摘要

来自东南亚的三叠纪海洋介形虫鲜为人知,导致在生命史的这一关键时期,人们对其在特提斯东部边缘的生物多样性产生了深刻的误读。在这里,我们描述了来自泰国中部乌泰他尼省的考帕塔维石灰岩的第一个晚三叠纪介形虫组合。它包括22个保存相对较差的物种,对它们的分类学进行了讨论,并增加了对三叠纪晚期海洋介形虫的科学理解。讨论了明显缺乏典型的三叠纪Metacopina和华丽的Bairdiidae。尽管一些被发现的物种可能是科学界的新物种,但现在描述它们还为时过早。特提斯西部和南部地区的Rhaetian群落共有两个物种,未来可能会确认其他共有物种,说明晚三叠纪介形虫类群的大规模分布。总的来说,这里描述的介形虫组合与为Khao Pathawi石灰岩提出的Norian Rhaetian时代一致。

Marine ostracods from the Khao Pathawi Limestone (Late Triassic), central Thailand

Triassic marine ostracods from south-eastern Asia are poorly known, leading to a profound misreading of their biodiversity on the eastern Tethys margin during this critical interval of the history of life. Here we describe the first Late Triassic ostracod assemblage from the Khao Pathawi Limestone exposed in Uthai Thani Province, central Thailand. It comprises 22 relatively poorly preserved species, their taxonomy is discussed and adds to the scientific understanding of marine ostracods during the Late Triassic. The noticeable lack of the archetypal Triassic Metacopina and ornate Bairdiidae is discussed. Although several of the recovered species might be new to science, it is premature to describe them. Two species are shared with Rhaetian communities described from western and southern Tethyan localities and additional shared species may be confirmed in the future, illustrating the largescale distribution of ostracod taxa during the Late Triassic. Overall, the ostracod assemblage described here is in line with the Norian-Rhaetian age proposed for the Khao Pathawi Limestone.

期刊介绍: La Revue de micropaléontologie publie 4 fois par an des articles de intérêt international, consacrés à tous les aspects de la micropaléontologie. Les textes, en anglais ou en français, sont des articles originaux, des résultats de recherche, des synthèses et mises au point, des comptes rendus de réunions scientifiques et des analyses de ouvrages. La revue se veut résolument ouverte à tous les aspects de la micropaléontologie en accueillant des travaux traitant de la systématique des microfossiles (et de leurs équivalents actuels), des bactéries aux microrestes de vertébrés, et de toutes leurs applications en sciences biologiques et géologiques.
