Something like that would be insanely easy to fake if there was no good chain of custody of the evidence. Take any old Canopic jar, stick a small camcorder inside and x-ray it would be the easiest. I can't imagine it would be too difficult to photoshop the image, too.

Unless you can prove that thing was pulled out of the ground with a camcorder inside, and that the tomb was not touched recently before being "found," then it's got to be labeled BS. Occam's Razor, got to go with it especially with something this nutty.
