research worker have pulled the mummy of a new-sprung saber - toothed qat that pass away at least 35,000 old age ago from Siberia ’s permafrost — and the kitty still has its whiskers and claws attached .
A new analysis of the kitty ’s spectacularly - preserved brain and upper organic structure shows it was just 3 week old when it died in what is now Russia ’s northeastern Sakha Republic , also known as Yakutia . Scientists found pelvic os , a femur and shin bone encased in a block of ice together with the mummy . The circumstance of the animal ’s death are unsung .
The mummified head of a young saber-toothed cat unearthed from Siberia’s permafrost.
It is extremely rare to discover well - save remains of saber - toothed cats , and this one belongs to the speciesHomotherium latidens , according to a study published Thursday ( Nov. 14 ) in the journalScientific Reports . Saber - toothed cats of the extinct genusHomotheriumlived across the ball during the Pliocene ( 5.3 million to 2.6 million year ago ) and earlyPleistocene(2.6 million to 11,700 year ago ) epochs , but evidence suggest this group became less far-flung toward the end of the Pleistocene ( also known as the last chicken feed eld ) .
" For a farsighted time , the latest presence ofHomotheriumin Eurasia was recorded in the Middle Pleistocene [ 770,000 to 126,000 years ago ] , " researchers indite in the work . " The discovery ofH. latidensmummy in Yakutia radically expands the understanding of distribution of the genus and confirms its presence in the Late Pleistocene [ 126,000 to 11,700 years ago ] of Asia .

Researchers reconstructed the kitten’s skeleton using a 3D computer model.
The small , inscrutable - rooted mummy showsH. latidenswas well - adapted to ice age condition , according to the written report . The researchers compared the carcass to that of a innovative 3 - week - oldlion(Panthera leo ) lad and found the saber - toothed kitty had wider mitt and no carpal pads — pads on the articulatio radiocarpea joint that act as shock absorber in today ’s felid . These adaptation enable sabre - toothed cats to walk with simpleness in snow , while thick , subdued fur observe on the mummy shield the predators against polar temperature .
The comparability with the Leo revealed that saber - toothed cats had a large mouth , smaller ears , longer forelimbs , darker hair and a much thicker neck . Researchers already bang from canvas the skeletal frame of adultHolotheriumthat these saber - toothed Caterpillar hadshort bodiesand elongated limb , but the new research shows these feature were already present at the eld of 3 weeks .

Radiocarbon datingof the mummy ’s pelt suggested the kitten has been lay to rest in permafrost for at least 35,000 twelvemonth , and maybe 37,000 old age . The carcass was pulled from the banks of Yakutia ’s Badyarikha River in 2020 , and its discovery has enabled researcher to describe , for the first time , physical characteristics ofH. latidens , include the grain of these cats ' fur , the shape of their gag and the distribution of their muscularity pot .
Remarkably , the mummy still had incisive claws and whiskers ( or vibrissae ) attached to it . However , " the mummy cilium were not preserve , " the researchers note in the cogitation .
The newfangled psychoanalysis name the species the mummy belong to and its most salient features , but its authors are already working on a new paper . " The anatomical features of the discovery will be discuss in more detail in a subsequent paper , " they wrote .
