The Densuș-Ciula Formation is a geological formation in Romania, with strata dating to the Late Cretaceous. It forms part of the Hațeg Island assemblage, with dinosaur remains among the fossils recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, Europe)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 588-593. .
The formation is divided into three members. The lower member contains a high proportion of volcanogenic material and is poorly fossiliferous. The middle member consists of silty mudstones, sandstones, and conglomerates containing volcanogenic clasts, and is richly fossiliferous. The upper member is composed of matrix-supported red conglomerates and contains few fossils.
Fossil content Indeterminate dromaeosaurid and possible indeterminate troodontid remains present in Județul Hunedoara, Romania. An unnamed theropod is also present.
