Eosinopteryx brevipenna (Godefroit et al. 2013, Middle-Late Jurassic, Tiaojishan Formation, YFGP-T5197, 30 cm, 12 in long) was a feathered theropod dinosaur. The forelimb feathers were quite long (Fig. 1), but the tail feathers were not. Note the short coracoid, not good for flapping. This taxon just precedes the appearance of the first bird Archaeopteryx and succeeds Aurornis.
Overall smaller, the snout was reduced. The cranium was broader. The naris was rotated dorsally. The coracoid was larger, not deeper. The pubis was shorter.
