Orthoceras is a genus of extinct nautiloid cephalopods that lived during the Middle Ordovician period and was found in the marine limestones of the Baltic States and Sweden. This genus is also known as Orthoceratites, and it is important to note that it is sometimes misspelled as Orthocera, Orthocerus or Orthoceros.

Initially believed to have a global distribution, Orthoceras was commonly used as a wastebasket taxon for several species of conical-shelled nautiloids throughout the Paleozoic and Triassic eras. However, nowadays, Orthoceras sensu stricto refers to O. regulare, found in the Ordovician-aged Baltic Sea limestones of Sweden and nearby areas.

These shells are slender and elongated, with the middle of the body chamber transversely constricted and a subcentral orthochoanitic siphuncle. The surface is adorned with a network of delicate lirae. Michelinoceras includes many other very similar species.

ACTUAL AS SEEN: The image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.
