Pterosaurs Taxonomy


The Pterosauria are classified firmly into two suborders - the long tailed Rhamphorhynchoids and the short tailed Pterodactyloids.  The classification of each suborder is open to debate, but for the purpose of this presentation, a modified version of the phylogeny of David Unwin's model has been used.  Depending upon the key characteristics used to interpret the Pterosaur associations, there are also other possible and valid taxonomic groupings.

This scheme was updated in February 2011 and may be modified by subsequent discoveries.
