These were found in O’Fallon MO in a road cut. I think in the Fern Glen formation. Any help with ID would be much appreciated!

Help! I tried to take my two fossil enthusiast boys to the Fern Glen site in imperial, MO today. We found the “pink cliff” (I think), but still not sure we were in the right spot - it was quite overgrown near the road & seemed like private property on a dead end street. We ended up going to mastodon state park instead, but my boys were disappointed not to get to look for fossils. Any tips on best place to park near this site to safely & legally fossil hunt?! Any tips are appreciated!

During my third trip to a Fern Glen outcropping, I came across this specimen. It doesn't really resemble anything else I've found there. Luckily the "spines" are pretty sturdy, and I didn't break any of them when digging it out. Any ideas?

This specimen was taken from a Mississippian deposit in Jefferson county, Missouri. All of the other items I found were easily identifiable, but I have no idea what this is. The "skirt" is interesting. I'm not sure if the material behind the skirt is solid, or if it is just a fragile membrane. I didn't post a photo of the bottom because it is just dirt/rock.

Prepping a Fern Glen rugose (Triplophyllites cliffordanus)
Raistlin posted a topic in Fossil Preparation
First I will say that the number and size of the photos makes it so that uploading directly to the forum more of a job than I'm ready for at this time. Actually I had to divide the prep photos into two different links because there were too many to upload on one album. Secondly and more importantly big thank you to @piranha for linking me to the identification of my rugose coral. From the PDF linked I have came to the conclusion that the rugose coral is a Zaphrentis cliffordana. It's truly the only real match of the corals listed. Now the prep. I started with a Dremel engraver with a very small tip (I forgot the size I've had it for years). I took matrix away and away and away. After several hours I started to hit it lightly with a metal pick (think of a straight dental pick). I also took the Dremel engraver and started to work away my prep channels/lines as best I could making the stone around the coral smooth to the touch. Doing this also allowed for some of the natural stone and other fossils in the matrix to show up. Next comes something I've never tried and maybe others haven't either. I started to scrape, cut, and whittle away at the smooth matrix with a pocket knife (a sharp one) this made it really smooth to the touch and the stone was fairly easy to do this to. Doing this really made the stone and what makes it up stand out (sort of like polishing it without the shine). After all that I hit the fossil with the an air blast to get rid of all the loose dust and matrix. I then gave it a good soak in peroxide and hit it with a nylon brush and a tooth brush. After everything was dry I coated the fossil side of the matrix with a matte finish clear coat. This gives the matrix and fossil a slightly wet appearance making it stand out way more than the normal dry stone. Here is part one of the prep. The first photo was taken after just a few strokes of the Dremel engraver. https://imgur.com/a/KAiPDDW Here is the second part when I started to smooth the matrix around the fossil. https://imgur.com/a/rJHM1ZK Sorry I didn't do step by step photo upload but I'm not that good at editing photos and my phone which I used this round took too large of photos and there were way too many (around 60 photos nearly). I at the very least was hoping to get the before and after photos uploaded but they were too big too. -
Fern Glen rugose corals. I need some help/information.
Raistlin posted a topic in General Fossil Discussion
Does anyone have any information on the roguse corals found at the Fern Glen formation? I can only find one but the ones I have found there look nothing like the one in the photos. Mine all look like the "normal" tornado shapes. The Fern Glen is Mississippian. Here is the photos I'm talking about Amplexus sp. http://www.lakeneosho.org/Miss48.html I just did a prep on one (maybe my best prep yet) it's just a common and not even a good specimen, but I tried some different techniques. I'll post it tomorrow after everything dries and sets in. It turned out better than I thought but I will welcome critiques.- 2 replies
