With their giant axe-like beaks and powerful clawed legs, these giants have gained the nickname “terror birds.” This episode, we explore what makes these birds unique, how they varied across their diversity, and what exactly they were doing with all those terrifying tools. In the news: a bitten plesiosaur, wildflower adaptation, a new croc, and dinosaur parents.
