Nannotax Enabling nannofossil research

this raises plenty of issues
1. Commenting on 'missing taxa'. This is potentialy a realy valuable funtion of Nannotax, i.e.to get us discussing the less universally understood species concepts. I think it is best done t the place where the taxon is missing from - (so I have copied the comment to the D.musicus page).
2. Posting images - as you found out drag & drop works from external websites, which makes for a great way to rapidly discuss taxa. For a more permanent upload, or for image which are not on an external website use Add Image to put the image in a gallery then drag and drop from there. I've reposted theimage to the Disocaster gallery.
3. Morphotypes and species - if all species were nice and discrete then  biostrat would be  boringly easy. They aren't: we know from modern assemblages than biologically separate species can produce very similar coccoliths, and biostrat experience tells us that some arbitrary distinctions are useful. The problem is to keep track of the concepts people are using when things get arbitrary, which is why we have the site.
4. musicus vs sanmiguelensis - what is the difference in size and range; (and is there a reason for applying the name sanmiguelensis to the smaller form)?
