Silurian Fossil Trilobite & Crinoid Waldron shale Calymene and Periechocrinus

Description

Hello!
Today I'm offering one of the best Waldron pieces I've had the honor of holding. This piece is a Calymene breviceps with an associated Periechocrinus whitfieldi from the Waldron shale of Shelby county Indiana. The Calymene has excellent color and and is well inflated. Both of the free cheeks are firmly in place. The pygidium is missing but the overall quality of the trilobite is stellar. The Periechocrinus is half missing but is exceptionally large and even has some of the trgmen in tact. The trilobite is a little over an inch long.
