Content of review 2, reviewed on May 01, 2020

This is an interesting article that utilizes the integrated isotope stratigraphies (87Sr/86Sr, 13C) and the microfacies analyses of the Aruma Formation, Saudi Arabia to provide a proper age assignment and construct a sequence stratigraphic model liable for global and regional correlations.

The article is well written and well organized. I have found some spelling corrections and made some corrections in the attached PDF file. I would just like to draw your attention to the references that do not correctly match with journal style. Apart from these few comments that do not affect the quality of the paper, I agree with all parts of the article.

Best wishes,
