I thought all dinosaur species were very old.
all dinosaur species were very old
On a human-scale timeframe? Yeah, sure. On evolutionary timescales? According to a PDF by āCharles Sibleyā whose content I can only see a small Google snippet of, āGalliformes and Craciformes diverged at a 21.6.ā (I assume thatās MYA) And certainly a lot more diversification has happened since then. Gallus domesticus is probably less than 8,000 years old.
Though a new sauropod would certainly be quite the marvel.
