Geodized Spirifer

Recommended Posts

Found this on Sunday while out hunting with the KC gang. I love that you can plainly see the outline of the spirifer and the delicate crystal structure. It looks as though you can see some of the internal body parts/structure of the brach itself! Pennsylvanian, Johnson Co. Kansas

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.

Super cool. I love when this happens to brachiopods. Does anyone know why this occurs? Maybe no sediment infill to the interior of the brach, which allowed room for crystal growth or is this during dewatering and diagenesis?
