The skull of Hyperodapedon sanjuanensis from the Ischigualasto Formation of Argentina. These rhynchosaurs had particularly pronounced hooked, beak-like jaws.
For #FossilFriday, here's the skull of Hyperodapedon sanjuanensis, a #rhynchosaur from South America that lived ~232 million years ago in the #Triassic. I got to study this specimen back in 2019 when I visited the @amnh.org in New York 🇺🇸
