“…3) has been linked to climatic variability within the Micula prinsii Zone and confirmed an additional warming pulse before K-Pg boundary in Tethyan province. The paleoenvironmental studies from the same region, in Um Sohryngkew River section, Meghalaya provided organo-chemical evidence of incidence of "regional fire" which was possibly responsible for stepwise disappearance of planktic foraminifers in upper Maastrichtian biozones (CF4-CF3) and migration of some forms out of warm water environment (Pal et al 2018). Among the various other causes of late Maastrichtian warming, they presumed the regional fires to be one of the factors.…”

Marine micropaleontology concerns biostratigraphy for dating and correlation of deep time sequences as well as in palaeoceanography to understand the marine processes of the past. For this, marine micropalaeontology utilizes detailed studies on exclusively marine microbiota such as foraminifers, nannofossils, diatoms, dinoflagellates, and others. This article discusses (in detail) our present state of palaeoceanographic knowledge based on marine micropalaeontology studies in the Indian sector. A detailed literature survey showcases that numerous studies have been carried out in deep time (Jurassic -Neogene) as well as Quaternary sediments utilizing marine microfossils from India. These studies from different geological periods and regions within the Indian territory such as Jurassic (Kutch Basin), Cretaceous and Cretaceous-Paleogene (K-Pg) transition (western, peninsular and northeast India), Palaeogene (northeast and western India), Neogene (Andaman & Nicobar Islands, northeast Indian Ocean), Quaternary (Indian Ocean, Southern Ocean, coastal and estuarine regions of peninsular India) have provided better insights to our previous understandings on various aspects that include biostratigraphy, paleoenvironment, evolution, ocean/land-climate variability, its dynamics and teleconnections.
