How many bytes in a trilobite?

In this case, eight billion. After carvng two tiki mask USBs last December, I put aside my knives for a few weeks. Now I'm back. I'm still playing with design ideas. My latest was inspired by my trilobite post being included in the forthcoming Open Laboratory: The Best Writing on Science Blogs, 2010.

I spent a ridiculous amount of time working on this one, researching trilobite anatomy and staring at the piece of wood trying to figure out how to make it work. The wood is unfinished pine. Inside is an 8GB Lexar drive

I've based my critter roughly on photographs of the genus Dalmanites, but not on a single species. Sam Gon's Guide to the Orders of Trilobites was an indispensible resource, though any mistakes or liberties I've taken are my own and he is no way to blame.
