名字的意思： “small seizer”1

吃：肉迅猛龍類白堊紀早期

Microraptor was a tiny dinosaur with four wings! It had long feathers on its arms and legs, so it could glide or even fly from tree to tree. This little hunter lived in the forests of ancient China.1

酷東西

趣味知識

Microraptor had four wings: one pair on its arms and another on its legs. This helped it glide between trees like a flying squirrel.1

It lived about 125 to 120 million years ago, during the Early Cretaceous period.1

One fossil of Microraptor had a mammal foot in its stomach. This shows that it sometimes ate small mammals.1

Microraptor was smaller than the earliest bird, Archaeopteryx. It is one of the smallest non-avian dinosaurs ever found.2

Scientists found fish scales inside another Microraptor fossil. This means it could catch fish, maybe by swooping down to the water.1

The first fossil of Microraptor was part of a fake dinosaur made from pieces of different animals. Scientists discovered the trick and named the real dinosaur Microraptor.1

關於 Microraptor 最常被問的問題

?How big was Microraptor?

Microraptor was tiny, about the size of a pigeon. One species measured about 77 centimetres (2.5 feet) long and weighed about 0.5 to 1.4 kilograms (1.1 to 3.1 pounds).1

?Could Microraptor fly?

Yes, scientists think Microraptor could glide and maybe even fly using all four wings. It had long feathers on its arms and legs that helped it move through the air.1 3

?What did Microraptor eat?

Microraptor was a hunter that ate small animals. Fossils show it ate mammals, birds, lizards, and even fish, so it was an opportunistic feeder.1

?When did Microraptor live?

Microraptor lived about 125 to 120 million years ago, during the Early Cretaceous period.1

?Where was Microraptor found?

Microraptor fossils were found in Liaoning, China, in rocks from the Jiufotang Formation.1

?Was Microraptor a dinosaur?

Yes, Microraptor was a small, four-winged dromaeosaurid dinosaur, not a bird, even though it had feathers and could fly or glide.1

?Did Microraptor have feathers?

Yes, Microraptor had long feathers on its arms, legs, and tail. Some fossils even show it had glossy black iridescent feathers.1

?Why did Microraptor have four wings?

Microraptor had four wings to help it glide and fly between trees. The extra wings on its legs gave it more lift and control in the air.1 3

迷思破解王

迷思： Some people think Microraptor was a bird because it had four wings and feathers.

真相： Microraptor was a dinosaur, not a bird. It belongs to a group of meat-eating dinosaurs called dromaeosaurids, which are close relatives of birds.1
