Hey West!

I did one of those charts a long time ago. Gosh, 55 60 years ago. I don't remember the time scale, I think 1mm=500,000 years. It was over 80 feet long.

I just checked mine: 10 million years = about 1/2 inch. Yours is about 6.3 million years per 1/2 inch. But then, the last roughly 10% of my chart is an expanded view of the last 3 million years or more, so the actual linear chart is probably more around 40 feet. So yeah, assuming my original number is accurate, a quick calculation places yours up around 70 feet or more!

I just remember it wrapping around the entire lecture hall.

All that time, and self-aware homo sapiens just recently sprung up out of the Darwinian lotto game.
