The Mysterious Mass Extinction Hidden in LA

Описание: Beneath the streets of Los Angeles lies one of the most prolific fossil sites in the world. At the La Brea Tar Pits, millions of fossils including giant sloths, dire wolves, saber-toothed cats, and mammoths have surfaced from ancient asphalt, offering a rare glimpse into a vanished world.

In this episode of Human Footprint, Shane Campbell-Staton joins paleontologist Emily Lindsey to investigate the sudden disappearance of North America’s megafauna around 13,000 years ago. Together, they follow the trail of ancient life through radiocarbon dating, fossil excavations, and lake-bottom sediment cores.

For decades, scientists debated whether climate change or human hunters were to blame. But new evidence points to a more complex and unsettling cause: a dangerous combination of warming temperatures, ecological disruption, and the spread of fires… ignited by us.

This isn’t just a story about extinction. It’s a glimpse of how past crises mirror the present, and a warning about where we could be headed next.
