telenovels 28 Nov 2006 I watched this show a second time this past weekend. I don't know why, but I find it really fascinating. Especially when they are discussing the primitive "predators" like giant shrimp. I never imagined a shrimp could be considered "the earth's most dangerous predator" but apparently 200 million years ago, it was. I also enjoyed seeing the housecat-sized spider & the man-sized(!) centipede. Awesome. Makes me wish I had a time machine, so I could send back a small Mars-type rover to study ancient biology. They ought to make more of these shows. Enough about dinosaurs & cavemen. Let's see what existed *before* the dinosaurs arrived.
