Derelict, or not Derelict ? That is the question.

There may have been something unique to that planetoid's atmosphere that caused rapid Fossilisation. Perhaps caused by the derelict itself crashing and releasing some sort of chemical? That's a far better explanation than the lazy time travel shit. I think it is the Derelict by the way.

The planets atmosphere Theory i like that I still think its differant and somewhere else entirly as Ridley does say dna to the movie???????

Never did quite look like the SJ/Pilot was fossilized (turned to stone) more like freezer burned/dried out in the cold dry air. Would not take much time to do that.

Go back to alien and listen to what dallas says to ash about the Atmosphere of the planetoid that get his attention.....:)

i think and hope its the same ship. and i dont really buy this time travel crap...

time travels been done, really dont think thats the deal here.....they (our hereos) get stranded on this planet, so some how they have to get off, its how do they, if they even do? and who paved that road in the preview of them heading towards there spaceship.....odd, thats its even smooth.....

My gut tells me it is the same ship....but it doesn't have to be and let's remember....in one of the 30 sec teasers for the teaser trailer, Ridley says, "they find an establishment which is not what they expect it to be...." Who know what that is, the ship, some other structure. Who knows....my gut just tells me it's the same ship...all we've seen so far sets that up properly.......... ............and as to the concerns about topography, geological appearance and a supposed discrepency that would have with 'Alien'......we've only seen a few brief and barely defined shots. That is one hell of a massive ship crashing from God knows what altitude....there's no way at this point to tell exactly how it will land, where and what that will look like....it could slide upon landing and end up in the visual topography of 'Alien' when all is said and done....there just isn't enough in what we have to know for sure and barely enough to speculate....I think we need a bit more before drawing that line in the sand.

Oh ukalien no...time travel would be awful...please God, no......that would just be cheap and easy...too easy. Time travel, as a plot line, is almost impossible to use anymore without the material coming off as lazy and trite. Please...no time travel..

Why do we assume the SJ from A L I E N is fossilized and therefore millions of years old? Recall that photo a few few months back in which the body of a SJ is laying to the right of the two women inspecting a spherical object with their flashlights. The SJ body appears bony, sinuous and every bit the same condition as the SJ in ALIEN. By that logic, the alien craft sen in the trailer could certainly be the same one seen in ALIEN.

Also...with the likelihood that the SJ is a suit, as Ridley HAS said, there's no telling what the makeup of that technology is and what, as @Cypher put it, the atmosphere of that planetoid could do to it in a short period of time, especially considering that it's integrity was compromised ('it looks like he exploded from inside'). What if it's literally biomechanical in nature and the elemental makeup of that atmosphere simply has a remarkably degrading effect on it once its integrity is breached.......

Just throwing this out there, but the trailer implies that the derelict crash is at the very end, but it does stay remarkably intact considering it does crash. The engineer who activates the chair may come later or earlier than it appears to in the trailer... The ship does stay intact during the crash. Maybe it's still airworthy and still a threat after being knocked down. If Shaw does in fact end up in the chair (based on another thread's discussions), then it's not completely impossible that it leaves the planet seen in the trailer AFTER the crash landing. There is nothing in the trailer that explains exactly WHY or WHEN the derelict shows up, or who is driving when it does. If taking the derelict out by ramming it failed to actually stop it from being the "weapon" it is supposed to be, then someone getting into a suit to pilot it elsewhere as a last-ditch effort is at least a possibility. It would certainly explain the apparently different final resting place of it from Prometheus to Alien, without needing two derelicts in the original story. Just an idea, anyway.

it'd be one giant coincidence. they both fell in identical position. photos of the filming location looks like the alien planetoid. my vote goes towards same ship.
