Permian brachiopods from the Khao Hin Kling Area near Phetchabun, north-central Thailand

Abstract

This paper deals with Permian brachiopods collected from 7 localities in the Tak Fa Formation of the Rat Buri Group, developed in the Khao Hin Kling area, about 50 km southwest of Phetchabun. Twenty one species within seventeen genera are described and discussed. Of them four species, Acosarina kanmerai, Orthotetina ruchae, Haydenella granti and Nolothyris sakagami, are newly established ones. The Khao Hin Kling brachiopod fauna ranges from the Middle to early Late Permian. The faunal elements contain close affinities to those of the central and southern Tethyan realms.
