ORTHOCERAS Meaning and Definition

1. Orthoceras is a genus of extinct marine cephalopods that lived from the Early Ordovician to the Late Triassic period. It belongs to the class Cephalopoda, which includes modern-day squids, octopuses, and nautiluses. The name "Orthoceras" is derived from the Greek words "ortho" meaning straight, and "keras" meaning horn, referring to the long, straight shape of their shell.

   Orthoceras possessed a long, conical shell, composed of calcite, with a series of internal chambers or compartments. The shell had a siphuncle, a tubular structure running through the center of each chamber, which was used for controlling buoyancy. The animal, resembling a modern-day nautilus, occupied the last chamber of the shell, while the previous ones were used for adding gaseous or liquid material to help control its buoyancy and movement in the water.

   These creatures were highly efficient swimmers and predators, equipped with numerous tentacles, a beak-like mouth, and sharp beak for capturing and devouring prey. They had an excellent sense of vision, with large eyes positioned on the sides of their head.

   Orthoceras fossils are relatively abundant and widespread, found in various sedimentary rocks around the world. They provide valuable insights into the ancient marine ecosystem and serve as index fossils for dating rocks of the Early Paleozoic era. Due to their beautiful and distinctive spiral patterns, Orthoceras fossils are highly appreciated by collectors and are often used in jewelry and decorative items.

2. In geol., a genus of straight, tapering, chambered shells-so called from their tapering to a point like a horn; the family is termed.

The term was used to describe the characteristic straight, horn-like shape of the fossilized remains of ancient cephalopods belonging to the orthoceratid family.
