1953: The British Natural History Museum announces that the "Piltdown Man" skull, initially believed to be one of the most important fossilized hominid skulls ever found, is a hoax. The jawbone was found to be that of a modern ape -- most likely an orangutan -- that had been treated with chemicals to make it look as though it had been lying in the ground for hundreds of centuries. The cap of the skull was still thought to be a genuine fossil, but far more recent than originally believed.
