Yangchuanosaurus was a huge meat-eating dinosaur that lived in China during the Jurassic period. It was one of the top predators of its time, with sharp teeth and strong legs for chasing prey.1

izinto ezimnandi

Iinyani ezimnandi

Yangchuanosaurus had six large holes in its skull that helped make the skull lighter, so it could move its head more easily.1

Its eyes faced forward, which gave it good depth perception to judge distances when hunting.1

It had a long tail that helped it balance its body when running.1

The first skeleton was found by workers digging foundations for the Shangyou Reservoir Dam in 1977.2 1

In 1981, fossils of Yangchuanosaurus shangyouensis were nearly lost in a flood when the Chongqing Museum of Natural History laboratory was partially submerged, but the fossils were saved.1

Yangchuanosaurus lived about 168 to 157 million years ago, during the Jurassic period.1

Umfanekiso owenziwe yi-AI: Yangchuanosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Yangchuanosaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Yangchuanosaurus

?How big was Yangchuanosaurus?

About 8 to 11 metres long and weighed up to 3.4 metric tons.4 1 5 6

?Was Yangchuanosaurus bigger than T. rex?

No, Yangchuanosaurus was smaller and lighter than T. rex, with longer arms.1

?What did Yangchuanosaurus eat?

It was a meat-eater that likely hunted large dinosaurs like Mamenchisaurus and may have also scavenged.1 6

?When did Yangchuanosaurus live?

It lived during the Jurassic period, about 168 to 145 million years ago.1 5 6

?Who discovered Yangchuanosaurus?

It was named by Chinese palaeontologist Dong Zhiming in 1978, discovered during construction of the Shangyou Reservoir Dam in 1977.4 6

?Why did Yangchuanosaurus have a long tail?

Its long tail helped balance its body when it ran after prey.1 6

Inyaniso ngeentsomi

Intsomi: Some people think Yangchuanosaurus was a type of tyrannosaur.

Inyaniso: Yangchuanosaurus was actually an allosaur, not a tyrannosaur. It belonged to a different group of large meat-eating dinosaurs.1
