Most reconstructions of the data conclude that the settlements with Classical Harappan Sorath Tradition traits in Gujarat were engaged in the production and trade of non-perishable Harappan-style goods, while the Agro-pastoralism settlements with Sorath traits focused on agro-pastoralism. To date, no major attempt has been made to un- Carbon isotopes derstand the nature of the agro-pastoralism practiced in these Sorath settlements. This pilot study based on the Oxygen isotopes ff Strontium isotopes oxygen and carbon isotope data from cattle/bu alo, sheep, and sheep/goat teeth from the Sorath settlement of Kotada Bhadli (2400–2000 BCE) suggests that this settlement was indeed engaged in specialized seasonal herding of the domesticated animals. Comparing these data with published data on cattle/buffalo, sheep and goat from the nearby Harappan settlement of Bagasra indicates that a distinct form of sedentary animal hus- bandry was practiced at the site of Kotada Bhadli, the nature of which is considerably different from that practiced at the permanent settlement of Bagasra. At Kotada Bhadli both wild flora and agricultural waste were utilized as fodder, depending on their seasonal availability. Such seasonal availability, and the diversification of fodder selection may suggest a regional adaptation to the local climate by the agro-pastoralists during the Late phase of the Mature period (2300–1900 BCE) of the Indus Civilization. The strontium isotopes from the tooth enamel suggest the domesticates consumed at Kotada Bhadli were most likely raised locally, with a grazing catchment not extending far from the settlement. The results also suggest that at least in Gujarat during the Mature period of the Indus Civilization, carbon isotope values along with tooth morphology might be used to distinguish between sheep and goats, due to human practices involving the deliberate use of millets as fodder for sheep but much less so for goats. 1.

The results will be compared craft activities and trade due to its naturally available resources and its with the published results of biogenic isotopes from the site of Bagasra, location near to the sea that helped in facilitating trade networks. The the only Harappan site from Gujarat that has published isotope data economy of Gujarat during the Indus Civilization was not only limited from domesticated animals. We also compare the strontium isotope to the production and trade of Harappan style objects; agro-pastoralism values of the domesticated animals consumed at the site of Kotada also played an important role in the regional economy of Gujarat.
