Sanpetru Formation
The Sânpetru Formation is an early Maastrichtian geologic formation. Dinosaur remains are among the fossils that have been recovered from the formation. It is located in Romania, near Sânpetru village, part of Sântămăria-Orlea commune. It forms a component of the Hațeg Island fauna.
Description
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.
