For some weekend fun, try to guess what this is a fossil of. (Yes, fossil guessing games are considered "fun" at Leave the lights on.) This object was unearthed in a paleontologist's yard by Hurricane Ike. Makes me wonder how many unrecognized fossils were unearthed in non-paleontologists' yards!

The first person to guess correctly, or the person whose guess is closest, will get, well, some sort of prize. I'm thinking a lovely graphic. It may not be good sportsmanship to use Google to help you, but if you're comfortable with it, then nothing is stopping you.
