A new episode of Palaeocast is out. This one is about Terror birds. These are large flightless birds that evolved after the K-Pg extinction event. They originated in South America and migrated up to North America when the Isthmus of Panana formed almost 3 million years ago. Personally, I've always found these animals fascinating!
Terror birds, or phorusrhacids as they are known scientifically, are a group of large, flightless birds that lived during the Cenozoic, and truly lived up to their name. Known for their large, powerful skulls, and enormous beaks, these birds are unlike the flightless birds we have alive today. Despite their strange appearance and unique morphology, terror birds aren’t well known in popular culture. What were they doing? How big did they get? What did they eat?
In this episode, we talk to a leading terror bird expert, Dr Federico “Dino” Degrange from the Centro de Investigaciones en Ciencias de la Tierra (CICTERRA) in Córdoba, Argentina to get answers to these questions. We discuss some of his recent research, and what we know (and don’t know) about phorusrhacids today.
