Bob Cornuke and Noah's Ark in Iran?

And how does one test for petrified wood? My guess would have been by looking at it with an experienced eye to see if it had any of the morphological characters of known petrified wood: mineralogy would tell you almost nothing, I would think. (Unless it's basalt - I'd like to see a mechanism for replacement of wood by basalt. Or granite.) I realize this is apologetics/journalism we're getting, but I'd really like to know what tests they ran.....

I'm calling bullshit. What would such a test consist of? Microscopic examination I might buy, but chemical tests are a bit chancy. Was there something here about organic vs. inorganic carbon content? Shale sometimes has a large organic carbon component. If these folks have any "facts," why won't they say what those facts are?
