吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Dawndraco was a flying reptile with a very long, straight beak that did not taper like other pteranodonts. It soared over the ancient sea that covered Kansas about 86 million years ago, scooping up fish.1 2

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

趣味知識

Dawndraco is known from only one partial skeleton, including an almost complete skull and lower jaws.1 2

Its snout did not taper like in other pteranodonts; the upper and lower edges ran almost parallel.1 2

The species name kanzai honors the Kanza (Kaw) tribe, after which Kansas is named.1 2

Dawndraco lived about 86 million years ago, during the Late Cretaceous period.1 2

The fossil was found in the Smoky Hill Chalk Member of the Niobrara Formation, which was once the floor of a shallow sea.1 2

關於 Dawndraco 最常被問的問題

?Is Dawndraco a dinosaur?

No, Dawndraco is a pterosaur, a flying reptile that is not a dinosaur.1

?How big was Dawndraco?

The exact size is not known from the sources, but it was a pteranodontid pterosaur with a wingspan likely similar to other pteranodonts, around 4 to 6 metres (13 to 20 feet).1

?What did Dawndraco eat?

Dawndraco ate fish, which it scooped up while soaring over the ancient sea.1

?Why is Dawndraco controversial?

Some scientists think Dawndraco is not a separate genus but just a young male Pteranodon sternbergi, so its status is debated.1

迷思破解王

迷思： Dawndraco is definitely a separate genus from Pteranodon.

真相： Many scientists think Dawndraco is actually a young male of Pteranodon sternbergi (also called Geosternbergia), not a distinct genus.1
