Looks very similar to what I found yesterday as well. As a matter of fact I was going to post picture and ask same question. Only difference is ones I found are a little bigger, about the size of a marble. Are those hard like a nut, the ones I found are. I did find 1 pile of deer droppings close by so I am kind of assuming they are eating them. I thought maybe beech nuts but am not sure. I am hunting Scott County and these were the only thing I found on the ground, could not find a single acorn anywhere on the ground.
