Hasandong Formation
The Hasandong Formation is an Early Cretaceous (Aptian to Albian) geologic formation in South Korea. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.[1] Tracks of the pterosaur ichnogenus Pteraichnus have also been recovered from the unit.[2]
