Still just finding bits. Two pygidia in one piece, and a small cephalon. This entire area must have been a shell pile like you see at the beach today. You know, the ones you have to walk around when bare footed. Nothing but shells, bits n' pieces. Cheers.
This is #8 and #9. Both were in the same split of shale. The larger one was barely visible, just 1/2 of the fwd center ridge. Took quite a bit of digging to expose it. I was pretty sure what it was, getting used to the little clues. Thanks again !
Since I was on spring break and finally had a Saturday off, I decided to drive a few hours south to a couple of the best Mississippian exposures in my area. I've been to these spots in the past and have always had a pretty decent haul. Here are some of my finds from my most recent trip, enjoy! Blastoids (complete with in situ shots) Brachiopods
