首次在阳江盆地鹿母湾组上部层位采获孢粉化石,建立Pterisisporites-Classopollis-Exesipollenites组合,它以高含量的裸子植物花粉、稀少的蕨类植物孢子和未见被子植物花粉为特征。文中详细论述了组合中主要孢粉的地史分布,认为本组合的地质时代为早白垩世中晚期。
For the first time, sporopollen fossils were harvested in the upper part of the Luomuwan Formation in the Yangjiang basin. Pterisisporites-Classopollis-Exesipollenites combinations were established. They are characterized by high levels of pollen of gymnosperms, spores of rare fern and no pollen of angiosperm. The article discusses in detail the geosphere distribution of the main sporopollen in this assemblage, and considers that the geologic age of this assemblage is mid to late Early Cretaceous.
