  Quseir Formation (Egypt) | |
The Quseir Formation is a geological formation in the vicinity of the Kharga Oasis in Egypt. It is Campanian in age. The lithology largely consists of soft shale with hard bands of sandstone, siltstone and phosphorite. The environment of deposition was nearshore to freshwater fluvio-lacustrine characterized by moist and aquatic habitats with a tropical warm-humid climate. It is conformably overlain by the marine late Campanian-Maastrichtian Duwi Formation, and unconformably overlies the Turonian Taref Formation. The sauropod dinosaurs Mansourasaurus and Igai are known from the formation, as well as the proximal fibula of an indeterminate theropod and possible remains tentively assigned to Spinosaurus. Additionally the lungfish genera Lavocatodus and Protopterus, the crocodyliform Wahasuchus and the bothremydid turtle Khargachelys are also known.
