The Orthoceras, or “straight horn” is an extinct cephlapod from the Ordovican Period, around 400 million years ago. These straight shelled nautiloids ranged in size from less than a centimeter to more than 14 feet long. It is believed that like current day nautiloids such as squid and octopus, the Orthoceras was a predator, possibly eating little trilobites for a snack.
