We're not sure if Bud's Indiana mineral find started out as a fossil coral or clam, but it looked so nice we wanted to post it anyway. If you are familiar with Indiana geology, please leave a comment to help us identify it.
Fossil Collector: Bud N.
Location: Indiana
It appears to be a geode with secondary and tertiary growths of quartz. I don’t see fossil. It is very similar to Mississippian geodes of neighboring states.
I agree. I have a couple geodes that look much like this inside.
I live in Michigan, and hunt geodes since I was a child. It appears to me a geode.
