吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Mistralazhdarcho was a huge flying reptile that soared over ancient France. It was not a dinosaur, but a pterosaur, a cousin of dinosaurs that ruled the skies. With a wingspan as wide as a small car, it was one of the biggest animals in the air.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。

酷東西

趣味知識

Mistralazhdarcho had a bump on the top of its lower jaw, which might have helped it crush shellfish or make sounds.1

Its bones were found scattered over a small area, so scientists think they all came from one young animal.1

It was a medium-sized azhdarchid, bigger than some relatives but smaller than the giant Hatzegopteryx.2

The first fossil was found in 1992, but it took until 2018 for scientists to name it.1

Its closest relative might be Aerotitan from Argentina, even though they lived far apart.1

關於 Mistralazhdarcho 最常被問的問題

?How big was Mistralazhdarcho?

Its wingspan was about 4.5 metres (15 feet) for the young fossil found, and adults may have reached 5 to 6 metres (16 to 20 feet). That is as wide as a small car.1 2

?Was Mistralazhdarcho a dinosaur?

No, it was a pterosaur, a flying reptile that lived alongside dinosaurs but is not one itself.1

?What did Mistralazhdarcho eat?

Scientists are not sure, but the bump on its lower jaw might have helped it crush shellfish. It likely ate small animals or fish.1

?When did Mistralazhdarcho live?

It lived during the Late Cretaceous period, about 72 million years ago, in what is now France.1
