Dec 7, 2021 · The proportions and possible motions of the skeleton of the giant azhdarchid pterosaur Quetzalcoatlus are reconstructed, finding that despite the animal’s great size, the hind limb to torso length ratio is the greatest for all known pterosaurs.

Dec 14, 2021 · 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 described. This shortfall is addressed here through a full morphological description of Quetzalcoatlus and the other pterosaur material of Big Bend National Park, Texas.

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 neck could swing left and right through an arc of ca. 180°.
