I saw a documentary that suggested that they used a light acid to dissolve the soft rock away from a fossil like this, but I never understood how they figured out the fossil was in there in the first place.

Oh wow. So I guess the antennae are ... bony? Or whatever it is trilobites have that fossilizes?

They were arthropods, so I think it's a chitinous exoskeleton.
