Abstract
Megaspores from the uppermost horizon of Raniganj Formation and the lowermost strata of Panchet Formation exposed in the Raniganj Coalfield, West Bengal, have been analysed both qualitatively and quantitatively. The assemblage recovered from the Raniganj Formation qualitatively comprises Banksisporites psilatus (Bharadwaj & Tiwari) comb, nov., B. panchetensis (Maheshwari & Banerji) Banerji et al., Biharisporites maiturensis Maheshwari & Banerji, B. raniganjensis sp. nov. and Maiturisporites indicus Maheshwari & Banerji. The genus BIHARISPORITES is the most commonly occurring from in this assemblage. The Maitur Member of Panchet Formation yields Banksisporites panchetensis (Maheshwari & Banerji) Banerji et al., B. gondwanensis Maheshwari & Banerji, B. granulosus Maheshwari & Banerji, Biharisporites maiturensis Maheshwari & Banerji, B. luguensis Pal et al., Verrutriletes obscurus (Maheswari & Banerji) Banerji et al., V. distinctus (Maheshwari & Banerji) Banerji et al., Talchirella sinuata Maheshwari & Banerji, T. dubia Maheshwari & Banerji, T. flavata (Kar) Bharadwaj&Tiwari, Pantiella bosei Maheshwari & Banerji, P. bharadwajii Maheshwari&Banerji, P. maheshwarii sp. nov., Maiturisporites indicus Maheshwari & Banerji, M. distinctus Maheshwari & Banerji, M. spinotriletus Maheshwari & Banerji and M. banerjii sp. nov. Some abnormal forms with tetralete sutures have also been recovered from this horizon. Maitur assemblage is characterized by the preponderance of the genus MAITURISPORITES followed by BANKSISPORITES.
