Trilobite - First Facehugger?

The creature which is born from Shaw as a result of an infected Holloway grows up to be a massive, squid-like monster which overpowers our evil Engineer. Thanks to the recent scans from [b]Prometheus: Art of the Film[/b] we now have a clearer understanding of the design of this new Alien.

Thankfully Shaw was able to remove it via the Med Pod before this happened, but if she hadn't, guaranteed this scene would have been much more gruesome.

In the scenes which follow the Engineer's attack on Shaw, Shaw releases the adult Trilobite on the Engineer and form the draft sketches as well as in the film we see just how powerful this new creature is.

Now, the initial "Facehugger" could have still been around before the "Trilobite" even, and the Trilobite could even be of the same type of species of symbiotic parasite. What are your thoughts on this Fagehugging Alien? I personally find it very interesting and I rather like the design the studio chose to use for it!
