This study presents the first record of Early Permian alatoconchid bivalves from Thailand, the Erawan section, in the north of Loei fold belt with prolific fusulines in association with gastropods, and brachiopods. Fusuline taxa are dominated by sp. with sp., cf. , sp., sp., sp., sp., , sp. and others, indicating an Artinskian age. Fusuline wackestone with common, well-preserved smaller foraminifers, sp. and ostracods indicates a restricted lagoon environment with low to moderate water circulation. These fossils, along with well-preserved, articulated alatoconchids in life-position, suggest the autochthonous nature of the deposits in an intertidal environment.

印度支那地体黎褶带晚西苏拉世和瓜达鲁普世（早至中二叠世）含乌贝类灰岩的微相及古环境

这项研究首次记录了来自泰国爱侣湾地区、黎府褶皱带北部的早二叠世双壳类双壳类动物，其中有大量与腹足动物和腕足动物相关的fusulines。 Fusuline类群以sp为主。与 sp.，参见, sp., sp., sp., sp., , sp.等，表明阿廷斯基时代。 Fusuline wakestone 与常见的、保存完好的较小有孔虫，sp。介形类表明泻湖环境受到限制，水循环较低至中等。这些化石以及保存完好、处于生命状态的有关节的阿拉托贝类，表明潮间带环境中沉积物的原生性质。
