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?
most people knew about geological ages and the dinosaurs where in some millions of years ago but the average person did not know how many.
