"Fish" is a folk taxon. It's not a real clade.

This. "Fish" is the most paraphyletic taxon in existence. Any mention of (((fish))) is sure to trigger taxonomists.

What do you mean by fish OP? Osteichthyes?

conodonts are the earliest known craniates afaik

there are older ancestors though. Tunicates for example are the oldest known chordates.

and we know they evolved from other interesting types of plankton and even earlier single cells and benthic colonial organisms.
