Where did the 'Siberian unicorn' disappear?

The skull is well preserved: there are some cracks but no trace of pelletization, gnawing, and exfoliation. The fossils of the "unicorn" were examined by radiocarbon AMS-method analysis in the laboratory 14CHRONO Centre for Climate, the Environment, and Chronology (School of Geography, Archaeology and Palaeoecology; Queen's University Belfast; Belfast, UK). It turned out that the skull belonged to the animals that died 29,000 years ago.
"Most likely, it was a very large male of very large individual age (teeth not preserved). The dimensions of this rhino today are the biggest of those described in the literature, and the proportion are typical," said the University's scientist.
Elasmotherium sibiricum supposed to be extinct about 350,000 years ago. Its habitat was the vast territory from the Don River to the east of modern Kazakhstan. Overview Elasmotherium residue findings in the Pavlodar Irtysh showed quite a long existence of these rhinos in the southeast of the West Siberian Plain.
An extinction period of the "unicorn" can now be compared with the boundary between Kargin thermochron and Sartan cryochron of late pleistocene (boundary of MIS 3 and 2) in Western Siberia. These data are pushing us for mass radiocarbon studies of mammalian remains that were previously known as ancient and extinct more than 50-100,000 years ago.
"Our research makes adjustments in the understanding of the environmental conditions in the geologic time in general. Understanding of the past allows us to make more accurate predictions about natural processes in the near future: it also concerns climate change," summed up Shpanski.
