Mistralazhdarcho

Say it: MISS-tral-azh-DAR-ko
Name means: “Mistral wind and Azhdarcho, a related pterosaur”1
Ate: FishFlying reptilesLate CretaceousNot technically a dinosaur

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.12

Fun fact: pterosaurs flew over the dinosaurs, but they were their cousins, not dinosaurs themselves.

Fun facts

1

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

2

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

3

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

4

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

5

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

?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?
