Are these some kind of fossils?

I was in the woods on my dad's property in western Pennsylvania and noticed an unusually shaped limestone rock sticking out of the hillside so I pulled it out to examine it. It looks like the shape of some kind of giant vertebrate bone. I told my dad and he said there are 5 or 6 similar ones in the immediate area. He even put one in his garden because it looked neat. I was able to locate 3 of them and if they are something interesting will try to find the others in the thick brush. Here are pics of one of them.
