Shahdad (archaeological site)

Two other sites on the Shahdad Plain, Tepe Dehno and Tepe East Dehno, have also been excavated.

Archaeology

The site was first noticed due to erosion revealing graves. It was excavated from 1669 until 1974 by a team led by Ali Hakemi of the Archaeological Service of Iran. One main 100 meters by 50 meters trench (Trench A) and five smaller trenches were opened. This work focused on the graveyard (made up of Cemetery A and Cemetery B), clearing 383 graves, one a chamber tomb with painted walls. Finds, in the cemeteries, included a number of near life sized painted clay statues and over 200 chlorite (soapstone) objects as well as 348 potter's marks on vessels. One important find was the "Standard of Shahdad", a square metal plague. Though a number of cylinder seals ("silver and stone with human, vegetal and animal motifs") and stamp seals were found there were no actual clay sealings at the site. A grave (Grave 30), mudbrick and oriented east/west, excavated from Cemetery A produced a vessel containing "white cosmetic preparation" having a radiocarbon date (calibration method - INTCAL20) of 2923–2667 BC. This is in a portion of the calibration curve considered "unfavorable". Other grave goods included copper/bronze vessels and a copper/bronze pin. One of the jars in the gave had a short (6 signs) possible Linear Elamite inscription. A similar sample in Grave 338, also mudbrick and oriented east/west, produced a more reasonable radiocarbon date of 2500–2300 BC (INTCAL20). Grave goods included a necklace of lapis lazuli, agate, white stone, and copper beads. Metal finds included 10 axes with chased designs, and long pins with geometric designs.

A brief surface survey was conducted in 1977. During the survey a 300 foot by 300 foot hill covered with copper smelting debris. Copper being produced contained a small amount of arsenic to strengthen it. A group of 5 mudbrick buildings (site D) was identified in this survey and excavated by A. Hakemi and M.E. Bayani in 1978. It was considered by the excavators to be a metallurgical workshop that had been destroyed in a catastrophic flood. Elaborate ovens found in them were deemed copper-processing furnaces by the excavators. A much later analysis indicated those ovens were actually domestic fireplaces.

Excavations were conducted by Mir Abedin Kaboli in four seasons from 1991 until 1995. Work focused on residential areas as well as a "Jewelry area" with "agate and carnelian flakes dumps, with hundreds of unfinished bead and flint drill-heads". A 1970 Corona satellite image taken in 1970 and a 1993 aerial photograph were used to determine the extent and delineation of the site.

In January 2009 dark green-grey chlorite cylindrical vessel (15.5 centimeters long and 3.6 centimeters wide) dated to the middle of the 3rd millennium BC was found on the surface at the site. The vessel had traces of a lead carbonate based cosmetic.

In 2016 a team of archaeologists with a topographer, led by Nasir Eskandari, did a 2 week walking surface survey of the site which produced a new high resolution topographic map. Thirty test trenches were excavated on the peripheries of areas identified in the surface survey. Results indicated that the 170 hectare occupation area was actually made up of 18 settled areas separated by unsettled spaces forming a distributed occupation.
