UPDATE: Alien Skull found, DNA "Not From Earth"

"The "Starchild" is a real, true bone skull independently dated by Carbon-14 to be 900 years old (+/- 40 years). Research indicates is unlike any human skull ever before recorded. The name "Starchild" is the result of early X-rays taken of the skull and maxilla fragment found with it, which showed unerupted teeth that, combined with the smaller-than-normal-adult size of the skull, indicated a child of age 5 or 6 . A second skull was found with the Starchild, a normal, adult female of small stature , also C-14 dated to 900 years ago (± 40) , and biochemically shown to have lived in the same general area as the Starchild. This second skull is often used for comparison to the Starchild.
From its extremely shallow eye sockets to the total lack of frontal sinuses, the Starchild skull's morphology cannot be accounted for by any known combination of deformities. The bone is half as thick , weighs half as much [13], and is substantially more durable than normal human bone--unlike anything currently in the scientific record. Furthermore, inside that unusual bone are microscopic fibers and a reddish residue that so far defy any explanation ."
