There has been more than four decades since Frank Hole and Kent Flannery conducted a field expedition in central Zagros Mountains located in western Iran, in 1963. From then onward, numerous discoveries and field projects have been done in this region. Some of these findings may contradict the report of the original survey. Although the goal of this article by no means, is to criticize the 1967 report, it sounds unavoidable to incorporate the new discoveries in it. For instance, the author of this article believes that the twelve missing sites in the 1963 survey were found later, hence; new discoveries in case of the presence of Levallois technique in the Zagros Mountains could change our understanding regarding the Middle Paleolithic of Zagros.
