Fossil Spores and Pollen in Crude Oils

2015
Crude oils from both inland and coastal shelf basins were analyzed for their spores and pollen content. The inland petroliferous basins include the Tarim, Junggar, Turpan, Qaidam, and Jiuquan basins in West China. The coastal shelf petroliferous basins include the Liaohe, Beibu Gulf, and Zhujiang Mouth basins in the East and South China Seas.

The fossil pollen genus Classopollis

Lethaia, 1976
The generic name Classopollis Pflug, 1953, is considered as a valid usable name for Mesozoic spherical pollen characterized by a subequatorial circumpolar canal, a thickened equatorial band, a distal cryptopore, and a proximal tetrad scar. A study of Classopollis exine revealed the absence of nexine.

The Quaternary Research (Daiyonki-Kenkyu), 1965
It will be necessary to classify fossil pollen on a level of species instead of genus for the purpose to obtain more accurate knowledges of paleoflora, paleoecology, paleoclimate and detailed correlation of sediments in which the pollen is contained.
