Fun facts
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

Most asked questions about Mistralazhdarcho
?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.12
?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
