The World Famous La Brea Tar Pits

The Rancho La Brea Tar Pits is one of the world's most famous fossil localities, located 5 miles west of downtown Los Angeles. Near the end of the Ice Age, about 40,000 to 10,000 years ago, sabertoothed tigers and woolly mammoths roamed the Los Angeles Basin. Some of these animals, along with countless other animals and plants, became mired in pools of natural tar - a tragic ending for many prehistoric creatures, but a boon for today's paleontologists studying the Ice Age.
