Project Mini-Calymene

My new project is to clean this small Calymene trilobite found in the Silurian Period Waldron Shale. Since it is so small ( < 2 cm), I am using a dissecting needle.  My cousin advised using the microscope and that has been a great idea.  The needle is too large for removing matrix in the thorax grooves so I need to find a smaller cleaning needle.

I was happy that the trilobite is intact.  The spots where the eyes were are worn away but otherwise the trilobite looks to be in good shape.

After the first prep session that used a needle, toothbrush, water, and a microscope.
