Couple of rocks/fossils. Help please

[Unit70]

Posted these on Native American artifacts because they were found where several artifacts were found. The consensus was, they were rocks Couple appeared to be fossils and was recommended to post them here. Front and back of disk with holes are the first two photos and the next 3 of a pine cone looking rock. Any thoughts would be nice. Thanks

They resemble geodes that I used to find on my grandparents farm in Southern Indiana
