   Episode 240 - Terror Birds

   For most of the Cenozoic Era, South America was home to an incredible group of predatory birds called phorusrhacids, which included some of the largest carnivorous birds of all time. 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. Time markers:Intro & Announcements: 00:00:00News:…
