I don't have reason to think it was a hoax. I know it was because I read the headlines in the newspaper that stated it was a hoax.
At the same meeting, Woodward announced that a reconstruction of the fragments indicated that the skull was in many ways similar to that of a modern human, except for the
occiput (the part of the skull that sits on the
spinal column) and for
brain size, which was about two-thirds that of a modern human. He went on to indicate that save for the presence of two human-like
molar teeth, the jaw bone found would be indistinguishable from that of a modern, young
chimpanzee. From the British Museum's reconstruction of the skull, Woodward proposed that Piltdown man represented an evolutionary
missing linkbetween apes and humans, since the combination of a human-like cranium with an ape-like jaw tended to support the notion then prevailing in England that human evolution began with the brain.
In November 1953,
Time published evidence gathered variously by
Kenneth Page Oakley,
Sir Wilfrid Edward Le Gros Clarkand
Joseph Weiner proving that the Piltdown Man was a forgery
[12] 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. Microscopic examination revealed file-marks on the teeth, and it was deduced from this that someone had modified the teeth to a shape more suited to a human diet.
I don't think of the shroud of turin.
