Can the Ica Stones be independently authenticated?
Genuine pre-Columbian burial stones (‘Ica stones’) can be distinguished from
modern souvenir stones by patina analysis and metallurgical analysis. The Palpa
Museum stone bearing etchings of a sauropod dinosaur and other animals was
confirmed as ancient. Such analyses can confirm (or refute) the antiquity of the
many other Ica stones bearing dinosaur images.
