Orthoceras
Orthoceras or straight horn is a genus of extinct nautiloid cephalopod. This genus is sometimes called Orthoceratites. Orthoceras fossils are common and have a global distribution, occurring in any marine rock, especially limestones.
Orthoceras fossil jewellery is more than 400 million years old and is the earliest recognizable animals. They are considered as the ancestors of the modern day squid family. These are considered as the most intelligent form of ocean life even though they were among the earliest form of ocean life.
The size ranges from a few inches to over six feet in length. They have the ability to swim and crawl on the ocean floor. They have the ability to fill their chambers with air and were able to float through seas.
As they died, the shells got accumulated on the ocean floor. These shells got covered by sediments and with the passage of time they got transferred into stone.
These stones when polished gave it a gem like quality making it look more beautiful than ever. These specimens are found in the Morocco’s Atlas Mountains.
