Do you know what these two animals are?

In 1966, a small carnivorous dinosaur fossil specimen called "Sinosauropteryx" was discovered in rocks deposited about 125 million years ago in the western Liaoning region of my country. Chinese scientists discovered that the body of this dinosaur was covered with a layer of "hair"-like skin derivatives. This is the first time in history that feathers have been found on the body of a non-bird animal, and this discovery provides strong evidence for the hypothesis that birds originated from dinosaurs.
