Goytepe archaeological complex

Goytepe () is a neolithic archaeological complex in Azerbaijan. Goytepe is affiliated with the Shomutepe culture and it is the largest settlement of the early period of Neolithic era in the South Caucasus.
Geographical location.
Goytepe is located in Ganja-Gazakh region of Azerbaijan, 10 km east of Tovuz city, 2 km from the village of Aşağı Quşçu, on the right bank along the middle reaches of Kura river, western terrace of the Zayam valley. The dune of Goytepe covers more than 2 ha, an altitude of 420 m and a diameter of nearly 145 m. 
History.
Goytepe approximately dates back to the 6th millennium cal. BC. is one of the largest settlement sites of the Shomutepe culture. Goytepe started to be investigated thoroughly in 2006, after 4 decades of its initial documentation by archaeologist Ideal Narimanov. An Azerbaijani-French joint mission conducted this investigation in 2006. A topographic map of the mound was made and a few samples of charcoal were taken for determining the age of the site. 
In 2008, the experts from the Institute of Archaeology and Ethnography of Azerbaijan headed by Farhad Guliyev, and the Japanese archaeologists from the University of Tokyo led by Yoshihiro Nishiaki explored this site more extensively in 2009. 
The presentation of the archaeological complex was held at Tokyo University in 2009, at the College-de-France educational institution in Paris and at the British Museum in London in 2010, as well as, at the Archaeology Institute of the Russian Academy of Sciences and at the National History Museum of Georgia in 2011. 
President of Azerbaijan Ilham Aliyev signed an order dated April 18, 2012 on creation of “Goytepe Archaeology Park” for the purpose of thorough study of this monument. 
On April 18, 2012, according to the order of the President of Azerbaijan Ilham Aliyev, Goytepe Archaeological Park was established. 300,000 AZN from the Reserve Fund of the President of Azerbaijan was allocated to the National Academy of Sciences of Azerbaijan for the establishment of the Archaeological Park. 
Stratigraphy and dating.
The area of 300 sq.m. with a depth of 3-4 meters in Goytepe was studied after it was cleared from soil. The excavation area was divided into squares (numbered with numerical numbers – 1, 2, 3 ...) using a 10x10 grid system from the datum point to the north and to the east (labelled by letters – A, B, C ...). In order to ease stratigraphic reading, each square was then divided into 2 parts – west (I) and east (II). 4 squares on top of the mound (1A, 2A, 1B and 2B) were investigated by the Azerbaijani experts, whilst a sub-square (4BII) at the northern part of the hill was excavated by Japanese mission. Moreover, stratigraphy of all the squares primarily conducted by the Japanese experts. The investigation of 1A, 2A, 1B and 2B squares in addition to 4BII sub-square approached a depth of presumably 3 m. 
Since 2008, eight radiocarbon C14 analyses (in French and Japanese labs) of coal residues taken from different squares of the excavation area have been carried out. Four of these analyses belonged to the top layers of the site. 2 group of ages were provided, each belonged to different squares, 5450-5350 cal. BC to squares 1A/B, 2A/B, and 5600-5500 cal. BC to 4BII. The other four analyses cover mainly the cultural layer at the 150-175 cm depth. 
Architecture.
11 m-thick Neolithic cultural sequence recovered in Goytepe consists of 14 architectural levels characterized by mudbrick houses in circular shape linked by curvilinear walls. Building techniques and distribution sequence of architectural remainders found from different levels were mainly similar to each other. Plano-convex-shaped mud bricks with straw temper measuring 40-60 x 20 x 8-10 cm made from yellow or brown clay were used as a building material. These constructions including the ones made of 15 rows of mud bricks with a height of 1.5 m. were considered well-preserved. 
2 types of circular constructions have been discovered at it was in Shomutepe: large and small. The diameter of large circular constructions reached 3.5 m, while the smaller ones had a diameter up to 2 m. The smaller circular constructions used to generally connect with wing walls, although the larger ones were preferred to be mainly independent or not entirely enclosed. There were also revealed other structures such as ovens and bins. After examinations of these structures, it was affirmed that these units were built one by one in a sequential manner with a specific distribution pattern. The settlement featured circular or oval unit with a diameter of 7-8 m, including a number of round-shaped constructions connected with wing walls to surround a courtyard. There was a break on the enclosure wall for each unit which are assumed to be used as the entrance to the yard.
Experts revealed clay bins and ovens/hearths mainly in the courtyard of the settlement close to the wing walls or circular constructions in the archaeological site. The bins with a diameter of 50-60 cm had a round or oval form with a height of 50 cm. The bottom of the bins was dug nearly 10-15 cm into the ground. During the excavations some of them discovered empty, while others were found with different tools and materials showing that they also had a storage function. The ovens with a diameter around 60-70 cm had also a round or oval shape, nevertheless, their bottoms were covered with river cobbles and enclosed by a clay rim. 
In Square 2B, there was also discovered a building in a rectangular form of 4x2.5 m. with a separating wall located quite far away from the circular buildings and assumed that it had been used for a different purpose.
Material Remains.
Ceramic, basalt and obsidian, bone-based labour instruments (awls, needles, axes and hammers), pottery specimens, plant and animal remnants were found from the Neolithic cultural sequence. 
Tools and other objects were infrequently found in the interior parts of smaller circular constructions. In contrast, larger circular constructions and courtyard featured significant number of objects. Several practical tools, including large obsidian blades and large bone instruments were discovered here. 1525 pieces of ceramics were found during the research. 
Pottery.
Pottery samples were found at all layers. Vertical and incurved jars were mostly used, followed by bowls, small vessels without handles and deep bowls. Decorated pottery was hardly found; a few samples of them have simple relief decoration with some circles and oval knobs and wavy lines, while others which were revealed from the upper levels have a monochrome decoration around the neck. Mineral and plant tempered pottery were also found here; whereas, minerals, such as basalt and obsidian were generally used in plan-tempered pottery. Mineral-tempered pottery were found in less quantity from the upper layers.
The use of mineral-temper in pottery is similar to the Shomutepe culture.
Stone artefacts.
More than 5000 lithic artefacts found in this site have been investigated. Almost 70% of them were made of obsidian. Obsidian was mainly used for blade and blade-tools production.
Obsidian artefacts were revealed as a stratified obsidian artefact assemblage (10 levels, 901 pieces) (8) and it is considered that obsidian was extracted from the Lesser Caucasus sources.
Retouched blades and flakes were widely spread among the retouched tool collection. Other predominant tools were burins and splintered pieces which comprised nearly 30% of the whole retouched tools collection. (3) There have also been found denticules, sickle elements, notches and transverse arrowheads.
Non-obsidian raw materials constituted locally available flint, tuff, andesite and mudstone. Flint tools were mainly made on ad-hoc flakes. They featured several glossed blades, which presented the glossed part distributed diagonally to the edge.
There were also found ground stone tools that are considered to be common in this site. Ground slabs, mortars, pounding stones and hand stones were among them. These tools were used for food preparation, as well as, for pigment preparation. 
Other tools.
According to the excavations, it is also assumed that habitats of this site made bone and antler tools, as there were discovered a few samples. Short pointed awl, spatulas and knives are considered to be most common tools among this type. Axes, hammers, picks, and hoes were among the less common ones. Polished axe made of green stone, antler hammer with a smooth surface, wavy grooves and notches were discovered from this site.
Polished axes, smooth surface hammers have similarities with the samples of Shomutepe culture.
Plant and animal remains.
Domesticated plants, mainly wheat and barley were identified in the excavations. Wheat and barley samples found in Goytepe were beaten, charred and blended. Naked barley and free-threshing wheat are specific to Goytepe because these crops have been found rarely in the Neolithic sites of the Middle East such as in Syria and Turkey.
Remains of domesticated goats, sheep and cattle were also found here.
