Rhamphorhynchidae is a group of early pterosaurs named after Rhamphorhynchus, that lived in the Late Jurassic.
[10] Members of the group possess no more than 11 pairs of teeth in the rostrum, a deltopectoral crest that is constricted at the base but expanded at the distal end, and a bent phalange on the fifth toe.
The broad-tipped skulls of scaphognathines held fewer teeth which were widely spaced and vertically oriented in the jaw.
[12] The cladogram (family tree) of rhamphorhynchids below is the result of a large phylogenetic analysis published by Andres & Myers in 2013.
