 In November 1953, "Time" magazine published evidence gathered variously by Kenneth Page Oakley, Sir Wilfrid Edward Le Gros Clark and Joseph Weiner proving that the Piltdown Man was a forgery and demonstrating that the fossil was a composite of three distinct species.It consisted of a human skull of medieval age, the 500-year-old lower jaw of an orangutan and chimpanzee fossil teeth.Someone had created the appearance of age by staining the bones with an iron solution and chromic acid.
