The authors have provided a very interesting article into this well-known site, which has undergone numerous different analyses by a multitude of authors. The conclusions reached provide useful new insights and clear up the ambiguity of some of the statements made by previous authors that have studied this area. The analysis is well executed and the evidence presented supports the longevity of the rock art tradition at the Jubbah oasis. This study is certain to allow for a greater understanding of Saudi Arabian rock art and provide useful insights into the Neolithic and Bronze Age rock art traditions. Some points that would be useful for the authors to address include,
Within the article there is mention of the variability in the hardness of the bedrock, but no Moh sale is given. Also, there is little evidence that I am aware of for sandstone having a variable hardness, unless a conglomerate, which from the picture it is not. Thus I would refrain from variable hardness and relate this to variable weathering regimes, which I believe was found to be the case in Shuwaymis (Guagnin et al. 2015). I would also draw your attention to the article Bedarnik, R. G. and Khan, M. 2005. Scientific Studies of Saudi Arabian Rock Art. Rock Art Research 22.1: 49-81.

Note, sand stone, should be written sandstone.

The association of the ‘voluptuous female figures and bird headed figures’ with the Epipalaeolithic, based on a preliminary survey, their proximity to a nearby Epipalaeolithic site and two nearby isolated lithics is difficult to accept. While the superimposition of equids may possibly indicate an earlier phase, I would be wary of dating these to the Epipalaeolithic, as it is strange that this is the only juncture where there is a perceptible break in the rock art tradition, even if you do want to take into account the symbolism of bird wing remains mentioned.

This article would benefit from mentioning how the rock art was pecked, especially with regards the historical rock art which could have been done using metal implements. This may also allow the authors to move away from the use of terms such as ‘slightly fresher looking engravings’.
