Drowned Antediluvians: Archaeological and Mythological Imprints of the Persian Gulf Marine Transgression
The marine incursion of the Persian Gulf basin during the early-to-mid Holocene represents one of the most transformative paleogeographic disruptions experienced by early human populations in Southwest Asia. As retreating continental glaciers triggered rapid sea-level rise between 12,000 and 6,000 years before present, seawater breached the Strait of Hormuz. The rising ocean suddenly submerged over 100,000 square kilometers of a fertile, spring-fed valley floor drained by the combined flows of the ancestral Tigris, Euphrates, Karun, and Wadi Batin river networks. This submerged biome, frequently referred to by researchers as the "Gulf Oasis" had served as a demographic refuge, hunting ground, and foraging zone for tens of thousands of years. The irreversible loss of this landmass did not erase human activity; rather, it forced regional populations outward toward the newly formed coastal margins and the deltaic plains of Mesopotamia. This mass displacement catalyzed an extraor...
