Micros Id Help

[Bullsnake]

At an exposure of what I believe is Farley limestone in the Wyandotte fm. of the Kansas City group, I found some thin pieces of Osagia laden limestone to examine with the microscope.

Although the Osagia itself is rather plain looking, there are alot of little pieces of recognizable items within, such as brachiopods, crinoids, and bryozoans.

First, the site. The thin ledge can be seen jutting out from the eroded hillside, and scattered pieces are lying below:

This is the piece I've examined so far:

And a little closer:

Some of the recognizables:

Five sided crinoid columnal (~3mm):

Gastropod (1mm+):

Very cool! What setup are you using to take the pictures?

[Bullsnake]

Possibly a brachiopod spine, and piece of shell with spines broken off:

Crinoid columnals and holdfast(?):

Now, the unknowns:

~3mm wide:

~1mm

Appears to be the same thing as previous picture- ~1mm:

I apologize if you have trouble finding the items. I meant to edit the pics to point them out, and will if necessary.

Thank you

Thank you!

Amscope at 20X, and just my point-and-shoot camera.

bottom 2 unknowns are both ostracods,( Kegelites or Polytilites ??); top unknown is anyone's guess ( fish otolith maybe?); the ostracods should be common enough in loose,sieved material to pick out & mount on a slide. Perhaps someone with more knowledge of the microfauna can weigh in.

How did I miss this thread?....

The little perforated ostracods are really cool. I stumbled across one in my stuff just the other day:
