| 摘 要： | 在辽西凌源热水汤地区新发现一套夹于中酸性和酸性火山岩中的含蝾螈等化石的沉积层,可以称之为热水汤层.该层所产蝾螈化石特征类似于内蒙宁城县山头乡道虎沟地区海房沟组的初螈类,其伴生植物化石组合显示介于中侏罗世海房沟组至早白垩世义县组之间的特征,其时代置于中侏罗世晚期较为合适.同时,将热水汤层及其上覆、下伏酸性和中酸性火山岩一并划归髫髻山组.

| Abstract: | New salamander fossil bearing beds were found from a suite of acid intermediate and acid volcanic rocks in Reshuitang area near Lingyuan,Western Liaoning Province.The fossil beds are inferred as to Reshuitang Bed.The salamander fossils are similar to those of Chunerpeton from the Haifanggou Formation exposed at Daohugou,Ningcheng County,Inner Mongolia.The plant fossil assemblage shows their feature situated between Middle Jurassic Haifanggou and Early Cretaceous Yixian Formations.Its age refers to the late stage of Middle Jurassic.Therefore,the Reshuitang Bed,together with the overlying and underlying acid and acid intermediate volcanic rocks,is included into the Tiaoqishan Formation. |

| Keywords: | late Middle Jurassic Tiaoqishan Formation salamander fossil bearing strata Reshuitang Lingyuan |
