酷東西

趣味知識

Dyoplosaurus means 'double-armoured lizard' because of its two layers of bony plates and spikes.1

Its tail club was smaller than those of other ankylosaurids, so scientists think it might not have been strong enough to break bones.1

Fossilized skin impressions show that Dyoplosaurus had a mosaic of small, bony bumps on its body.1

Dyoplosaurus lived alongside other dinosaurs like the horned Chasmosaurus, the duck-billed Corythosaurus, and the predator Gorgosaurus.1

The first Dyoplosaurus fossil was found in 1919 by Levi Sternberg near the Red Deer River in Alberta, Canada.1

For a long time, scientists thought Dyoplosaurus was the same as Euoplocephalus, but newer studies show it is its own unique dinosaur.1

關於 Dyoplosaurus 最常被問的問題

?How big was Dyoplosaurus?

Dyoplosaurus was about 4 to 4.5 metres long and weighed around 1.2 metric tons.1

?What did Dyoplosaurus eat?

Dyoplosaurus was a plant-eater. It had a beak-like mouth for cropping vegetation.2

?Could Dyoplosaurus break bones with its tail club?

Probably not. Its tail club was smaller than those of other ankylosaurids, and a 2009 study found it could not generate enough force to puncture bone.1

?When did Dyoplosaurus live?

Dyoplosaurus lived during the Late Cretaceous period, about 76.5 to 75 million years ago.1

迷思破解王

迷思： Some people think Dyoplosaurus was just a young Euoplocephalus.

真相： Scientists now agree that Dyoplosaurus is a separate genus with distinct features, like its triangular toe claws and tail club that is longer than wide.1

發現: Dyoplosaurus was named by William Parks in 1924 based on a partial skeleton found in Alberta, Canada. The name means 'double-armoured lizard'.1
仍有爭議: Scientists still debate exactly how Dyoplosaurus used its tail club. Some think it was for defense, but the club might have been too small to be effective.1
