Facts. Cave Lions lived from around 950,000 Years Ago - 9,000 Years Ago. Along with almost all major 'Ice Age Giants', they became extinct at the end of the Last Ice Age Glacial period, as the Ice Caps retreated and the climate warmed up.

Standing 5 feet tall, measuring 11.5 feet (3.5 m) in length, and weighing more than 318 to 363 kg (700 to 800 lbs.), the Cave Lion was the largest cat that has ever existed, larger than modern lions of today and slightly bigger than tigers.
