camel are the notice creature for the desert , but research worker now have evidence that these shaggy creature once hold out in the Canadian High Arctic .
The fossil remains of a 3.5 - million - class - old camel were found onEllesmere Islandin Canada ’s northernmost territorial dominion , Nunavut . The camel was about 30 percent bighearted thanmodern camelsand was identified using a proficiency called collagen fingerprinting . The finding , detailed today ( March 5 ) in the journal Nature Communications , propose that modern camel stemmed from elephantine relatives that know in a forested Arctic that was jolly warmer than today .
High Arctic camels, like those shown in this illustration, lived on Ellesmere Island during the Pliocene warm period about 3.5 million years ago.
" It ’s the first grounds that camels were ever there , " lead study generator and paleobiologist Natalia Rybczynski of the Canadian Museum of Nature in Ottawa assure LiveScience . “It is surprising because normally we associate camel with arid and semi - desiccated habitats . "

Camels , which belong to theCamelusgenus , originated in North America during the Eocene period about 45 million age ago , and by and by crossbreed to Eurasia over the Bering Isthmus , a landbridge between Alaska and Russia . Their close relative are llamas , alpacas , vicuna and guanacos .
The researcher found about 30 pieces of off-white that were part of a camel ’s tibia , or shin bone . The fossil ’s location displace the acknowledge range of North American camel northward by about 745 miles ( 1,200 kilometers ) .
The camel ’s identicalness and age were determined via collagen fingerprinting , a technique that value the amount of a osseous tissue protein called Type I collagen . dissimilar mammals have characteristic amounts of this protein , which outlive longer than many other biological atom in the torso .
The team date the fossil to close to 3.5 million years ago , a period fuck as the mid - Pliocene warm time period . The global temperature was about 3.5 to 6 degrees Fahrenheit ( 2 to 3 degrees Celsius ) warm than today , Rybczynski said , and about 33 degrees F ( 18 degrees C ) heater where the camel was retrieve , with temperature averaging around 30 level F ( minus 1.4 degree C ) . TheCanadian High Arctic was forestedthen .

The fossil specimen close resemble modern dromedary camels , based on the fingerprinting , but was about a third larger in size . It also bears similarity to the giant Yukon camel that lived about 1,240 international nautical mile ( 2,000 kilometer ) away from the site where the ancient camel bones were discovered .
The research worker design to continue searching for camel stay on in the High Arctic . " We hope to find more , " Rybczynski tell .
