胶莱盆地恐龙足迹化石及其古生态、古地理意义

With increasing booming of the origin study of fossil birds and dinosaurs, dinosaur footprints study, because of its irreplaceable status in behavioral and ecological reconstruction, has become a multidisciplinary subjects –crossed research fields. After the implementation of the one–year-lasting NSFC project entitled “Dinosaur footprints from the Jiaolai Basin and their plaeoecological and paleogeographical significances”, dinosaur footprints-related field surveys were conducted three times in total and 5 larger fossil localities were discovered in Linyi area，.western Shandong province. This demonstrate that dinosaur tracks are not only limited to eastern Shandong (mainly the Jiaolai Basin), but also distributed in large in the western part. It is especially needed to pointed out that Jurassic dinosaur tracks were first discovered from the Santai Formation in Mengyin County during our field trip, and this is the first discovery in Sandong.Province (Li Rihui et al. 2002). Also detected are lot of well preserved suropod tracks and minor amount of dinosaur footprints accompanied fossil bird tracks, both of the discoveries are also the first time in Shandong area.In conclusion, dinosaur tracks in Shandong area are characterized by large in number,variable diversity in type, and perfection in preservation, which is seldom seen at home and.abroad.Systematically study of dinosaur tracks in Shandong area, is of particular importance to probe.the behavioral and ecological feathers, reconstruct the community component and relationships of track-making dinosaurs. At the same time, comparative study of dinosaur tracks to the ones from adjacent areas, such as northeastern China, Japan, Korea, combined with the research of dinosaur.bones, could reconstruct dinosaur paleogeography of Northeast Asia and provide new evidence for the reconstruction of paleogeographical evolution in the area.

通过对胶莱盆地下白垩统莱阳群恐龙足迹化石分布区域与层位、足迹特征及个体生态与群落生态的系统研究，对恢复该地区恐龙的群落组成，探索其行为习性、生态特点以及恐龙动物群间的相互关系具有重要意义。同时，通过与我国东北地区、日本、韩国等地同时期恐龙足迹的比较研究，结合前人恐龙骨格化石的研究成果，可望恢复东北亚早白垩世恐龙古地理。
