A giant pterosaur (Reptilia: Archosauria) from the Judith River (Oldman) Formation of Alberta
Abstract
A specimen discovered in the Judith River Formation, Dinosaur Provincial Park, documents the presence of a giant pterosaur in Alberta during Campanian times. The element lacks both ends, but is probably a femur. The size suggests that the wingspan of the animal from which it was derived would have been about 13 m. A diagnostic vertebra from a smaller specimen demonstrates that the giant pterosaur is probably Quetzalcoatlus.
Résumé
Un spécimen découvert dans la formation Judith River, au Parc provincial des Dinosaures, renseigne sur la présence d'un ptérosaure géant en Alberta durant les temps campagniens. Les deux extrémités de l'ossement manquent, mais il s'agit probablement d'un fémur. La dimension indique que l'envergure des ailes de l'animal qui aurait fourni cet ossement serait environ de 13 m. Une vertèbre caractéristique provenant d'un plus petit spécimen permet d'affirmer que ce ptérosaure est probablement le Quetzalcoatlus. [Traduit par le journal]
