摘要：  A Miocene bird is described as a new genus and species (Shandongornis shanwanensis) of Family Phasianidae in present note. It is the most complete fossil bird so far known in China. The specimen was found from the diatomacous shale of “Shanwang Series”of Linqu District, Shandong Province, and was sent to our Institute for determination by Shandong Provincial Museum in 1976. The specimen includes mainly the imprints of a complete skeleton, and the outline of the body, with several pieces of broken bones in situ. Because of the pressure, most imprints of the bones are in disorder. Therefore some important features of the specimen can not be observed. The diagnosis of the new genus and species is summarized as follows:
    Size medium. Skull comparatively large, bill short, massive and cone-like. Upper bill slightly longer than lower one, and with its anterior end bending little downwards, but not forming a hook.  Bones of wing developed, hind foot not much elongated, but tarso-metatarsus longer than half length of tibia. Foot anisodactylous in form, toes massive, first one higher and shorter than others.
