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

So.....I was splitting my last piece of Pennsylvanian stark shale member, between Winterset and Bethany Falls limestone from a 2x2' 2" thick piece, I found some cool conodonts, a lot of scolecodonts, and amassing a pile of split shale, when I came upon yet another listracanthus/fish spine, about 5-6cm in length and very slender (2-3mm in width). I have both positive and negative pieces (depicted here). I scan all of these to see the pattern, faint impressions of a wider segment (as seen in photo 6 ), and in this particular specimen noted the shiny black cracks and creases surrounding the fossi

I put this on the general forum as well, but this is probably more appropriate!! 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 newly purchased leica M420,

Good evening all and thanks again for everyone's help and patience with my finds....to that end, here's another one. Stark shale between Winterset and Bethany Falls limestone Pennsylvanian. I'm guessing a fish scale or shark denticle (it appears to be inversely ridged or elevated in deeper layers). I would still like to clean it a little better (the brown-filled divit) but wanted some thoughts prior-it will help me decide how to clean it. Thanks all!! Bone

Again cleaning conodonts in Stark shale member and came upon this- it is elevated about 1-2mm and has what appears to be long "tendrils" or flagella like projections. I hesitate to try to clean this- it looks like a "carbonized" film over what ever it is and I will destroy it if I try....... any thoughts welcomed!!! One of the more unusual fossils, and the only one I've found. Untouched- the lines are not cleaning scratches-exactly how it appeared upon splitting the shale. I don't believe they are fissures/cracking-all of those are straight or parallel that I have seen....interesting eh? Thank

While cleaning conodonts (and the next object to follow this topic), I came across this "imprint"? It isn't a defined shape, but has a very uniform pattern. Thinking fish skin? It looks a lot like the Iniopterygian I found a couple months ago but the "scales" are smaller?.....I'll let ya'll decide or comment!! Thanks!! Bone

So......this stumps me on four levels (not a hard thing to do ) One- it is "sunken" into the shale (Stark Shale between Winterset and Bethany Falls limestone (Pennsylvania); Two-it is cracked ( at the 7th segment/ridge), Three- how do I get this out? and Four- what is it? It does not appear to be a crinoid is my best guess! I sealed it with a very dilute solution of butvar but not sure next steps. Thanks all!! Bone

Looking for conodonts, I found and meticulously cleaned this object-at first I thought insect wing, but then fish scale, then plant, then, nuthin special. Thoughts again appreciated!! What say ye? (Stark shale, between Winterset and Bethany Falls, Pennsylvanian) . Bone

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.

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'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
