Gastropods from the Campanian–Maastrichtian Aruma Formation, Central Saudi Arabia
چکیده انگلیسی


• Aruma Formation in central Saudi Arabia comprises fifteen gastropod species belonging to fifteen genera.
• Gastropods have a close affinity to the Tethyan fauna known from other parts in Asia, Africa and Europe.
• Herbivoroes and predators are the dominant trophic groups of the identified taxa.
• The identified gastropods indicated shallow marine lagoonal and relatively open marine environment.

The gastropod fauna of the Upper Cretaceous Aruma Formation in central Saudi Arabia comprises fifteen species belonging to fifteen genera, fourteen families, and five clades. The species are not abundant at any individual stratigraphic level but are equally and irregularly scattered in the formation. The studied species come mainly from the Hajajah Member of Upper Cretaceous Aruma Formation in central Saudi Arabia. Calliomphalus orientalis (Douvillé, 1916); Coelobolma corbarica Cossmann, 1918; Turritella (Torquesia) figarii Quaas, 1902; Neoptyxis olisiponensis (Sharpe, 1850) and Otostoma (Otostoma) divaricatum (d’Orbigny, 1847) are recorded from the Upper Cretaceous of central Arabia for the first time. The identified species have a close affinity to the Tethyan fauna known from other parts in Asia, Africa and Europe. Herbivores and predators are the dominant trophic groups which may indicate shallow marine lagoonal and relatively open marine environment.
