I came across this today. I thought I’d share it on here.

Not that the charts differ significantly from year to year, but I liked this link because it has quite a bit of info all in one place. It might be more useful for those who are academically and research inclined.
They also have it available in many different languages for those who do not have English as their first language.
For those of you who collect in the Ordovician, they have a very nice detailed chart at the link below.
