Extinct cephalopods very similar in structure to the ammonites. They are ammonoids that lived in the sea with a chambered shell for bouyancy. They can be found around the world but most commercial ones are from Morocco.

Small polished 'buttons' each with a Goniatite fossil, the polish is on the upper surface only. Some good detail of the internal structures filled mainly with calcite. They come from Morocco and date to the Devonian period. They measure around 30-40mm each and you will receive one of the pieces shown or similar. These are all unrepaired, any lines running through them are natural from movement of the rock over millenia.
