Orthoceras fossil

Orthoceras (which means ‘straight horn’) are the fossilised remains of a group of cephalopods that existed from 360-470 million years ago. These creatures had a shell that was straight or conical and were the most advanced invertebrates of their time. Orthoceras fossils are relatively common and have a global distribution, occurring in any marine rock, especially limestone. Orthoceras fossil jewellery really inspires the imagination and their crystallized chambers make a bright contrast to the dark black or brown limestone or sedimentary matrix that surrounds the fossil. These fossils, beautifully smoothed and polished in the material they were found in, make attractive jewellery items and a stunning fashion statement.
