And while specimens have been found almost everywhere on the planet, Antarctica is well-known for its rich ammonite fossil sites. Among the most extraordinary ammonite species found in Antarctica is Diplomoceras cylindraceum, which could grow up to 2 meters long and is noted for its paperclip-shaped, uncoiled shell.
Ammonites were shelled cephalopods that died out about 66 million years ago. Fossils of them are found all around the world, sometimes in very large concentrations. The often tightly wound shells of ammonites may be a familiar sight, but how much do you know about the animals that once lived inside?

Ammonites, which evolved about 416 million years ago, were once the most abundant animals of the ancient seas. Scientists have identified more than 10,000 ammonite species, such as Arnioceras semocostatum pictured here, and use their shells to date other fossils. Please be respectful of copyright.
