Some stuff...

Changed the title again. Blood on the Asphalt is actually the name of a free online "CD" you can download that takes the melodies of the familiar Street Fighter 2 songs and "remixes" them. Remakes them, honestly. It's a tribute album. Some of them are pretty weird. Many of them are excellent. Anyway, I'm going to temporarily steal their name because it's cool. http://sf2.ocremix.org/

Other than that, I've been keeping on keeping on. Not much to report. For fun, I've been creating a spreadsheet of all the earth's ages, their names, subdivisions, date that it started (in millions of years ago) and ended, total length, and a few comments. Unlike most such lists, mine doesn't start at the top and go backwards, which I've never found intuitive; it starts at the beginning and goes forward. Imagine that. That's the main reason I did it; to have it all in one place in an intuitive format, but it's also fun to see the time frames. One interesting side effect of looking at all this has been surprising to me.

I'm used to looking at dinosaur ages, and I guess it never occurred to me just how remarkable it is that dinosaurs were on the earth for 160 million years, and that they dominated the fauna for a good 140 or more of those 160 million years. Mammals have been around a good 200 million years and dominated the world for about 65 million---but the terrestrial megafauna dynasties prior to the dinosaurs are surprisingly short. In fact, I never really thought about it, but it was less than 150 million years before the first dinosaur that Ichthyostega and Acanthostega were the first tetrapods to lumber their way out of the water on occasion. At the K-T extinction event, when the non-avian dinosaurs went extinct, they had dominated the terrestrial megafauna for more than half of the time that there had even been a terrestrial megafauna to dominate!
