After studying texts at Mari, Georges Dossin traveled to a site he called "Tell Biya" and identified it as Tuttul, ending much speculation as to its location.

Some Early Dynastic I period remains were found below that and the water table was encountered before virgin soil was reached.

[10][11] At the Early Dynastic level on the southern end of Mound E six above ground multichambered rectilinear royal tombs were found.

The tombs had been looted in antiquity, but contained human and animal bones, jewelry, inlaid furniture, and a large array of pottery.

He (the god Dagan) gave to him (Sargon) the Upper Land: Mari, Iarmuti, and Ebla far as the Cedar Forest and the Silver Mountains.".

Tuttul was later mentioned by his Sargon's grandson Naram-Sin of Akkad (c. 2254–2218 BC), as one of the cities whose god was asked for him to become deified.

[23] There was also a temple of the "River-god" at Tuttul, a poorly understood entity which has been suggested as the deified Euphrates, which was recorded as receiving sacrifices.

[25] In a brick inscription from the building of the Shamash temple in Mari he recorded a revolt against his rule that included Tuttul.

"[25] Zimri-Lim, ruler or Mari, son of Yahdun-Lim and contemporary of Hammurabi of the First Babylonian Empire also included Tuttul in his royal tutelary.

Though there is no archaeological evidence at the site, Tuttul is mentioned in late 2nd millennium BC New Kingdom Hittite and Middle Assyrian texts, as the two empires contested for that region.

[27] It appears that during the period, the Late Bronze Age, Tuttul served only as a small cultic center for Dagan.
