Caudipteryx amidst Williamsonia

Peacock-sized theropod dinosaurs of the genus Caudipteryx wander a landscape dominated by cycad-like seed plants of the genus Williamsonia 125 million years ago in what is today China.

Caudipteryx was a maniraptoran with a combination of reptile and bird-like features, including soft downy feathers that covered its body and a broad feathered tail. It could not fly, but was probably a swift runner.
