Euoplocephalus

名字的意思： “well-armoured head”1

吃：植物甲龍類白堊紀晚期

Euoplocephalus was a tank-like dinosaur covered in bony armour and a heavy club on its tail. It lived in what is now Canada and the USA during the Late Cretaceous period. This slow-moving plant-eater could defend itself from big predators like Albertosaurus.1

趣味知識

Euoplocephalus had a heavy club at the end of its tail made of bone. It could swing this club to fight off predators.1

Its body was covered in rows of bony plates called scutes. It also had two bone rings around its neck for extra protection.1

Euoplocephalus was about 5.3 metres (17 feet) long and weighed around 2 metric tons (2.2 short tons). That is as heavy as a small car.1

The first fossil was found in 1897 in Alberta, Canada. It was originally named Stereocephalus, but that name was already used for an insect, so it was changed to Euoplocephalus in 1910.1

Euoplocephalus lived between about 76 and 75 million years ago, during the late Campanian stage of the Late Cretaceous.1

Scientists once thought many different ankylosaur fossils all belonged to Euoplocephalus, but now they know most are separate species like Scolosaurus and Platypelta.1

Euoplocephalus had a short, drooping snout and a horny beak to bite off plants. Its teeth show it could chew tough plant material.1

關於 Euoplocephalus 最常被問的問題

?How big was Euoplocephalus?

About 5.3 metres (17 feet) long and 2 tonnes (2.2 short tons) in weight, as heavy as a small car.1 3

?What did Euoplocephalus eat?

It was a plant-eater. It used a horny beak to bite off plants and had small teeth to chew tough plant material.1 3

?Did Euoplocephalus have a tail club?

Yes, it had a heavy bony club at the end of its tail. It could swing this club to defend itself from predators like Albertosaurus.1 3

?Was Euoplocephalus bigger than Ankylosaurus?

No, Ankylosaurus was bigger. Among ankylosaurids, Euoplocephalus was exceeded in size only by Ankylosaurus and perhaps Tarchia and Cedarpelta.1

?When did Euoplocephalus live?

It lived during the Late Cretaceous period, about 76 to 70 million years ago.3

?Where was Euoplocephalus found?

Fossils have been found in Canada (Alberta) and the United States (Montana).1 3

?How fast could Euoplocephalus run?

Nobody knows for sure, but it was a slow-moving dinosaur with short, sturdy legs built for walking, not running.1

?What does the name Euoplocephalus mean?

It means 'well-armed head', from Greek words for 'well', 'armed', and 'head'.1

迷思破解王

迷思： Euoplocephalus could roll into a ball like an armadillo to protect itself.

真相： Euoplocephalus could not roll into a ball. It relied on its armour and tail club for defence.1

發現: Canadian paleontologist Lawrence Morris Lambe discovered the first Euoplocephalus fossil on 18 August 1897 in what is now Dinosaur Provincial Park, Alberta. He named it Stereocephalus in 1902, but changed the name to Euoplocephalus in 1910 because the old name was already taken.1
仍有爭議: Scientists still debate exactly which fossils belong to Euoplocephalus and which belong to other closely related ankylosaurs like Anodontosaurus and Scolosaurus.1
