Looks to me like you may have poop on your hands. A third of the way up from the bottom looks like pieces of bone. But I may also have egg on my face. Jim

Very cool! We called that pisolite or oolite in Commiefornia. Pisolite was if the orby stuff was larger, oolite if smaller. I know they are biogenic in formation but probably the little concretions form around nuclei that were originally several types of micro organisms. That iron sure gives your example a pretty color. The western stuff is pretty dull colored.....Mel

from the conversation on that board I gather the form and color are rarely found. It garnered a lot of ooohs and aahs (justly so, I think!). Just really a neat piece of fossil jasper.
