Hi all!
I'm probably fighting off a minor cold, which means I'm feeling on the run down side. So, I figured if I'm not going to be productive anyway, I'd share something just plain cool (in a science-y way).
Yesterday morning, my wife and I went to a rock and mineral show, and we bought a couple of fossils. She got a Jurassic-era ammonite, and I got a 412 million year old trilobite.
It may just be an accident of fossilization (this particular trilobite was broken in half during the process, and had to be glued back together during restoration), but my trilobite has a very lively pose. It is rearing up and to the side, as though caught in the middle of a turn. It is about two and a half inches long, and its tail curls down at the back.
Where this gets sort of cool - besides the fact that if you actually start trying to wrap your brain around "412 million years old" it promptly melts - is that if you think about it, this isn't even the original trilobite. The original trilobite is long gone, replaced by minerals during fossilization. This is the ghost of a little sea creature that lived entire geological ages before the Dinosaurs.
I just thought that was cool and worth sharing.
