PONE-D-22-03905Mineralized coleoid cranial cartilage from the Late Triassic Polzberg Konservat-Lagerstätte (Austria)PLOS ONE

Dear Dr. Lukeneder,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process. See "Additional Editor Comments" below.

Please submit your revised manuscript by Apr 18 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Dear authors,

congratulations to this nice piece of research!

It contains a comprehensive suite of methods and I agree with the interpretations and conclusions!

There are only a few aspects I am not happy with, most importantly, I think that the main finding is the interpretation that these structures are indeed cephalic cartilages. Thus, I recommend the following actions:

1. Expand the chapter where you homologize structures (the conclusion is almost longer than your discussion of this aspect).

2. Really discuss homology: relative position, specific quality and evolutionary transitions. It is not that I am not believing you, your discussion just lacks some detail.

3. Do this for the main parts of the cartilage.

4. Add one phrase where you mention this since I think this is one of the main discoveries! I was always wondering what these black blobs were, now we know!

Besides, I marked some style issues. For example, I would not use 'clearly', since this is rhetoric. Also, Fig. 8 is strange, because panel B expands beyond its frame. I marked other small issues in the pdf.

Overall, this shouldn't be too much work.

I look forward to see this published!

Best wishes,

Christian (Klug)

Reviewer #2: Dear authors,

congratulations for this very informative contribution about phragmoteuthid coleoids from the Triassic of Austria. Fossil cranial cartilages of the last common ancestor of octopuses, squids and cuttlefish in 3d preservation is extraordinary.

I find your manuscript well written, your methods are appropriate, your descriptions concise, and your figures of sufficient quality.

I fully agree with your interpretation whereupon your “type A” represents cranial cartilage, but I am not conform with your idea of mega-hooks in the case of “type B” (see my detailed comments annotated in the enclosed pdf). Please note, that both types exhibit similarities & may reflect two different cranial morphologies. If you persist, the presence of mega-hooks in phragmoteuthids allows an array of new palaeontological implications that still need to be addressed.

Apart from this, I think some parts of the manuscript are improvable in terms of a better reading (e.g., sometimes your terminology is inconsistent; more see my detailed comments annotated in the enclosed pdf).

After minor revisions the ms should be considered for publication.

with best wishes

Dirk

Additional Editor Comments:

Dear Petra,

I am now happy with the science but there are still a number of editorial issues. I have uploaded an annotated manuscript, please check it carefully. The main issues are:

- take care of the numerous typos;

- make sure you stick to either American or British spelling, but don't mix them;

- in some of the figures, some letters indicating the panel numbers are really difficult to read; please add a 'background box' or some other means to improve their readability.

- in the reference section, article titles are not capitalized but spelled in the correct way, even if all words start with a capital letter in the original title;

- also in the reference section, please check carefully if the generic names are in italics; I highlighted some, but other may have escaped my attention.

Once these issues are taken care of, I'll be happy to accept your interesting manuscript!

Cheers, Steffen
