Late Mesozoic stratigraphy in western Liaoning, China: A review

Based on progress in stratigraphic and paleontological studies, we discuss the subdivision of Late Mesozoic strata in western Liaoning, focusing on the controversies surrounding the relationship of the Jiufotang and Shahai formations, and whether or not the Zhanglaogongtun and Banlashan formations exist as distinct lithologic units. We describe the Late Mesozoic strata at representative sections associated with the new discoveries. We also discuss the correlation of Late Mesozoic strata between western Liaoning and eastern Heilongjiang and their implications for the ages of the strata in Liaoning.
