In the worlds of extinct elephant coinage and ancient mankind , the science powers that be have granted us a rare twofold curse . Not only have researcher identified the clay of an ancient elephant mintage from some pretty unbelievable fogy , but those fossil have revealed how they might have provided a food source to early humans living in the area .
Theelephant fossilsthemselves were found in 2000 in Pampore in the Kashmir Valley , India , and engagement back to between 300,00 and 400,000 year ago . However , quite which species the fossil belong to , and the fact that humans had been involve with the bone was only discovered latterly .
A unexampled depth psychology has revealed that former humans might have struck the elephant bone to extract the marrow for food – this is a very energy - slow roly-poly tissue paper .

Flakes from the elephant ’s bones have revealed that this is the earliest evidence of animal butchery in India .
“ We interpret this specimen as an impact flake resulting from repeated hammering of an elephant ivory with a Harlan Stone implement , ” write the generator in their newspaper .
“ Initially , the osseous tissue was struck several times in an attempt to initiate the fracture . However , these initial attempts failed , requiring a subsequent , more emphatic blow , possibly with a heavier hammerstone , to full fracture the bone . The overall morphology of this bit closely resembles an impact flake produced in [ old ] marrow processing experiments . ”
The discovery is even more unusual because there is very minuscule evidence of hominins from the Amerindic subcontinent and only one fogy hominin has ever been determine there . The finding of 87 stone tools alongside the off-white helps the research worker patch together how these former human antecedent might have been live .
" So , the doubt is , who are these hominins ? What are they doing on the landscape and are they going after big biz or not ? " study writer and conservator of vertebrate paleontology at the Florida Museum of Natural History Advait Jukar say in astatement . " Now we screw for sure , at least in the Kashmir Valley , these hominins are eating elephants . "
The mystery deepens because the Harlan Stone tools likely used to extract the marrow from the elephant bones were made of a material called basalt . This case of rock candy is not found in the same field , therefore the team consider that the basalt was brought in from elsewhere before being made into tools by the former hominins . free-base on this , the team think the tools and the site are around 300,000 to 400,000 years older .
“ It might just be that people have n’t look nearly enough or are try out in the incorrect place , ” Jukar said . “ But up until now , there has n’t been any unmediated grounds of humansfeedingon large animals in India . ”
While the bone suggest the former human beings may have been rust the marrow , there is no grounds on the bones ofhunting , such as spear tips . The hominins could have stamp out the elephant , or could have expose it after it pop off .
The team even reckon there could be more evidence of slaughter out there waiting to be expose .
“ The thing I ’ve come to realize after many geezerhood is that you just need a lot more effort to go and find the land site , and you need to basically appraise and collect everything , ” Jukar said . “ Back in the Clarence Day when the great unwashed pile up dodo , they only collect the honorable skulls or limb bones . They did n’t collect all the shatter bone , which might be more indicative of flakes or breakage made by people . ”
The bone themselves are also sinful . They belonged to a genus of huge ancient elephants that are known asPalaeoloxodon . This genus is long nonextant but when they roamed the Earth it would have been more thantwice the weightof today ’s hold up African elephants .
The particular somebody the bones go to is thought to have been one orotund male person maturePalaeoloxodonbut two others are also represented in the dodo include at least one juvenile .
The research also unwrap that there is a minute of abnormal bone maturation within the skull of thePalaeoloxodon , which could have been have by a continuing sinus contagion . This bone ontogeny triggered by transmission is called periostitis and is well documented in human skeleton persist . The team have also identified the species asPalaeoloxodonturkmenicus , of which only one other less complete fogy exists .
ThePalaeoloxodongenus is interesting because the elephants have tremendous forehead with a peak . early species from Africa do not have the bulge , whileP. turkmenicusis in the middle with a big frontal bone but a greatly reduced tip .
“ It shows this kind of intermediate stage inPalaeoloxodonevolution , ” Jukar articulate . “ The specimen could assist paleontologist fill up in the story of how the genus migrate and evolved . ”
The research is issue as a couple of papers inQuaternary Science Reviewsand theJournal of Vertebrate Paleontology .
