Research Project:

Responses of Biota to a Sudden Global Warming Event in an Overall Cooling Phase of the Earth

The present day atmosphere is under a serious threat due to unbridled usage of fossil fuels, CO2 emission and global warming. Studying similar climatic conditions from the past is one of the best way to mitigate the situation in future. An abrupt warming of Bartonian ( i.e.~ 40 Ma ago from now) age within a major cooling phase is comparable to the present situation. The effects of warming on the morphology and diversification of Bartonian  bivalves will be studied to parameterise the climate model.

The calcium carbonate shells of bivalves are excellent recorders of the palaeoclimatic conditions at very high resolution down to seasonal variability. Oysters, a cementing bivalve family spend their whole life in a fixed substratum. Thus, they can experience all the seasonality, temperature and environmental variation of a specific location throughout their life. Kutch, a paleoequatorial basin of western coast, India hosts a huge abundance of oysters from Bartonian age of late Eocene epoch. Stable isotope analysis will be adopted for identification of hyperthermal event(s). Cathodoluminescence, Raman Spectroscopy, micro X-rays fluorescence and scanning electron microscopy will be used for identification of seasonal growth pattern within the shells and (if) any morphological adjustment, associated with the global warming.
