Creature of the ... Foggy Lagoon?

Hi all
While in San Fran, wandering a beach south of the city, we noticed this (see below).
I wondered if this were a trilobite, but the others warned me not to delve too deep, for fears that I would awaken an ancient creature.
This ...thing was firmly adherent to the rock beneath, and I turn to you, o internet masses, for your speculations and declarations: anyone confidently able to identify this?
Thanks in advance!

Addendum: Thanks to Google Image Search, I'm now guessing this is a Chiton. http://en.wikipedia.org/wiki/Chiton

What do you think?
