Thescelosaurus

名字的意思： “marvellous lizard”1

吃：植物有喙的草食恐龍白堊紀晚期

Thescelosaurus was a small, plant-eating dinosaur that lived near the end of the age of dinosaurs. It walked on two legs, had a long tail that helped it balance, and a toothless beak at the front of its snout. It was one of the last non-bird dinosaurs before they all went extinct 66 million years ago.1

酷東西

趣味知識

Thescelosaurus had more teeth than its relatives, and the teeth were different shapes for different jobs.1

Its tail made up half its body length and was stiffened by rod-like tendons.1

Scientists think Thescelosaurus might have dug burrows, because it had a good sense of smell but poor hearing, like modern burrowing animals.1

A fossil of Thescelosaurus was thought to have a preserved heart in 2000, but later scientists doubted that idea.1

Its brain was small, which might mean it lived in groups of only two or three animals.1

Thescelosaurus had five fingers on its hand and four toes on its foot.1

It was probably not a fast runner, because its thigh bone was longer than its shin bone.1

你們都在問

關於 Thescelosaurus 最常被問的問題

?How big was Thescelosaurus?

About 3 to 4 metres (10 to 13 feet) long and weighed 200 to 300 kilograms (440 to 660 pounds).1

?What did Thescelosaurus eat?

It was a plant-eater, or herbivore, that likely picked leaves and other plants with its toothless beak and many teeth.1

?Did Thescelosaurus have feathers?

No one knows for sure. No feather impressions have been found on any Thescelosaurus fossil, but some other ornithischian dinosaurs had simple feathers.1

?Could Thescelosaurus swim?

Probably not. Its body was built for walking on land, with a long tail for balance and strong legs, not for swimming.1

?Was Thescelosaurus bigger than T. rex?

No, it was much smaller. Thescelosaurus was about 3 to 4 metres long, while T. rex could be over 12 metres long.1

?When did Thescelosaurus go extinct?

It died out about 66 million years ago, along with all other non-bird dinosaurs, in the Cretaceous-Paleogene extinction event.1

迷思破解王

迷思： Some people thought Thescelosaurus had a fossilized heart.

真相： Scientists now doubt that the object found inside a specimen was a heart.1
