Douzhanopterus
''Douzhanopterus'' is an extinct genus of monofenestratan pterosaur from the Late Jurassic of Liaoning, China. It contains a single species, ''D. zhengi'', named by Wang ''et al.'' in 2017. In many respects, it represents a transitional fossil, transitional form between basal (phylogenetics), basal pterosaurs and the more specialized pterodactyloidea, pterodactyloids; for instance, its tail is intermediate in length, still being about twice the length of the femur but relatively shorter compared to that of the more basal Wukongopteridae. Other intermediate traits include the relative lengths of the cervical vertebrae, neck vertebrae and the retention of two, albeit reduced, phalanx bones in the fifth digit of the foot. Phylogenetics, Phylogenetically, ''Douzhanopterus'' is nested between the wukongopterids and ''Propterodactylus'', which is similar to ''Douzhanopterus'' in many respects but approaches pterodactyloids more closely elsewhere.

Propterodactylus
''Propterodactylus'' (meaning "before ''Pterodactylus''") is an extinct genus of Transitional fossil, transitional monofenestratan pterosaurs from the Late Jurassic Painten Formation of Germany. The genus contains a Monotypic taxon, single species, ''P. frankerlae'', known from a complete articulated skeleton. Before its naming, ''Propterodactylus'' was referred to as the "Painten " in the scientific literature. Discovery and naming The ''Propterodactylus'' holotype specimen, Dinosaurier Museum Altmühltal, DMA-JP-2011/006, was discovered in April 2011 in the Rygol lime works quarry of the Painten Formation (Ulmense subzone) near Painten in Bavaria, Germany. The nearly-perfect specimen consists of an Joint, articulated complete skeleton with preserved soft tissues. In 2024, Frederik Spindler Species description, described ''Propterodactylus frankerlae'' as a new genus and species of monofenestratan pterosaur based on these fossil remains. The Genus, generic name, ''Propterodact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
