Abstract

Dispersed fossil pollen grains of Fagaceae from the Eocene sediments of the south of Primorskii Region have been analyzed using a scanning electron microscope. Fourteen types of Fagaceae pollen were identified: one of them represented the extinct genus Eotrigonobalanus, four were assigned to the subfamily Castaneoideae, two to the genus Fagus, and seven to the genus Quercus; four of the latter were produced by deciduous oaks (Quercus), one, by evergreen oaks (Cyclobalanoides), and two, by evergreen sclerophyllous oaks (Heterobalanus). The presence of pollen of the extinct genus Eotrigonobalanus in the study region was demonstrated for the first time. The data obtained are indicative of considerable diversity of the family Fagaceae in the Eocene of Primorskii Region.

滨海边疆区南部始新世古植物中的菊科：分类学和形态学的新数据

摘要

使用扫描电子显微镜分析了滨海边疆区南部始新世沉积物中的菊科植物化石分散花粉粒。鉴定了14种类型的菊科花粉：其中一种代表灭绝的真三叶草属，四种属于栗木亚科，两类属于Fagus属，七种属于栎属。后者中的四种是由落叶栎（Quercus）生产的，一种是由常绿橡树（Cyclobalanoides）生产的，另外两种是由常绿硬叶橡树（Heterobalanus）生产的。灭绝的埃特氏线虫的花粉的存在在研究区域中首次进行了演示。所获得的数据表明滨海边疆地区始新世的菊科植物的多样性。
