The frozen stays of a sabre-toothed cat regarded as about 31,800 years outdated have been studied for the primary time in historical past, in accordance with a research.
The cub’s mummified stays, together with its head, entrance arms and paws, and a part of its chest, had been discovered well-preserved in Arctic permafrost on the banks of the Badyarikha River in Yakutia, in Russia’s Siberia area, in 2020.
“Findings of frozen mummified remains of the Late Pleistocene mammals are very rare,” the researchers defined, referring to the interval by which it lived.
They added: “For the first time in the history of palaeontology, the appearance of an extinct mammal that has no analogues in the modern fauna has been studied.”

When in comparison with the stays of a contemporary lion cub of an identical age, there have been “significant differences”, mentioned the consultants.
The kitten, which was about three weeks outdated, has wider paws with their width virtually the identical as their size.
It additionally doesn’t have carpal pads (shock absorbers) which is regarded as an adaptation to low temperatures and strolling in snow.
‘Giant mouth, small ears and large neck’
The prehistoric animal additionally has a “large mouth opening”, small ears and a “very massive neck region” together with elongated forelimbs.

Its neck is “longer and more than twice as thick” as the fashionable cub’s, and the mouth opening is about 11% to 19% larger.
“The difference in (neck) thickness is explained by the large volume of muscles, which is visually observed at the site of separation of the skin from the mummified flesh,” mentioned the research, which was carried out by A V Lopatin of the Russian Academy of Sciences in Moscow and colleagues.

The ears are additionally larger up on the cranium of the cub.
When full, the entire animal would have been about 35cm lengthy.
It was decided that it shared traits with the subfamily Machairodontinae, particularly the Homotherium genus – cats with sharp, curved sabre tooth that existed round 12 million to 10,000 years in the past in North America and Europe.
The mummified physique is roofed with brief, thick, comfortable, darkish brown fur with hair about 20-30mm lengthy.
And the fur on its again and neck is longer than on the legs.
The authors additionally wrote that “one of the striking features of the morphology of Homotherium, both in adults and in the studied cub, is the presence of an enlarged premaxillary bone”.
This jaw form comprises an “expanded row of large cone-shaped incisors”.
The research was printed within the journal Scientific Stories.
