Orthoceras Pendant rockinaboxmanhattan 16-18": The top chain measuresOrthoceras was an Ordovician cephalopod with a calcium carbonate shell which provided excellent physical protection against their natural predators. This necklace is a fossilized shell from this animal that has been preserved in great detail. You can even see the individual chambers the nautiloid had in its shell. Each pendant comes with a fine sterling silver backing and an 18 inch chain of the same material.
