Great rhinoin survived that could have been the origin of the unicorn legend until at least 39,000 years ago – much longer than what he thought of before.
She is called a Siberia unicorn, the animal had a long horn on its nose, and reached the Eurasia grass.
New evidence shows that the pet could eventually die because it eats such a food.
Scientists say that knowing more about the animal's eradication can help save the remaining rhinos on the planet.
Rhinos is particularly at risk of disappearing because they are very excited about their habitat, says Professor Adrian Lister of the Museum of Natural History, London, who led the study.
"Any change in their environment is a danger to them," he told BBC News. "And of course, what we have also learned from the fossil record is that once a species has gone, that's it, it's gone well."
Boosting in four strong tons, with an exceptional single horn on top of it, the "Siberian unicorn", divided the ground with early modern men up to at least 39,000 years ago.
What do we know about the ancient rhinoin?
The ridge, Elasmotherium sibericum, has disappeared between 200,000 and 100,000 years ago.
Through radiocarbons dating a total of 23 specimens, researchers found that the Ice Age fan really survived in Eastern Europe and Central Asia up to at least 39,000 years ago.
They also insulate the ancient Rhinoin DNA for the first time, showing it as part of the modern group of rhinos about 40 million years ago.
Siberian unicorn abolition marks the last point of a whole group of rhinos.
Why could it have disappeared?
The study also included examining the teeth of the animals, confirming that grazing on dry, dry grasses.
"He was actually walking like a prehistoric lawn maker … it's only grazing along the ground," said Professor Lister.
The specialized rino diet may have been falling. As the Earth warmed up and began to emerge from Ice Age around 40,000 years ago, shrub grassland began, with a similar pushing the animal to disappear.
Hundreds of species dropped large mammals after the last Ice Age, due to climate change, losing vegetation and human hunting.
What does he tell us about the fate of modern rhinos?
Today, only five species of rhine species are left. There are very few surviving outside national parks and reserves due to ongoing pain and loss of habitats for many decades.
By studying fossil rhinos, scientists can learn more about the fate of the prehistoric rhine species that once the planet had dropped and how they adapt to climate change and human pressures.
Where are unicorn myths coming?
Legends of the unicorn, or an animal with one corn, have been for miles.
Some have argued that the rhine horn could have been the basis of unicorn legends, although other animals – such as the bad store – are more likely to be competitive.
