Eosinopteryx brevipenna is a small feathered dinosaur, 30 cm in length, from the early part of the Late Jurassic (approximately 160 million years ago) of northwestern China. It is known from a single, complete articulated skeleton with feathers. The original describers of this species suggested it shows a reduced plumage (covering of feathers) relative to other contemporary and closely related feathered dinosaurs, and that this might indicate a ground-dwelling, fast-running way of life.
