About Scansoriopteryx:

Like the feathered theropod to which it's most closely related--Epidendrosaurus--Scansoriopteryx is thought to have spent most of its life high up in trees, where it poked out grubs from underneath bark with its unusually long middle fingers. However, it's not clear if this dino-bird was covered with feathers, and it appears to have been incapable of flight. So far, this genus is known only by the fossil of a single juvenile; future discoveries should shed further light on its appearance and behavior.
