Episode 32 - Naracoorte Caves, Australia

Over the past several hundred thousand years, Australia has witnesed numerous ice age cycles, ecosystems dominated by giant marsupials, the arrival of humans, the extinction of those giant animals, and more. And there may be no better window into this dynamic time period than the world-famous Naracoorte Caves of South Australia.

In the news: an infected dinosaur, humans' earliest steps in Canada, horny dinosaurs, and a four-eyed ancient lizard.
