Ambopteryx

What it was like

Ambopteryx was a tiny, tree-dwelling dinosaur with wings made of skin instead of feathers. A long, rod-like bone at each wrist helped hold up a membrane, like that of a bat, and it also had feathers on its body.

It is a close relative of Yi, the first dinosaur found with this kind of wing. It probably glided between trees rather than flew with flapping wings.

Its world

It lived in the Late Jurassic in what is now northeastern China.

How it was found

Wang and colleagues named Ambopteryx in 2019, from a single skeleton. Its fossil also held pebbles in its stomach, and the remains of its last meal, which suggest it ate both plants and small animals.
