摘要

对斯洛文尼亚外迪纳里德斯山脉马索雷地段上二叠统和二叠统-三叠统过渡地层中的梭形目动物群进行了研究。共鉴定出 13 属 20 种，分别属于 Palaeocopida、Platycopida 和 Podocopida 目，并绘制了图解。所有发现的桡足类都属于浅海类群。区分了二叠纪最上层的古老动物群和二叠纪-三叠纪边界地层的年轻动物群。从二叠纪贝勒洛芬地层中获得的动物群与占据陆架海底的 "底栖介形类 Eifelian Mega-assemblage "相对应。这项研究首次报告了斯洛文尼亚二叠纪最上层和二叠纪-三叠纪界线区间的梭形纲动物群。所发现的浮游动物群显示出明显的动物变化，并与古地层西部其他一些邻近地点（如意大利的布拉、塞尔维亚的科米里奇和匈牙利的比克山脉）的地层等同动物群具有相似性，因而具有重要的古生物地理学意义。

FIRST REPORT ON THE UPPERMOST PERMIAN OSTRACODS FROM THE MASORE SECTION (EXTERNAL DINARIDES), SLOVENIA

The ostracod assemblages from the Upper Permian and Permian-Triassic transitional strata of the Masore section in the External Dinarides (Slovenia) were studied. Altogether 13 genera and 20 species of the orders Palaeocopida, Platycopida and Podocopida are identified and illustrated. All recovered ostracods belong to shallow marine taxa. The older fauna from the uppermost Permian and the younger fauna from the Permian-Triassic boundary strata are distinguished. The obtained fauna from the Permian Bellerophon Formation corresponds to the “benthonic ostracod Eifelian Mega-assemblage” occupying the shelf sea floors. This study presents the first report of ostracod faunas from the uppermost Permian and Permian-Triassic boundary interval of Slovenia. The recovered ostracod fauna display a distinct faunal change and yield important paleobiogeographic implications as it reveals similarity with stratigraphical equivalent faunas from some other neighboring localities in the western Paleotethys, such as Bulla in Italy, Komirić in Serbia, and the Bükk Mountains in Hungary.

期刊介绍： The Rivista Italiana di Paleontologia e Stratigrafia was founded in 1895. It publishes original papers dealing with all fields of paleontology and of stratigraphy, from Italy and the Mediterranean to the Tethys, as well across the globe from China to North America.
