The Pterosauria cladogram is a flexible structure depending on the interpretation of key features.  This version is based upon a composite of ideas from researchers at universities around the world. 

The Rhamphorhynchoid pterosaurs are classified as pterosaurs with a short wing metacarpal and a long tail.  There are a few exceptions to this rule, but it is generally true.

The Pterodactyloid pterosaurs are classified as pterosaurs with a long wing metacarpal and a short tail.

Below is another interpretation of the relationship of the Rhamphorhynchoid pterosaurs.
