The first samples of flint stones in Iran belonging to 9000 years ago have been identified in Yeri City historical site.
Tehran, 27 November 2005 (CHN) -- The third season of archaeological excavations in the historical site of Yeri City in Ardabil province resulted in the discovery of 9000-year-old flint stones. It is the first time that traces of flint stones from pre-historic periods of Iran have been discovered.
During the Neolithic epoch, due to the increase of temperature, environmental circumstances provided human beings with greater food resources. Within this period which dated back to 9000 years ago, human beings with the use of defense and hunting instruments could set up permanent dwellings and residences and made considerable progress in making different tools such as dragger, arrow, and using flint stone.
"Discovery of tools made of flint stone in Iran is being regarded an important event in the field of archaeology, because no flint stones belonging to the prehistoric epoch were ever discovered in the country," said Alireza Hazhbari Nobari, archaeologist and head of the excavation team in Yeri City.
"It is probable that the origin of the tools is Minor Asia or Caucasus; if so the relation between the region with Caucasus and the Minor Asia within the Neolithic epoch will be approved," added Nobari. However, Nobari notes that due to the existence of a volcano in the region, it is also possible that the stones belong to the same area.
The excavations indicate that the prehistoric inhabitants of the region used flint stones for making war and hunting tools. This stone has been identified in the layers of Neolithic epoch (about 9000 years ago) in Yeri City region.
Experts of ancient tools and instruments are right now carrying out researches on the discovered stone equipments in Qusha Tepe belonging to the Neolithic epoch to identify their origin. The Neolithic layer in the area of Yeri City plain was identified underneath the Iron Age (3500 to 2550 years ago), Bronze Age (5000 years ago), and Copper and Stone ages (7000 years ago) layers.
"The consecutiveness of these layers indicates the existence of a continual life and residence in the region," explained Nobari.
Based on the condition of the layers, Nobari added that the periods had become extinct under natural conditions and there is no evidence of abnormal disasters in the area.
The stratigraphy of the first layer of Qusha Tepe which was a cemetery belonging to the Iron Age was carried out during the first season of excavation in Yeri City. The cemetery has been completely plundered and today just the architectural structure of the graves is remaining. During the stratigraphy of the third season of excavations in Yeri City the layers belonging to the Bronze Age, and the transitional from Bronze Age to the Copper and Stone ages and the layers of the Neolithic epoch were identified.
During the last season of excavation in the plain of Yeri City, some articles such as gold and bronze charms including earrings, tassels, rings, ornamental articles from glass paste, and different kinds of azure and turquoise beads and opals were unearthed.
The 400-hectare historical site of Yeri City is situated near Pirazman village in the vicinity of Meshkin Shahr in the northwestern province of Ardabil. The region consists of three areas: a temple, a fortress, and Qusha Tepe plain. The temple and the fortress belong to the Iron Age, and Qusha Tepe plain dates back to the Neolithic epoch.
