A large pterodactyloid pterosaur from the Late Cretaceous Ferron Sandstone of Utah

Abstract

AbstractThree associated incomplete wing bones of a large pterodactyloid pterosaur from the Ferron Sandstone Member of the Mancos Shale Formation of Utah are described. Based on the morphology of the bones’ articular ends, the specimen is referred to the Pteranodontoidea. Associated ammonites indicate that the specimen's age is Middle Turonian, so it adds to the sparse worldwide record of Turonian pterosaurs. The record of pteranodontoid pterosaurs in the Western Interior Seaway of North America is reviewed, and it is suggested that pteranodontoids were not diverse.
