Diatoms!

Hi all. Here's some recent pics. I'm sketchy on the Coscinodiscus ID.
Thanks

Very nice. I particularly like the last two showing the two different views, I've never seen a side on of Podosira like that.

Hi Frez, nice to see some of your images! I have never seen such a big Thalassiosira nordenkioeldii, and the detail you show is amazing. Concerning your Coscinodiscus, I think it is C. radiatus, at least that's how I see the extant species in dutch marine waters. Typical characteristic of C radiatus: it's flat as a pancake, no stacking necessary, even with oil immersion. I've got an example at http://www.photomacrography.net/forum/v ... 47276ff31b

Best wishes, René

Thank you Jacek and Cactusdave. René, I agree with your ID. It is a relatively flat specimen. I changed the name. Sometimes finding an ID only takes a few minutes and other times it takes hours of searching. It's good to get it right though. Thank you very much. The image below is another I have been searching for to ID.

René, what do you think about changing S. arabica to S. comis Schmidt?

Thanks

Don't know Frez, I do try to stick to the things I come across here (and that's difficult enough aS IT IS ;-)

Good luck, René

That's for sure. I changed the name to S. comis. The advice came from a very reliable source.

Thanks
Frez
