In a study published on Thursday, scientists shared their findings on a frozen, mummified sabre-toothed cub discovered in one of the coldest places on the planet.
A member of the species Homotherium latidens, the cub was discovered in 2020 in the Republic of Sakha in eastern Russia. This region can see temperatures as low as minus 90 degrees, according to NASA.
These extremely cold temperatures help create permafrost, or permanently frozen ground, which preserved the mummy of the sabre-toothed cub for at least 35,000 years.

The mummy, which included the cub’s head down to its chest and its front arms and paws, was encased in a piece of ice. Scientists added that incomplete pelvic bones with the femur and shin bones were also encased.
The cub was so well-preserved in the cold elements that scientists said they were able to conduct a historic first – to study the appearance of an extinct mammal that has no analogs in the modern era.
For example, the fur on the cub was able to be analyzed. Researchers noted that the fur was short, thick, soft and dark brown, measuring about 2-3 centimeters long. The fur was longer on parts of the cub, such as on its back, neck and in the corners of its mouth.

In addition to the mummy giving scientists a chance to study the cub’s appearance, it also showed how the cub and members of its species were able to survive in a cold climate.
Scientists pointed out that the cub had a wide paw, subsquare-shaped paw pads and the lack of a carpal pad, which are adaptations to the animal traversing through snow and cold temperatures.
Homotherium latidens are the extinct Eurasian cousins of the North American sabre-toothed cats. Scientists say the cats could grow to about 3 feet tall and 6.5 feet long, and weigh nearly 450 pounds.
