Re: [dinosaur] Dating of dinosaur age during history

The current version is not 2018-7, but 2019-5. Go here to find whatever the current version is.











How it has improved over time?

I'd like to see that myself.







Me too. At this opportunity I'll mention that even the 2019-5 version is already outdated in at least one respect: the beginning of the Cambrian is given there as 541.0 ± 1.0 Ma ago, but really happened later, between two volcanic-ash beds dated to 538.58 ± 0.19 and 538.99 ± 0.21 Ma ago.
