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?
The difference in 40 vs 60 years is big but 4 million vs 6 million is not. For 40 million vs 60 million, most people probably didn’t notice unless they were pretty tuned into dino history.
2 million years isn’t big? Pssssshhhhh!!! Doubt YOU’LL live that long.
