Lonchognathosaurus was a flying reptile with a long, pointed snout and needle-like teeth. It soared over lakes and rivers in what is now China during the Early Cretaceous Period, about 137 to 100 million years ago. It was not a dinosaur, but a pterosaur, a close cousin of dinosaurs.1 2

Datu dibertigarria: pterosauroak dinosauroen gainetik hegan egiten zuten, baina haien lehengusuak ziren, ez dinosauroak.

Its skull was about 400 mm (15.75 inches) long, and the tip of its upper jaw was needle-like.1

It had only eight teeth in each upper jaw, and they were spaced far apart, getting smaller towards the back.1 3

Unlike many other pterosaurs, the bottom edge of its upper jaw was straight, not curved.1

It had a crest on its head with grooves and a concave front edge.1

In 2022, a wing bone from Siberia was identified as possibly belonging to Lonchognathosaurus, suggesting it lived over a wider area than first thought.1

Some scientists think it might be the same as another pterosaur called Dsungaripterus, but others disagree.1 2

Lonchognathosaurus: AAk egindako irudia — Lonchognathosaurus nolakoa izan zitekeen erakusten duen AAk egindako irudia, ordenagailu batek zientzialariek dakitenetik sortua. Asmakizun bat da: benetako animalia desberdina izan zitekeen, eta inork ez daki zein ziren bere benetako koloreak.

Mito-hauslea

Mitoa: Lonchognathosaurus was a dinosaur.

Egia: It was a pterosaur, a flying reptile that is a close cousin of dinosaurs, but not a dinosaur itself.1
