Nautiloid Lineage

What is the correct way to describe how far the extant species of nautilus can be traced back?

Depending on the paper, they can be traced back to 400 or 500 million years ago. So, do you simply say that the nautilus lineage can be traced back that far? Is lineage the correct term?

I just had a meeting with the public relations director at my college about a paper I am working on and I was getting into the details of nautilus and why they are called a living fossil (a term that I hate) so I was just wondering if there is a particular way to state this.
