Kangaroos – and their wallaroo and wallaby cousins – are some of the most recognizable, charismatic, and impressively strange mammals on the planet. This episode, we explore the surprising diversity of this group, we discuss how they manage to be world’s pre-eminent hoppers, and we delve into some of their unexpected fossil relatives. In the news: warm tyrannosaurs, sea star ancestors, traveling dinosaurs, and new cats.
