Cretaceous fossil flowers and inflorescences bearing pollen in situ.
The main aim of the project is to study flowers, inflorescences and pollen in situ at fossil plants of the Peruc-Korycany Formation within the Bohemian Cretaceous Basin. Methodology which have not yet been applied, will be used. The project is focused on detailed study of flowers and their pollen ncluding study of exina sculptation (using high resolution SEM) and pollen ultrastructures (using TEM). The project follows up with results of previously finished projects on infructescences, fruits and seeds. Another aim of the project is to compare pollen grains known from dispersed pollen spectra with pollen found in situ. This will help to determine systematical affinity of pollen grains classified till now only by names of formal palynomorph nomenclature. New data on Cretaceous plants and their pollen in situ will be used for palaeoecological interpretations and reconstructions for purposes of exhibition of the National Museum and lectures on palaeontology in the Charles University.
