There some life forms on earth that will never become preserved. Squids for example are a high ammonium based life form. The Ammonium prevents fossilization. If humans didn't exist while they do, we would have never known about them. [0] There would have been no preserved record.

Being entirely naive to squid prehistory, the wikipedia page for squid shows two apparent-to-me squid fossils [0]. Is there some nuance here that I'm not aware of?

Not sure about squids in particular, but the easiest way isn't necessarily to find remains, but to see negative prints on sediments.

Tons of fossils are "negative prints on sediments". GP's assertion that "If humans didn't exist while they do, we would have never known about them" is clearly wrong.

Is there a marine equivalent of amber that things can be trapped in and preserved?

Apart from ice I guess.
