Decapods are a group of crustaceans that include such well-known families as crabs, lobsters and shrimp. Whilst crustaceans are known from as early as the Cambrian, we don't see the first decapods until Devonian. Over the course of their evolutionary history, decapods have remained relatively conservative in their morphology with the exception of some interesting forms in the Mesozoic. In this episode, Dr Carrie Schweitzer, Kent State University, gives us a run-down of the taxonomy and evolutionary history of the decapods and we explore the Middle Triassic Luoping Biota.
