Jaffa fossils
I don't think that the fossilized guards were coming through the Stargate. Even disregarding the wormhole physics in the show—such as the Stargate being unable to activate if buried or matter being squashed against a barrier—I think that they were guards who were killed in the Tau'ri rebellion, then buried with the Stargate. -- SFH 01:29, 29 December 2006 (UTC)
