Question 1

How do you say Jingshanosaurus?

Accepted Answer

Jingshanosaurus is pronounced jing-SHAHN-oh-sore-us. Break it into four chunks: JING, then SHAHN, then OH, then SORE-US. The stress lands on the SHAHN part in the middle. A good memory trick is to think of it as 'jing-SHAHN, oh, a saurus,' like you are surprised to meet a lizard named after a Chinese place.

Question 2

What does Jingshanosaurus mean?

Accepted Answer

Jingshanosaurus means the Jingsha lizard, with Jingsha referring to the locality in Yunnan Province, China, where the fossil was discovered. The ending saurus comes from the Ancient Greek word sauros, meaning lizard, and it appears in hundreds of dinosaur names. Scientists often name dinosaurs after the place they were found, so the name is essentially a permanent address label linking this animal to its Chinese home.

Question 3

How big was Jingshanosaurus?

Accepted Answer

Jingshanosaurus grew up to 5 metres long, which is about 16 feet, roughly the length of a large pickup truck. It weighed around 4.3 tonnes, which is close to the weight of a hippopotamus or a very heavy SUV. Its thigh bone alone measured 845 mm, about as long as a baseball bat, giving scientists a good sense of just how powerfully built this animal was for its time.

Question 4

What did Jingshanosaurus eat?

Accepted Answer

Jingshanosaurus was a herbivore, meaning it ate only plants. It used its leaf-shaped teeth to strip ferns, cycads, and early conifers that grew across the floodplains of Early Jurassic China. Its long neck would have helped it reach vegetation at different heights, and it likely needed to eat huge quantities of plant material every day to fuel a body weighing over 4 tonnes.

Question 5

When did Jingshanosaurus live?

Accepted Answer

Jingshanosaurus lived approximately 199.5 million years ago during the Early Jurassic period. That places it right at the very beginning of the Jurassic, just after the mass extinction event at the end of the Triassic period that wiped out many competing reptile groups and allowed dinosaurs to spread and grow. In geological terms, it was alive during a time called the Hettangian age.

Question 6

Where was Jingshanosaurus found?

Accepted Answer

Jingshanosaurus was found in Yunnan Province in southwestern China, specifically in the Lufeng Basin area near the Jingsha and Xinwa localities. The fossils came from the Lower Lufeng Formation, a sequence of reddish sedimentary rock that has been producing dinosaur bones since the 1930s. Yunnan is so rich in early dinosaur fossils that it is sometimes called the hometown of dinosaurs in China.

Question 7

Is Jingshanosaurus related to Brachiosaurus or other big dinosaurs?

Accepted Answer

Yes, Jingshanosaurus is related to the giant sauropods like Brachiosaurus, just much earlier in the family tree. It belongs to the broader group Sauropodomorpha, which includes all the long-necked plant-eaters from the small bipedal forms of the Triassic all the way up to the enormous titanosaurs of the Cretaceous. Jingshanosaurus represents an early experiment in getting very large, giving scientists a glimpse of the evolutionary steps that eventually led to the biggest animals to ever walk the Earth.

Question 8

Who discovered Jingshanosaurus?

Accepted Answer

Jingshanosaurus was formally described in 1995 by Chinese paleontologist Zhang Yunhui and colleagues. The species was named xinwaensis after the Xinwa locality in the Lufeng region of Yunnan Province where the material was collected. China has a long and rich history of dinosaur discovery in Yunnan, stretching back to the pioneering work of Yang Zhongjian, often called the father of Chinese vertebrate paleontology, who worked the Lufeng Basin from the 1930s onward.
