吃：肉肉食恐龍侏羅紀晚期

Sciurumimus was a small meat-eating dinosaur that lived in what is now Germany. It looked a bit like a tiny squirrel because it had a long, fluffy tail. Even though it was a young dinosaur, it was already a fast hunter.1

酷東西

趣味知識

Sciurumimus is known from just one beautifully preserved baby skeleton.1

Its tail had long, fuzzy filaments that looked like a squirrel's tail, which is how it got its name.1

The fossil even shows some muscle tissue along the back of its leg.1

Sciurumimus had big eyes and a large head compared to its body, like a baby animal.1

Scientists are not sure where Sciurumimus belongs on the dinosaur family tree. Some say it is a megalosauroid, others think it is a coelurosaur.1

你們都在問

關於 Sciurumimus 最常被問的問題

?How big was Sciurumimus?

The only known fossil is a baby about 70 cm (2.3 ft) long. Adults probably reached 6 metres (19.7 ft) or more.2

?Did Sciurumimus have feathers?

Yes. The fossil shows long, hair-like filaments on the tail and body that are identical to stage 1 feathers found in other dinosaurs.1 3

?What did Sciurumimus eat?

The baby probably ate insects and other small prey, based on its slender, pointed teeth. Adults likely hunted larger dinosaurs.2

?Is Sciurumimus a dinosaur?

Yes, it is a theropod dinosaur, a meat-eater that lived about 150 million years ago in what is now Germany.1

?Why is it called Sciurumimus?

Its name means 'squirrel mimic' because its fluffy tail looks like a tree squirrel's tail.1

?How fast could Sciurumimus run?

Scientists do not know its exact speed, but as a small, fast hunter it was probably quick on its feet.1

迷思破解王

迷思： Because it had feathery filaments, Sciurumimus was a bird-like dinosaur.

真相： Sciurumimus was a meat-eating theropod dinosaur, not a bird, and its filaments were simple stage 1 feathers similar to those found in some ornithischian dinosaurs and early tyrannosaurs.1

發現: The first and only Sciurumimus fossil was found in a limestone quarry near Painten, Germany, and named by scientists Rauhut, Foth, Tischlinger, and Norell in 2012.1 4
仍有爭議: Scientists still debate whether Sciurumimus is a basal megalosauroid or a coelurosaur, because its only known skeleton is from a very young animal, making its adult features hard to guess.1
