Abstract |
: |
1202 specimens of gastropod shells were collected from different locations near Jeddah city. 507 specimens were collected from a site located directly north of the village of Durrat Al Arus, north of Jeddah where the section consists of calcareous claystone attaining a thickness of 4.5 meters with assemblage of corals. 695 specimens were collected from Ash Shaibah area, south of Jeddah where the section consists of carbonates and a thin layer of calcareous sandstone at the top. The thin layer has higher diversity and abundance of gastropods than the other layers which may be related to the last interglacial marine isotope stage 5e (MIS 5e) at Late Pleistocene. In this study, 94 gastropod species are identified. They belong to 4 subclasses, 9 orders, 22 superfamilies, 38 families, and 74 genera. Seven species were recorded for the first time in the Late Pleistocene deposits of the Saudi Arabia. These species are Rhinoclavis vertagus, Monetaria moneta, Purpurcapsula exigua, Ranularia sarcostoma, Sabia conica, Nassarius albescens, and Coralliophila erosa. Seven species and one subspecies were record for the first time in the Red Sea. These species are Cerithium salebrosum, Euplica turturina, Conus auricomus, Nebularia pellisserpentis, Mitra turgida, Strigatella vexillum, Melampus fasciatus, and Pustularia bistrinotata jandeprezi. Three species may be new, they belong to the genera Trivia, Conomurex, and Raphitoma. The genus Raphitoma is first record in the Red Sea. |
