Kryptodrakon
''Kryptodrakon'' is an extinct genus of pterodactyloid pterosaur from the Middle–Late Jurassic boundary of China, with an age of approximately 162.7 million years.〔 It is known from a single type species, ''Kryptodrakon progenitor''. When it was named in 2014, ''Kryptodrakon'' was the basalmost and oldest pterodactyloid known.
==Discovery and naming==
In 2001, pterosaur bones were discovered in Xinjiang by Chris Sloan. The bones were first identified as those of a theropod; palaeontologist James Clark later recognized their pterosaurian nature.
In 2014, Brian Andres, Clark and Xu Xing named and described the type species ''Kryptodrakon progenitor''. The generic name means ''hidden dragon'' from Greek κρυπτός, ''kryptos'' (''hidden''), and δράκων, ''drakon'' (''dragon''). The name alludes to the film ''Crouching Tiger, Hidden Dragon''. The specific name ''progenitor'' means ''ancestor'' or ''founder of a family'' in Latin, and refers to the animal's status as the most basal member of the Pterodactyloidea.〔
The holotype, IVPP V18184, was uncovered in a layer of the Shishugou Formation dating from the Callovian–Oxfordian and having a minimum age of 161 million years. It consists of a partial skeleton lacking the skull. It contains fragments of both wings including the right fourth metacarpal, parts of the shoulder girdle and the second sacral vertebra. The bones were not articulated but were discovered in a small area of thirty square centimetres, at a considerable distance from other fossil remains, and thus likely represent a single individual. The bones were largely preserved three-dimensionally, without strong compression. The holotype probably was an adult individual.〔
