Jinfengopteryx
''Jinfengopteryx'' (from ''Jinfeng'', 'golden phoenix', the queen of birds in Chinese folklore, and Ancient Greek πτερυξ ''pteryx'', meaning 'feather') is a genus of maniraptoran dinosaur. It was found in the Qiaotou member of the Huajiying Formation of Hebei Province, China, and is therefore of uncertain age. The Qiaotou Member may correlate with the more well-known Early Cretaceous Yixian Formation, and so probably dates to around 122 Ma ago.〔Jin, F., Zhang, F.C., Li, Z.H., Zhang, J.Y., Li, C. and Zhou, Z.H. (2008). "On the horizon of ''Protopteryx'' and the early vertebrate fossil assemblages of the Jehol Biota." ''Chinese Science Bulletin'', 53(18): 2820-2827.〕
==Description==
''Jinfengopteryx'' is known from one specimen (number CAGS-IG-04-0801), a nearly complete articulated skeleton, which measured 55 cm (2 ft) long. It was preserved with extensive impressions of pennaceous feathers, but it lacks flight feathers on its hind legs, which are present in related dinosaurs such as ''Pedopenna'' or ''Anchiornis''. It also preserves several small, oval structures that are reddish yellow in color, probably seeds that the dinosaur had eaten before it died.〔Ji, Q., Ji, S., Lu, J., You, H., Chen, W., Liu, Y., and Liu, Y. (2005). "First avialan bird from China (''Jinfengopteryx elegans'' gen. et sp. nov.)." ''Geological Bulletin of China'', 24(3): 197-205.〕 The diet is unsure. Despite being a theropod, it could have been a herbivore.〔Lindsay E. Zanno, David D. Gillette, L. Barry Albright and Alan L. Titus (2009) ''A new North American therizinosaurid and the role of herbivory in ‘predatory’ dinosaur evolution.'' Proc. R. Soc. B 276, p. 3508 (doi:10.1098/rspb.2009.1029 )〕
