Tornoceras was a Devonian cephalopod that thrived in the warm paleozoic seas. It's thought that, due to close association, these squid-like animals were predators of trilobites. Tornoceras from the Widder formation in SW Ontario are more often than not, pyritized. Pyritization occurs due to the high concentration of the mineral in the host rock. Often, the living chambers are preserved in incredible detail.

A large and clean example of this under-appreciated species! Pyrite from SW Ontario is stable and safe, however, will lose lustre over time. Keep out of humid environments for best lasting shine.
