A Late Miocene palaeobiogeographic framework of the Mediterranean-Atlantic Region, based on a comparative study of the continental shelf ostracod assemblages collected from a section in the Saïss Basin, northwestern Morocco, is proposed. Distribution data and statistical analyses allowed to identify six palaeoecoregions. Five of these units, that is South European Atlantic Shelf, Saharan Upwelling, Adriatic Sea, Western Mediterranean and Alboran Sea, were identified according to the ecoregions used in modern biogeographic frameworks. For the easternmost part of the Proto-Mediterranean basin a “Late Miocene Southeastern Mediterranean” palaeoecoregion is proposed. The Tortonian-Messinian palaeobiogeography of the so-called “Miocene European-West African Province”, preceding the onset of the Messinian Salinity Crisis, was under the influence of the relationships between Atlantic and Proto-Mediterranean biota in tropical, subtropical and possibly warm temperate waters.

地中海-大西洋地区晚中新世古生物地理学：基于摩洛哥西北部陆架介形类组合的分析

基于对从摩洛哥西北部萨伊斯盆地采集的大陆架介形类组合的比较研究，提出了地中海-大西洋地区晚中新世古生物地理框架。分布数据和统计分析可以识别六个古生态区。其中五个单位，即南欧大西洋陆架、撒哈拉上升流、亚得里亚海、西地中海和阿尔沃兰海，是根据现代生物地理框架中使用的生态区确定的。对于原始地中海盆地的最东部，提出了一个“晚中新世东南地中海”古生态区。在麦西尼亚盐度危机爆发之前，所谓的“中新世欧洲-西非省”的托尔托阶-麦西尼亚古生物地理学受到大西洋和原始地中海热带、亚热带和可能暖温带生物群之间关系的影响水域。
