Multiple strata at the site evinced two periods of occupation: an earlier period evidenced by microlithic tools and ceramics, and a later period characterized by Lustrous [Red Ware]. Gregory Possehl states that "Oriyo Timbo also produced some radio carbon dates for the micro lithic occupation which indicate that this can be dated to the entirethird millennium, possibly extending as far back in time as c. 3700 BC" and hunter-gatherers were present in this area at the time when Lothal was occupied.
