I found this in a pile of rock removed from a field on the family farm. It is about the size of my hand and it is very dense, weighing about as much as concrete. One side is pretty smooth, while the other almost appears to have scales. It is shaped like the spade suit in cards. Thanks

Looks like a boxer turtle shell to me?

I do not think it is a turtle shell. To solid

I might be way off, but I think that might be an oxen or other large bovine gallstone. Big bucks if it was preserved. A few examples in the photo.

Looks like a piece of hematite to me. Natural, not a fossil or artifact.

Took me bit to figure out if it was Hematite.
Then looking under rough Hematite I saw some very similar colour examples.

That was my first thought. A turtle or a once long gone animal-plant? of some kind. I was in a coal mine one time in the NW corner of New Mexico. The mine manager took us on a little tour in his atv type buggy and he pointed out several fossilized turtles in the seams, among other fossils of plants that once lived in a vast swamp. You would also see methane gas bubbling and hissing in various places. It was all controlled by massive mine ventilation, so there was no concern for an ignition.

I also think it is a hematite or limonite concretion.
