    A recent field survey of the Middle*-upper Triassic (upper Anisian to lowermost camian) paralic marine deposits of the Jilh Formation in central Saudi Arabia has yielded large quantities of vertebrate fossils. These finds prompt a revision of the existing faural list and include at least-one novel stratigraphical occurrence for the Arabian peninsula. The remains comprise sauropterygian marine reptiles (Psephosaurisans sp Nothosauras cf, tchernovi, Nothosauras cf giganteus, Simosaurus sp), a.lungfish.Ceratodus sp ), hybodontiform sharks (Hybodus sp) and saurichthy form actinopterygians Saurichthys sp). Palaeobiogeographical assessment reinforces Tethyan affinities for the assemblage and reflects the close proximity of the Arabian region to the .Sepbardic Realm , a compositionally distinct circum-Mediterranean faunal province characterized by hypersaline Muschelkalk facies
