None of the following predynastic antediluvian rulers have been verified as historical by archaeological excavations, epigraphical inscriptions or otherwise. While there is no evidence they ever reigned as such, the Sumerians purported them to have lived in the mythical era before the great deluge. Some modern scholars believe the Sumerian deluge story corresponds to localized river flooding at Shuruppak (modern Tell Fara, Iraq) and various other cities as far north as Kish, as revealed by a layer of riverine sediments, radiocarbon dated to c. 2900 BC, which interrupt the continuity of settlement. Polychrome pottery from the Jemdet Nasr period (c. 3000–2900 BC) was discovered immediately below this Shuruppak flood stratum. The antediluvian reigns were measured in Sumerian numerical units known as "sars" (units of 3,600), "ners" (units of 600), and "sosses" (units of 60). Attempts have been made to map these numbers into more reasonable regnal lengths. This was a dynasty from Elam.
