  • Orthocerans lived during the Paleozoic era, from the Ordovician about 470 Ma (million years ago) until the end of the Permian when they disappeared during the great Permian-Triassic extinction about 252 Ma.
    Orthocerans were cephalopods with univalve shells, like their distant cousins ​​the nautiluses are today, but the shell of the orthocerans was straight, hence their name. The size of the species varies from a few centimeters to eleven meters in length for the largest members of this family. Like all nautiloids (and unlike ammonoids) the siphon which connects the compartments of the shell is in an axial position. Nautiloids are quite common with a wide geographic distribution1 and extraordinary diversity in shapes. Large orthocerans were the main predators of the Paleozoic geological era. The lifestyle of these animals remains partly unknown.
