酷東西

趣味知識

Halszkaraptor had a very long neck for a dinosaur, about 20 cm (7.9 in) long, which is almost half its total body length.1

Its front limbs were short and flipper-like, which scientists think it may have used to paddle in water.1

The snout had many tiny holes that might have held sensors to detect vibrations in water, like a crocodile.1

The only known fossil was smuggled out of Mongolia and later returned after scientists proved it was real using a powerful X-ray scanner.1

It lived about 75 million years ago, during the Late Cretaceous period.1

Some scientists think Halszkaraptor was an insectivore that hunted small bugs in murky water or at night, because its eyes were large.1

關於 Halszkaraptor 最常被問的問題

?Was Halszkaraptor a dinosaur?

Yes, Halszkaraptor was a small, duck-sized dromaeosaurid dinosaur from the Late Cretaceous.1

?How big was Halszkaraptor?

About the size of a mallard duck. Its head was 7 cm long and its neck was 20 cm long.1

?Could Halszkaraptor swim?

Some scientists think it could swim using flipper-like forelimbs and a long neck, but others disagree because its bones were not dense enough.1 2

?What did Halszkaraptor eat?

It likely ate small fish or insects. Its sharp, backward-curving teeth and snout sensors helped it catch prey in water.1 3

?Why did Halszkaraptor have a long neck?

Its long, swan-like neck helped it strike at prey in the water, similar to how herons hunt today.1 3

?When did Halszkaraptor live?

It lived about 75 million years ago, during the Late Cretaceous period.1

迷思破解王

迷思： Halszkaraptor was a fully aquatic dinosaur like a dolphin.

真相： Scientists debate whether it was semi-aquatic. It had some adaptations for water, like a long neck and flipper-like arms, but also strong legs for running on land. It likely spent time both in water and on land.1
