Schizooura had a forked tail made of long feathers with a deep notch in the middle, a shape never seen before in any bird from the Mesozoic Era.1

Its beak had no teeth, which is different from many other early birds.2 1

The furcula, or wishbone, was V-shaped and had a short hypocleidium, a feature never before reported in an Early Cretaceous ornithurine bird.1

The deltopectoral crest on its upper arm bone was big and stretched for half the length of the humerus.1

Only one fossil of Schizooura has ever been found, so scientists still have a lot to learn about it.2

It lived in a wooded environment, based on the Jehol Biota where it was discovered.1

Schizooura: AAk egindako irudia — Schizooura nolakoa izan zitekeen erakusten duen AAk egindako irudia, ordenagailu batek zientzialariek dakitenetik sortua. Asmakizun bat da: benetako animalia desberdina izan zitekeen, eta inork ez daki zein ziren bere benetako koloreak.

Oraindik eztabaidagai: Scientists are not sure exactly how Schizooura used its forked tail, because a forked tail is less efficient for flying than a fan-shaped tail but helps with attracting mates.1
