With a slight chance of rain, my father and I decided to go hunt the Maquoketa, Galena, and Dubuque formations in Southeast Minnesota. We got to the first spot at about 6:30am and were getting rained on before 7:00. The site was in the Maquoketa Formation and the best way to find stuff is by splitting the limestone. After almost 2 hours of prying up slabs and splitting them we decided to call it quits and move on. The rain and the fact we weren't finding much were the primary motivators. No photos because all I brought home were a couple Hindia Sponges which are now at my father's house. Our next stop was a site where I had found a slab with very rare Celtencrinurus sp. parts earlier this month. I had wanted to get back to see if we could find more of the layer and possibly some more parts. I also wanted to take a measurement so I could record exactly how high above the Cummingsville Formation contact the previous specimens were collected. They were in place on the bedding plane so an accurate measurement would have been possible... if I had remembered my tape measure. Guess I'll have to go back. Anyway we didn't find any more parts of Celtencrinurus sp. in the rest of the slab or anywhere else. We continued to hunt for a little while longer and I found an interesting piece that could turn out to be a decent Ceraurus sp. A bit of prep will reveal if it's a complete specimen or not. By this time it was about 11:30 and we were getting hungry so we went to grab some lunch. Ceraurus sp. (Complete?) Cephalopod During lunch we decided to hit two more quarries in the area, one in the Galena Formation and one in the Dubuque Formation. We got to the Galena quarry and started looking slabs over for trilobite parts and echinoderms. After not finding a whole lot I stumbled across a large Thaleops laurentiana. It has a chunk broken out of it's head, but there are thoracic segments showing so hopefully it will prep out decent(pictures to be taken). I also picked up a rather interesting geodized cepahlopod that I thought was pretty cool. Geodized Cephalopod Final stop of the day in next post.
