Pete,
I put a photo of the coprolites on the trip site.
Sorry about the quality.

Steve,

You will probably be pleased to know Kevin took home several fist sized 
specimens of shale full of coprolites from this trip. He was showing 
them off before he packed them away. I've never seen richer specimens 
from the mine (but an 8 year old on this trip came really, really, 
close).

I'll be looking for your jawbone. I have a daughter at GVSU.
