Prometheus - Space Jockey suits?

Just what exactly do we have here! Are they suits? Statues? If they're suits then what goes in them and how do 'they' get into them?

I wonder if this is the end of the corridor that leads into the room we've all seen in the trailer with the Space Jockey chair in it?

Judging by the distance Noomi is away from them I'd say that the suits are about 7' tall. Now this leads to even more questions, because as you'll recall, the Space Jockey in ALIEN was gigantic, more like 25' in height. So, what are these things in the corridor??

Look at their feet, they look more like boots than 'feet'. Which makes them more likely to be suits. Are the suits made in the image of their maker?
