Jinfengopteryx

名字的意思： “golden phoenix feather”1

Jinfengopteryx was a small, feathered dinosaur that lived about 122 million years ago in what is now China. It had long tail feathers and may have been able to glide or fly short distances. Scientists are still debating whether it was a bird or a close cousin of birds.1 2

趣味知識

Jinfengopteryx is known from a single nearly complete skeleton that includes impressions of feathers around its neck, body, hips, legs, and tail.1

Its tail feathers were long and vaned, getting longer toward the tip of the tail.1

Unlike some other feathered dinosaurs, Jinfengopteryx did not have flight feathers on its hind legs.1

The fossil of Jinfengopteryx contains several small, reddish-yellow oval structures that might be seeds it ate, or possibly eggs or follicles.1

Some scientists think Jinfengopteryx was a troodontid, a group of smart, bird-like dinosaurs, because of its enlarged claw on the second toe.1

A 2020 study found that Jinfengopteryx had flight abilities similar to other flying non-avian theropods like Microraptor.1

Jinfengopteryx lived during the Early Cretaceous period, about 122 million years ago.1

?How big was Jinfengopteryx?

It was about 55 centimetres long, roughly the size of a crow.1 5

?Did Jinfengopteryx have feathers?

Yes, it had feathers around its neck, body, hips, legs, and tail, including long vaned tail feathers.1

?Could Jinfengopteryx fly?

A 2020 study found that its flight abilities were similar to other flying non-avian theropods like Microraptor, so it could probably glide or fly short distances.1

?What did Jinfengopteryx eat?

It may have been an omnivore. Its fossil contains small oval structures that could be seeds it ate, though they might also be eggs or follicles.1

迷思破解王

迷思： Jinfengopteryx is a true bird like Archaeopteryx.

真相： Most scientists now think Jinfengopteryx was a troodontid dinosaur, not a bird, because of its skeleton and teeth.1
