Natural Trap Cave is a pit in northern Wyoming into which countless animals have fallen and met their untimely demise since the Pleistocene. Paleontologists today find the cave a treasure trove — a stunning record of the species that have long roamed the area. The mammalian fossils left behind shed light on the climate, food sources and migration patterns of these species from earlier eras.

Careful excavation work over the years that has involved sifting for bones, extracting ancient DNA, and looking for prehistoric pollen has revealed not just the plants and animals that once populated this part of the world, but also the ecosystems and climates that governed it. It also has required some rather advanced rappelling skills.

In this episode, host Ari Daniel speaks with vertebrate paleontologist Julie Meachen and Smithsonian contributing writer Michael Ray Taylor about what rappelling into Natural Trap Cave reveals about its contents and what it can tell us about Earth’s past.
