About Orthoceras Fossil

Orthoceras means straight horn, and the name fits: this was a squid-like animal living inside a long, straight, cone-shaped shell, swimming warm Paleozoic seas as a hunter. After death, the shell was buried and slowly replaced by calcite, which preserved its chambers as pale, regular partitions. Most polished pieces today come from the Anti-Atlas region of Morocco, where fossil-rich black limestone is quarried near Erfoud, then cut and polished until the shell shows in cross-section.
