Grade: A
Origin: Morocco
Grade: A
Dimensions:
About 40-60mm
Weight:
About 10g
Orthoceras with holes of approximately 20-30mm supplied with waxed cotton cord
Patterns and colors may vary from stone to stone.
Orthoceras lived during the Paleozoic era, from the Ordovician about 470 Ma (million years ago) until the end of the Permian when they became extinct in the great Permian-Triassic extinction about 252 Ma ago.
Orthocerans were cephalopods with univalve shells, like their distant cousins the nautiluses today, but the shell of 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 that connects the chambers of the shell is in an axial position. Nautiloids are quite common with a wide geographic distribution1 and an extraordinary diversity in forms. The large orthocerans were the main predators of the Paleozoic geological era. The lifestyle of these animals remains partly unknown.
