Zhejiangopterus linhaiensis, originating from Late Cretaceous China, represents a significant azhdarchid discovery and is considered one of the most thoroughly documented. Initially, the holotype, described in 1994 by Cai and Feng, comprised only a partial skull. However, subsequent findings included six more specimens that were notably more complete.

Despite the general similarities among azhdarchids, there were still some differences within the group. For instance, the Romanian taxa exhibited a robust, short-necked structure, while the one in question lacked a bony crest. Compared to its relatives, this particular species is relatively moderate in size, boasting a wingspan of approximately 3.5 meters.

Zhejiangopterus was initially categorized as a member of the Nyctosauridae by the original researchers because of its similarities to two edentulous pterosaurs with well-described characteristics, Pteranodon and Nyctosaurus, with Zhejiangopterus displaying a closer resemblance to the latter. At the time of its initial description, there was a lack of data available on Quetzalcoatlus. However, in 1997, it was concluded that Zhejiangopterus was more closely related to the giant American form, Quetzalcoatlus, and therefore belonged to the Azhdarchidae. It stands as the only known azhdarchid with such comprehensive skeletal material.
