摘要在塞尔维亚西北部Valjevo镇地区新发现的二叠纪-三叠纪界线（PTB）段，记录了微动物、沉积学和地球化学调查的详细结果。在上二叠统“沥青灰岩”组中发现了种类丰富的微化石（牙形刺、有孔虫和介形虫），从而确定了长兴期Hindeodus praeparvus牙形刺带。本文是该地区以及塞尔维亚所有地区最新二叠纪地层的第一份报告，其中PTB段沉积物已成为生物地层学和地球化学复杂/综合研究的一部分。
Abstract Detail results of microfaunal, sedimentological and geochemical investigations are documented from a newly discovered section of the Permian–Triassic boundary (PTB) interval in the area of the town of Valjevo (northwestern Serbia). The presence of various and abundant microfossils (conodonts, foraminifers, and ostracodes) found in the Upper Permian “Bituminous limestone” Formation enabled a determination of the Changhsingian Hindeodus praeparvus conodont Zone. This paper is the first report of latest Permian strata from the region, as well as from all of Serbia, where the PTB interval sediments have been part of a complex/integrated study by means of biostratigraphy and geochemistry.
