Dear Catarina Cavaleiro,
Thanks for your rebuttal letter which is convincing. One reviewer was quite positive and the other had important remarks, (statistics, comparison with other proxies...). It would be important that the new version of your work will be reviewed one again by this reviewer.
Yours,
Luc Beaufort

Dear Catarina Cavaleiro and coauthor,
I read your responses to reviewers. The corrections you propose are on the right tracks The proposed corrections are very consequent and are positive. Their importance means that the manuscript must be reviewed by the most critical reviewer. I therefore place your manuscript as requiring major revisions.
Yours sincerely,
Luc Beaufort

Dear Catarina Cavaleiro and coauthors,
I am glad to inform you that your manuscript is ready for publication. Three minor technical points have to be fixed before :
1- Line 210 : 'gephirocapsids' should be written 'gephyrocapsids'
2- Fig.6b : left scale title is missing
3- Fig.6d : label 'd' is missing
Yours sincerely,
Luc Beaufort
