Jizera Formation (Czech Republic)

The Jizera Formation is a geologic unit of Late Cretaceous (Turonian) age, located in the Czech Republic. It is a unit of the Bohemian Cretaceous Basin. ^{[1] [2]} It consists of fluvial to shallow marine sediments ^[1] and pterosaur fossils are among the remains found in the Jizera Formation. The type locality of the Jizera Formation is a quarry in Zářecká Lhota. ^{[3] [4]}
