Alcione

名字的意思： “from Alcyone, a woman in Greek myths who was turned into a seabird”1

吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Alcione was a flying reptile that lived near the end of the Age of Dinosaurs. It had short, strong wings and probably flew fast over the sea. It may have dived into the water like a kingfisher to catch fish.1

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。

酷東西

趣味知識

Alcione is the first nyctosaurid pterosaur ever found from the very end of the Cretaceous period in Africa.1

Its arm and hand bones were short and thick, which gave it a smaller wingspan than other nyctosaurids. This may have helped it fly fast or dive into water.1

The upper arm bone (humerus) of Alcione had a hatchet-shaped crest for muscle attachment, a clue that it was a nyctosaurid.1

Alcione lived about 72 to 66 million years ago, during the Maastrichtian stage. That is just before the big extinction that killed the non-bird dinosaurs.2

Scientists found Alcione in the same phosphate mines that have produced many other pterosaurs, like Phosphatodraco, and marine reptiles.1

Alcione was a small pterosaur compared to some of its giant relatives. Its short wings suggest it did not soar like a frigatebird but flapped more often.1

給恐龍專家

學名: Alcione
命名者: Longrich et al. 20185
類群: 飛行爬蟲類
科 / 演化支: Aponyctosauria5
分類: Pterosauria > Pterodactyloidea5
岩石的年代: 72 到 66 百萬年 (Maastrichtian)5
岩層: Couche III5

發現: Alcione was named in 2018 by Nicholas Longrich and colleagues. The first fossils were found in the Couche III layer at Sidi Daoui, Morocco, in a phosphate mine.2 1
仍有爭議: Scientists are not sure whether Alcione used its short wings for fast flapping flight or for plunge-diving into the sea after fish.1
