I knocked a few chunks off of a large block of Landscape Limestone, ground them down to 80 microns on a glass slide.
Most of the rocks  I have  collected locally are rather uninteresting as thin sections. I was very surprised to see what I believe to be a lot of micro fossils on two of the slides.
I checked my fossil reference guide and I can identify Crinoid stems, Shells and maybe a leaf.
I assume all those rectangular things are Crinoids an their side.
The average size of the objects is 200 microns. The larges being what I believe are shells at 1,59 mm.

Comments welcome on my identification skills.
Photo 1 is the source of the chunks of rock.

Photo 2 is slide number 3 taken through a Canon Rebel XS (1000D) camera mounted on a Labomed LB 592 polarizing microscope.

I have no idea on your identification. But, I will commend you on your photography. Superb!!!! Photos 2 & 5 are my favorite..........

They could easily be used as wall hanging art.

 

Cheers,

That is some buzzy rock there. All sorts of neet fossils in it.

I can not help with the id'd either.

But thanks for showing this.

Thanks.
I thought Photo 1 was a real block buster.

Crinoids aren’t really identifiable any more than ‘crinoid’ by segments. I doubt there being a leaf, there my be some graptolites though. Very nice job with the photography, the pictures are beautiful!

I thought this looked like a fern leaf ???

Cross section of (maybe) a bryozoan. But not a leaf (or fragment of a leaf.).

You don't mention the magnification you are using, but based on size ("average size is 200μm"), I would wager that most of what you have pictured there are actually diatoms ('microalgae') that are the primary producers in practically every aquatic ecosystem.  The bilateral symmetry of most of the organisms in your pictures sort of gives them away.

 

Great pictures, by the way!
