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,[1] but later, after a cladistic analysis, suggested that it was more basal than Azhdarchidae proper, but was still in the same superfamily.[2] Lü, Unwin and colleagues later placed in in a family of basal azhdarchoids, the Chaoyangopteridae.[3]
