The wide distribution in time and space of some fossils is on account of similar ecological niches, climatic conditions and geographical history prevalent most of the parts of c. and s. Indian regions. The animals seem to have had a zonal distribution in these parts without any definite ecological barriers between them Most of the forms appear to be the late survivals from the Siwaliks, having migrated to other suitable areas in India, especially the Narmada-Godavari complex, when the conditions in the n.-w. became unfavourable on account of glaciation.
