The QCC Posted July 22, 2015 Share Posted July 22, 2015 The linked photos are of a further polished thin section of a Turritella fossil.Photo 1 is the original section that was a bit thick.22/index.html]Photo 2 is the same section ground down and polished to 100 microns.Photo 3 is the section as viewed with a polarizing microscope and crossed polars. With crossed polars many small birefringent crystals show up inside the fossil. The remaining photos are close-ups of the crystals.

Auspex Posted July 22, 2015 Share Posted July 22, 2015 ...This is a re-post from my previous thread. It always goes back to the previos post.. You should add new posts to your original topic; they 'keep going' there because I move them there for continuity.

The QCC Posted July 23, 2015 Author Share Posted July 23, 2015 I intended the post as a separate topic to differentiate it from the original preliminary slides. The subject natter is different. Link to comment Share on other sites More sharing options...

Wrangellian Posted July 23, 2015 Share Posted July 23, 2015 Interesting.. are those roundish things biological inclusions inside the whorls? btw I'd like to see an enlargement of the description in your 1st post but you have precluded that with your link.

The QCC Posted July 23, 2015 Author Share Posted July 23, 2015 I apologize for my lack of knowledge about the fossil. I use thin sections of minerals and fossils to make gallery prints. The forum was suggested to me as a place to show the fossil thin sections. My apologies. This is the card that came with the fossil specimen.

Blastoid Posted October 28, 2015 Share Posted October 28, 2015 I'd suggest the oval items are ostracods, abundant little fellows, exquisitely ornamented! Link to comment Share on other sites More sharing options...
