Ancient Scandinavians may have used gravy boat constructed of creature skins to angle , hunt and trade , a new field of study suggest .
Known as the Pitted Ware Culture ( PWC ) , this waterfaring Neolithic chemical group of hunting watch - gatherers live in Scandinavia between 3500 and 2300 B.C. , grant to the subject area , published Aug. 26 in theJournal of Maritime Archaeology .

The radical is perhaps considerably known for its pottery , which features monotone - bottomed vessels stylized with horizontal lines slash into the clay before burn . They were also adept marine hunters , particularly when it come to hunting seals .
Archaeologists remember the PWC may have used the hides of these entanglement - footed aquatic mammal to build up watercraft , as well as oil color from the seals ' fatness to help keep the boats .
" We screw that these people were hunting lots of seals , as evidence by the massive amounts of sealing wax osseous tissue we ’re find oneself at sites that they inhabited , " lead study authorMikael Fauvelle , a researcher in the Department of Archaeology and Ancient History at Lund University in Sweden , told Live Science . " sealskin were also one of the best animals for fix gravy holder , as we know that the Inuit [ an Indigenous group living in Canada , Greenlandand Alaska ] were applying petroleum from seals as a critical pace in waterproofing their boats . We know that the PWC had enceinte quantities of cachet oil , which can be found in their pottery [ at archeologic site ] . "

Access to boats would have been vital to the PWC ’s survival ; the acculturation was reliant on fishing due to live on in an area bounded by several massive bodies of water , including the Baltic and North seas .
" They were proceed across the environment and were trading quite often with other groups , often travel from Gotland [ an island in what ’s now Sweden ] to Åland [ an archipelago to the south ] that is far away , " Fauvelle said . " They would have been out in the ocean , go across big expanse of water . "
Researchers think more primitive boat , such as canoe made from dig - out logs , would have been inefficient in traveling one C of mile across candid water .
" These the great unwashed had to paddle far and wide to hunt , Pisces the Fishes and swap , " Fauvelle said , adding that gravy holder made of seal pelt would have been sturdy enough for the caper .
In fact , the boats — depending on their size — may have been great enough to ravish up to about a XII people at a metre , as well as animals , including deer , bear and cattle , according to the study .

However , the research worker admit that they ’ve ground footling physical evidence of the boats themselves , other than a few modest fragments discovered over the years at sites across northern Sweden that " may represent direct evidence of Neolithic skin gravy boat use , " the authors wrote in the study .
Perhaps the " strongest piece of evidence " is rock’n’roll nontextual matter depicting mass go by sauceboat . Some of the drawings admit details of vessels equipped with harpoon rests that resemble fauna head , Fauvelle said .
" We ’ve found drawings that are comparable to ethnographic skin boats made today and delineation of rectangular gravy holder that are translucent and reveal the rib or fabric of the vessel , " he enounce .
The drawing , coupled with the possible fragments of sauceboat frames , offer evidence that the PWC people were accomplish boat builders who understood " seafaring technology " and would have used " advanced workmanship " to travel between dissimilar island .
" If PWC people did use skin boats , the question remains as to why the engineering science may not have survived into the full point of recorded history , " the authors write .
