Additional dinoflagellates and acritarchs from grey shale member of Dalmiapuram formation, South India


  • K.P. Jain Birbal Sahni Institute of Palaeobotany, 53, University Road, Lucknow 226007, India



The present communication is a continuation of two previous reports published by Jain and Subba-raman (1969) and Jain and Taugourdeau-Lantz (1973). Additional palaeophytoplankton taxa described from the present material, alongwith the known ones project a complete picture of dinoflagellate and acritarch assemblage from the Grey Shale Member of Dalmiapuram Formation, South India. Fluctuations in the environment of deposition within the exposed section have been indicated.

The present microplankton assemblage includes 38 genera and 59 distinct species, out of these 13 species are new. The Grey Shale Member has been assigned an Early Albian age.
