Examples of Rhamphorhyncoids-Page 1


This Rhamphorhyncoid type pterosaur appears to be one of the few pterosaurs that did not feed on marine organisms. When specimens of Dimorphodon (To hear pronunciation choose: Mac/Win) are found they appear to be always associated with terrestrial fossils.

Like all Rhamphorhyncoids, they are characterized by a large head and tail. The tail may have been used in balancing while Dimorphodon was on the ground. It has been suggested that Dimorphodon was a very capable runner due the length of the fibula and tibula.

The jaws contain two types of teeth, from which the name Dimorphodon is derived. The front teeth are longer than the rear and may have been used to grab prey while the rear were more suited to shredding.
