本文记述了一新的非翼手龙科基底翼龙--潘氏长城翼龙属（Changchengopteruspani gen. etsp. nov.）是建立在一个几乎完整的颅后骨骼的基础上的。这个新分类群的特征是尾椎的前关节突、后关节突和血弓相对较短;肱骨有一个近三角形的胸三角嵴;肢体成分的长度按以下顺序减少：尺骨>翼指骨2 >翼指骨3 =翼指骨1 >肱骨>胫骨>股骨>翼掌骨。系统发育分析表明，长城翼龙属为喙嘴类的基部成员，与矛颌龙属的亲缘关系较近。含长城翼龙沉积物的地质时代不晚于晚侏罗世末，可能为中侏罗世。
A new basal non-pterodactyloid pterosaur, Changchengopterus pani gen. et sp. nov., is erected, on the basis of a nearly complete postcranial skeleton. The new taxon is distinguished by relatively short extensions of the prezygapophyses, postzygapophyses and haemal arches of the caudal vertebrae; a humerus that has a subtriangular deltopectoral crest; limb elements that decrease in length in the following order: ulna > wing-phalange 2 > wing-phalange 3 = wing-phalange 1 > humerus > tibia > femur > wing-metacarpal. Phylogenetic analysis suggests that Changchengopterus is a basal member of rhamphorhynchoids, and more closely related to Dorygnathus than to other rhamphorhychoids. The geological age of the Changchengopterus-bearing sediments is no latter than the end of the Late Jurassic and it is possible Middle Jurassic.
