In the pilot for "Stargate: Atlantis", the Wraith Queen's dinner table has what appears to be the head of a Mastadge for a centerpiece. The creature appeared in the 1994 movie "Stargate" (it was the large beast that took a liking to Daniel), but didn't otherwise appear in the series. However, the creature was seen on Abydos, which is located in the Milky Way galaxy... a galaxy that the Wraith have no knowledge of at this point.
This is probably just a tip of the hat to the film that started it all, but it also makes me wonder what the Wraith Queen is doing with an animal that's indigenous to a world they can't reach.
Is the Mastadge head merely a nod to the original movie, or can this animal also be found in the Pegasus galaxy?
