| 摘 要： | 根据一具保存有皮肤印痕的完整骨骼化石，描述了采自辽宁北票黄半吉沟晚侏罗世—早白垩世义县组下部的一新的无尾两栖类，并确立其为一新属、新种—孟氏大连蟾(Dalianbatrachus mengigen．et．sp．nov．)。该化石以其尾杆骨较长，超过荐前椎的总长度，胫腓骨与股骨等长和跗节长小于胫腓骨长的一半而区别于其它两栖类。

| Abstract: | Based on the study of a well preserved skeleton with the impression of skins, a new taxon of Anura is described from the Upper Jurassic-Lower Cretaceous, lower part of Yixian Formation of Huangbanjigou, Beip-iao of Liaoning,China. The specimens are assigned to a new genus and species- (Dalianbatrachus mengi gen. et. sp. nov.) . The new taxon is characterized by the following features: urostyle is longer than the total length of presacrals; tibiofibula is as long as femur; the tarsus is less than tibiofibula for two times in length, which differs from other known Anuras. |
