Cetiosaurus

Izenaren esanahia: “whale lizard”1

Jaten zuen: LandareakLepo-luzeakErdi Jurasikoa eta Behe Kretazeoa artean

Cetiosaurus was one of the very first long-necked dinosaurs ever discovered. It lived in what is now England and France about 170 million years ago. This giant plant-eater was as long as a bus and weighed as much as two elephants!1 2

Datu dibertigarriak

Cetiosaurus was named in 1841 by Sir Richard Owen, the same scientist who later invented the word 'dinosaur'. Owen thought it was a giant sea crocodile, not a land dinosaur.1

Its name means 'whale lizard' because Owen believed it was a marine reptile. We now know it was a long-necked dinosaur that walked on land.1

Cetiosaurus had a shorter neck and tail than many other sauropods, but its front legs were as long as its back legs.1

The first Cetiosaurus fossils were found near Chipping Norton, Oxfordshire, England, in the early 1800s.1

A nearly complete skeleton called the 'Rutland Dinosaur' was discovered in 1968 in a clay pit in Rutland, England. It took two years to identify it as Cetiosaurus.1

Cetiosaurus was about 16 to 18 metres long (52 to 59 feet) and weighed around 11 tonnes (12 short tons). That's as heavy as two African elephants!1 2

Cetiosaurus: gehien egindako galderak

?How big was Cetiosaurus?

Cetiosaurus was about 16 metres (52 feet) long and weighed roughly 11 tonnes (12 short tons). That is as long as two double-decker buses and as heavy as two African elephants.1 4

?What did Cetiosaurus eat?

Cetiosaurus was a herbivore, meaning it ate plants. It had peg-like teeth for stripping leaves and branches.1 5

?When did Cetiosaurus live?

Cetiosaurus lived during the Middle Jurassic Period, about 171 to 165 million years ago.1

?Where was Cetiosaurus found?

Fossils of Cetiosaurus have been found mainly in England, but also in France, Switzerland and Morocco. The first fossils were discovered near Chipping Norton, Oxfordshire, England.1

?Is Cetiosaurus a dinosaur?

Yes, Cetiosaurus is a dinosaur. It is a sauropod dinosaur, a group of long-necked, plant-eating giants. When first discovered, scientists thought it was a marine reptile, but we now know it was a land dinosaur.1 5

?Why is it called Cetiosaurus?

Its name means 'whale lizard' because the scientist who named it, Sir Richard Owen, thought it was a giant sea reptile. We now know it was a land dinosaur.1

Mito-hauslea

Mitoa: Many people think Cetiosaurus was a whale or a sea monster because of its name.

Egia: Cetiosaurus was a land-dwelling dinosaur, not a whale or marine reptile. Its name was given before scientists knew it was a dinosaur.1
