Abstract

Three early Eocene pollen types, viz., Piladiporocolpites, Psiladiporocolpites, and Retidiporocolpites having diverse morphological characters but all possessing a characteristic type of aperture called ‘Diporocolpis’ are described from the bore-hole core no K12, drilled by the MECL around Kuchaur-Benia area, Bikaner District, Rajasthan. The ‘Diporocolpis’ type of aperture proposed as a new name is characterized by the presence of two equatorial pores connected by a colpus. In some genera, the margin of aperture is spinose, whereas in others the spines are absent. The exine is variously sculptured or structured.
