Densuș-Ciula Formation
The Densuș-Ciula Formation is a geological formation in Romania whose strata date back to the Late Cretaceous. It forms part of the Hațeg Island assemblage. Dinosaur remains are among the fossils that have been recovered from the formation. It is divided up into three members, the lower member is noted for high content of Volcanogenic [massive sulfide ore deposit|volcanogenic] material and is poorly fossiliferous. The Middle member consists of silty mudstones, sandstones and conglomerates containing volcanogenic clasts and is richly fossiliferous, while the upper member consists of matrix supported red conglomerates and is poorly fossiliferous.
