Ed Brayton has done a good job of dissecting the claims in the announcement article. As he notes, this is far from the first such claimed discovery of Noah's Ark. This one is in Iran rather than the usual location of Agri Dagi in Turkey. I actually give them credit for not looking on Agri Dagi (Mt. Ararat), since the Bible only says that the Ark landed in a region called Ararat, not a mountain of that name (2 Kings 19:37, Jeremiah 51:27).
For a review of some previous claimed Noah's Ark sightings, see my 1993-1994 articles from Skeptic magazine, "Sun Goes Down in Flames: The Jammal Ark Hoax" and "Update on the Ark Hoax".
