Neat!
Minor notes:
1) He uses the latest stratigraphic findings in putting the end of the Cretaceous at 66mya, rather than the more-typically-cited 65mya from older charts. (What’s a million years here or there?)
2) The art from 2016 labels the post-Cretaceous as “T” for Triassic, the old nomenclature; the art from 2017 uses the most recent nomenclature (Pg/Paleogene).
I approve of attention to detail.
Where is that top artwork? I can’t find it on the website.

Have you been practicing?
Me @#1:
Blarg! The bottommost/earlier “T” stands for “Triassic”; the upper/later “T” stands for Tertiary, which is the old nomenclature. Triassic is still the standard usage for that period (and is abbreviated “Tr” to avoid ambiguity).
