名字的意思： “butterfly lizard”1

吃：植物長脖子恐龍侏羅紀晚期到白堊紀早期

Hudiesaurus was a gigantic, long-necked plant-eater that stomped through Late Jurassic China. It was one of the biggest dinosaurs ever, with a neck so long it could probably reach high into the treetops. Its name comes from the butterfly-like split on its backbone spines.1

趣味知識

Hudiesaurus might have been as long as three school buses parked end to end, reaching up to 32 metres (105 feet).1

Its backbone had a split spine at the top, which helped strong neck muscles attach. This gave it extra control over its long neck.1

The only definite fossil is a single backbone, but it was huge, measuring 55 centimetres (22 inches) long.1

Hudiesaurus lived about 154 to 143 million years ago, during the Late Jurassic period.1

Some bones that were once thought to be Hudiesaurus are now given to another dinosaur called Rhomaleopakhus.1

It had air-filled cavities in its backbone, which made its huge bones lighter, like a bird's bones.1
