The Quseir Formation is a Geological Formation in the vicinity of the Kharga Oasis in Egypt. It is Campanian In age. [1] The lithology largely consists of soft shale with hard bands of sandstone, siltstone and phosphorite.[2]The environment of deposition was nearshore to freshwater fluvio-lacustrine characterized by moist and aquatic habitats with a tropical warm-humid climate. It is comformably overlain by the marine late Campanian-Maastrichtian Duwi Formation, and unconformably overlies the Turonian Taref Formation. The dinosaur Mansourasaurus was discovered in the formation.[3], Additionally the lungfish genera Lavocatodus and Protopterus [4] and the Crocodyliform Wahasuchus[5] are also known.
