Jianchangnathus was a small flying reptile that soared over ancient China. It had a long tail and sharp teeth for catching fish. It was not a dinosaur, but a pterosaur, a cousin of dinosaurs.1 4

Akantu gashimishije: pterozore zagurukaga hejuru ya dinozore, ariko zari babyara bazo, si dinozore ubwazo.

Utuntu dushimishije

Jianchangnathus had a big front branch on its cheekbone, which is a unique feature.1

The first three pairs of teeth in its lower jaw pointed strongly forward, helping it snatch fish.1

Its lower jaw had a convex, or bulging, top edge, which is different from many other pterosaurs.1

Scientists think its body was covered in fuzzy pycnofibers, and some fossils suggest these were brown.1

Jianchangnathus lived about 160 million years ago, during the Middle Jurassic period.1

It is closely related to Scaphognathus, a pterosaur from Germany, but Jianchangnathus lived in China.1 2

Ishusho ya Jianchangnathus yakozwe na AI — Ishusho yakozwe na AI yerekana uko Jianchangnathus ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Gusenya ibinyoma

Ibivugwa: Some people think pterosaurs like Jianchangnathus were dinosaurs.

Ukuri: Pterosaurs were flying reptiles, not dinosaurs. They are a separate group of reptiles that lived at the same time as dinosaurs.1
