In 1970s, zhao Xijin and Cheng Zhengwu collected some psittacosaur materials from Early Cretaceous Jiufotang Formation of Meileyingzi, Chaoyang, Liaoning, China (Sereno et al., 1988). Recently, some new psittacosaur materials were discovered from a neighboring area, Sihetun, Beipiao, Liaoning, but from an older lithostratigraphic unit: Yixian Formation. The new material was collected by the local farmer from the black shale of the lower part of Yixian Formation where a diverse fauna, including the famous "feathered" theropod Sinosauropteryx prima (Ji and Ji, 1996), pterosaur Eosipterus yangi (Ji and Ji, 1997), bird Protarchaeopteryx robusta (Ji and Ji, 1997), Confuciusornis sanctus (Hou et al., 1995) and Liaoningornis longiditris (Hou, 1996), and Anura (personal observation), was discovered. The fossil remain is housed in Mr. Liang Shikuan's collections. L is the prefix to the studied fossils of Mr. Liang.

The salamander fossils have been especially scarce in Mesozoic deposits (Estes, 1981). In China, there was only one reported fossil salamander, Procynops miocenicus, from the upper Miocene Shanwang Series in Shandong Province (Young, 1965). The age of Shanwang Series later was revised as early middle Miocene by Li et al. (1984). The herein described fossil salamander was found in Sajiaocheng, Huludao City, Liaoning Province, collected by geologist Mr. Chang Zhenglu from the Coal and Geological Bureau of Fuxin City. The collector provided the horizon of this salamander as Jiufotang Formation, which is accepted as Early Cretaceous in age (Hao et al., 1982; Jin, 1996). Some other fossil salamanders also have been found from the Mesozoic deposits in the western area of Liaoning Province and the northern area of Hebei Province, neither were reported nor described. This is the first described Mesozoic caudate amphibian in northeastern China. The herein described fossils are preserved on more than 30 slabs of shale, representing more than 20 individuals. The terminology of urodele osteology follows that of Duellman and Trueb (1986) and Estes (1978).
