Djadokhta Formation correlative strata in Chinese Inner Mongolia: an overview of the stratigraphy, sedimentary geology, and paleontology and comparisons with the type locality in the pre-Altai Gobi
Because the Bayan Mandahu redbeds of Inner Mongolia share similar sedimentary facies and fossil assemblages with the Djadokhta Formation of pre-Altai Gobi, the two units are interpreted asExpand
