Vestavia Hills, AL (Ordovician to Mississippian) I found these very odd rocks exposed by recent flooding. i wondered about a tree root mold or burrow for the first one, but figured low chance of identifying. Just in case, I did a vinegar soak to remove more of the mud. Today, I saw a tiny little spiral shell. Is it a fossil? (vs a modern snail that got trapped in this sediment). Any thoughts about the overall shape of the rock? Since it was found nearby, I’m including a pic of the other weird rock. I considered part of a horseshoe crab or trilobite molt, but I can think of more arguments against than for these. Thanks for looking.
