"The first radiocarbon date from charcoal included in the mortar of a collapsed pillar lying overturned in the riverbed at Sann (Eastern) Gate, Ranikot, confirms that at least this sector of the fort was built, or repaired, between the beginning of the XVIII and the beginning of XIX century AD, that is between the beginning of the Kalhoras and the beginning of the Talpurs rule. The present note, without positively solving the much debated issue of the age of the fort, points to a new line of research on the topic, which deserves future work, in order to collect more organic material for absolute dating."
