Contact Dr.Jyotsana Rai, Senior Scientist, Birbal Sahni Institute of Palaeobotany, Lucknow who has compiled a comprehensive volume on nannofossils of India based on her research and extensive literature survey. She is also available in researchgate.

Definitely contact the Birbal Sahni Institute - they may have a database.  I'm not aware of a readily available database, but there is a good paper on the palynological zonations of the Permian - early Cretaceous: http://www.dli.gov.in/data_copy/upload/INSA/INSA_1/20005ab3_329.pdf.   There have been a lot of papers on the Cretaceous - Miocene Palynology of India, including zonations, but you'll have to mine individual papers.  I recommend the works of B. Nandi (1990 and 2002 with S. Chattopadhyay) as starting points, and also the 1994 work by N.N. Dogra in Cretaceous Research. Dogra is on ResearchGate. 

Dear Avik

Some limited data which deals with Paleomap of India were recorded. You can check links below:
