| Abstract | The Tertiary deposits (subsurface and/or surface) of south India show 31 genera and 66 species of pteridophytic spores referableto Lycopodiaceae, Gleicheniaceae, Osmundaceae, Ophioglossaceae, Hymenophyllaceae, Schizaeaceae, Parkeriaceae, Pteridaceae. Cyatheaceae/Dicksoniaceae and Polypodiaceae. Both in numbers and diversity the pteridophytes were much more abundant during Neogene (Miocene) than in Palaeogene. Schizaeaceae and Polypodiaceae constitute the predominant families. Schizaeoisporites andPolypodiisporites are the best represented genera. However, Lygodiumsporites, Crassoretitriletes, Neyvelisporites, Schizaeoisporites, Pteridacidites and Polypodiisporites taken together, may be considered as characteristic of the Miocene palynoassemblage. |
