The Dimorphodon was a small pterosaur that lived during the Early Jurassic period. It had a wingspan of around 4 feet and was one of the earliest known pterosaurs. Dimorphodon had a short, broad head and a long, pointed jaw with sharp teeth, which it likely used to catch fish or insects. It had a bony crest on its head, which may have been used for display or to control flight.
Dimorphodon had a short tail and long fingers with elongated fourth digit, which supported its flight membrane (patagium). Dimorphodon was a quadrupedal animal when on ground, and it walked on four long legs, which were adapted for grasping. The name Dimorphodon means “two-form tooth”, referring to the presence of two distinct types of teeth in its jaw.
