摘要
中国东北地区东部白垩纪陆相地层发育,富含动、植物化石,并形成了重要的煤及油页岩等矿产.这里还保存了我国除西藏外唯一的早白垩世最早期海相地层的记录,对研究我国白垩纪古地理具有重要意义.近年来,这一地区在白垩纪地层古生物研究中有许多新发现,其中有些新发现还填补了东北地区某些地层“空白”.本文简要介绍上述新发现并对这一地区晚白垩世植物群与以恐龙为代表的动物群的协同演化做初步探讨.
The Cretaceous continental strata developed in eastern Northeast China are rich in animal and plant fossils and have formed important minerals such as coal and oil shale.The only records of the earliest marine strata in Early Cretaceous are also preserved here besides Tibet,which is of great significance for the study on Cretaceous geography in China.Many new discoveries have been made in the Cretaceous stratigraphy of this area in recent years,some of which have filled the gaps of strata study in Northeast China.The paper also preliminarily discusses the co-evolution of Late Cretaceous flora and fauna represented by dinosaurs in the region.
