three tribes lived both a sedentary pastoral and orchard farming lifestyle, and a semi-nomadic fishing, transhumance and mixed farming lifestyle. Prior to the Neolithic Revolution, Paleolithic Sicilians would have lived a hunter-gatherer lifestyle, just like most human cultures before the Neolithic. The river Salsu was the territorial boundary between the Sicels and Sicanians. They wore basic clothing made of wool, plant fibre, papyrus, esparto grass, animal skins, palm leaves, leather and fur, and created everyday tools, as well as weapons, using metal forging, woodworking and pottery. They typically lived in a nuclear family unit, with some extended family members as well, usually within a drystone hut, a neolithic long house or a simple hut made of mud, stones, wood, palm leaves or grass. Their main methods of transportation were horseback, donkeys and chariots. Evidence of pet wildcats, cirneco dogs and children's toys have been discovered in archaeological digs, especially in cemetery tombs. Their diet was a typical Mediterranean diet, including unique food varieties such as Gaglioppo, Acitana and Diamante citron, while in modern times the Calabrian Salami, which is also produced in Sicily, and sometimes used to make spicy 'Nduja spreadable paste/sauce, is a popular type of salami sold in Brazil and the Anglosphere. All 3 tribes also specialised in building megalithic single-chambered dolmen tombs, a tradition which dates back to the Neolithic. "An important archaeological site, located in Southeast Sicily, is the Necropolis of Pantalica, a collection of cemeteries with rock-cut chamber tombs. Dating from the 13th to the 7th centuries BC., recent estimates suggest a figure of just under 4,000 tombs. They extend around the flanks of a large promontory located at the junction of the Anapo river with its tributary, the Calcinara, about 23 km (14 mi) northwest of Syracuse. Together with the city of Syracuse, Pantalica was listed as a UNESCO World Heritage Site in 2005. The site was mainly excavated between 1895 and 1910 by the Italian archeologist, Paolo Orsi, although most of the tombs had already been looted long before his time. Items found within the tombs of Pantalica, some now on display at the Archaeology Museum in Syracuse, were the characteristic red-burnished pottery vessels, and metal objects, including weaponry (small knives and daggers) and clothing, such as bronze fibulae (brooches) and rings, which were placed with the deceased in the tombs. Most of the tombs contained between one to seven individuals of all
