Happy Croc Month! Alligators and caimans are the living members of the family Alligatoridae. In this episode, we explore how the gator lineage differs from other crocs, and we’ll dive into the fossil record of the extended gator family tree, a history that includes a diversity of species and some of the largest crocodilians to ever live. In the news: Australian pterosaurs, mega-geese, Neanderthal art, and social ants.
