After prospering for 300 million years, the ammonites disappeared when the dinosaurs went extinct 66 million years ago. From shell structure and fossils, it is assumed that the ammonite is closely related to the squid and octopus. The octopus has thrown away its shell in the course of evolution, but it is known to use tools such as coconut shells and bivalves to protect its soft body. Inspired by this evolutionary story, I began a journey of thought experiments to restore the shape of an excavated ammonite shell and arrange an encounter with octopus.
