CALGARY , Alberta — Half a million long time ago , the Arabian Peninsula was n’t a sandy desert but rather a lush , tight landscape . There , a mammoth elephant — 50 percent orotund than today ’s giving elephant — tromped around an ancient lake before pall , a new fossil skeleton reveals .
The titan , known asElephas recki , is an ancient elephant mintage that be from about 3.5 million old age ago to about 300,000 years ago and lived in parts of Africa and the Middle East , enjoin study lead investigator , Iyad Zalmout , a palaeontologist with the Saudi Geological Survey in Jeddah .
A tusk belonging to the 500,000-year-old elephant that researchers discovered in Saudi Arabia’s Nafud Desert.
Researchers first start uncovering the newfound animal ’s cadaver in northwestern Saudi Arabia ’s Nafud Desert in 2014 , but other part of the same individual were excavate as recently as this year , and archeological site work is on-going , said study co - researcher Dan Fisher , the film director of the Museum of Paleontology at the University of Michigan .

So far , research worker have discovered about 60 percent of the elephant ’s fossilized bone , gain it " one of the considerably - preserved object lesson of this species from this part of the world , " Fisher told Live Science . Scientists have found fossils of this ancient Asiatic elephant relative before , including a1.8 - million - class - old individualfrom the Turkana Lake Basin in northern Kenya .
Fisher added that althoughE.reckiwas 50 percent large than the largest modern elephants , it was vastly weighty , " at least twice the weight of today ’s elephant , if not more , " Fisher allege .
The ancient elephant’s scapular bone (shoulder blade) and humerus (upper arm).
The strapper ( a manlike elephant ) had touch adulthood before it died , an analytic thinking of its pearl revealed . After the animate being kicked the bucket , the ok sands of an ancient lake system maintain the creature ’s bones . Its fossils are so intact , researchers aremaking 3D modelsof some of them using a optical maser - scanning analog-to-digital converter so that they can be partake in nearly online with other researchers , Fisher tell .
" This work is provide a more detailed understanding of the pearl of this species of elephant , " Fisher tell . " This is important because it ply the foundation for more - thorough analyses of new site where we foresee more remains of this case of elephant will occur . "
Human contact?
There was no evidence that human ancestor lived at this site 500,000 years ago , when this picky elephant stomped around , but the researchers allege they hope to come up evidence that the two coexist atother fossil sites .
Elephants and other man took like route as they trekked out of Africa and spread into the Middle East and Eurasia , so it ’s potential they hybridize paths at some stage , Fisher said . ( Note that research worker are n’t lecture aboutHomo sapiens , which developed between 200,000 and 300,000 years ago , but rathertheir hominin predecessors . )
" We know that early man were coeval of these elephants in this part of the Arabian Peninsula , " Fisher said . " Although we have not yet found sites where these elephants are associated with grounds of human body process , we want to be ready to render any such discovery when and if they do arise . "
At the time this elephant conk , ancient elephant and other human being would have see a wet climate that irrigate a green landscape painting of the Arabian Peninsula , Zalmout said . During parts of thePleistocene(an epoch lasting from 2.6 million to 11,700 years ago ) , Saudi Arabia had a majuscule multifariousness of animals than it does today , including craniate such as camel , gazelles , antelope and carnivores , admit big cat and hyena antecedent .
" It was a vibrant place , " Zalmout told Live Science .
The research , which has yet to be published in a peer - refresh journal , was presented here on Aug. 23 at the 2017 Society of Vertebrate Paleontology group meeting .
