The woolly mammoths survived centuries longer than their counterparts and lived on Wrangel Island in the Arctic Ocean, a more recent study found. The mammals had been divided from other mammoths surviving across the Northern Hemisphere by rising sea levels resulting from global warming start 15,000 years before, as reported by a group of researchers in Germany, Finland and Russia.

Scientists have been fascinated by the woolly mammoth and many think we might be able to attract the species back from the deceased. But there’s still a great deal we don’t know about the beastly pachyderms.

In the new researchstudy published in the journal Quaternary Science Reviews, researchers studied the isotope compositions of carbon, nitrogen, sulfur and strontium in a set of mammoth bones and bones ranging from 40,000 to 4,000 years old from Northern Siberia, Alaska, the Yukon and Wrangel Island. Their aim was to test any potential shifts in the mammoths’ habitat and diets and also to look for signs of a disturbance within their own environment. The scientists discovered that nitrogen isotope compositions of mammoths on Wrangel Island and the collagen carbon failed to shift when the climate heated up around 10,000 years before, during what has been stable living conditions, before mammoths died off, and they remained unchanged.

Woolly mammoths at the Ukrainian-Russian plains expired around 15,000 years before, and the ones in St. Paul Island in Alaska expired around 6,000 years ago. The final of those mammoths had significant changes within their isotopic composition, which suggests changes in their environment so on before they went out there. Wrangel Island mammoths met there demise some 4,000 year ago.

The researchers also discovered that the carbonate carbon isotope values revealed a gap in the fats and carbohydrates in the diets of the Wrangel Island mammoths and their counterparts.

“We presume this reflects the tendency of Siberian mammoths to rely on their own reserves of fat to live through the exceptionally harsh ice era winters, whereas Wrangel mammoths, surviving in milder conditions, only did not need to,” said Laura Arppe from the Finnish Museum of Natural History Luomus, University of Helsinki, in a press release. Arppe directed the group of research workers.

Wrangle Island bones had degrees of strontium and sulfur that indicate a more powerful flow of bedrock near the end of the population’s existence, which may possibly have affected the standard of the mammoths’ drinking water, the study included.

The researchers think what may have led to this Wrangel Island mammoths’ demise some are shortterm events including extreme weather like rain on snow that would have made conditions too icy for mammoths to find food that is . That extinction may have led to a drop in population and, ultimately.

The spread of humans is just another element. The earliest evidence of humans in the island dates back again to some 100 years after the most recent bone. It’s improbable that we’ll find evidence that humans hunted mammoths on Wrangel Island, the researchers say, however, we can’t rule out the risk they may have played part in their own extinction.
