Nannotax - forum
So, the idea here is that we can use the commenting tools to discuss anything about the site or coccolithophores. If discussions get long we can split the page into different topics. If no-one says anything we may quietly remove the page.
However, we will read every comment posted here so feel free to use this for:
- Bug reports and complaints about the site
- Suggestions of things we might do with the site
- Discussing preparation methods, microscopy techniques, etc.
- Publicising meetings or vacancies
- Comments on how you use the site
How to add comments
If you scroll down to the bottom of the page you will find a heading "Add Comment" and a form to fill in. To reply to a comment click the curvedarrow symbol below and to the right of it. The same layout is there on every taxon page. For a bit more advice you can see the guidelines.
You are exactly right. The issue is related to the browser used on my Windows-based laptop. The machine uses Microsoft Edge. It has handled Nannotax fine until very recently, so there must have been an update. My Mac laptop (using a different browser) continues to handle Nannotax perfectly well. Anyway, the issue is definitely browser-related.
Thanks again for your help.
I have just tried the site on a windows computer with Microsoft Edge and it still works ok. I suspect the problem may be something to do with caching - I have recently changed the way some addresses are handled. So, you could try emptying caches/ deleting browsing history.
FYI - The links to the detailed species information (e.g. individual species pages) appears to be broken, as of Dec. 30, 2022.
Happy New Year.
Thanks for reporting that. I think what you encountered was a temporary problem while I was doing some work on the system, and it should be Ok now.
Thank you for the information. I'm still having issues with accessing the pages for individual species. If it's working on your end, then the issue is likely on my end.
I cant't see any problem from my end but it may be an incompatiblity related to your set-up. Have you tested with a different browser or on another computer? If you do find there is a persisitent problem with a specific set-up do let me know as usually there are solutions possible from the developer end. Alterntively if it is being consistently slow in your location then it would be useful to know that as well
I found your site is GREAT! Very well organized and therefore very useful, especially because I was very recently editing a manuscript on nannofossils for Carnets Geol. https://doi.org/10.2110/carnets.2022.2217
I have few suggestions/comments.
1) For instance, in your reference list, it happens that papers by a single author follow multiauthored papers by the same first author (they should precede them)
2) You consider that nobiliary particles are part of the author's family name. There should not: van Hinte should be cited as Hinte and listed in the reference under the letter H
(but another Van Hinte with a first capital letter should be listed under the letter V; de Jong as Jong, under J, not under D; ... d'Orbigny as Orbigny, under O, not under D.
All best wishes,
Thank you for the appreciation and for the link to the paper - Bernard Lambert's work is always interesting to see and I will certainly add that to the bibliography. I had not really noticed the reference sorting problem but it was easy to fix, thank you for pointing it out. Honorific prefixies are more problematic since opinions vary on how to handle them, but maybe it is time to go back and tidy them up.
The Farinacci catalogue lists 3 species under the genus Pharus Wind & Wise. As I understand it, this genus falls within the informal concept of "algae", and its nomenclature is therefore covered by the International Code of Nomenclature for algae, fungi, and plants, current edition 2018. This means that the genus name Pharus Wind & Wise is illegitimate, as it is a later homonym of Pharus P.Browne, a genus of neotropical grasses, name published in 1756. I am trying to get this message to somebody active in nannofossil research so that a valid replacement name can be published.
Dear Keith Edkins
Thank you for your comment. Pharus Wind & Wise 1977 is indeed an alga and so a junior homonym of Pharus Browne 1756. The taxonomy of this group of Late Cretaceous holococcoliths is problematic but there is no other obvious genus for the species so a new name shoudl be propesed. I believe you have been in touch with Dr Jackie Lees and she would be an ideal person to collaborate on this.
Can you give me the correct reference for this site for inclusion in publication. I have had two papers to review which give completely contrasting refences for the sight e.g. different years etc
Hi Kevin - I have put some advice on citations on a page linked from the menu at the top - "About Nannotax/API citation and copyright. BUT there's a complication that the correct format for citing websites is set by the journal and will differ between journals.
Lovely to hear from you, it is always nice to know the website is being used in different ways and you are very welcome to share images from it. If you have any suggestions for how we can make it more useful please do let us know.
all the best
I m Mahani. I hope that you still remember me. I m now no more with Petronas. I am trying to educate the young biostratigrapher in nanno and foram. I share your fossil photos in my Instagram.
There is a very important question - why the stratigraphic scale of the Paleogene on the Nannotax3 site does not correspond to the stratigraphic scale in the GTS-2020 book? What to take as a basis?
Good question - I do indeed need to update the site to use GTS2020. Doing so is a bit of a project though, and I have just not found the time to do it yet. For the most prt though the difference between GTS2020 and 2012 are small in our time interval - the big changes are in the Palaeozoic. Thank you for reminding me though, it is something Ineed to do.
all the best
Superb, very nice information
Hi, are the photos of the nannofossil species on this site raw (pure from a microscope) or have a lot of noise (already processed)?
Thank you in advance.
Hi the images come from many different sources and were taken on different types of microcope. ..but nannofossils are small (only a few microns) so they are difficult to image even with the best equipment.
Hello, Just been through the pictures on the webpage but can't find something that gets me closer to figuring out what this is. Any ideas?
That is a fairly well known undescribed Syracosphaera species - it is on here as
Syracosphaera sp. A.
Those are lovely images, it is ok if I post them on the relevant page. I'll also put you in touch via email with someone who else who has some images and is describing the species.
Thank you, I missed those, sorry! It's fine to post the pictures yes, just for reference this sample was from 50m depth and taken between Madeira and the Gibraltar straights in May 2019
Thank you Tatiana
that is much appreciated - and i will look forward to see more results of your work.
I have an identification quizz for you all. I found this in the subtropical Pacific Ocean (near Tonga volcano ridge) in a sediment trap moored at -170 m. It looks like calcite and was found in a sample with a large amount of coccolithophores (at least 25 different species). I was wondering whether this perfect ice cream cone could be a coccolith or something that you already stumbled upon ? Thanks a lot for your help ! Cheers.
That is definitely not a coccolith but it certainly is nice. I agree it looks calcareous and I suspect it might be the proloculus (first chamber) of a very small foram - it has both a terminal aperture and pores on the shell. There are some microfossil groups on facebok which might help with an identification.
Thanks for your response! I'll try to investigate on the foram side...Cheers
I don't know if this was a mistake. I think the fourth (otherwise of excellent quality) picture placed under Hayesites irregularis (named KCooper-Rucinolithus irregularis.jpg) in the nannotax website probably is more compatible with the description of Hayesites albiensis. The specimen appering in this picture has a marked stellate and regular outline having only six long rays.
yes, you are right, in terms of the species concepts outlined here this specimen clearly ought to be in albiensis, I have transferred the image.
NB If you are commenting on an image it is easiest if you add the comment on the bottom of the taxon page the image is on.
We're looking at samples of freshwater collected for us by school groups, we're actually looking for viruses under TEM but we as hard pellet ( 200K RCF ) after a 6 micron filter we get everything and we're pulling out a lot of what look like coccoliths. I can't find much information on fresh water species but we have structures resembling Palusphaera and others. Are there any resources about fresh water species?
Thanks for posting that image. Those are not coccoliths but non-calcified scales. Actually quite a few different protists use scales to form composite exoskeletons and these are variously formed of resistant organics, silica or calcite (coccoliths). I am not an expert on these groups but I think your images are of Paraphysomonas and if you do a google search on that it should get results. i would like to have more images of these sort of things in the non-coco section, so if you could send me some images that would be appreciated.
thanks! That's really useful information. I'll sort some images out for you - might take a while as we have around a thousand frames to go through. We also have map refs and some basic water quality info for each collection site. Drop me an email and I'll send them as zipped download links. The actual project is here - http://www.warwick.ac.uk/virushunters
Dear Professor Young,
I am working on several strains of the species of genus Pleurochrysis (I found the name has been changed to Chrysotila). These strains were isolated from aquaculture pool and bloomed in shrimp pools. The bloom did harm to the organisms. However, I am not quite sure what the exact name of the species is. Could I email you some of the SEM pictures and please help me to identify the species?
Dear Chengxu Zhou
Thank you for sending those images (I have unblocked the upload of them). I think they are, C. pseudoroscoffensis, but I am not an expert on this group of coccolithophores. You might like to try to contact Ian Probert of Roscoff Marine Lab in France.
Thank you very much for your reply. I will try to contact Dr.Probert.
Dear Dr. Young,
Thank you very much!
