The taxonomy and phylogeny of Diopecephalus kochi (Wagner, 1837) and ‘Germanodactylus rhamphastinus’ (Wagner, 1851)

Geometric morphometric analysis of prepubes and a cladistic analysis of the Pterosauria elucidate plesiomorphic and apomorphic conditions for basal Jurassic pterodactyloids.


The specimens from the Solnhofen Limestone of southern Germany support the interpretation that the cranial crest developed late in ontogeny, probably as the individual approached skeletal and/or sexual maturity.

New Material of Zhenyuanopterus (Pterosauria) from the Early Cretaceous Yixian Formation of Western Liaoning

The pectoral girdle, robust forelimb and weak hindlimb of the new material together with data from the holotype of Zhenyuanopterus indicate that this taxon spent less time on land than in the sky or other ecological niches such as forests and cliffs.

Pterodactylus scolopaciceps Meyer, 1860 (Pterosauria, Pterodactyloidea) from the Upper Jurassic of Bavaria, Germany: The Problem of Cryptic Pterosaur Taxa in Early Ontogeny

A cladistic analysis demonstrates that Aerodactylus is distinct from PterodactYLus, but close to Cycnorhamphus Seeley, 1870, Ardeadactylu Bennett, 2013a and Aurorazhdarcho Frey, Meyer and Tischlinger, 2011, consequently the new genus AerodACTylus was erected to accommodate it.

Abstract The immense size of many pterosaurs is now well known to academics and laymen alike, but truly enormous forms with wingspans more than twice those of the largest modern birds were not
