We have thousands of examples of Ice Age works from Europe — curvy Venus figurines , pearl carved from bone , and cave paintings of saber - toothed computerized tomography and mammoth dating back some 35,000 years . Those site are also the best documented in the populace , having been study since the 19th century .
grounds of the early art on other continents is much more scant , but it ’s increasingly beingrecordedacross the world . In the latest field that attempts to offer a more complete picture of human creativity , researchers report that they ’ve discovered jewelry and pigments inside of an Ice Age cave in Indonesia that are between 22,000 and 30,000 old age old . They published theirfindingstoday in theProceedings of the National Academy of Sciences .
ArchaeologistAdam Brummand his workfellow have been essay traces of the early dweller of Sulawesi . The island is form a bit like a withered starfish and it ’s the biggest in Wallacea , the region between the Asian and Australian continental shelves .
The investigator made headline in 2014 when they discovered [ PDF ] that cave graphics among the hulk karst formations on Sulawesi ’s southwesterly peninsula could be among the one-time in the creation . Using a accurate dating method , they document mitt stencil that are about 40,000 years old . They also found a figurative painting of a pig - deer ( or babirusa ) that was more than 35,000 years quondam , match the age of the brute paintings inside France ’s famousChauvet Cave .
As detailed in the current survey , the archaeologists excavated the floor of another cave known as Leang Bulu Bettue .
“ We started turn over at this limestone cave because it was the only site I had date in the region which seemed to have escaped the ravages of erosion and disturbance from local farmers digging up the guano - copious cave earth for use as fertilizer , ” Brumm , who is an associate professor at Griffith University in Australia , tell mental_floss . The cave also had rock music art maintain on its walls and ceiling — red and imperial hand stencils that are identical to some of the nearby cave painting discover in 2014 .
So , the investigator mistrust they would find some undisturbed archeologic deposit — and indeed they did .
They dug up stone artifacts chip at with geometric patterns like Xs and parallel line , as well as chunks of ochre , a natural pigment that was used in cave house painting . They unearthed a perforated finger’s breadth bone from a local bear cuscus , a kind of marsupial , that was peradventure used for a necklace , and they found bare magnetic disk - shape drop made from a babirusa tooth . The artifacts date to between 22,000 and 30,000 years ago .

Brumm says that of Wallacea ’s 2000 island , only seven have so far ease up archaeological sedimentation from the Pleistocene , the era when the last Ice Age occurred . Therefore , the full numeral of artifacts from the region is “ pitifully small , ” he says , perhaps numbering only a dozen or so .
“ This profound asymmetry in enquiry intensity level make it extremely difficult to depict meaningful compare between the ‘ Ice Age ’ cultures of Wallacea and Europe , ” Brumm says .
The fact that the fresh discovered artifacts were made from the bone of animate being that are only discover on Sulawesi suggests that former humans were “ imbibe to the symbolic potential of the alien species they encountered ” when they colonize this part , Brumm says .
“ This speaks of a flexibility in early human refinement in this niggling understood part of the ‘ Ice Age ’ world — an ability to accommodate existing art anatomy and emblematical finish to entirely raw environments and ecosystems , ” Brumm adds . And he think it ’s exactly this kind of flexibleness that would have tolerate people from this area to colonise an isolated continent like Australia around 50,000 years ago .
ArchaeologistIain Davidson , an emeritus professor at the University of New England in Australia , who was n’t involve in the study , likewise thinks the same attainment that let people to make vessel and navigate across Wallacea “ should have enable them to represent their humans symbolically . ”
Davidson calls the discovery very important " primarily because it adds to the emerging picture of an early rock art man in the region where there has been thought to be none ; now it is clear that there is , ” Davidson tells mental_floss . “ It was always potential , but maybe only a matter of looking and using the appropriate technique , which is what this team has done really well . ”
