趣味知識

Psittacosaurus is the non-avian dinosaur genus with the most known species, up to 13 different ones.1

One fossil of Psittacosaurus was found with long, bristle-like filaments on its tail, similar to those of the dinosaur Tianyulong.1

Psittacosaurus had a brain that was fairly large for its size, suggesting it may have had complex behaviors and good senses of smell and sight.1

Unlike later horned dinosaurs like Triceratops, Psittacosaurus walked on two legs as an adult and did not have a frill or large horns.1

Psittacosaurus swallowed gastroliths (stomach stones) to help break down tough plant material, sometimes more than 50 stones in one animal.1

The first Psittacosaurus fossil was discovered in Mongolia in 1922 by a chauffeur named Wong during an expedition led by Henry Fairfield Osborn.1

Psittacosaurus could slide its lower jaw forward and backward, which may have helped it crack nuts or seeds.1

關於 Psittacosaurus 最常被問的問題

?How big was Psittacosaurus?

About 2 metres (6.5 feet) long and weighed around 50 kilograms (110 pounds). That is about as long as a large bicycle.3 4

?What did Psittacosaurus eat?

It was a herbivore that ate tough plants. It used its strong beak to snip leaves and swallowed gastroliths (stomach stones) to help grind the food.1 3

?Did Psittacosaurus have feathers?

No, it did not have feathers. But one fossil shows long, bristle-like structures on its tail, which may have been modified scales, not feathers.1

?How fast could Psittacosaurus run?

Maybe up to about 35 km/h (22 mph), about as fast as a fast human runner. This is an estimate from its size. It was small and agile and ran on two legs as an adult.1 3

?When did Psittacosaurus live?

It lived during the Early Cretaceous Period, about 125 to 100 million years ago.1 3

?Where was Psittacosaurus found?

Fossils have been found in China, Mongolia, Russia, and Thailand.1 3

?Why is it called Psittacosaurus?

Its name means 'parrot lizard' in Greek, because its short, deep skull and strong beak look a lot like a parrot's beak.1 4

迷思破解王

迷思： Some people think Psittacosaurus was a type of parrot dinosaur that could fly.

真相： Psittacosaurus was a dinosaur that walked on two legs and could not fly. Its name means 'parrot lizard' because of its beak, not because it had wings.1
