Quseir Formation (Egypt) |
The Quseir Formation is a geological formation in the vicinity of the Kharga Oasis in Egypt.[1] It is Campanian In age.[2] The lithology largely consists of soft shale with hard bands of sandstone, siltstone and phosphorite.[3] 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 dinosaur Mansourasaurus is known from the formation,[4] as well as the proximal fibula of an indeterminate theropod.[5] Additionally the lungfish genera and Protopterus[6] and the Crocodyliform Wahasuchus[7] are also known.
