Hi all! I have been using my new scope and camera to get some better photographs of conodonts I've recently found in nodules in Pennsylvanian Stark shale between Winterset and Bethany Falls limestone. I have found 4 of these 500-700micron, tooth-like structures-I destroyed several inadvertently removing the "carbonized film". Two of the 3 most recent are not connected to anything, but have a broad base. In the 3rd photo, you can see what appears to be a joint where the "tooth" connects. I am waiting on finer needles to clean this one. Though I call them "teeth", I don't reall

I put this on the microfossil forum as well, but wanted to give a look-see to this intriguing fossil! In my search for conodonts in Pennsylvanian stark shale (between Winterset and Bethany falls limestone) I routinely find concretions/nodules-most are powdery but sometimes i find teeth and other microfossils. Well much to my surprise, upon splitting my thousanth shale, I found a 1cm nodule, and within it, this apparent micro sea urchin-one of two in the nodule. From spine to spine (7:00-1:00) it measures just under 2mm in diameter I am refining my photog techniques with a

Hi All, I'm having trouble identifying what I have here. It's from the Upper Carboniferous - Pennsylvanian Stark shale. It is in a phosphorite nodule. Dimensions are 1.5 inch (3.81 cm) long by 1 inch (2.54 cm) wide. Any ideas would be appreciated. Apologies for the green tint - not sure what that is except for maybe the camera picking up the radiation from this shale layer . Thanks,

Hi Everyone, I’d like to share a few posts on the shales I’ve been hunting recently in Kansas City, Missouri. Long story short – my neighbor is digging a ‘pond’ to China. He has massive equipment from his business and so far he’s dug through about 35 feet (~10.6 M) of material. My land matches his where the dam to the pond is and I saw shale in it which really surprised me since I’ve never found shale on my property. Even in the creeks and gullies. I would also like to say that I have been really inspired by the posts from @connorp and @deutscheben about the shale they find in Illinois

Hi Everyone, I've been working through quite a bit of shale from the Stark member and have a specimen I would like your thoughts on. My brain sees a crustacean claw due to the shape, but I think its more likely that it's a fin. What do ya'll think I have here? Dimensions are 1 cm by 1 cm. My "holding the phone camera to my microscope lens" method isn't working so well, so here's a rough outline of the shape: And the counterpart from the split Thanks,

Hi all! Hope everyone is healthy and Covid free! Been focused on conodonts now and need help with these two- found in Stark shale member between Bethany Falls limestone and Winterset, if I have that correct :), Stark shale for sure though. The first is a beautiful cone I cleaned the base of. There are no additional denticle structures at the base and it doesn't look fractured at the base either. It is just under 1mm in length. I could also be totally wrong and its a fish tooth .The second is also a Stark shale element, but I'm not going to guess what elem

So...while splitting my thousandths shale and looking under the scope, I came across this organism, which appears to have interdigitating teeth?. At least most look interdigitating as opposed? Or , I just dunno. There is also a surrounding imprint on both sides. It was found in Stark shale Kansas City Missouri and is nearly 2mm long. I have two views, and can get the other split side, but this is the best images so far.....ANY thoughts, would be appreciated!....In my very limited (one month :)) experience looking at conodonts, this doesn't appear to be one, (S elements?) but, I've been wrong s

The past month or so I have had a chance to examine some shale from the Stark Shale, Dennis Formation, Kansas City Group. I have found many conodonts and I’ve enjoyed the challenge of taking pictures of them while they are still embedded in the shale. I think I have over 100 specimens now. Below I have posted some of my results. I have tried to identify the element position (P, S, or M) according to Purnell, Donoghue and Aldridge’s “Orientation and Anatomical Notation in Conoodonts,” Journal of Paleontology, 74(1), 2000, pp. 113-122, although I have not distinguished among the various S
