The first poster for the film (due May 22) featured part of the title relic, but there was always something odd about the eye socket. In the follow-up, also by sci-fi/fantasy movie artist Drew Struzan, it's clear the skull is not at all human. Add to that the recent trailer, with its shot of a crate labeled "Roswell, New Mexico 1947," and you don't need to be a professor of archaeology to put the pieces together.
