sentences:  A detailed phylogenetic analysis of Liaoning pterosaurs published by Lü Junchang and Ji Qiang in 2006 found it instead to be a basal azhdarchoid of no particular familial affiliation.However, subsequent analysis by Lu and Unwin found that within the Azhdarchoidea it formed a clade with several other forms such as "Jidapterus" and "Shenzhoupterus", which they named Chaoyangopteridae.Wang and Zhou, however, stated in 2006 that "Chaoyangopterus" was a member of the Pteranodontidae and that "Jidapterus", "Eoazhdarcho" and "Eopteranodon" are subjective junior synonyms of the former.
