Comments

Synonym: Zhangina cylindrica Liu, 2002; Plesioperleidus jiangsuensis Qian 1997

From the sediments of the Lower Qinglong Formation, a number of species (Plesioperleidus, Zhangina, Suis, Jurongia, Quingshania, Peia .. ) have been described, which are difficult to distinguish at first sight and are usually traded either as "Plesioperleidus" or as "Lepidotes".
Diagnosis for Zhangina jiangsuensis Qian et al., 1997 by Jin et al. p. 182: "Maxilla relatively slender ,length of its post-orbital part approximately 1/ 3 of the maxillary length ; scales smooth , with some exceptions slightly ornamented with ridges and with serrated hinder margin."

Line drawing of the head by Jin et al. 2003, p. 174:

Identified by oilshale based on head bones, dentition and squamation.
