Azhdarchid pterosaur from the Upper Cretaceous (Turonian) of Utah, USA

Azhdarchids are large pterosaurs from the Cretaceous, known mostly from fragmentary skeletal material. Here, we describe an azhdarchid pterosaur (OMNH 22014) collected from the middle Turonian Smoky Hollow Member of the Straight Cliffs Formation, Utah. The specimen is a partial metacarpal IV, with three-dimensional preservation including the distal half of the shaft and the distal condyles. The specimen is from a skeletally mature adult, with a maximum wingspan estimate of 4.7 m.
