Another ID needed

Hi this is another one that my granddaughter and I found along the creek bed in house springs, mo. I can tell that it is a bone. I did the tongue test thing and my tongue did stick to it. ( Gross just thinking about it)  I'm assuming it's some sort of bone of a deer however we have so many wild and domestic animals around here it could be anything. The granola bar in the last pic of the bone is there to hold it on its size. It's about 5-6" long. Any help would be greatly appreciated. What animal and what bone would be fantastic. Then the last pics were also found around in the same location. I know there are spiral (screw like) fossils in this as well just can't remember what they are called. I'm interested in the fan shaped thing. Thanks everyone!!!!
