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.

Update to range plots - I have now changed the way range data is plotted on species pages, the histograms still show the data from the Neptune database but the nannotax range is now directly compared to it. Also the background image shows the stages using GTS colours (hover mouse over the plot to see stage names).

Hi Is there any Channel about calcareous nannofossils in telegram or other social networks?

Hi, I am new in learning nannoplankton from Geological Research and Development Centre, Geological Agency, Indonesia... Many thanks to all contributor of this website.Thaks,Masykur
Hi, I am doing a little study sort of updating Aubry et al. 2005 on Mesozoic cocco size. To do so, I saw that we can plot coccolith from nannotax with stratigraphic range. But I wonder we can extract those data in .txt? It would save me thousands of copy/paste. Thanks Bap

hi Baptiste If you let me know what you want I can almost certainly send you the data Jeremy

I would like to know if someone is working with calcareous nannofossils from Eastern Equatorial Pacific, my field work is in this area. I found very few publication on Cenozoic calcareous nannofossils for this area. I am wondering if it is worth to make a review paper for this Pacific side and construct a geographic data using ArcGIS.

Hi Emilia It might be worth trying posting that on the coccoliths list server, that may work better for getting general comments. Synthesising an reviewing data almost always proves useful in my experience though so your idea sounds well worth thinking about. Jeremy

hi, thanks for good website.If you have a possibility of sorting all specious of nannofossils based on each stages(age range) for search, it will be more helpfull. Regards.

Hi Fatemeh The main way you can do an age related search is to go to Tools/Prefs & Time Control. There you can set the time interval you are interested in (e.g. Oligocene or Albian or 100 to 102 Ma) and the taxa which fall within that time interval will be highlighted. If you wanted something a bit different to that then feel free to explain a bit more. All the best Jeremy

Hi thanks for your reply,I tried in that way but It didn't work or I need more guide. Regards
Hi. I'm a usual user of Nannotax. I was only wondering if it's goin to be available in the future a sort of "mobile application"of the website in order to make the most of it also on mobile devices.Thanks and good nannopaleontology to anyone ! A.

A few more recent updates:
Farinacci catalog pages are now all available as PDFs with selectable text
Image file names can now be shown below the images (see Tools/Prefs & Time Control)
A lot of extra Mesozoic images have been added

Farinacci catalog update. We have now completed a major update of the Farinacci catalog with additional entries for most taxa described since Anna Farinacci stopped compiling the catalog in 1989 and now there are both PDF and jpeg versions of most pages. The PDF version are better quality but the jpeg versions are quicker to use so we will leave them on the site. There also is more metadata for taxa in the Farinacci catalog.

Adding data from the neptune database For the INA15 meeting in the Philipines we have done a series of further updates, including adding a lot more Mesozoic images. The BIG change though is that we have now added occurrence data from the Neptune database. This provides useful information on the abundance of taxa through time - BUT READ THE NOTES PAGE. From the menu bar - About Nannotax/The Neptune Database

Progress update. In preparation fro the upcoming workshop on living coccoithophores I have just now completed an overhaul of the coverage of extant nannos including adding 1000 more images and a separate module for non-coccolithophres. The non-coccos module is very much a work in progress, so comments and suggestions are welcome.

Regarding to Time scale I have also a comment. The first occurrence of Catinaster coalitus in the Mediterranean is noted at 10,73-10,74 Ma (Hilgen et al., 2003). But, its FO of which defines the base of the NN8 zone, is rare or absent in many Mediterranean sections. Radiometric analyses from the Paratethys (Poland and Eastern Slovakian Basin) placed the period between 11,3-10,9 Ma (Vass, 1999; Ková_ et al., 2001), which is a consequence of more alcaline marine environment, what is not the case for Mediterranean area in that time. Unfortunately this facts are not included in any Time scale. I hope I'll publish soon my work about that.

I'm curious why the datums included in the Gradstein 2012 geologic timescale book seem to be outdated or in conflict with ranges posted on this site, which I rely on heavily as an excellent reference? I post here because, for instance, Top (downhole)O. serratus is listed at NN2 the bottom of its range noted here NN2-NN6.
Jeremy Young

Hi Aaron We have not used GTS2012 for nannofossil ranges (only for age calibrations) so there may well be discrepancies. In this particular case I suspect someone has entered LAD into a database when they should have written FAD. O. serratus definitely occurs from NN2 to NN6 (it may of course have a longer range but there are plenty of records of specimens through that age range).

Hi Jeremy I have been working closely over the Santonian - Turonian section and I am not sure the Millions of year ages match for some taxa in the database?. So you know I have been comparing the database with what I observed, Jackie and various other papers along with Timescale Creator but was not sure what to do about really any suggestions?
Jeremy Young

Hi Steve First thing to note here is that ages are always given as some sort of primary data - e.g. a chronostrat stage or nanno zone then the translation into Ma age.The primary data is stored in the database and the Ma age conversion is done by the program as needed, using a look-up table provided by Jim Ogg, with the age quoted being that of either the top or the bottom of the time interval, as appropriate. E.g. If the primary data is that the LAD is in Late Turonian then the Ma age given is 91.41 which is the age of the top of the Late Turonian, conversely if the FAD is in the Late Turonian then the Ma age given would be 89.77. The ages are all from GTS 2012 so can be looked up by using the range charts (Tools menu). Specific problems might be caused by the primary data being wrong (e.g. the LAD should be Mid Cenomanian not Early Turonian) or possibly by an error in the look-up table. If you have spotted likely glitches do let me know.

Latest innovations - I have made a couple of improvements in the last week or so. First google translate is now enabled so you can read descriptions in almost any language you like, I hope this will especially help students who don't speak english. Second - I have finally got links from the Farinacci page to the main pages. This was a quite an interesting little coding problem and then required some more work on the links themselves. Jeremy

- there is more information on the user guide page http://ina.tmsoc.org/Nannotax3/ntax-userguide.htmlThat should explain what to do.Jeremy"""
