吃：植物長脖子恐龍侏羅紀中期到白堊紀早期

Xinjiangtitan was a gigantic, long-necked plant-eater that lived in what is now China. Its neck was the longest complete neck ever found on any animal, stretching almost 15 metres (49 feet). It was one of the longest dinosaurs ever discovered, as long as a blue whale!1

酷東西

趣味知識

Xinjiangtitan's neck had 18 vertebrae and was nearly 15 metres (49 feet) long, the longest complete neck of any known animal.1

Its thigh bone (femur) was 1.65 metres (5.4 feet) long, taller than most adult humans.1

The backbone of Xinjiangtitan is one of the most complete vertebral columns ever found for a sauropod in Asia.1

Xinjiangtitan lived during the Middle Jurassic period, about 164 million years ago.1

Scientists think Xinjiangtitan weighed up to 40 metric tons (44 short tons), as much as a herd of elephants.1

Xinjiangtitan had some features similar to diplodocid dinosaurs, like a short hind limb and a special bump on its pubis bone.1
