Bullsnake Posted April 21, 2013 Share Posted April 21, 2013 (edited) 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+): Continued...

jualhadun87 Posted April 21, 2013 Share Posted April 21, 2013 Very cool! What setup are you using to take the pictures? Link to comment Share on other sites More sharing options...
Bullsnake Posted April 21, 2013 Author Share Posted April 21, 2013 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 Steve Link to comment Share on other sites More sharing options...

ted coulianos Posted April 21, 2013 Share Posted April 21, 2013 Possibly a brachiopod spine, and piece of shell with spines broken off: 038.JPG 007 (2).JPG Crinoid columnals and holdfast(?): 013 (2).JPG 011.JPG Now, the unknowns: ~3mm wide: Unknown 3mm wide.JPG ~1mm Unknown-- app. 1mm.JPG Appears to be the same thing as previous picture- ~1mm: Unknown- app.1mm.JPG 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 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. 1 Link to comment Share on other sites More sharing options...

Missourian Posted May 1, 2013 Share Posted May 1, 2013 How did I miss this thread?.... The little perforated ostracods are really cool. I stumbled across one in my stuff just the other day: Context is critical. Link to comment Share on other sites More sharing options...
