The Undiscovered Cave

The Secret Lives of Parks

Oct 5 2021 • 21 mins

At Grand Canyon National Park, explorers discovered a trove of lifelike bat fossils that provide a genetic record spanning 30,000 years. Experts reflect on why these particular remains are so rare and special, and how the National Park Service has spent years documenting and learning from the ancient life that surrounds us in our parks. Host Jennifer Errick explores the issue with guests Shawn Thomas, volunteer caver and Subterranean Team Manager at Bat Conservation International; Vincent Santucci, Senior Paleontologist and Paleontology Program Coordinator for the National Park Service; and Dr. Carol Chambers, Professor of Wildlife Ecology at Northern Arizona University.
