A small 4,400 - twelvemonth - former town in the Khaybar Oasis of Saudi Arabia suggest that Bronze Age people in this region were dull to urbanise , unlike their contemporaries in Egypt and Mesopotamia , a novel study witness .

archaeologist discovered the web site near the metropolis of Al-‘Ula in the Hejaz neighborhood of western Saudi Arabia and called it " al - Natah . " The colonisation cover about 3.7 acres ( 1.5 hectares ) , " including a central territorial dominion and nearby residential dominion smother by protective wall , " the researchers state in a financial statement .

The residential area had a large amount of clayware and grinding stone , as well as the remains of at least 50 abode that may have been made of earthen materials . The central area had two buildings that may have been used as administrative areas , the team write in the paper . In the western part of the central area , a necropolis was institute . It has large and high circular grave that archaeologists call " stepped tugboat tomb . "

No examples of writing have been find so far at the situation , subject field leading authorGuillaume Charloux , an archeologist at the French National Center for Scientific Research ( CNRS ) , told Live Science in an e-mail . investigator have unearth only a few traces of food grain , but based on discovery at other sites it ’s likely that al - Natah ’s mass grew crops near the site , Charloux order .

The township and its nearby sphere were surrounded by a 9 - naut mi - longsighted ( 14.5 kilometers ) wall , which would haveprovided defense from raidscarried out by nomads , the team wrote in an earlier paper print in theJournal of Archaeological Science : report card .

The township was abandoned sometime between 1500 and 1300 B.C. , but research worker are n’t sure why this happened . " It ’s a apposite inquiry that I ca n’t really serve at the second , " Charloux said , mention that " we have very few cue about the last phase of occupation . "

Slow urbanization

At the metre the town was populate , cities were flourish inMesopotamia , Egyptand the eastern Mediterranean . Research from al - Natah and other web site argue that urbanization on the Arabian Peninsula moved at a dull pace .

" Settlements in northerly Arabia were in a transitional level of urbanisation during the third to 2nd millennium [ B.C. ] , " the investigator said in the statement . They call this phase " gloomy urbanisation , " describing it as a transitional stage between pastoralism , in which nomadic masses follow graze lands for livestock , and complex urban settlements .

" While urbanization began in Mesopotamia and Egypt in the 4th millenniumB.C. , our study lean to show that social complexness increase late in Frederick North - westerly Arabia , " Charloux enjoin , remark that urbanization did n’t start on the peninsula until the second one-half of the third millennium B.C. , when some group on the Arabian peninsula adopt a sedentary lifestyle and started using agriculture on larger scale . multitude in Egypt andMesopotamia adopted sedentary lifestylesin earlier time .

Stone-lined tomb.

compare to the large Bronze Age city in Mesopotamia and Egypt , settlements in Saudi Arabia be given to be smaller . " These were little townspeople connected to networks of monolithic wall surrounding the tumid local oases , " Charloux said .

Juan Manuel Tebes , the managing director of the Center of Studies of Ancient Near Eastern History at the Catholic University of Argentina , praise the enquiry .

" The archaeological project at Khaybar is a most significant study that follows and elaborate the conclusions of excavations and surveys that have been carried out in north - west Saudi Arabia during the last 20 geezerhood , " Tebes , who was not involved in the study , told Live Science in an e-mail .

He note that other projects in the part , such as the Saudi-Arabian - German expedition at the city of Tayma and the Saudi-Arabian - Austrian expedition at Qurayyah , have also provided valuable information about the region ’s archeology . For instance , excavations at Tayma have bring out thousands of year of line and include cadaver that date to when a Babylonian king named Nabonidus ( prevail 556 to 539 B.C. ) lived in the country .

Robert Andrew Carter , a senior archeology pedantic and fieldwork development specialist at Qatar Museums who was not involve in the report , also commend the team ’s work . " We only have a unelaborated understanding of the Bronze Age and the bloodline of urbanism in the [ Hejez sphere of westerly Saudi Arabia ] and this study go a long agency in supply basal data point , and ameliorate our theoretical discernment , " Carter told Live Science in an e-mail .
