De Terra and Paterson first recognized a series of sediments in the NARMADA river yielding animal fossils and Stone Age tools. The best sections of these deposits were noticed between Hoshangabad and Narsinghpur. They comprised three units (groups) each consisting of gravel or conglomerate at the base overlaid by silt or clay, while at the bottom of the whole sequence was laterite. On faunal basis de Terra considered the basal conglomerate as equivalent to the Second Glaciation (Middle Pleistocene). Subsequent work on this valley by several scholars has suggested variation in this stratigraphic order of the deposits, but the main features do not show much difference.
