Utuntu dushimishije

1

Zhanghenglong had five holes in its upper jaw, four small ones in a row and one big one near the cheek bone. This is a mix of features seen in older and newer duck-billed dinosaurs.2

2

Its teeth had two ridges, one in the middle and one off to the side. This is a transitional feature between early and later hadrosauroids.2

3

The lower jaw had 26 tooth positions, and each position could have up to four teeth stacked up. That means it had a lot of spare teeth for chewing.2

4

Zhanghenglong is named after Zhang Heng, a famous Chinese astronomer and inventor from about 1,800 years ago. The name also includes 'long', which means dragon in Chinese.1

5

The fossils were found near a village called Zhoujiagou, not far from a dinosaur relics park in Xixia County.2

6

Scientists think Zhanghenglong was a close relative of the true duck-billed dinosaurs, and it may help show that duck-billed dinosaurs came from Asia.2

Byakozwe na AIIshusho ya Zhanghenglong yakozwe na AI
Ishusho yakozwe na AI yerekana uko Zhanghenglong 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.
