酷東西

趣味知識

Jinchuanloong's skull is one of the most complete ever found for an early sauropod dinosaur.1 2

Its name 'niedu' comes from the Mandarin words for 'nickel' and 'city', because Jinchuan is famous for its nickel mines.1 2

The fossil includes the first five neck bones still attached to the skull, and 29 tail bones that were still in a row.1 2

Scientists think the holotype was not fully grown because some of its skull bones were not fused together.1

Jinchuanloong lived during the Middle Jurassic, about 168 to 165 million years ago, in what is now northwestern China.3 2

It belongs to a group called eusauropods, which includes many of the largest land animals that ever lived.1 2
