Orthoceras were marine animals that lived somewhere between 200 and 400 million years ago. They are an ancestor to the squid. A mass extinction event happened at some point and many of them died in a shallow water area that is now Morroco. Orthoceras Not only swam but they also crawled along the ocean floor. Their shells fell to the ocean floor when they died. After years of sediment covering them they fossilized into stone.

In order to swim Orthoceras would fill their chambers, (septas)with air, then squirt it out to propel themselves through the water, like a jet!
