Ron Wyatt claimed to have collaborated with Joe Zias in supposed excavations in Israel.
Here is Mr Zias's letter denying such collaboration.
Mr. Ron Wyatt is neither an archaeologist nor has he ever carried out a legally licensed excavation in Israel or Jerusalem. In order to excavate one must have at least a BA in archaeology which he does not possess despite his claims to the contrary. We are aware of his claims which border on the absurd as they have no scientific basis whatsoever nor have they ever been published in a professional journal. They fall into the category of trash which one finds in tabloids such as the National Enquirer, Sun etc. It's amazing that anyone would believe them. Furthermore, he has been throughly discredited by various Christian organizations such as Creation Research in Calif. ...

From someone who participated in one of Wyatt's expeditions.
"From medical school I remember hearing of a rare state of mind, with a long Latin name, that led its victims to concoct marvelously detailed accounts of events that were pure fabrications, yet which the story-teller himself had come to believe were absolutely true. I am inclined to believe that Wyatt was a florid example of this disorder. He was not a deliberate liar, a fraud. And some of his observations had merit. But I am convinced that some of his "discoveries" were matters which underwent transcription in his mind, and that he came to believe as true certain ideas and observations that in fact were his own inventions.
