felecia187so the rover has sent back pictures that show something that looks like a thigh bone , now when you look in the circle it dos look like a thigh bone but if you look out side the circle you will see that the same colored dirt that the thigh bone is made of is also the same color as the surrounding land scape if it were a thigh bone it would be white and would show tiny holes in the top part so is this a thigh bone on mars no just something that looks like it so sorry to burst your bubble but facts are facts and the fact is this is just a rock that looks like a thigh bone , enjoy
