Shaw mentions that there must have been an "outbreak" on the ship, based on knowledge gathered and those visual, green recordings we saw of the Engineers.
I'm thinking the outbreak was of the xenomorph/deacon/whatever-else-we-haven't-seen variety. Here's why:
1) When the first recording gets played by David activating a panel while first exploring the Juggernaut, a shriek can be heard that sounds nearly identical to the Deacon's shriek heard at the end of the film.
2) While bumbling around like idiots, Millburn and Fifield discover the pile of bodies. Millburn mentions how at least one of the Engineers' suits is burst open from the inside.
3) This photo of the "pilot room" where 3 Engineers are dead, and the one is still alive in stasis. The Engineer's body is clearly burst open, along with the "glass/plastic" being burst open.

Possibly more evidence laying around.
