[edit] History

The starchild skull came into the possession of Lloyd Pye, a writer and lecturer in the field of alternative knowledge, in February 1999.^[1] According to Pye, the skull was found around 1930 in a mine tunnel about 100 miles (200 km) southwest of the Mexican city of Chihuahua, Chihuahua, buried alongside a normal human skeleton which was exposed and lying supine on the surface of the tunnel.^[2]

The skull is abnormal in several aspects. A dentist determined that it was a child's skull, due to unerupted teeth being impacted in the associated upper right maxilla found with the skull.^[3] However, the volume of the interior of the starchild skull is 1600 cubic centimeters, which is 200 cm³ larger than the average adult's brain, and 400 cm³ larger than an adult of the same approximate size. The orbits are oval and shallow, with the optic nerve canal situated at the bottom of the orbit instead of at the back. There are no frontal sinuses.^[2] The back of the skull is flattened, but not by artificial means. The skull consists of calcium hydroxyapatite, the normal material of mammalian bone, but there is an overload of collagen in it, much more than is usual for human bone.^[4]

Carbon 14 dating was performed twice, the first on the normal human skull at the University of California at Riverside in 1999, and on the Starchild skull in 2004 at Beta Analytic in Miami, the largest radiocarbon dating laboratory in the world. Both independent tests gave a result of 900 years ± 40 years since death.^[5] DNA testing at Trace Genetics in 2003 recovered mitochondrial DNA and determined that the child had a human mother, though it was not the child of the skull found with it. Its mother did belong to a known Native American haplogroup, haplogroup C. However, useful lengths of nuclear DNA for further testing could not be recovered. Later testing in 2004 at the Royal Holloway Institute [1] at the University of London revealed unexplained "fibers" in the bone of the skull and a reddish residue in the cancellous bone, neither of which are known or recorded in any other bone at present existing on earth.^[6]

[edit] Paranormal Interest

Despite criticism from established science, the skull has gathered great interest within the study of UFOs and alien life forms. Some contend that it is the skull of a non-human, or a human/non-human hybrid, based on the shape of the skull bearing similarities to the common grey representation of aliens. Attempts to extract nuclear DNA to confirm or refute this belief were unsuccessful.^[7]

Lloyd Pye believes that the starchild skull is the result of genetic engineering by aliens, creating a human-alien hybrid.^[2] Other explanations have included the use of cradle boarding on a hydrocephalic child,^[8] brachycephaly, or Crouzon syndrome.^[9]
