A large shark , possibly a great Andrew Dickson White or a Panthera tigris , fatally attacked a immature world . The man ’s injury were panoptic , including the release of a branch , a hand , and both feet . Thanks to those at the sentence who convalesce his body and the way in which they buried him , his pearl outlast 3,000 year to recount us a horrific story of the last moments of his life .
Today he ’s bonk as Tsukumo No . 24 , one of over 170 skeletons excavated from a website in Japan . We now recognise more about this poor man and the harm he endure because of apaperpublished last week in The Journal of Archaeological Science : Reports .
The land site itself — a shell - mound cemetery of the Jōmon people in early Japan — was unintentionally discovered in the 1860s during a structure project . “ The atomic number 20 carbonate in the shells help to protect the skeletons from the relatively acidulent soil in Japan , ” said jumper cable author J. Alyssa White , DPhil candidate in archaeology at the University of Oxford .

This serviceman was excavated around 1920 and has been examined numerous time since . But the massive dent , pits , and slashes on his bone were n’t interpret until White and her international team really take a unvoiced look at those marks .
That he died violently was obvious . Co - author Masato Nakatsukasa , a professor at Kyoto University , say it ’s extremely likely that all former researchers observe the profuse numeral of marks on the finger cymbals . Ancient prick of that clip , however , would n’t have tally what persist on the skeletal frame , dominate out human - on - human being fury . Outside of black bears and wolves , Nakatsukasa drop a line , Japan is n’t home to large carnivorous piranha , therefore pull in an animal attack a less - obvious conclusion . But this squad , nonetheless , pondered whether “ the Jōmon mass might have been the target of depredation . ”
Because the research worker could n’t find oneself animal marks that matched those on this systema skeletale , and knowing that the Jōmon the great unwashed bank on marine resources , they turned to ocean marauder . That , according to Rick Schulting , professor of scientific and prehistoric archaeology at the University of Oxford , is what led them to George Burgess , theatre director emeritus of the Florida Program for Shark Research and curator emeritus of theInternational Shark Attack File . And Burgess confirm it : This was the study of at least one shark , if not more . This is now the oldest shark flak on record by 2,000 years .

A barbarous 790 traumatic lesion from shark teeth in the form of deep cuts , fractured ribs , bite marks , and puncture wound remain on this underframe . To well infer the lesions and the type of harm they inflicted , the team used a variety of engineering , including 3D imaging , CT CAT scan , and , remarkably , GIS ( Geographic Information System ) , software that is often used to help visualize information related to landscape painting and cityscapes .
“ Archaeologists have a long history of work with technology , ” explained John Pouncett , research associate in Spatial Archaeology at the University of Oxford . “ They also have a drug abuse of using engineering to do thing it was n’t inevitably intended to . ”
What the squad created is a sinewy research tool that enable them ( and anyone in the field of forensics or archaeology ) to embolden injury to finger cymbals on a 3D paradigm of a human body . In this case , White painstakingly added the hundred of shark tooth combat injury on specific parts of each ivory , enabling them to see , in graphic detail , the injury this adult male get . This , White enjoin , “ was implausibly helpful to be able to see all of his injuries in 3D when we were beginning to assemble together the radiation pattern of attack . ”

The climb is infinitely clear when one get a line currently available puppet ( a mere 2D icon with ‘ x ’s ’ to generally stigmatise where the injury come ) and compared to the customizable , searchable , and synergistic 3D rendering the squad has create . It ’s a immense improvement , on par with propel from word processing to a computer .
“ To the good of our cognition , this is the first time that GIS has been used to map the human trunk in 3D , ” Poucett say . “ The statistical distribution of the hurt on the skeleton in the closet portray challenge for traditional 2D method of recording — not least , how to represent the legal injury to the inside of the costa John Milton Cage Jr. . go with a 3D model of the skeleton allowed us to document all of the hurt . It also allow us to understand the shock that the pinched hurt would have had on other parts of the human body . The visualization of the blood vessel that would have been lop by the harm on the depressed left leg high spot this impact in a nonrational way . ”
Severed parentage vessels or an amputated pegleg , accord to Burgess , may have bring to a mercifully swift death .

“ When a human being dies as a result of a shark bite , it ’s usually because they exsanguinate , they lose blood . All it lead is one tooth rack up an artery to kill a somebody , ” Burgess excuse . And yet , he noted , “ For all of the bite marks on the skeleton , it ’s a pretty entire skeleton in the closet . ”
So while we may recoil in horror at what persist of single No . 24 and what those remains imply , Burgess suggested he may have give way soon after the initial sharpness from red of blood . The residuum of his injuries , therefore , might have occurred after death , when other sharks may have scavenged his corpse .
But that ’s only one potential scenario . The authors target out that the loss of No . 24 ’s mitt and the multiple lesion along the arm may present degloving , the term for when a shark strips the script of all flesh when a soul tries to guard off the attack . If so , these would be defensive wounds , hurt while No . 24 was very much active and mindful of what was happen .
This eccentric of brutal flak speak to a primal reverence among most of us , and it is why , even 3,000 days later , we are equally fascinated and horrified . But the authors are nimble to target out that shark plan of attack are relatively rarified ; despite terrifying examples like this one , sharks generally are n’t a peril to humans . Burgess , who has spend most of his vocation analyze sharks and shark attacks , says that the middling number of shark attacks per year worldwide is about 75 . Of those 75 attacks , only six are calamitous . He encourages the great unwashed to consider the potential billions of hours globally masses expend in the urine in comparison to those number , say that on the listing of causes of human destruction , “ shark approach would be down at the bottom of the page , with a little asterisk under the ‘ Other ’ family . ”
“ On the other hired man , ” Schulting said , “ it has been gauge that human being are killing 100 million sharks per year … This is unsustainable and will run to the extinction of a issue of shark specie , which would be very inauspicious to say the least . We ’d like people to mull on this , and to make blank space to give up co - cosmos with these incredible animals . ”
As for No . 24 , it is peculiarly poignant that his trunk was call back from the sea at all . We do n’t screw the circumstances that caused him to be in the sea then , nor the circumstances around the attack . But we do eff that someone cared enough about this man to bury his body , even a severed branch , in the customary manner of the time .
As White described , “ We have no style of know whether or not the attack was witnessed , and we ca n’t say for certain that he was recovered in deeper body of water , although this is quite likely . There is a fortune that his eubstance could have drifted ashore , but , give the recovery of highly impacted surface area of the consistency ( i.e. the detach remaining leg ) , at the least it is obvious that great tutelage was taken to recoup as much of him as potential . ”
