The Sânpetru Formation crops out in the central to southern Hațeg Basin along the Bărbat River and comprises sandstones and mudstones deposited in a wet floodplain environment characterized by braided fluvial channels. The formation is correlated with the Densuș-Ciula Formation of the northern section of the same basin, both dating to the Maastrichtian of the Late Cretaceous.[2]
