Episode 45: Post K-Pg radiations

The Cretaceous-Paleogene (K-Pg) mass extinction was the latest of the 'big five' events. Approximately 75% of species went extinct, with the most notable victims being non-avian dinosaurs. But what happened afterwards? By which methods were some of the survivors able to spread to fill vacant niches?

The University of Bath's Dr Nick Longrich joins us to hypothesise about the dispersal mechanism of a very unusual group of ground-dwelling predatory reptiles called amphisbaenians (worm lizards).
