This week, we’re joined by Blake de Pastino from the YouTube channel PBS Eons to talk about how plants, animals, and geologic events used to be so… huge. There are still blue whales and massive natural disasters, but the days of the Megalodon have passed. So were those big tunnels in South America really dug out by giant ground sloths? Where is the largest impact crater in the Solar System? And did humans really huddle under the skeletal remains of the giant armadillo-like Glyptodon?
