作者在研究梅加拉亚盆地(Meghalaya)晚白垩世,特别是白垩-第三纪界线附近孢粉时发现大量三突口器类以及其他类型的花粉,这些花粉主要包括:Aquilapollenites indicus,A.nemuroensis,A.truncatus sp.nov.,以及新属Farabeipollis,该新属包括3个新种;还有Integricorpus brevicolpatum sp.nov.,Integricorpus langparensis sp.nov.,Mancicorpus albertensis,Striaticorpus pyriforme,S.striatum。孢粉地层学研究显示早马斯特里赫期孢粉植物群中正型粉类居统治地位,而三突口器类花粉的种类和数量都较少。三突口器类花粉是在晚白垩世正型粉类消失后才开始分异发育的。
The authors identified a large number of triple-buccal mucosa and other types of pollen found during the Late Cretaceous, especially in the vicinity of the Cretaceous-Tertiary boundary of the Meghalaya Basin. These pollen mainly include: Aquilapollenites indicus, nemuroensis, A.truncatus sp. nov., and the new genus Farabeipollis, which includes three new species; and Integricorpus brevicolpatum sp. nov., Integricorpus langparensis sp. nov., Mancicorpus albertensis, Striaticorpus pyriforme, S.striatum. Spore-pollen stratigraphy studies showed that positive Masaharu dominates in the early Maastrichian sporopollen assemblages, while the number and type of pollens in the triple-buccal pollination are less. Three bursts of pollen in the Late Cretaceous positive powder disappeared only after the differentiation of development.
