Hi All, I found this specimen in northern Missouri many years ago around when I was eight - and recently rediscovered it while going through my childhood rock collection. The creek I found it in cuts through the Marmaton group. It's about 2 cm at it's widest (marks in mm). I guess my first question is if it's actually a trilobite pygidium and secondly if there's any chance of an identification with as much damage as it's received? 1: 2: 3: Thanks! - James

I was fortunate to be able to take two trips recently to the Marmaton group in Northern Missouri and wanted to share my trip report with the forum. It's hard to find information on the Marmaton in Missouri, and I struggled with the geology and understanding what members within the Marmaton I was seeing, but I had a great time non the less. I grew up in this region and have some ‘insiders’ information on a few spots I wanted to check out just from spending time running around the countryside as a kid. The first was in a local creek in the township I grew up in that contains concretions we called ‘dragon eggs.’ I was curious if they would contain fossils so on my first trip in early September I committed to breaking one open. First, here are a few pictures of the site: I was able to break this one open, and it did contain fossils! The blue line on the lower left marks a very thin layer of limestone that the concretions seem to form right above. Here are a few more pictures of the concretions for reference. A particularly large one: And one that is just cracked: Unfortunately for me only the very first one I broke had any fossils. I spent several hours hoping another would reveal some but luck was against me at that point I guess and I failed to find a single one. Frustrated I spent the remainder of the evening searching through the fallen limestone exposures. The next post will contain some of the specimens from the single fossiliferous concretion and the limestone.

I recently got to do some hunting in northern Missouri, Marmaton group and found a few large phosphatic concretions. Within one was this specimen that I am trying to identify. I am wondering if it looks like a Solenochilus sp. to anyone beside me? There may not be enough of the specimen present to determine a species ID, but I figured I'd take a shot for the sake of labeling. Thanks,
