摘　　要：松辽盆地白垩纪生物群发育,分布广,在盆地演化的不同时期,先后出现过热河生物群,松花江生物群和明水生物群。文中较系统地总结了每个生物群的主要特征,揭示了盆地内整个生物群发育的总体面貌,纵向演化的基本特征及其在生物地层、生态环境、古气候研究中的意义。The Cretaceous biotas of Songliao Basin are divided in ascending order into the Jehol Biota in the faulted period, the Songhuajiang Biota in the depressed period and the Mingshui Biota in the atrophied period. The three major biotas are well developed and widely distributed. This paper summarizes systematically the main characters of each biota and reveals the general biota features, the general vertical distribution patterns and their significance on the research of biostratigraphy, ecological environment and paleoelimate.
