This aspect, taken in conjunction with other environmental interpretations based on paleo-dietary inferences deciphered from the meso-and micro-wear analysis of cheek teeth of several other mammalian groups as well as the changes in stable Carbon and Oxygen isotopes analyses on carbonate nodules of paleosols, could be used towards a better understanding of the local environment and regional climate changes during the Neogene in South Asia.
