Activity 3 – Biotic evolution with reference to Indo-Eurasian collision, evidences for global events
Cenozoic biotic remains from the Himalaya play a vital role in unraveling the intricacies of the evolution of the Himalaya. Fauna and flora provide a robust temporal perspective to the regional and global bio-events besides correlating disjunctive sedimentary packages. The promising Paleogene successions in Himalaya are represented by Subathu, Dagshai, and Kasauli formations in northwestern part and Disang and Barail groups in northeastern part; whereas the Neogene successions are characterized by Siwalik Group in NW and Surma Group in NE. These syn- and post collisional basins bear record of inward, outward and endmecity of biota vis-à-vis growth of Himalaya and varying climate. The proposed activity aims to carry out the detailed investigations of mega and micro-fossils (vertebrates, invertebrates, and pollens) for the reconstruction of a high-resolution biostratigraphy of the Cenozoic successions of NW and NE Himalaya, in the light of India-Asia collision and global bioevents. The new data will help interpret paleoclimate variability, paleo-environment, evolution and extinction of biotic communities, paleogeography, and dispersal of mammals.
