酷東西

趣味知識

Sinoceratops had a short, hooked horn on its nose and no horns above its eyes, which is different from many other horned dinosaurs.1

Its neck frill had a row of forward-curving hornlets that made it look like a crown, plus a series of low knobs on top that no other horned dinosaur has.1

The skull of Sinoceratops was about 180 cm (5.9 ft) long, making it one of the largest centrosaurine skulls known.2

It was much larger than most other centrosaurines, similar in size to some chasmosaurines.2

Sinoceratops lived alongside the giant duck-billed dinosaur Shantungosaurus and the tyrannosaur Zhuchengtyrannus.1

It is the only ceratopsid dinosaur known from Asia; all other ceratopsids are from North America.1
