Jianchangnathus

Naam beteken: “jaw from Jianchang County”1

Het geëet: VisVlieënde reptieleMiddel-Jura tot Laat JuraTegnies nie 'n dinosourus nie

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

Prettige feit: pterosourusse het oor die dinosourusse gevlieg, maar hulle was hul neefs, nie self dinosourusse nie.

Prettige feite

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

KI-prent van Jianchangnathus — 'n KI-prent van hoe Jianchangnathus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Mite-breker

Mite: Some people think pterosaurs like Jianchangnathus were dinosaurs.

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

Vir dino-kenners

Wetenskaplike naam: Jianchangnathus

Steeds omstrede: Scientists are not sure about the exact age of the rocks where Jianchangnathus was found. They might be from the Middle Jurassic or the Early Cretaceous.2
