///The core issue of taphonomy is to study the sedimentary facies of fossil-bearing rocks, reconstruct their depositional environments, and understand the paleogeographical background before and after the burying of fossils at different scales. The terrestrial Cretaceous Laiyang, Qingshan and Wangshi groups (130~65 Ma), in ascending order, are widely distributed in Jiaolai Basin of eastern Shandong Province, China. Sedimentary successions and facies associations of the Cretaceous Jiaolai Basin indicate an evolution of basin and sedimentary paleogeography, i.e., from alluvial-lacustrine environment in humid and warm climate in the Early Cretaceous to an alluvial environment in hot and drought climate towards the Late Cretaceous. Furthermore, evolution of Jiaolai Basin and its paleogeographic environment, paleoecology and dinosaur fauna in the Cretaceous are briefly discussed as well.
