Abstract

In the shallow-marine deposits of the Early Miocene (Aquitanian – Burdigalian) Fırat Formation exposed in the Eğil district of Diyarbakır, SE Turkey, three oyster species such as Ostrea edulis (Linnaeus, 1758), Magallana gryphoides (Schlotheim, 1820), and Hyotissa hyotis (Linnaeus, 1758) were recorded for the first time. The specimens collected include four individuals of O. edulis and three individuals of M. gryphoides from the Sağlam village area, and one individual of H. hyotis from the Sarıca village area in Eğil. These specimens were found in the yellow-limestone facies and beige-white marl facies, which represent the thickest and largest sections of the Fırat Formation. For the Sağlam village area, O. edulis suggests a littoral environment with excessive detrital inputs, ranging from medium to shallow depths, and a warm subtropical climate. The O. edulis display a slender, small, and comparatively regular morphology, suggesting a preference for stable habitats commonly found in coastal regions with minimal environmental variability. Similarly, the presence of the fossil species indicates littoral environments characterized by nearshore shallow depths, low-energy conditions, normal salinity, and warm subtropical climatic conditions for M. gryphoides. For the Sarıca village area, H. hyotis is linked to reef and peri-reef environments, along with shallow tropical-subtropical marine paleoenvironments at depths of up to 50 m. Overall, this study presents novel information about the paleoecological distribution of Early Miocene oysters and their first records in the Eğil district.

从土耳其东南部迪亚巴克尔 Fırat 地层浅海沉积物中的早中新世牡蛎洞察古环境
在土耳其东南部迪亚巴克尔埃吉尔地区出露的早中新世(阿奎坦期-布迪加里期)费拉特地层浅海沉积中,首次记录了三个牡蛎物种,如 Ostrea edulis (Linnaeus, 1758)、Magallana gryphoides (Schlotheim, 1820) 和 Hyotissa hyotis (Linnaeus, 1758)。采集到的标本包括萨格拉姆(Sağlam)村地区的四只 O. edulis 和三只 M. gryphoides,以及埃吉尔(Eğil)萨勒卡(Sarıca)村地区的一只 H. hyotis。这些标本均发现于黄色石灰岩层和米色-白色泥灰岩层,它们代表了菲拉特地层最厚和最大的部分。对于萨格拉姆村地区来说,O. edulis 表明该地区属于沿岸环境,从中层到浅层都有过多的碎屑输入,并且属于温暖的亚热带气候。O. edulis 的形态纤细、小巧且相对规则,表明其偏好环境变化极小的沿海地区常见的稳定栖息地。同样,化石物种的出现也表明 M. gryphoides 所处的沿岸环境具有近岸浅水、低能量条件、正常盐度和温暖的亚热带气候条件等特点。就 Sarıca 村地区而言,H. hyotis 与珊瑚礁和近珊瑚礁环境以及最深达 50 米的热带-亚热带浅海古环境有关。
