Ica Stones

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

The Ica Stones popped up in the 1960s from Peruvian physician Javier Cabrera, who claimed the archaeological stones showed ancient peoples riding dinosaurs and using advanced machines. 

They caused a stir, and were used frequently by creationists to say, “look, see, dinosaurs and humans living together! Except it turns out it was all a heaping triceratops hoax. The stones were provided by a farmer who made the engravings on river stones then baked them in dung to look old, before selling them on at a huge profit. Every instance of analysis performed on hundreds of stones he crafted revealed them all to be modern with none of the wear of thousands of years.
