Halszkaraptor

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
