Abstract

Eleven Ordovician conodont species of nine genera from the Ban Tha Kradan area of western Thailand are described and illustrated here for the first time. Based on similar lithological features and stratigraphical range, the upper part of Tha Manao Formation in the Ban Tha Kradan area of Kanchanaburi Province is amended and assigned to the Pa Kae Formation. The Scolopodus striatus Assemblage Zone is recognized in the revised Tha Manao Formation in the Ban Tha Kradan area. Based on conodonts and macrofossils, the Tha Manao Formation in western Thailand is assigned to the upper Floian to Darriwilian, and the conformably overlying Pa Kae Formation to the Sandbian to lower Katian.

来自泰国西部Ban Tha Kradan地区的奥陶系牙形刺

本文首次描述并展示了泰国西部班塔克拉丹（Ban Tha Kradan）地区9个属的11个奥陶纪锥齿类物种。根据相似的岩性特征和地层范围，对尖竹汶府 Ban Tha Kradan 地区的 Tha Manao 地层上部进行了修正，并将其归入 Pa Kae 地层。在修订后的班塔克拉丹地区塔玛瑙地层中，确认了Scolopodus striatus集合带。根据锥齿动物和大型化石，泰国西部的塔玛瑙地层被归入上弗洛统至达里维利统，而顺承上覆的帕猜地层则被归入砂比亚统至下卡梯统。

期刊介绍： Palaeoworld is a peer-reviewed quarterly journal dedicated to the study of past life and its environment. We encourage submission of original manuscripts on all aspects of palaeontology and stratigraphy, comparisons of regional and global data in time and space, and results generated by interdisciplinary investigations in related fields. Some issues will be devoted entirely to a special theme whereas others will be composed of contributed articles. Palaeoworld is dedicated to serving a broad spectrum of geoscientists and palaeobiologists as well as serving as a resource for students in fields as diverse as palaeobiology, evolutionary biology, taxonomy and phylogeny, geobiology, historical geology, and palaeoenvironment. Palaeoworld publishes original articles in the following areas: •Phylogeny and taxonomic studies of all fossil groups •Biostratigraphy, chemostratigraphy, chronostratigraphy •Palaeoecology, palaeoenvironment and global changes throughout Earth history •Tempo and mode of biological evolution •Biological events in Earth history (e.g., extinctions, radiations) •Ecosystem evolution •Geobiology and molecular palaeobiology •Palaeontological and stratigraphic methods •Interdisciplinary studies focusing on fossils and strata
