NEFU scientists to study cave bear found on the Lyakhovsky Islands
Separately at least one preserved carcass of a cave bear cub found on the mainland of Yakutia, with scientists hopeful of obtaining its DNA.
More details of the finds are to be announced soon.
Until now only the bones of cave bears have been discovered.
The new finds are of ‘world importance’, according to one of Russia’s leading experts on extinct Ice Age species.
Scientist Lena Grigorieva said of the island discovery of the adult beast: 'Today this is the first and only find of its kind - a whole bear carcass with soft tissues. 'It is completely preserved, with all internal organs in place including even its nose. «Previously, only skulls and bones were found. This find is of great importance for the whole world».
The remains were found by reindeer herders on the island and the remains will be analysed by scientists at the North-Eastern Federal University (NEFU) in Yakutsk, which is at the forefront of research into extinct woolly mammoths and rhinos.
Russian and foreign colleagues will be invited to join the study.
The cave bear (Ursus spelaeus) is a prehistoric species or subspecies that lived in Eurasia in the Middle and Late Pleistocene period and became extinct about 15,000 years ago.
Preliminary analysis suggests the bear to be between 22,000 and 39,500 years old.
«It is necessary to carry out radiocarbon analysis to determine the precise age of the bear,» said senior researcher Maxim Cheprasov from the Mammoth Museum laboratory in Yakutsk. The finder transferred the right to research to the scientists of NEFU, he said.
Unique discovery of perfectly preserved extinct cave bear showing its teeth after up to 39,000 years.
Bolshoy Lyakhovsky Island, or Great Lyakhovsky, is the largest of the Lyakhovsky Islands belonging to the New Siberian Islands archipelago between the Laptev Sea and the East Siberian Sea in northern Russia.
A scientific programme for its comprehensive study will be prepared. We will have to study the carcass of a bear using all modern scientific research methods - molecular genetic, cellular, microbiological and others.
«The research is planned on as large a scale as in the study of the famous Malolyakhovsky mammoth,» said Dr Grigorieva, leading researcher of the International Centre for Collective Use of Molecular Paleontology at the NEFU’s Institute of Applied Ecology of the North.
Recent years have seen major discoveries of mammoths, woolly rhinos, Ice Age foal, several puppies and Cave Lion cubs as the permafrost melts in Siberia.
The International Center for Collective Use "Molecular Paleontology" was opened in March 2015 on the basis of the laboratory "Mammoth Museum named after P.A. Lazarev" RIAEN as a separate structural unit of the institute. The opening of the ICCU became possible due to the agreement on scientific cooperation on the project "Revival of the mammoth and other fossil animals", concluded between NEFU and the South Korean Sooam Biotechnological Institute on September 23, 2012. One of the priority areas of cooperation is joint research in the field of studying the genome of ancient animals.
