Chris, the most highly allocthonous of the SciBlings, just did something neat over at his place that immediately called for emulation. He’s a geologist, and he’s graphed what periods of Earth’s history he’s been studying when. So, Dear Reader, here’s my graph: not as pretty as Chris’s, but hopefully legible. You may note that I specialise in the later 1st Millennium, that my work in the Neolithic must be rather superficial, that I have never worked with the Mesolithic nor the Early Iron Age nor the Middle Ages, and that I plan to return to Bronze Age studies next year.
Oh, and one more thing. My graph covers six thousand years. Chris’s covers billions.
