An fine decorated 7,500 - year - one-time antler from central Sweden was first used as a battle ax and afterward belike as a fishing harpoon during the Stone Age , a newfangled study suggests .
Researchers regain the antler eight years ago , but had not been able to hit the books it with fresh technology until now .
Different views of the richly decorated antler from Sweden. Archaeologists think it was first used as a battle ax and later as a harpoon.
" It was likely handle as an ax , " cogitation co - authorLars Larsson , a professor of archaeology at Lund University in Sweden , told Live Science . " There are several examples in present - day Denmark of antler axes with severe damage after labored use . " The damage intimate the axes were used in struggle , he said .
The antler was originally discovered atop a rock platform in a river running from Lake Vättern to the Baltic Sea . It was lodge alongside several other items , including a off-white needle , fishing barbs , stone axe blades , engraved creature bones and 20 composition of human skull . The little cache was discover at the archaeological site of Strandvägen , a village from the Mesolithic , or Middle Stone Age .
" The Strandvägen site is one of the largest Mesolithic sites in Sweden , and unique in the region as preservational setting generally are poor in this region,“Sara Gummesson , an archeologist at Stockholm University in Sweden who was not involve in the subject area , told Live Science .

Because of the extremely acidic dirt in Sweden , constitutive materials typically put down , forget no suggestion . Strandvägen is exceptional in that it put up one of the few areas where organic cloth like antler has been preserved . This preservation is in part because many of the constituent cloth were found in water , but also because the dirt are in a basics that is less acidic , Gummesson said .
Pastradiocarbon datingof bones and artefact at Strandvägen has read that the region was inhabited from 5,800 to 5,000 B.C. The settlement is across the river from another important site , calledKanaljorden , which was occupied around the same metre and has revealed unparalleled discovery such as head impaled on wooden stakes .

" The liquidation is turn up next to the only outlet for Lake Vättern , Sweden ’s secondly tumid lake , " Larsson say . Groups of huntsman - fisherman - accumulator thrived around this outlet of the lake , using nearby forests for hunt and the lake for fishing , he say .
Prior excavations at Strandvägen revealed graves , houses , workshops and legion bone and antler tools , but this antler is the " best - decorated " of the pearl and antler objective , Larsson said .
The antler , which comes from a red deer ( Cervus elaphus ) , measures around 4.2 inches ( 10.7 cm ) long and has a width of 0.8 inch ( 2.1 cm ) . carbon 14 geological dating of tar base within the antler ’s grooves suggests it is around 7,500 yr old .
From ax to harpoon
To better infer the antler and its account , Larsson and his co - source , Fredrik Molin , an archaeologist at Sweden ’s National Historical Museum , analyse it with a digital microscope .
Their analysis disclose that the antler was ab initio file to produce even surfaces before it was carved with a obdurate tool to create elaborate crosshatch - like patterns . Tar was then rubbed into the etched groove to accentuate the hatchlike invention .
It come along that multiple masses worked on the antler , with some of the patterns appearing less precise and having been pare down to make way for new conception . Some of the craftsman appear to have been more skilled than others .
Antlers serve as handle that were attached to sharpened bones or stone blades , and they showed characteristic breakage when overdrive . This antler has that breakage formula , suggesting that the decorated antler was probably used as an ax in engagement , Larsson said .
Further atomization on the antler conduct Larsson and Molin to believe the ax may have been repurposed into a harpoon , which is another common artefact find across the site .

Nowadays , " if an item gets broken , many of us buy a new one , " Gummesson said . " This was not the case until very recently . "
The concluding burying of the antler alongside other respect good and human remains suggests the antler was finally buried as a sacrifice .
" An physical object may actually have changed habit , been given new values , repaired and cherish in many dissimilar way throughout its ' spirit ' , which also may have extended beyond one individual ’s lifetime , " says Gummesson .
