A small piece of fossil matrix from Arkona


The QCC

Recommended Posts

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.

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.

Thanks for the identification.
I am a hobbyist slide maker and micro photographer, not a fossil fanatic.
All assistance welcome.
