Angelina Sadovnikova, then 11, came across the mummified Pleistocene rodent in a cavity left by woolly mammoth tusk diggers.
The girl, now 14, was with her mother when she made the frozen find on the shore of Tirekhtyakh River close to the Arctic Circle in the Yakutia region of Siberia, say scientists.
She took the preserved lemming to local historian and archaeologist Prokopyi Nogovitsyn who in turn alerted biologist professors Nikita Solomonov and Vyacheslav Rozhnov.
Angelina is shown in the picture with the two academicians.
The Ice Age lemming discovery was immediately moved to Moscow for detailed study.
With an age of a little more than 41,000 years, it is the oldest lemming in the world, shows radiocarbon analysis
At a length of 166mm – and slightly larger than modern day Siberian brown lemmings – the ancient herbivore is remarkably well preserved.
Fur remains on the back, sides and abdomen, although not on the head.
On the dorsal side, the colour of the fur is dark grey, on the sides and the ventral side it is greyish-yellow, and light, brighter on the back of the body.
There is no longitudinal dark strip on the back.
X-rays showed that all the bones, including the skull, were well preserved although the internal organs did not survive.
The mummy’s thighs were found to be broken.
A new study reports: ‘The finding of the Tirekhtyakh lemming is of great importance for understanding the evolution of this most important group of mammals in the Arctic communities.’
It was reported in Proceedings of the Russian Academy of Sciences (Doklady Akademii Nauk), volume 489, issue 1. The research was reported by N+1 science news website.
The mummy is between 41,305 and 41,885 years old, say scientists.
Disclosure of the schoolgirl’s discovery of the oldest prehistoric lemming follow exciting scientists discoveries of mummified animals frozen in the permafrost as it gradually thaws due to climate change.
Permafrost-preserved remains of woolly mammoths and rhinos have been found along with cave lions, wolves and other creatures.
The scientific team that studied the mummified lemming were:
Academician, Professor Alexey Lopatin, head of the Paleontological Institute, Russian Academy of Sciences (Moscow), Dr Nikita Solomonov, Corresponding member to Russian Academy of Sciences (Yakutsk), Dr Natalya Serdyuk, Paleontological Institute, Russian Academy of Sciences (Moscow), Dr Evgeny Maschenko (Paleontological Institute, Russian Academy of Sciences (Moscow), Professor Dmitry Mukha (Vavilov Institute of General Genetics (Moscow), and Professor Alexander Agadjanyan, Paleontological Institute, Russian Academy of Sciences (Moscow)
