While journeying back out to the Mississippi River, I decided to also stop along the Meramec River in St. Louis. There are exposures of Mississippian aged Warsaw Formation along the river. I passed one, and turned around quickly to try my chances at finding a nice crinoid calyx. There was a lot of rock exposed, but not much of it was fossiliferous. Much of the rock was caked in mud and thick dirt, which made finding anything difficult. After a few hours, I did finally manage to find something worthwhile. It was a nice Agaricocrinus crinoid calyx, exposed in the hard bedrock. Unfortunately, no amount of chipping or pounding was going to get this out of the hard bedrock. Luckily, I had a new grinder in my car I had purchased last week that came with a diamond tipped blade. I had never used a grinder or saw before to extract a fossil from rock, but thought this would be a good opportunity to try and do so. Geared up with my PPE, I used my grinder to put in two relief cuts. Success! The two cuts made it a breeze to knock out with a hammer and chisel. The crinoid is dirty now, but will clean up nicely when I get time to put towards it. I packed up my trophy, and decided to drive out to my campsite for the night. The next morning, I took off to a couple of spots along the Mississippi River. There is a lot of rock along the river and in the area, so research is a must! You could wander around a ton of rock and never find a fossil. I had a secret spot mapped out, and today I was not completely disappointed. I had found the Bainbridge Formation rock I was looking for, though unfortunately there was very little rock exposed. A lot of time was spent carefully scouring the few slabs of exposed stone. Here were a few complete, but weathered Calymene trilobites. Many unsuccessful attempts later, I finally found one I thought that was worth trying to clean up. You can see a small portion of the cephalon exposed. I gathered a few more non photo worthy trilo-bits for my collection, and packed up my finds. I had a long walk back to my car. Once I got back, my curiosity got the best of me so I spent some time picking away at my last exciting find. I carefully exposed it a little bit, but will stop here for now. I am fairly confident it will be a complete Calymene trilobite! A definite happy end to my weekend off work.

I stumbled upon a small patch of Warsaw Formation limestone and found a couple of cool Chondrichthyes teeth. Both teeth were unfortunately cracked/ split in the matrix, and the tough limestone bedrock made removal tricky. The smaller tooth looks like Cladodont of some sort. I can't ID or recognize the bigger toothplate, and was curious if anyone has possibly seen one similar?

I've had some difficulty narrowing down the identity on some assorted brachiopods. The diagnostic features may not be preserved but I figured I'd post them here to see if anyone knew. @Tidgy's Dad Any ideas? The first is a single large valve from the Warsaw Formation in Fenton, Missouri (The old Meramec Bridge site). I've been able to track down most species reported from here and identify everything else but this one is harder. The wear doesn't help. The second are a couple o Echinoconchidae valve casts in chert from a creek in Lincoln County, Missouri. It could be residual chert. The area is otherwise Ordovician. 2.8 cm width x 2.5 cm height. 3.8 cm x 3.2 cm

I took my 4 year old Son geode and fossil hunting near the Missouri, Iowa, Illinois borders last weekend. We had a blast and found a lot of cool stuff. I found this calyx in the Warsaw formation which is Mississippian. It's obviously not done being prepped, but i figured there might be enough showing to get your opinions. It's actually been quite a challenging prep and may take some time to finish. I was thinking a possible Agaricocrinus sp., but it doesn't quite fit the bill. I can't find anything that looks identical. Any help is appreciated. @crinus @Crinoid Queen you guys still around? As found Some prep
