名字的意思： “Dorset giant”1

吃：植物長脖子恐龍侏羅紀晚期到白堊紀早期

Duriatitan was a huge, long-necked plant-eater that stomped through what is now England about 150 million years ago. It is known from just one big arm bone, but that bone tells us it was a giant!1

酷東西

趣味知識

Duriatitan is only known from a single left upper arm bone, called a humerus.1

The bone was found near Sandsfoot, Weymouth in Dorset, England, by a man named R.I. Smith.1

It was first named in 1874 as a species of Cetiosaurus, and later given its own genus in 2010.1

The name Duriatitan comes from the Latin name for Dorset, Duria, and the Greek word Titan, meaning giant.1

Scientists think Duriatitan lived during the Late Jurassic, about 150 million years ago.1

It was a titanosauriform, a group of sauropods that includes some of the largest land animals ever.4

Thomas Holtz estimated Duriatitan could have been up to 25 meters (82 feet) long, as long as a blue whale.1

關於 Duriatitan 最常被問的問題

?How big was Duriatitan?

Duriatitan may have been up to 25 meters long, which is shorter than a 30 meter blue whale, though this is an estimate from one bone.1 3

?What did Duriatitan eat?

Duriatitan was a plant-eater, eating tough leaves from trees. Its huge body and long neck helped it reach food other dinosaurs couldn't.3

?Could Duriatitan swim?

Scientists once thought sauropods like Duriatitan lived in water, but now they think the opposite. Its air-filled bones and small feet would have made it float and be unstable in water.3

?When did Duriatitan live?

Duriatitan lived during the Late Jurassic, about 150 million years ago, in what is now England.1 4

發現: The first fossil, a partial left upper arm bone, was found by R.I. Smith near Sandsfoot, Weymouth in Dorset. It was described by John Hulke in 1874 as a species of Cetiosaurus, and later renamed Duriatitan by Paul Barrett, Roger Benson, and Paul Upchurch in 2010.1
仍有爭議: Scientists are not sure exactly how big Duriatitan was, because only one arm bone has been found. The length estimate of 25 meters is just a guess.1
