Specimen: Orthoceras

Type: Nautiloid Cephalopod

Age: Devonian (~400 million years ago)

Location: Morocco

Orthoceras, meaning “Straight Horn,” is an extinct genus of nautiloid cephalopods that lived over 400 million years ago during the Devonian period. These fascinating marine creatures were early relatives of modern-day squid, octopuses, and cuttlefish. They inhabited the shallow seas and used jet propulsion by expelling water to escape predators—just like their modern descendants.

This fossil preserves the distinctive straight conical shell, which was divided internally by chambers. As the animal grew, it would seal off older chambers with septa and create new ones. A tube called the siphuncle ran through the length of the shell and helped regulate buoyancy by managing gas and fluid levels in the chambers—an ingenious prehistoric adaptation.

Orthoceras fossils are frequently found in the fossil-rich limestone beds of the Atlas Mountains in Morocco. They are popular among collectors and educators for their sleek, elegant form and the insight they provide into early marine life.

Ordovician Information

The Ordovician Period (485–443 million years ago) was a time of marine expansion and biodiversity growth, following the Cambrian Explosion. Warm, shallow seas covered much of the continents, supporting trilobites, brachiopods, corals, and the first true reefs. Jawless fish (early vertebrates) diversified, and the first sea scorpions (eurypterids) became dominant predators. On land, the first primitive plants (moss-like bryophytes) began colonizing damp environments. The climate was initially warm, but by the late Ordovician, a major ice age caused a drastic drop in sea levels, triggering the Ordovician-Silurian mass extinction, which wiped out nearly 85% of marine species. Despite this, the period laid the foundation for the rise of more complex ecosystems in the Silurian.
