What should I name it? It's a member of the species Elrathia kingii, one of the more common trilobites in North America. Basically they're ancient water bugs. One of the coolest things about trilobites, as far as I'm concerned, is they had eyes made out of little prisms of calcite. Some species had one little calcite lens, some had thousands. I can't really tell how many my little guy had.
Speaking of cool eyes, though, my favorite all-time eyeball has to go to this guy, Dunkleosteus:
Armoured eyeballs! How cool is that?? Well, she pretty much had armour everywhere. Even her teeth were just big sharp shards of bone sticking out of her jaws.
