Cryodrakon

名字的意思： “cold dragon”5

吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Cryodrakon was a huge flying reptile that soared over Canada about 76 million years ago. It was not a dinosaur, but a pterosaur with a wingspan as wide as a small airplane. This cold dragon ruled the skies and snatched fish from ancient rivers.5 1

趣味知識

Cryodrakon was first described in 2019, making it a very recently discovered pterosaur.5

It lived during the Campanian age of the Late Cretaceous, between 83.6 and 72.2 million years ago.1

The type specimen of Cryodrakon is a set of postcranial bones, meaning skull and jaws are not yet known.5

Cryodrakon belonged to a group called Azhdarchidae, which includes some of the largest flying animals ever.1

Its fossils come from two locations in Alberta, Canada, both from the same rock formation.5

?Where was Cryodrakon found?

Cryodrakon fossils were discovered in Alberta, Canada, in the Dinosaur Park Formation. The first bones were found in 1972, and the most complete skeleton was uncovered in 1992.2 4

?Is Cryodrakon a dinosaur?

No, Cryodrakon is not a dinosaur. It is a pterosaur, a type of flying reptile that lived at the same time as dinosaurs.2 4
