Orthoceras extinct nautiloid cephalopod; also known as Orthoceratites. The fossils can be found in all over the world. This specimen was picked up at this years Tucson Gem and Mineral Show and originated in Madagascar.
Orthoceras was an ancient sea animal that lived more than 400 million years ago. The name means straight horn, referring to the characteristic long, straight, conical shell. The preserved shell is all that remains of this ancestor of our modern-day squid.
All the living relatives of these nautiloid, squid, octopus, cuttlefish, and nautilus are predators, and we can assume that Orthoceras was also a hunter of the Paleozoic seas, possibly having trilobites for breakfast!
