The video shows scientists examining a dead lion cub. They take hair samples from the tiny corpse, which looks like it might have died only a few days ago. In fact, it has been deceased for nearly 30 millennia—covered in permafrost in Siberia until recently.
Sparta, as this female cave lion is called, is estimated to be 27,962 years old, according to a study published this month in the journal Quarternary. It may be the most well-preserved specimen ever found—so intact that she still has whiskers, reports Carly Cassella of ScienceAlert. Sparta was likely one or two months old at the time of death.
Scientists found this Ice Age cave lion (panthera spelaea) and another less-intact cub named Boris, estimated to be 43,448 years old, at a dig site near the Senyalyakh River in eastern Siberia above the Arctic Circle. Larger than African lions, the species lived in colder climates across Eurasia until going extinct about 10,000 years ago, reports Tim Fitzsimmons of NBC News.
“To my knowledge, this is the best-preserved frozen specimen from the last Ice Age ever found,” study author Love Dalén, an evolutionary geneticist Stockholm University’s Centre for Palaeogenetics, tells NBC News. “Sparta is in near-perfect condition.”
Cave lions coexisted with early humans for thousands of years, according to the study. For example, the Chauvet Cave in France depicts cave lions drawn on walls. The early cave paintings are estimated to be more than 30,000 years old.
The coloration of cub fur appears different than that of mature cave lions, requiring further study to determine if aging causes changes. Researchers also noted similarities in the fur between the Ice Age big cats and lions that still roam the savannas of Africa. The species is thought to have smaller manes than African lions while adapting to exist in colder climates.
“Cave lion fur also has a long thick fur undercoat consisting of strombuliform aeriferous fur hair,” the report states. “It covers the body of a cave lion cub evenly and most likely helped cave lion cubs adapt to the cold climate.”
While generally intact, scans of the cub corpses showed they had suffered skull damage, dislocated ribs and other injuries at the time of death. No signs of predation were found, leading researchers to speculate the cub had died accidentally.
“Given their preservation they must have been buried very quickly,” Dalén tells Katie Hunt of CNN. “So maybe they died in a mudslide, or fell into a crack in the permafrost. Permafrost forms large cracks due to seasonal thawing and freezing.”
Scientists are hoping to sequence the genome of both cubs to gain a better understanding of the extinct species.

12,000 Year Old Massive Underground Tunnels Are Real And Stretch From Scotland To Turkey
Mysterious tunnels have been discovered in Scotland that stretch all the way to Turkey, however, researchers are still unsure of why or how they were created.
What makes them all the more mysterious, is how absolutely amazing they are, and how meticulously they were created.
The Secrets
These thousands of Stone Aged underground tunnels have left scientists completely perplexed. Dr. Henrich Kusch explained in his book entitled ‘Secrets of the Underground Door to an Ancient World’ that the tunnels had been dug under literally hundreds of Neolithic settlements throughout Europe.
