[3] Additional work was done at the site in 1937 by Erich Schmidt leading the Persepolis Expedition of the Oriental Institute of the University of Chicago.

[4][5] Some limited work, a single trench, was done at Tall-i Bakun by a team from the Tokyo University led by Namio Egami and Seiichi Masuda in 1956.

[6][7] The most recent excavations, 3 small trenches, were by a joint team of the Oriental Institute and the Iranian Cultural Heritage and Tourism Organization in 2004.

Layer III was the best preserved and shows a settlement in which the residential buildings were built close together with no roads or paths.

[10] The wealth and variety of material items at Bakun and the evidence of large workshop areas point to the existence of local industry and connection/trade with distant regions such as the Persian Gulf, the central plateau, Kerman, and northeastern Iran whence goods like shells, copper, steatite, lapis, and turquoise were procured.

[11] In the late fifth and early fourth millennia BC, Bakun A settlements were at once manufacturing sites and centres for the administration of production and trade.

Their painted pottery featured some unusual specific motifs, such as large-horned mountain sheep and goats, that were rare or unique elsewhere.
