Both of the below answers are wrong. yes, the super continent of Pangaea broke up in the early jurassic, but that has nothing to do with the ice age. Also, the earth did not warm up during the ice age; It cooled down. This happened because the earth moved away from the sun, but still orbiting in the goldilocks zone. Massive glaciers were formed, and in their peak, they covered much of modern europe. About ten thousand years ago, the earth moved closer to the sun and the ice melt. Mammoths, mastodons, saber tooth cats, and the giant deer Megaloceros died, along with the dire wolf and short faced bears became extinct due to climate change, and competition with modern homo sapiens.
