This book reports the recent discoveries on early angiosperms and their associated plant fossils from the Upper Jurassic Jianshangou Formation ( generally equivalent to the "Jianshangou Bed" of the lower part of the Yixian Formation, considered here to be about 145 Ma in age ) of western Liaoning, Northeast China. Focusing on the early angiosperms represented by Archaefructus, the whole Jianshangou flora from western Liaoning is described. The authors have discussed the geological and geographical background of the first occurrence for the earliest known angiosperms in Northeast China during the late Jurassic and reviewed their recent hypothesis on the " Eastern Asian center of angiosperm origin". The geological age of the Jianshangou Formation, newly named by the present authors, is suggested to be late Jurassic baded mainly upon the fossil plants. In addition, the subdivision of the main evolutionary stages of early angiosperms in Northeast China and their comparisons to the relevant equivalent floras from Kazakhslan, Mongolia, eastern Russia, and even North America and Europe, is discussed also in the book.
This book includes 12 chapters, 75 plates, 48 textfigures and 5 tables. There are 88 species belonging to 56 genera, including 4 new genera, 41 new species and 4 new combinations or eemendations to the previous taxa concerned, described in the book. Both the Chinese and English version are provided in this book. Two species of archaefructus are reported here in detail This is a comprehensive presentation of a flora in which early angiosperms are also associated.
