Field notes

About Scansoriopteryx

What it was like

Scansoriopteryx was a tiny, feathered theropod about the size of a sparrow. Its known skeleton is a young animal. Its third finger was very long, and its feet suggest it could climb trees. Its relative Yi had skin wings stretched from long fingers, and Scansoriopteryx may have had something similar.

Its world

It lived in what is now China, in forests beside lakes. The exact age of its rocks is uncertain.

How it was found

Czerkas and Yuan named Scansoriopteryx in 2002. Another name, Epidendrosaurus, was given to a very similar fossil at about the same time, and many scientists think the two are the same animal.
