The Story of the World's Favorite Fossil

The video explores the fascinating history of orthoceras, a genus of ancient cephalopods that lived over 450 million years ago. It discusses their discovery, evolutionary significance during the Ordovician era, and their role as predators in ancient seas. The video also explains the fossilization process and why orthoceras fossils are so abundant today, particularly in regions like Sweden and Morocco. Viewers learn about the unique features of orthoceras, such as their long, narrow shells and the siphuncle, which helped them propel through water.
