We describe the ecological settings of the sites and
their stone tool assemblages.
It remains unclear what hominin species was responsible for the manufacture of the earlier and later
stone tool assemblages from Jubbah, and it is entirely possible that more than one species was involved.
The Jubbah
stone tool assemblages have their own suite of technological characters, but have types reminiscent of both African Middle Stone Age and Levantine Middle Palaeolithic industries.
The character of some of these horizons may not meet the traditional criteria used by some archaeologists to define valid early sites, such as spatially continuous and multiple activity areas with numerous features, artifact clusters, and diagnostic bifacial
stone tool assemblages [6,26,27].
