The QCC Posted November 6, 2017 Share Posted November 6, 2017 A few small pieces of matrix were cut from Arkona (Hungry Hollow) slabs obtained from Bob O'Donnell. This is the first thin section from the small pieces of matrix. The small pieces (20mm x 25mm) were mounted on petrographic slides and ground and polished to approximately 50 µ. Photo one shows the matrix before it was mounted on the glass slide. Photo two is the thin section slide made from the small piece at 1.6x mag. Photo three is the object at the bottom of the slide at 10x and full wave plate. Link to comment Share on other sites More sharing options...
Shamalama Posted November 6, 2017 Share Posted November 6, 2017 Great photos! This looks like a section through one of the hardgrounds from the Arkona Fm. I would venture a guess that the "Eye" subject is a Mucrospirifer with the lophophore support as the circle in the middle. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
The QCC Posted November 6, 2017 Author Share Posted November 6, 2017 Thanks for the identification. I am a hobbyist slide maker and micro photographer, not a fossil fanatic. All assistance welcome. Link to comment Share on other sites More sharing options...
