i just ran across this article on the bbc website... check out: the story.
i tend to agree with kristi curry-rogers though... this seems a little far-fetched. it's also interesting to point out that statistically (ok, ok, only based on a couple of data points, so not really) that this planet is potentially overdue for some type of "ele" or extinction level event or large meteorite/planetoid impact. the physics involved in the fallout of such an event are awesome to say the least... people wonder why it's so hard to find fossil evidence of dinosaurs killed in the K/T boundary event, but when you realize that the ensueing global firestorm responsible for the planet-wide iridium rich clay marker layer essentially cremated/carbonized all life at the surface, it kind of makes sense.
back to reading about the physics of rainsplash driven downslope sediment grain transport... yay!
