Kryptodrakon is an extinct genus of pterodactyloid pterosaur from the Middle to Late Jurassic with an age of approximately 162.7 million years.

[3] In 2014, Brian Andres, Clark and Xu Xing named and described the type species Kryptodrakon progenitor.

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 bones were not articulated but were discovered in a small area of 30 square centimeters (4.7 sq in), at a considerable distance from other fossil remains, and thus likely represent a single individual.

[1] The main author performed a cladistic analysis, the most extensive ever published about the Pterosauria and providing clade definitions for most pterosaur groups previously undefined.

A supposedly older pterodactyloid, a partial jaw referred to the group Ctenochasmatidae, had been described from the Middle Jurassic of the UK.
