TODO:

• earthy colors for eras/epochs, but keep it dark -> light going past -> present
• flip view - time on top, minerals on bottom so INCREASING rather than inverted

Note these abbreviations from Eli:

I think it is good to include the full names for Hadean, Archean, Proterozoic, Phanerozoic, then you could abbreviate the shorter time periods. They end up being almost the same (the only outlier is the Cenozoic): Eoarchean = Eo; Paleoarchean = Paleo; Mesoarchean = Meso; Neoarchean = Neo Paleoproterozoic = Paleo; Mesoproterozoic = Meso; Neoproterozoic = Neo Paleozoic = Paleo; Mesozoic = Meso; Cenozoic = Ceno
