With my daughter's newfound love of mineral collecting, I tend to watch for interesting items near the river, again, as in my youth.
I often find colored quarts (she loves the pinks), broken spear or arrow heads, various metamorphic or striated sedimentary formations, limestone with shells exposed (kind of fun to find in landlocked Indiana), etc. So common in Indiana that people lose interest, but not me and now my daughter has some interest.
Today, I found an interesting fossil, Not just another petrified coral either.
I have seen quite a few of these in museums and such and I found a piece of a small bone about two inches long with mineralized marrow clearly visible and the structure of the bone is well defined.
It means nothing in the grand scheme, but it will please and surprise her when she returns from work.
