Unusual Orthoceras Fossil oval cab - this would have been cut from a huge specimen. Mexican material.

Orthoceras was an animal, not unlike an ammonite, but most often with a long, straight shell. (This is a very simplistic description, sorry) The central patterns in the cab are formed from the fossilised central siphon system, which aided propulsion in the water, The rib like stripes are from the little chambers which could be filled or emptied with gas/water to aid buoyancy and swimming.

The large cab is mainly grey in colour and is polished on the top. The back is smooth, but not highly polished.
