Name: Cryodrakon ‭(‬Cold dragon‭)‬.
Phonetic: Kry-oh-dray-kon.
Named By: D.‭ ‬Hone,‭ ‬M.‭ ‬Habib‭ & ‬F.‭ ‬Therrien‭ ‬-‭ ‬2019.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Pterosauria,‭ ‬Pterodactyloidea,‭ ‬Azdharchidae.
Species: C.‭ ‬boreas‭ (‬type‭)‬.
Diet: Uncertain.
Size: Uncertain due to lack of remains,‭ ‬but largest fossils suggest an upper wingspan approaching‭ ‬10‭ ‬meters across.
Known locations: Canada‭ ‬-‭ ‬Dinosaur park Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Partial post cranial remains of several individuals including juveniles and adults.

       Among the pterosaurs Quetzalcoatlus is usually treated as one of if not the largest known pterosaur,‭ ‬and so for a long time any large pterosaur bones of the azdharchid line‭ (‬which Quetzalcoatlus belongs to‭)‬,‭ ‬were usually attributed to the genus.‭ ‬These included the growing numbers of large azdharchid pterosaur bones that were being found within the Dinosaur Park Formation of Canada.‭ ‬However,‭ ‬as more of these bones were found and looked at more closely it was realised that while they belong to a large azdharchid pterosaur,‭ ‬they actually represented a whole new genus.‭ ‬In‭ ‬2019‭ ‬these fossils were used to establish the pterosaur genus Cryodrakon.
       As mentioned,‭ ‬Cryodrakon was a large pterosaur of the azdharchid line.‭ ‬In fact Cryodrakon seems to have been one of the largest pterosaurs so far known,‭ ‬with larger fossils of Cryodrakon suggesting that larger adults could have had wingspans approaching ten meters across.‭ ‬This would make Cryodrakon only a‭ ‬little bit smaller than Quetzalcoatlus,‭ ‬and larger than most other pterosaurs.
