Paleontologist Emily Lindsey uncovers the past beneath the streets of Los Angeles at the La Brea Tar Pits — home to the richest Ice Age fossil deposit in the world. Once mined for oil, this sticky site has revealed giant ground sloths, saber-toothed cats, and over five million fossils. It's a fossil jackpot that tells a 40,000-year-old story of life, extinction, and climate change.
