This chapter characterizes the Siwaliks and Neogene evolutionary biology in South Asia, paying special attention to the distribution of fossiliferous terrestrial deposits of late Cenozoic age across the Indian Subcontinent and the development of a chronostratigraphic framework in Pakistan and India. The Siwalik Group is a thick and laterally expansive wedge of sub-Himalayan nonmarine clastic deposits best developed in the northern Indian Subcontinent, extending southeastward through Nepal and into Assam. Siwalik deposits helped vertebrate fossils from southern Asia become known to the Western world as early as the 1830s. The transformative factor that led to accurate dating of the Siwaliks was the application of magnetostratigraphy to detailed biostratigraphic sections. This chapter discusses the significance of the Siwalik deposits as a window on a subtropical ecosystem of the Miocene world, a window that was open during the late Paleogene and most of the Neogene.
