From the Permian to Star Wars and vice-versa

I was reading some scientific papers on the Permian period.  It's a time in Earth history I've always been interested in (along with the following, Triassic, period).  There are some interesting articles on how extreme Greenhouse conditions brought about the extinction of most of life on Earth.  Anyway, I've written about it on Palaeos com.  Compared to my old standards, the page is pretty rough and incomplete; although it's an interesting and popular subject, due to people's infatuation with things like mass extinction and other apocalyptic or post-apocalyptic scenarios. 

Also today, browsed a few sci fi wikis, including one called Wookieepedia; a gigantic Star Wars based Wiki.  Amazing labour of love.  And while on the subject of Star Wars, what could be more brilliant than the very cool Weird Al Yankovic and his brilliant parady - The Saga Begins (to the music of Don McLean's American Pie)
