Scientists have said that an astonishingly well-preserved cave lion cub found in Siberia's permafrost lived 28,000 years ago and may even still have traces of its mother's milk in it -- a female cub named Sparta, found in Russia's Yakutia region in 2018. This video features a second lion cub named Boris, that was found the year before and that lived around 43,448 years ago, according to a study published in the Quaternary journal. Valery Plotnikov, one of the study's authors, said Sparta was so well preserved that it still had its fur, internal organs and skeleton. The two cubs aged 1-2 months were found by mammoth tusk collectors. Two other lion cubs named Uyan and Dina have also been found in the region in recent years.
