Origin of birds
Anchiornis huxlei is so far the only dinobird fossil known which lived before Archaeopteryx. It was found in Liaoning, China. The strata dates to the mid-late Jurassic period, 160 to 155 million years ago. There are also feather-bearing non-flying dinosaurs from the Jurassic of China, such as the maniraptoran Epidexipteryx. Epidexipteryx is the earliest known example of ornamental feathers in the fossil record, about 152 to 168 million years ago.
