Summary

Hadrosaurs (the so-called “duckbill” dinosaurs) and their fellow ornithopods were among the most abundant and successful dinosaur groups of all time. This episode, we discuss their evolution and diversity, and we explore some of the most outstanding and unique features of the group, including their incredible fossil record, complex social behaviors, wacky head ornaments, and their truly incredible mouths. In the news: fluorescent mammals, snake tracks, leaf mining, and terror bird footprints.
