酷東西

趣味知識

The name Serikornis means 'silken bird' because of its beautiful, feathery coat.1

It had long feathers on its hind legs all the way down to its toes, which is unusual for a ground-dwelling dinosaur.1

The feathers on its arms were symmetrical and didn't have tiny hooks called barbules, so they weren't good for flying.1

Serikornis lived during the Late Jurassic period, about 161 to 155 million years ago.2

It is only known from one complete skeleton found at Daxishan in Liaoning, China.5 2

Scientists think Serikornis was a ground-dwelling dinosaur that did not climb trees or fly.1
