Recent fieldwork has extended the distribution of the Daohugou Bed deposits from the Daohugou Village to its several neighboring areas. The fossil-bearing Daohugou deposits uncomformably overlie complex bedrocks, and com- prise three major parts. The red shales in the lower part were misidentified as belonging to the Tuchengzi Formation. Field excavation has indicated that the shales of upper part of the bed are the major fossil-bearing horizon. Due to strong tectonic activities, sediments were often folded with the se- quences inverted in the region. Some newly recognized con- tacts between the Daohugou Bed and the volcanic rocks showed that the ignimbrite of the Tiaojishan Formation (159―164 Ma) underlies the Daohugou deposits, rather than overlying the latter as previously proposed. Thus, the age of the Daohugou deposits should be younger than the age of the ignimbrite, and thus it was incorrect to correlate the Dao- hugou Bed with the Middle Jurassic Jiulongshan Formation. Although biostratigraphic studies based on conchostracans and insects support a Middle Jurassic-early Late Jurassic age for the Daohugou deposits, vertebrate fossils such as Liaoxitriton, Jeholopterus and feathered maniraptorans show much resemblance to those of the Yixian Formation. In other words, despite the absence of Lycoptera, a typical fish of the Jehol Biota, the Daohugou vertebrate assemblage is closer to that of the Early Cretaceous Jehol Biota than to any other biota. We propose that the Daohugou fossil assemblage probably represents the earliest evolutionary stage of the Jehol Biota based on both vertebrate biostratigraphy and the sedimentological and volcanic features which suggest the Daohugou deposit belongs to the same cycle of volcanism and sedimentation as the Yixian Formation of the Jehol Group.

In the present paper the anatomical charctrters and morphologival variatin of lyciotera longicarpjalus found from western lianing are reviewed, lycoptera long-icephalus Liu et al. 1963 is emended to Jinanichthys longicephalus (Liu et al. )Li-aosiichthys Su 1992 is considered as a synonym of Jinanichthys. The evolutionary trend and systematic of jinanichthys are discussed.

Large samples of fossil fishes were collected from the Late Mesozoic non-ma-rine Jehol Group (including the Yixian, Jiufotang, Shahai and Fuxin formations inascending order) at 25 localities in western Liaoning, China (Fig.1, Table 1). Thenew material enriches the composition of the Jehol fish fauna greatly. Our preli-minary study indicates that this fish fauna is dominated by sturgeons (Peipiaosteidae:Yanosteus longidorsalis and Peipiaosteus pani), paddlefishes (Polyodontidae: Protopse-phurus liui), diversified lycopterids (Lycoptera dagidi, L. muroii, L. sinensis, ***, and Jinanichthys longiccphalus), osteoglossids (Paralycoptera sp.),and possibly osteoglossomorphs (Huashia sp., ?Nieerkunia and an indeterminatefish); it also includes palaeonisciforms, amiiforms (Sinamia sp.), and a teleost incer-tae sedis (Longdeichthys luoiiaxiaensis)

In this article we describe a new and excep-tionally well-preserved pterodactyloid pterosaur, Sinopterus dongi gen. et sp. nov. from the Jiufotang Formation in west-ern Liaoning Province of northeast China. The new species is referred to the family Tapejaridae, representing its first re-cord outside Brazil. It also represents the earliest occurrence as well as the most complete skeleton of the family. Some revisions are made about the family according to the mor-phological observations of the postcranial bones of Sinop-terus. Two pterosaur assemblages appear to have existed in the Jehol Group, represented by the lower Yixian Formation and upper Jiufotang Formation, respectively. The lower pterosaur assemblage shows some resemblance to that of the Late Jurassic in Solnhofen (Tithonian) by sharing members of the Pterodactylidae and Anurognathidae. The upper one shows more resemblance to that of the Early Cretaceous Santana Formation (Aptian/Albian) by comprising only pterodactyloids such as the Tapejaridae. The age of the Yixian Formation is younger than that of the Solnhofen lithographic limestone, and the age of the Jiufotang Forma-tion (Aptian) is slightly older than the Santana Formation.
