The latest findings used radiocarbon days and genetic analysis in 23 rhinorrhea samples to reveal the life of the mysterious Elasmotherium sibiricum of 3.8 tonnes, which was believed to have died out about 200,000 years ago.

According to the results, The "Siberian unicorn" – which would have lived in modern Russia and its extent of movement – expanded to areas in Mongolia, northern China and Kazakhstann- is extinguished by changes in the environment that affected the type of grass and the plants they ate.

They also explained that people are not the cause of extinction of this species.

"In addition, the persistently limited geographical scope of Elasmotherium (possibly also linked to its specialized habitat), as well as a small amount of population and a slow reproduction rate that is associated with its large body size, would predispose it extinction in relation to environmental change", The authors added.

Scientists have suggested that the extinction of a Siberian unicorn provides a useful case study "The display of scarce resistance to rhinoceroses for changing the environment".
