一般认为,在白垩纪及其晚期(80~65Ma前),地球上的气候特别温暖,甚至在极区都有恐龙类生活;但是,最近有文献(其中含有证据)表明,在白垩纪晚期冰水的周期性(冰川的前进和后退)仍然存在。美国的古海洋学家、古气候学家及冰川专家在米勒(Miller)的领导下详细研究了钻获的沉积岩标本
It is generally accepted that the Earth’s climate was particularly warm during the Cretaceous and its late (80-65 Ma) years and even dinosaurs lived in the polar regions; however, recent literature (which contains evidence) suggests that in late Cretaceous ice The periodic nature of water (the advance and retreat of glaciers) still exists. Under the leadership of Miller, paleoclimatologists and glaciologists from the United States studied in detail the sedimentary rock samples
