Azhdarchid pterosaurs have been known since 1972 from upper Campanian
deposits of Alberta, Canada. Originally represented by only very
fragmentary remains tentatively assigned to the genus Quetzalcoatlus,
additional material uncovered over the years has revealed that the
taxonomic identity of the Alberta pterosaur material is at odds with this
in the light of the growing understanding of azhdarchid diversity. Here, we
describe previously undocumented pterosaur remains from Alberta and
reassess previously studied material. The specimens collected from the
Dinosaur Park Formation can be assigned to a new genus and species
Cryodrakon boreas, gen. et sp. nov. The largest elements referable to this
taxon suggest that this genus reached sizes comparable to those of other
giant azhdarchids.
