It was a baculites graveyard

Fossil Friday once again! This is the last of the South Dakota exploration trip, hunting the Pierre shale for cephalopods and hopefully a mosasaur.  Although the first half of the Pierre shale exploration went pretty slow, it wasnt without a few nice finds.  The second part, we were extremely fortunate in that we got to meet Neal Larson and hear a short talk about the local Pierre shale formation, and then he took us out to his personal hunting site.
