A friend brought my daughters a coprolite of some ~30K cat scat that had a lot of character, but we have misplaced it (temporarily, I hope). When they were much younger, the kids would call each other names a bit differently than other kids, "You silly coprolite! You're a coprolite!" "I'm not a coprolite! YOU'RE a coprolite."

Coincidentally, I was perusing some old favorite links just a few days ago and came across http://www.coprolite.com
