"These 3 inch polished orthoceras specimens are from the Devonian period of the Paleozoic Era and are close to 400 million years old! Beautifully polished, they show the segmented body and the tube used for propelling the ancient cephalopod through the water. Each specimen is unique. Photo demonstrates style and quality. This is a sample of our inventory. Each piece is different but all are comparable to the ones in the picture."
