Cave lion cub found in Siberian permafrost

In news

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.

Details
  • The female cub, named Sparta, was found at the Semyuelyakh River in Russia's Yakutia region in 2018 and a second lion cub called Boris was found the year before, according to a study published in Quaternary.
  • The cubs were found 15 metres apart but are not only from different litters but were also born thousands of years apart.
  • Boris, a male cub, lived around 43,448 years ago.
  • 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.
Permafrost
  • It is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight.
  • These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.
  • Permafrost covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath.
  • Although the ground is frozen, permafrost regions are not always covered in snow.
