Residue In The Starchild's Bone
In 2004 matching small samples of bone was carefully cut from the Starchild Skull and the human female skull reportedly found with it. Those samples were then polished using lapidary tools, giving the first clear look at the bone structure. A second set of samples was also taken, but these were carefully snapped rather than cut to give the first views of the bone clear from the debris of cutting. These are unedited photographs taken of the results.The human bone is identified as "STARCHILD FEM1" and the Starchild Skull as "STARCHILD SCS2".
Note that, once polished, the bone of the Starchild Skull appears yellowish and opaque compared to the human skull. Both samples were treated exactly the same way, and photographs were taken in the same light and at the same scale (the human bone takes up more of the image as it is normal thickness whereas the Starchild's bone is much thinner than normal human bone). Any differences are entirely due to the nature of the bone itself.
