Fossil Orthoceras & Trilobite Pendant - Sterling Silver

This is a unique, sterling silver pendant featuring real fossils of Orthoceras from Morocco and a trilobite (Elrathia kingii) from the Wheeler Shale of Utah.

Elrathia kingii is a species of trilobite that lived during the Cambrian period approximately 505 million years ago. Their fossils collected in vast numbers from the Wheeler Shale near Delta, UT. Trilobites were hard-shelled, segmented arthropods which dominated earths oceans for several hundred million years before going extinct at the end of the Permian period.

The fossils commonly known as Orthoceras are extinct "straight" cephalopods that lived during the Upper Devonian period around 370 million years ago. Like other cephalopods, they lived inside of their shells, had tentacles they could use to grab food, and used jet propulsion, squirting water to move. The rock containing them is quarried from the Atlas Mountains of Morocco and frequently polished to reveal the fossils and make decorative items with them.

While Orthoceras is the common name for these cephalopods, there are actually several different genera, including Michelinoceras and Arionoceras, found in association. However, unless you are one of the world's leading experts on fossil cephalopods, you probably won't be able to tell them apart.
