In 1869 in the USA newspaper there was the case of the "giant fo Cardiff". Someone pretended, he had found huge petrified bones...Mark Twain, bored by the petrification mania of that time invented a story on the marble Venus of the Capitole in Rome and wrote an article affirming that it wasn't a sculpture but a prehistoric woman petrified by sediments etc.People didn't always realize that it was a joke, and other newspapers published his article as if it was a scientific paper.
