The photos presented here are thin sections of a single chamber of an Ammonite. I recently obtained some broken fossil pieces from "Rocks and Gems Canada " for the purpose of slicing them and making thin sections for viewing through a microscope. The first samples are from a Chambered Ammonite. The area of interest is the filling in the chambers. If I am lucky there will be crystal formation, but most of the time it is just fill. This is a web presentation of the photos below The first two photos are the whole Ammonite as I received it. Photo one is a camera snapshot. Photo two is a stereo microscope composite of the Ammonite. The following photos are 1) Polarized light, 2) Polarized light with a Dark Field filter in place. Photos three and four are a single cell of the Ammonite showing what looks like crystal formations. Photos five and six a 4mm segment of the chamber edge. Photos seven and eight show a 1mm segment of a chamber edge.
