“How were they dated’’.
Indeed. A 10,000 year old engraving on a bare rock face and no erosion of the image? That could have been scratched in there when ever.
However if it is indeed that old and this was during the Ice Age Period it would show that at one time giraffes , which is what those images appear to be, were in that part of what is now the Middle East.
Fascinating.
So much for Ford Prefect being involved in creating the Giraffe.
