Beipiaosaurus
Beipiaosaurus is a therizinosaur theropod dinosaur. It lived in the Lower Cretaceous, about 125 million years ago. Its fossil was found in the Yixian Formation near Beipiao, Liaoning Province of China. The theroziosaurs were a group of theropods which became herbivorous. Beipiaosaurus had a toothless beak, cheek teeth, and protofeathers.

Jianchangosaurus Restoration
Life restoration of an individual of the primitive Asian therizinosaurs Beipiaosaurus inexpectus. At least three specimens (IVPP V11559, STM 31-1 and BMNHC PH000911) preserve EBFFs (elongated broad filamentous feathers) which are primitive, filamentous feathers. BMNHC PH000911 was inferred to have had a brownish colouration.
