In 1996, it was determined that the early humans passed through this area during their transition from Africa to Europe.
There is no immediate obsidian outcrop near the site, therefore, the excavators during the 1974 excavations hypothesized that the material was obtained from afar. Years later, a chemical analysis of the obsidian revealed three originating sources: Assebot, Kone, and Ayelu. Ayelu is situated near the town of Gewane, at 150 km north-west of Porc ...
Even though many of these sites contain only few Ubaid style sherds the great deal of imported pottery and obsidian at Dosariyah suggests its relevance within an extensive social and economic network. Several, up to 50 cm thick layers containing mostly shells of pearl oyster Pinctada radiata could be seen as evidence for pearling.
Radiocarbon dating of charcoal fragments yielded a date of between 17,600 and 20,500 years ago, making it the oldest structure yet discovered in Japan. In addition, about 180 stone spearheads mainly made of obsidian from Nagano Prefecture , the Izu Peninsula or the Hakone area were found, providing evidence of surprisingly long-distance trade ...
