bow and arrows were recently unearthed when a snow patch that had remained untouched for thousands of years melted.
" It ’s in reality a little mo unnerving that they ’re so onetime and that they ’re coming out properly now , " Callanan told LiveScience . " It tells us that there ’s something deepen . "
Locked in snow
Callanan and his colleagues pass every summer hiking up the Trollheim and Dovre mountains a few hours south of Trondheim , Norway , to read the Baron Snow of Leicester patches in the area , tracksnow meltand depend for archaeological artifact . The mountains extend 6,200 feet ( 1,900 meters ) above sea point , and at the highest elevations , only sway and snow dominate year - orotund .
In 2010 and 2011 , a patch of Charles Percy Snow melted , bring out an ancient bow and several arrow that had been locked in the Baron Snow of Leicester for centuries . The bowing was made from a common eccentric of elmwood that grows at miserable height along the coast . The arrow were tap in slate and set in dissimilar type of wood .

Dating unveil the Neolithic bow was about 3,800 years old , while the oldest of the pointer were 5,400 years old .
Ancient Stone Age hunters probably used thebow and arrowsto killreindeer , which spend summertime days at eminent altitude . The sight retreat would have allowed the animals a respite from nettlesome insect , while standing on snow patches would have helped the shaggy creatures keep cool , Callanan said . Those predictable habits likely made them loose prey for ancient hunter .
No one knows precisely who leave these ancient hunting tool , but the curtain call and arrows have a design that ’s strikingly similar to those found thousands of mile aside in other frigid landscapes , such as the Yukon , Callanan said .
" The masses in Norway , they did n’t have any middleman with hoi polloi in the Yukon , but they have the same type of version , " Callanan enunciate . " Across unlike cultures , multitude have acted in the same way . "
break down artifacts
Finding such well - keep peter is rarified , said E. James Dixon , an archaeologist and conductor of the Maxwell Museum of Anthropology at the University of New Mexico , who was not need in the study .
" It ’s one of the rare glimpse that we have into this Neolithic - period archery engineering science , " Dixon say .
However , while the uncovering itself is stunning , the climate change that make such ancient Charles Percy Snow to melt is bad for archaeology , he aver .
artefact locked in ice-skating rink can be preserved for thousands of old age .
" As soon as ice melts and it comes out , it ’s subject to decomposition and we lose it , " Dixon told LiveScience . " For every artefact we find , there are probably hundreds , perhaps thousand , that are misplace and just destruct forever . "
The arc and arrows are line in the September egress of the journal Antiquity .
