趣味知識

Struthiomimus looked a bit like a featherless ostrich with a long tail.1

Its neck made up about 40% of the length of its body in front of the hips.2

It had three fingers on each hand that were roughly the same length, which is unusual for a theropod.2

Its tail was relatively stiff and probably helped it keep balance while running.2

Some scientists think its hands worked like a hook or clamp to pull branches close, but others think they supported wing feathers.2

Struthiomimus lived about 77 to 66 million years ago, during the Late Cretaceous.2 3

關於 Struthiomimus 最常被問的問題

?How big was Struthiomimus?

About 4.3 metres (14 feet) long, 1.4 metres (4.5 feet) tall at the hips, and weighed around 150 kilograms (330 pounds). A larger specimen weighed about 234 kilograms (515 pounds).2 1

?How fast could Struthiomimus run?

It could run between 50 and 80 km/h (31 to 50 mph), using its long legs to escape predators like tyrannosaurs.2

?What did Struthiomimus eat?

It was probably an omnivore, eating both plants and small animals like insects, mammals, and reptiles. Its toothless beak was good for cropping plants and maybe filtering food from water.2 1

?Did Struthiomimus have feathers?

Yes, it likely had feathers all over its body. Its arm bones show adaptations that may have supported wing feathers.2

?Where did Struthiomimus live?

It lived in western North America, in what is now Canada and the United States, during the Late Cretaceous period.2 1

?Why is it called Struthiomimus?

Its name means 'ostrich mimic' because it looked a lot like a modern ostrich, with long legs, a long neck, and a toothless beak.2 1

?Was Struthiomimus bigger than a human?

Yes, it was about 4.3 metres long and stood about 1.4 metres tall at the hips, which is taller than most people.2

?Did Struthiomimus have teeth?

No, it had a horny beak and no teeth. It used its beak to eat plants and small animals.2 1

迷思破解王

迷思： Struthiomimus was a fierce meat-eater like other theropods.

真相： It had no teeth and a beak, and most scientists think it ate both plants and small animals, not just meat.2
