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.
These goniatite come from a clay-like bench where they weather out. Mostly juveniles and micro fauna are found here.

Each purchase will be for a random (complete) goniatite between 4-6mm wide. Postage is included in the price. At this time, we're only offering these to Canada and the contiguous US. These are sent out as letter mail so please allow for extended delivery times. No tracking is offered unless by request and at extra expense.
Pyrite from SW Ontario is stable and safe, however, will lose lustre over time. Keep out of humid environments for best lasting shine.
