This study describes the chiton fauna (Mollusca, Polyplacophora) from the marine Pleistocene coral reef deposits bordering the Red Sea coast and dating to the last interglacial epoch (Marine Isotopic Substage 5e, MIS5e). Twenty-one species were identified, of which only three were previously known from the Pleistocene of the Red Sea (Lucilina sueziensis, Acanthopleura vaillantii and Acanthochitona penicillata). Eight are recorded as fossil for the first time. Six are described as new (Lucilina confusa n. sp., L. aqabaensis n. sp., L. aegyptiaca n. sp., L. colantonii n. sp., "Onithochiton" vandingeneni" n. sp., and Acanthochitona interglacialis n. sp.) and two are assigned at generic level (Callochiton sp. and Craspedochiton sp.). Four of these new species (Lucilina confusa n. sp., L. aegyptiaca n. sp., L. colantonii n. sp. and "Onithochiton" vandingeneni n. sp.) are still living in the Red Sea, bringing to 28 the number of extant species known from the Red Sea. These Pleistocene Red Sea assemblages represent the most diverse chiton fauna yet reported from any interglacial deposit worldwide.
本研究描述了来自红海沿岸海洋更新世珊瑚礁沉积物的石鳖动物群（软体动物门，多板纲），其年代可追溯到最后一个间冰期（海洋同位素亚阶段5e，MIS5e）。共鉴定出21个物种，其中只有3个物种此前在红海更新世中被发现过（苏伊士石鳖、瓦氏棘石鳖和毛石鳖）。有8个物种首次被记录为化石。有6个物种被描述为新物种（混淆石鳖新种、亚喀巴湾石鳖新种、埃及石鳖新种、科兰托尼石鳖新种、“鸥石鳖”万丁根尼新种和间冰期棘石鳖新种），还有2个物种被归到属一级（丽石鳖属物种和褶石鳖属物种）。这些新物种中有4个（混淆石鳖新种、埃及石鳖新种、科兰托尼石鳖新种和“鸥石鳖”万丁根尼新种）仍生活在红海中，使得已知的红海现存物种数量增至28种。这些更新世红海组合代表了全球所有间冰期沉积物中报道过的最多样化的石鳖动物群。
