酷東西

趣味知識

Its full scientific name has 37 letters, making it the longest dinosaur name of all.2

It was only about 1 metre long, smaller than many modern dogs.2

It walked on two legs, like many other small herbivorous dinosaurs.2

The first fossil was found on a cliff near a train station called Hongtuyan.2

It lived alongside other dinosaurs like the armoured Pinacosaurus and the duck-billed Tanius.2

Scientists are not sure if it was a pachycephalosaur or a ceratopsian, because its skull roof was missing from the fossil.2
