Fossilized remains found in Patagonia, Argentina back in 2009 represent a new genus and species of plant-eating dinosaur that belonged to a group called Rebbachisauridae.
On a human-scale timeframe? Yeah, sure. On evolutionary timescales? According to a PDF by “Charles Sibley” whose content I can only see a small Google snippet of, “Galliformes and Craciformes diverged at a 21.6.” (I assume that’s 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.
I thought all dinosaur species were very old.
