Comments

Taxonomy from Fossilworks.org.

Synonyms: Perleidus eurylepidotrichia Liu 2002,  Perleidus yangtzensis Su 1981.

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 yangtzensis (Su, 1981): "Maxilla relatively short and broad, length of its post-orbital part approximately 2/ 5 of the maxillary length; scales well ornamented with ridges and their hinder margin serrated."

Line drawing from Jin et al. 2003, p. 177:

Identified by oilshale based on the head bones and the characteristic serrated and ornamented scales.
