This article highlights the findings of some of the major collaborative studies conducted by the staff of the Birbal Sahni Institute of Palaeobotany during 2014. The article provides a glimpse of ongoing research at BSIP in diverse fields under the umbrella of palaeosciences, such as the origin and evolution of biota, palaeobiogeography, deep time and Quaternary palaeoclimates and palaeocology, archaeobotany and dating.Keywords

We report the first record of an age-diagnostic, but depauperate assemblage of calcareous nannofossils, an exclusively marine phytoplankton group, from the Lathi Formation of Jaisalmer Basin, western India. The nannofossil evidence, precisely constrains the age of the Lathi Formation, traditionally considered to be a Bajocian (Middle Jurassic) continental deposit. Furthermore, the presence of several reworked nannofossil taxa of Pliensbachian, Toarcian and Aalenian ages suggests that the earliest epeiric sea transgressed western India during the Early Jurassic. Thick and luxuriant gymnosperm forests proliferated in the Jaisalmer Basin during this time. The presence of calcareous nannofossils in both the lower and upper members of the Lathi Formation (Odania and Thaiat members) points to intermittent coastal marine depositional environment.Keywords
