About 200,000 year ago , ice age children splash their hand and foot into awkward clay thousands of foot above sea level on the Tibetan Plateau . These picture , now maintain in limestone , provide some of the early evidence of human ancestors inhabit the expanse and may lay out the oldest fine art of their kind ever discovered .
In a new account , release Sept. 10 in the journalScience Bulletin , the study authors indicate that the hand and footprints should be consider " parietal " art , mean prehistorical art that can not be displace from place - to - position ; this usually refers to petroglyphs and paintings on cave wall , for instance . However , not all archaeologists would fit that the newfound print meet the definition of parietal artwork , an expert told Live Science .
This 3D-relief model shows fossilized hand and footprints with colors depicting the depth of the prints within the surrounding rock.
Traces left by ice age children
Study generator David Zhang , a prof of geography at Guangzhou University inChina , first pick out the five handprints and five footprints on an military expedition to afossilhot leaping at Quesang , place more than 13,100 foot ( 4,000 meter ) above sea point on the Tibetan Plateau . The authors see the sample by tax how much uranium , a radioactive element establish by nature in the environment , could be found in the prints . Based on the rate at whichuraniumdecays , they reckon that the picture were bequeath about 169,000 to 226,000 years ago — smack tap in the middle of thePleistocene epoch , which pass off 2.6 million to 11,700 long time ago .

And guess by the sizing of the prints , the team determined that the marks were bequeath by two children , one about the sizing of a innovative - day 7 - year - former and the other the size of a 12 - year - old . That order , the team ca n’t be indisputable what mintage of archaichumansleft the print , said study carbon monoxide gas - author Matthew Bennett , a prof of environmental and geographic sciences at Bournemouth University in Poole , England .
Here, some of the hand and footprints are preserved in limestone on the Tibetan Plateau.
" Denisovans are a material possibility , " butHomo erectuswas also jazz to inhabit the region , Bennett told Live Science , refer to a couple of sleep with human ascendent . " There ’s lots of contenders , but no , we do n’t really make love . "
The prints supply the early evidence of hominins at Quesang , " but there is growing grounds of primitive humans being around the Tibetan Plateau at a similar clock time , " Bennett added . For example , scientist lately recovered a Denisovan lower jawbone in the Baishiya Cave , located at the northeastern edge of the Tibetan Plateau , said Emmanuelle Honoré , a postdoctoral inquiry fellow at the Université Libre de Bruxelles in Belgium , who was not affect in the study . The mandible is " at least " 160,000 years old , researchers reported in 2019 in the journalNature , meaning the bone remnants could date back to the same period as the Quesang handprints , Honoré told Live Science in an email .
That order , the Baishiya Cave lie many mile north of Quesang and sit at only 10,500 feet ( 3,200 m ) above sea grade , so the newfound handprints supply the oldest grounds of occupation in the central , highest - elevation region of the plateau , say Michael Meyer , an assistant professor of geology at the University of Innsbruck in Austria , who was not involved in the cogitation . Like the discipline author , Meyer suspects that Denisovans probably left the handprints , so " the report could thus argue that Denisovans were the first Tibetans and that they originally adapted genetically to cope with the eminent - elevation stress , " he told Live Science in an email .
Here, some of the hand and footprints are preserved in limestone on the Tibetan Plateau.
The handprints themselves are made of travertine , a sort of freshwater limestone take form by mineral alluviation from natural springs . When first deposit , travertine forms a " very fine , sludgy mud , " which one can easily push their hands and foot into , Bennett say . Then , when snub off from H2O , the travertine hardens into gemstone .
On a previous expedition , transmit in the eighties , Zhang uncovered similar hand and footprint near a advanced hot spring bathhouse at Quesang , and in general , many traces of early man can be found decorate the slopes nearby . Those previously bring out hand and infantry impression vary in size , imply that they were go forth by children and adults , but they come along to have been made organically as people made their way over the land . The newfound prints , on the other helping hand , take issue in that they appear to have been left deliberately , Bennett aver .
" They ’re deliberately placed … you would n’t needs get these traces if you were doing normal activities across the gradient , " he tell . " They ’re actually positioned within the place , as if somebody was , you know , making a more measured theme . " Bennett compared the prints to finger flutings — a kind of prehistoric art made by people running their fingers over indulgent surfaces on cave walls . Both children and adults are think to have take part in finger fluting , and similarly , Bennett said that the Quesang mark should also be considered art .

To suck up a comparison to modern meter , " I ’ve got a 3 - year - sure-enough daughter , and when she does a scribble , I put it on the fridge … and say it ’s art , " Bennett said . " I ’m sure that an artistic creation critic would n’t necessarily define my child ’s scribble as art , but in general utilization , we would do [ so ] . And this is no dissimilar . "
Work of art?
If the Quesang prints modify as parietal art , they would be the oldest known example of the musical style yet discovered , the author noted in their theme . Previously , the oldest known examples of parietal art were handwriting motif and hand stencils found on the Indonesian island of Sulawesi and in the El Castillo cave in Spain , which both day of the month between about 45,000 and 40,000 years old .

However , " Quesang has little to do with those two internet site , except for the fact that they are all three displaying hand [ and ] footprints , " Honoré told Live Science . " leave a print in the mud or doing a stencil print with pigments is a really dissimilar process , not only from a technological point of sight , but also from a conceptual tip of view . "
For Honoré , personally , parietal graphics includes painting and engraving made on rock , but would exclude marking like finger fluting or the Quesang print , and some other archaeologist hold the same panorama . " Regarding fingerbreadth flute , some author consider it already as graphics , others as precursors of art , others as ' experimentation [ or ] play ' rather than art , " Honoré said . " I would personally be among this last category of researchers . "

" Classifying these human traces as art is something that is of only secondary grandness , in my opinion , " Meyer said . The most interesting implication of the young study are that human ancestors interest the high Tibetan Plateau much originally than previously thought , and that rear questions about which species of hominin exit the prints and how they first come to the plateau . look forward , Meyer said he hopes there will be further study to verify the age of the imprints and clarify how they remained so well conserve over time .
Regardless of how contemporary student define the mark , it ’s significant to note that " what we delimitate as art was probably not view with the same oculus by the multitude who made it , " Honoré said . So we may never know what those ancient hominin children were really up to when they press their hands and feet into the hillside , or what their honest-to-god kin might have made of their efforts . For Bennett , though , the fossilized trace of two children play in the mud still count as nontextual matter in his book of account .
