Is this find identified with Sumer? Same general area. Sounds like in the region where Ur was/is to me.
The pre-Sumerian Ur is known as Ubaid; the Sumerians themselves said they’d come in from the Persian Gulf. This find is older, and not a precursor; from the Neolithic or New Stone Age. The article sez it dates from the dawn of agriculture, but a sample of multirow barley (which is a domesticated form, and requires irrigation) from (if memory serves) somewhere NE of this site, RC dated to 14,000 years ago.
