Orthoceras are prehistoric fossil cephalopods (head-footed creatures) related to squid and octopus. Orthoceras means Straight Horn. These ancient mollusks had long, straight shells divided into chambers connected by a narrow tube. The chambers regulated buoyancy by exchanging gases and fluids and the animal lived in the largest chamber. These creatures lived as long as 400 million years ago.
Some people say orthoceras have metaphysical features in that these fossils connect to past spirits and support future success in life!
