Need Help ID'ing Iron Looking Rock

Hello All,

I just got back from South Texas doing some Indian Artifact hunting, and stumbled upon this one area that had this type rock scattered in an open area.

From the looks, it appears to be Rusty Iron, and seems to be heavier than it should be.

I put my pinpointer too it and nothing..So i dont think there is any Iron in at all.

Im sure this is a Rookie question, But does anyone know what this is called?

thanks in advance!!

I don't think its iron if it doesn't ring up on a detector but just in case try a magnet.
