Episode 99: Megalodon and Marine Megafauna

Undoubtedly, Megalodon is the world’s most famous extinct shark is and in this episode, we hear everything we know about this taxon, its ecology and how it got to be so big. Its ultimate extinction is also considered, not in isolation, but placed in the wider context of the entire marine ecosystem.

Joining us is Dr Catalina Pimiento of  Swansea University.
