Eoazhdarcho liaoxiensis GMN-03-11-02 (Lü and Ji 2005) Aptian, Early Cretaceous was originally considered a basal azhdarchid in the lineage of Chaoyangopterus and Quetzalcoatlus. A later analysis by Lü and Ji (2006) nested it close to Pteranodon. Here Eoazhdarcho was derived from No. 13, Aurorazhdarcho (see below) and was a sister to Eopteranodon.

Overall much larger than No. 13, the mandible of Eoazhdarcho was reported as toothless.

The scapula was longer than the coracoid. The humerus was tongue-shaped and more robust. The metatacarpals were longer than the ulna/radius. Fingers I-III were more gracile. The proportions of the wing phalanges are unchanged relative to the rest of the forelimb.

The tibia was relatively longer, coincident with the elongation of the metacarpus and manual 4.1.

It is likely that Eopteranodon and Eoazhdarcho are congeneric. Data with greater resolution should be able to solve this problem.
