An expedition of the Southern University of Texas explored the Sebilian culture on the Dishna plains.[4] The Ain Khoman tools of Oasis Baharia were identified as similar to the Esnan industry of the Dishna dated to c.12,300 B.P, differing only with respect to bifacial tools.[5] Several sites between Wadi Kubbaniya and the plains contained assemblages also of Esnan industrial production.[6] The Esnan industry, also known as Mesnian, employed a non-levallois technique, productions composed largely of end-scrapers, though also including a much smaller number of arch-backed bladelets and trapezoid.[7]
