Paramount Pictures has revealed another Indiana Jones and the Kingdom of the Crystal Skull poster over at USA Today, in lieu of this week's ShoWest convention. Take a look:

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.

Other clues: Looks as if our hero will face his least-favorite animal and the locals at some Maya ruins. Karen Allen (who also was in 1981's original) seems to be enjoying herself, though.
