Palaeoclimatic studies of India with the help of palaeobotanical evidences in tertiary period

The present day distribution of plants shows that certain environments are characterised by certain plant communities peculiar to them. The environmental condition under which the fossil plant, lived, are interpreted from the habitats under which their modern equivalent live. Environment is necessarily the surrounding condition influences or forces by which living things are influenced or modified in their growth and subsequent development. Climate has perhaps played the most significant role in regulating the environment of a particular region. As we know geologically India is divisible into three units (1) Peninsular, (2) Extra Peninsular and (3) Indo-Gangetic plain. The tertiary floras of India can conveniently be divided into two groups-Palaeogene and Neogene. As known today, Palaeogene flora is found only in the Peninsular India. The palaeogene flora is analysed at family level and also determined the percentages of exclusively tropical, mainly tropical, tropical and Extra-tropical, mainly Extratropical and exclusively Extratropical families. Relationship between the Palaeogene families and living tropical families is proposed as a means of evaluating the palaeoclimate of the region.
