43,000-Year-Old Frozen Lion Cubs Found in Russia

Scientists in Russia have found what is believed to be the best preserved specimen of a 43,000-year-old cave lion cub. They call this cub Boris, and estimate he was about 1 month old. If he had lived to be full-grown, Boris would have been larger than a modern-day lion. Russia’s frozen terrain has kept much of this primordial animal life intact, but climate change and warming temperatures are exposing more of the past.
