Jerf el Ahmar is a Prepottery Neolithic site (specifically PPNA), located on the Euphrates River of north central Syria. The site is located within 40 km of a number of PPN sites including Mureybit, Dja'de and Göbekli Tepe.

It was occupied during the entire Prepottery Neolithic A period, between ~11500-10500 cal BP, and it is remarkable for a number of grinding stones called querns, which were used to grind wild barley several centuries before its domestication.
One remarkable thing about Jerf el Ahmar, to me anyway, is the fact that I was able to write and publish it five days after I broke my left arm, only because I bought a piece of software called Dragon NaturallySpeaking. If only I could pronounce Jerf el Ahmar the same way every time, it would be far more useful, but not nearly as funny.

There seems to be so much discovery in Anatolia these days. Dating of many of these sites goes far back in time to around 10-12,000 BCE.
Is it possible that all this discovery of previously unknown technology and advanced architecture, such as found at Gobekli Tepe, might be indicative of a civilization that, instead of being on the rise, was actually in decline? Which also suggests the possibility that there may be even more advanced sites yet to be found? Possibly ones not in Anatolia?
Gobekli Tepe was unknown before 1998 and there are more sites yet to be excavated including 90% remaining of Gobekli Tepe.
I had that software at one time. I had to spend too much time on corrections, so I had to content myself with two-fingered typing.
