///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 w:st="on">Jiaolai w:st="on">Basin of eastern w:st="on">w:st="on">Shandong Province, w:st="on">China. Sedimentary successions and facies associations of the w:st="on">w:st="on">Cretaceous w:st="on">Jiaolai w:st="on">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 w:st="on">w:st="on">Jiaolai w:st="on">Basin and its paleogeographic environment, paleoecology and dinosaur fauna in the Cretaceous are briefly discussed as well.
