Xenomorph wall sculpture in the Ampule Room

I don't know if anyone has brought this up, but I was thinking about the Xenomorph wall sculpture in the Ampule Room. It had something that looked like the Xenomorph from ALIEN. But what was above/behind it? [url=http://www.prometheus-movie.com/media/prometheus_screencap49.jpg]Xenomorph Wall Sculpture[/url] The more I look at it, the more I wonder if it was a Queen. I've also read that there were Facehuggers along the side. I've thought about this and I don't think it was something the Engineers worshiped. I recently saw a fan-made 'Know Your Enemy' poster for Starship Troopers and I wonder if it's something like that. Does anybody have a clearer image that shows the sculpture better? (I hope this isn't a duplicate idea/post. I did use the Search function first. Honest!)
