Early Cretaceous acolumellate semitectate pollen from Egypt
£1.00
Scanning electron microscope observations were made of more than one thousand specimens of acolumellate semitectate pollen, all of which originate from the borehole Mersa Matruh 1, North-West Desert, Egypt. The detail observed enables thirteen forms to be distinguished from this set of specimens. It is suggested that the acolumellate pollen group should be separated from affinities with described columellate taxa. The newly described variety in this group gives it improved stratigraphic value.
