@Lonely Universe, yeah, also could be inspired by Alien Monster IV by H.R.Giger...but what about the green crystal?
Well, I have a theory about that...and I think that Perhaps it is a fossil which contains the DNA of a primordial monster, like amber:
And the black goo extracted DNA from the beast to create similar life forms:
My thoughts are inspired by swarm of black scarab in earlier drafts of Prometheus which was written by Jon Spaihts. There, these nanomachines extract the DNA from a creature to create something based on that original life form.
And I still think about the parallelism with the myth of Prometheus. Perhaps an engineer was sacrificed (as punishment?) in order to create the monster.
