Abstract. The Messinian Salinity Crisis and its precursor events have been the greatest environmental perturbation of the Mediterranean Sea to date, offering an opportunity to study the response of marine ecosystems to extreme hydrological change and a large-scale biological invasion. The restriction of the marine connection between the Mediterranean and the Atlantic Ocean already since the Tortonian–Messinian boundary resulted in stratification of the water column and increase water temperature and salinity variations. Here, we present a unified and revised marine fossil record of the Mediterranean that covers the Tortonian stage, the pre-evaporitic Messinian and the Zanclean stage and encompasses 22988 occurrences of calcareous nannoplankton, dinoflagellates, foraminifera, corals, ostracods, bryozoans, echinoids, mollusks, fishes, and marine mammals. This record adheres to the FAIR principles, it is updated in terms of taxonomy, and it follows the currently accepted stratigraphic framework. Based on this record, knowledge gaps are identified, which are due to spatiotemporal inconsistencies in sampling effort and the distribution of sedimentary facies, and the inherent differences in the preservation potential between the groups. Additionally, sampling bias in old records may have distorted the record in favor of larger, more impressive taxa within groups. This record is now ready to be used to answer both geological and biological questions, and is amendable when new fossil data are brought to light.

墨西拿盐度危机前后地中海海洋化石记录的修订

摘要。麦西尼亚盐度危机及其前兆事件是地中海迄今为止最严重的环境扰动，为研究海洋生态系统对极端水文变化和大规模生物入侵的反应提供了机会。自托尔托阶-麦西尼亚边界以来，地中海和大西洋之间的海洋联系受到限制，导致水柱分层，增加水温和盐度变化。在这里，我们提出了统一和修订的地中海海洋化石记录，涵盖托尔托阶、蒸发前墨西阶和赞克林阶，并包含 22988 个钙质微浮游生物、甲藻、有孔虫、珊瑚、介形类、苔藓虫、海胆类、软体动物的化石记录、鱼类和海洋哺乳动物。该记录遵循 FAIR 原则，在分类学方面进行了更新，并遵循当前公认的地层框架。根据该记录，确定了知识差距，这是由于采样工作和沉积相分布的时空不一致以及各组之间保存潜力的固有差异造成的。此外，旧记录中的抽样偏差可能会扭曲记录，有利于群体内更大、更令人印象深刻的分类单元。该记录现已准备好用于回答地质和生物学问题，并且当新的化石数据曝光时可以进行修改。
