I am constantly amazed at the wide variety of life-forms that predate us. This is a timely link too, in that about 12 hours from now, I and a friend are going to prowl around a nearby rock quarry in search of fossils. Of course, what we're likely to find are mostly coral reef organisms. I'm hoping to find a whole urchin, or maybe a brittle star. The rocks here are way too old for whales.
