Flatonia Texas Eocene Diatomite thread

Hello everyone,

here is a pictrue from a very "spiky" Triceratium var.  I found it from K7.

Hello,

I found these two balloons in a dried K7 dusting. They are hollow inside and have a tubular end.

Regards,

Hello,

Here I have an almost complete shell of the small discus  with its five segments. First, I stacked only the upper part, then the entire shell, and converted everything into an anaglyph image.

It's only really interesting in the 3D view, as you can see down through the opening.

Regards,
Michael

Hello diatom friends,
I have done some strew slides of the small fraction of R1 today.
Just to give a kind of impression how this could look like.

A few forms from a sample K2 strew. Stacked brightfield and phase contrast images using Pl Apo 63X/1.40. I like the Auliscus which I had not seen before.

Hello all,

Here's one from the K7 sample. It's a particularly thick 3-dimensional species, so I included a cross-eyed stereo version too. Shot under 450nm blue light for a little better detail (compared to white light).

Dear Steve,
we all waited very impatiently for your images😉. And now it is like we expected, a ,,best of". Thank you for showing us these great details!
Best and happy Eastern

Thanks Anne,

I got rather sidetracked into modifying and testing a cleaning method free of restricted chemicals (no H2O2 either). This Flatonia material is convenient for testing because it breaks up easily without freeze/thaw, but suffers enough "stuck on bits" to make it good to test with. Anyway, I've just about got it right now and will document and share details of the cleaning protocol in the near future.

As my first attempts with small subsamples were less than perfect (too many random annoying stuck on bits at the end), I've cleaned another set of subsamples which came out much better. So now I can concentrate on searching strews and photographing the finds for sharing. Well, mostly...

Cheers
