    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.

    This old thread (post #2) has some info on lineage of Nautilus.

    Lineage works, or you could say it's ancestors date back to 400-500 Ma (Million years ago).

    Thanks Kevin. So, it is the Order Nautilida that can be traced back before the Devonian?

    Not before the Devonian, from Phil's chart thread. :smile:


    Nautilida came from either Orthoceratida or Oncoceratida (some think Tarphyceratida)
