酷東西

趣味知識

Dacentrurus was one of the largest stegosaurs, about as long as a school bus.1

It was the first stegosaur dinosaur ever discovered, with good remains found in 1875.1 2

Dacentrurus had two rows of small plates on its neck and two rows of long spikes on its tail.1

Its name was changed from Omosaurus because that name was already used for a different ancient reptile.1

The gut of Dacentrurus was especially broad, suggesting it had a large belly for digesting plants.1

Fossils of Dacentrurus have been found in Portugal, Spain, France, and England.1 2

關於 Dacentrurus 最常被問的問題

?How big was Dacentrurus?

About 8 to 9 metres long and weighed up to 5 to 7.4 metric tons. That is about as long as a school bus.1 2

?What did Dacentrurus eat?

It was a plant-eater, or herbivore. It ate ferns, conifers (trees with cones), and cycads (palm-like trees).3

?Did Dacentrurus have spikes?

Yes, it had two rows of small plates on its neck and two rows of long spikes on its tail. The tail spikes could be used as a weapon.1 3

?When did Dacentrurus live?

It lived during the Late Jurassic and maybe Early Cretaceous periods, about 154 to 140 million years ago.1 2

?Where was Dacentrurus found?

Fossils have been found in England, France, Portugal, and Spain. The first skeleton was discovered in a clay pit in Swindon, England.1 2

?Was Dacentrurus bigger than Stegosaurus?

Dacentrurus was about the same size as Stegosaurus. Both are among the largest known stegosaurs.1

?How fast could Dacentrurus run?

Probably only about 12 km/h (7 mph), about as fast as a kid running fast. This is an estimate. Its front legs were much shorter than its back legs, which made running hard.3

發現: Dacentrurus was first named Omosaurus armatus by Richard Owen in 1875, based on a skeleton found in a clay pit in Swindon, England. In 1902, Frederick Augustus Lucas renamed it Dacentrurus because the name Omosaurus was already taken.1
仍有爭議: Scientists still debate whether the dinosaur Miragaia longicollum is actually the same species as Dacentrurus.1
