摘要
当我们研究中生代地层的时候,总不免要为一种事实所惊奇,就是许许多多在世界各地、特别是亚洲东北部,分布很广的上白垩纪被子植物,从来没有在中国同期的沉积中发现过,虽然在微体植物方面,徐仁先生等最近曾经报道过甘肃酒泉下惠回堡系上部的木兰属和胡桃属的花粉各一种。
(With 1 Plate)In studying the Mesozoic stratigraphy,one is always struck by the fact that no determinable angiospermous leaves have so fạr been found in any of the supposed late Cretaceous strata of China,though a few remains of microflora were recently recorded by Hsüand Chow[1]from the uppermost part of the Lower Huihuipou formation of Western Kansu.
