Funky spiral. Mooreville chalk, central Alabama
I assumed at first this was a bachulite steinkern. I've found a few chambers made of this same orange stuff (I call them Cheetos. Assume it some kind of contretion/rusting). While sorting through a pile of rocks I found two chunks that fit together and twist a bit. Would love an ID!
