Several useful documentation on larger foraminifera of India have appeared during last 50 years but there was no such monograph on Lower Tertiary larger foraminifera of India, supported with detail illustrations till date. The author made an attempt to fulfill this demand. This monograph will definitely be useful to the Micropalaeontologits dealing with larger foraminifera, stratigraphers and advanced students. The author has provided description and illustration of the larger foraminifera of the Eocene - Oligocene part of the succession of Cutch, India, which is the type area of Tertiary succession in India. This monograph contains those larger foraminifers which are stratigraphically important and highly dominant and rock forming. To keep the length of the monograph within the acceptable limits, the author has been selective in the number of species which could be identified by oriented, split and good rock sections. On the basis of his extensive study this comprehensive and convincing documentation could be presented.

The author is born on 2nd March 1957. After his Ph.D work in Calcutta University, he is involved in R&D projects of Geological Survey of India as Senior Geologist . The new species, erected by him are recorded in Ellis and Messina Catalogue. He has published 29 papers on Foraminifera, Bryozoa, Holocene Climatic zonation and Taphonomy.
