Harpactognathus (meaning "seizing/grasping jaws") was a genus of pterosaur found in the Late Jurassic-age Morrison Formation of Albany County, Wyoming, USA. It is based on NAMAL 101, a partial skull consisting of the snout, recovered from near Bone Cabin Quarry in 1996. The species name honors Joe Gentry, a volunteer for the Western Paleontological Laboratories, in Lehi, Utah.[1]
Its describers found it to be most similar to Scaphognathus among pterosaurs, albeit substantially larger (estimated skull length of 280-300 mm (11-12 in), estimated wingspan of 2.5 m (8.2 ft)). Because of the similarity, Harpactognathus was assigned to the subfamily Scaphognathinae of the family Rhamphorhynchidae. This genus is also notable for having a low bony crest run all the way to the tip of the beak (pterosaur bone crests usually don't go all the way to the tip), and for being the oldest known Morrison Formation pterosaur, having been found in the Salt Wash Member.[1]
[edit] Paleobiology
As a rhamphorhynchid, Harpactognathus would have been an aerial predator of small prey.
