Palaeocast has a new episode up.  It’s called Pterosaurs.  There is quite a bit of information on their evolution, anatomy, and even behaviour.  A previous episode covered the aerodynamics of their flight.  Enjoy!

Pterosaurs were the first vertebrates to achieve powered flight, and lived in the skies above the dinosaurs during the Mesozoic. They’re often mistakenly identified as dinosaurs, but are in fact a separate, closely related group. This group has recently undergone a revival, with more research on pterosaurs happening now than ever before. Where are they found? How diverse was this group? How did they evolve?
