I came across this collection of stratigraphic charts and time scale. Since we have ongoing (and ongoing and ongoing) discussions about the age of the Earth, I thought I might post this for reference.
I do not have any particular topic for discussion in mind, just “neato charts”.

Terrific resource for geologic information which will be hand waved away as “same evidence different interpretation” by the you-know-whos.
