Calymene Trilobite & Brachiopods - Waldron Shale

This is a 2.4" piece of limestone containing a partially exposed Calymene breviceps trilobite, several brachiopods (Stegerzhynchus) and other trilobite parts. It is from the Silurian aged Waldron Shale of Indiana. The fossils have been nicely exposed with air abrasives.
