吃：肉早期鳥類白堊紀早期

Paraprotopteryx was a tiny bird that lived in the Early Cretaceous period, about 122 million years ago. It had four long, ribbon-like tail feathers that were longer than its whole body! These feathers may have been used to show off to other birds.1

趣味知識

Paraprotopteryx is one of the earliest birds known to have four long tail feathers, which may have been used for display.1

Its wishbone (furcula) was Y-shaped with a very narrow angle between the two branches.1

The fossil of Paraprotopteryx was originally thought to be from the Yixian Formation, but later studies showed it came from the Huajiying Formation.1

Some scientists think the second pair of tail feathers might be a fake added by fossil traders, but the first pair is definitely real.1

Paraprotopteryx lived during the Hauterivian age of the Early Cretaceous, about 132 to 125 million years ago.2

迷思破解王

迷思： Paraprotopteryx is a dinosaur.

真相： Paraprotopteryx is a bird, but birds are a type of dinosaur called avialan dinosaurs. So it is both a bird and a dinosaur!1
