I know we now know they went extinct 66 million years ago, and 64 millions is another date I’ve seen around, but how long how we known it was definitely way more than 40 millions ? I’m asking because it’s the date given in the the song “walk the dinosaurs” by Was (Not Was), and I wondered why such a number. Would it have seed credible at the time, or was it just arbitrary?

    I subscribed to all sorts of newsletters, and at least one was dinosaur specific. I would also write professors at local colleges with questions and usually get a response.

    Also worked at the library and could order just about any book available. At that point most libraries would order books if they didn’t have them already.

    But mostly newsletters and science journals until BBS became more common and user friendly when we first started having available computers.
