I recently learned that some of my geodes are actually fossils. I've been looking at a lot of pictures and this appears to be a crinoid to me but it is large. The ruler is blurry but it's 12 inches. Any help in understanding the difference between a geode rock and a geodized fossil would be fabulous.

This does look like a geodized crinoid calyx, to me.
Unfortunately, I don't know much about the processes involved in their formation.
