"Eoazhdarcho" (meaning "dawn "Azhdarcho") is a genus of azhdarchoid pterodactyloid pterosaur. It was found in the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. It is based on GMN-03-11-02, a partial skeleton and lower jaw, and is distinguished from other pterosaurs by the proportions of its bones. It was relatively small by azhdarchid standards, with a wingspan of about 1.6 meters (5.2 feet). Its describers first assigned it to the Azhdarchidae, and compared it to "Azhdarcho",cite journal |last=Lü |first=Junchang |coauthors=and Qiang Ji |year=2005 |title=New azhdarchid pterosaur from the Early Cretaceous of western Liaoning |journal=Acta Geologica Sinica |volume=79 |issue=3 |pages=301–307 ] but later, after a cladistic analysis, suggested that it was more basal than Azhdarchidae proper, but was still in the same superfamily.cite journal |last=Lü |first=Junchang |coauthors=and Qiang Ji |year=2006 |title=Preliminary results of a phylogenetic analysis of the pterosaurs from western Liaoning and surrounding area |journal=Journal of the Paleontological Society of Korea |volume=22 |issue=1 |pages=239–261 |url=http://cactus.dixie.edu/jharris/Lu&Ji_ptero_phylogeny.pdf |accessdate=2007-03-10 ] Lü, Unwin and colleagues later placed in in a family of basal azhdarchoids, the Chaoyangopteridae.Lü, J., Unwin, D.M., Xu, L., and Zhang, X.
