July 26, 2006 (available for download July 27, 2006) Dinos and Carnivorous Kangaroos
Dinos are still big, even though they vanished from the landscape 65 million years ago: it seems we just can't get enough of these economy-sized lizards.
Meet the only ichnologist* in Canada, and discover what hes learned about dinosaur behavior from the footprints they leave behind.
Also, a new theory about what really obliterated these scaly hulks (are rocks from space out, and magma from Earth in?)
Plus, why T-Rex never needed corrective lenses and the discovery in Australia of ancient, flesh-eating kangaroos.
