吃：植物奇特的羽毛恐龍白堊紀早期

Suzhousaurus was a huge, plant-eating dinosaur with a big belly, strong legs, and long claws. It lived in China during the Early Cretaceous, about 124 to 113 million years ago. It probably had feathers, just like its close relatives!1

趣味知識

Suzhousaurus was one of the largest Early Cretaceous therizinosauroids, reaching about 6 metres (20 feet) long and weighing around 3.1 tonnes (3,100 kilograms).1

Its upper arm bone (humerus) had very expanded ends and a big entepicondyle, which helped scientists identify it as a therizinosauroid.3

Unlike more advanced therizinosaurids, Suzhousaurus's backbone was not highly pneumatized, meaning it had fewer air spaces in its vertebrae.1

Its pelvis was opisthopubic, a feature that is typical of therizinosaurids, even though Suzhousaurus was a more basal member of the group.1

Suzhousaurus had a large belly and a reduced tail, which helped it balance its heavy body.1

Feather impressions from the related Beipiaosaurus suggest that Suzhousaurus was probably at least partially feathered.1

The first specimen, FRDC-GSJB-99, was found in 1999 and includes a right humerus, shoulder bones, ten back vertebrae, and part of the pelvis, but no skull.1

A second, more complete skeleton found in 2004 includes the sacrum, tail vertebrae, a nearly complete pelvis, and both thigh bones.1

關於 Suzhousaurus 最常被問的問題

?How big was Suzhousaurus?

Suzhousaurus was about 6 metres (20 feet) long and weighed around 3.1 tonnes (3,100 kilograms). That makes it one of the largest Early Cretaceous therizinosauroids.1

?What did Suzhousaurus eat?

It was a plant-eater. It had a big belly, strong legs, and long claws for browsing on plants.1

?Did Suzhousaurus have feathers?

Probably yes. Feather impressions from its close relative Beipiaosaurus suggest that Suzhousaurus was at least partially feathered.1

?When did Suzhousaurus live?

It lived during the Early Cretaceous, about 124 to 113 million years ago, in what is now China.1

?Was Suzhousaurus a dinosaur?

Yes, it was a theropod dinosaur, specifically a therizinosauroid.1

?Why did Suzhousaurus have long claws?

Its long claws were probably used for pulling down branches and leaves to eat, like other therizinosauroids.1

迷思破解王

迷思： Suzhousaurus was a fierce meat-eater because it had big claws.

真相： Actually, Suzhousaurus was a herbivore. Its claws were probably used for pulling down branches or digging, not for hunting.1 2

發現: The first Suzhousaurus fossil was found in 1999 in the Yujingzi Basin, China. Scientists named it Suzhousaurus megatherioides in 2007, and the name means 'Suzhou lizard' after the old name for the Jiuquan area.1
仍有爭議: Scientists are not sure if Suzhousaurus is the same animal as another therizinosauroid called 'Nanshiungosaurus' bohlini, because the fossils do not overlap and the original specimen is lost.1
