AFTER the publication of the fossil bird Confuciusorins, additional skeletons of fossil birds have been found by Hou Lianhai, Hu Yaoming, Wang Ping, Gu Yucai and Sun Yutie in the Yixian Formation of Beipiao, Liaoning Province. The new locality is about 3 km southwest of that of Confuciusorins. Among those specimens were two of Confuciusorins and two new birds. A well-developed carina was found on the smallest specimen, a feature not found in the Jurassic birds, such as Archaeopteryx and Confuciusorins. The new Jurassic fossil bird is described in the present note.
