Quetzalcoatlus is the largest flying organism ever known and one of the most familiar
pterosaurs to the public. Despite a half century of interest, it remains very incompletely …

We developed a three-dimensional, biomechanical computer model of the 36 major pelvic
limb muscle groups in an ostrich (Struthio camelus) to investigate muscle function in this, the …

The defining masterwork on the evolution of reptiles. Over 300 million years ago, an early
land vertebrate developed an egg that contained the embryo in an amnion, allowing it to be …

The last common ancestor of birds and crocodylians plus all of its descendants (clade
Archosauria) dominated terrestrial Mesozoic ecosystems, giving rise to disparate body …

The Solnhofen pterosaurs Pterodactylus antiquus, Aerodactylus scolopaciceps,
Diopecephalus kochi, Germanodactylus cristatus and Germanodactylus rhamphastinus all …

Pterodactyloid pterosaurs are widely interpreted as terrestrially competent, erect-limbed
quadrupeds, but the terrestrial capabilities of non-pterodactyloids are largely thought to have …

We reconstruct the proportions and possible motions of the skeleton of the giant azhdarchid
pterosaur Quetzalcoatlus. The neck had substantial dorsoventral mobility, and the head and …

The moment arm of a muscle defines its leverage around a given joint. In a clinical setting,
the quantification of muscle moment arms is an important means of establishing the …

New discoveries on the ichnological site known as “the Pterosaur Beach of Crayssac”(lower
