Hi all, Recently going through some of my Stark Shale material and prepping some of it and this little specimen has me wondering if it’s a tooth. It’s probably pareidolia but the lip at the bottom appears to have a sort of smoothness to it unlike the two protrusions. I'm not sure if the honeycombed structure is bone or cartilage but I’m trying to decide if I should prep it any further and any ideas or thoughts would be appreciated. @Petalodus12 @connorp 1. 2. 3. Thanks!

Been cleaning conodonts when I came across this in Pennsylvanian Stark Shale member between Winterset and Bethany Falls limestone in Kansas City. took me almost as long to get the lighting and focus in perspective as it did to clean it!. Is it reasonable to say this is a fin rather than a scale?......and any thoughts on taxa or even species? As usual, thanks all!! Bone

Listracanthus denticle?, then another or different altogether?
Bonehunter posted a topic in Fossil ID
Hi all! Well, now I am into splitting shale finding conodonts and will post my best ones soon, but I've come across several of these which are comparable to images in the forum and on references to Listracanthus denticles?. It was found in Pennsylvanian Stark shale member in Kansas City two days ago. Is that a fair i.d.? They're are all very similar, but I've found this as well- a "carbonized" film with a structure that doesn't have straight lines, but somewhat veinated? Very difficult to get pics of that so provided several in different light. The first is 27mm long and the black piece is only about 2-3mm at most. Am I on the right track on the first, and any ideas on the second? same, fish fin, plant impression/other? thanks! Bone Then here's the other one- found in a different slab of shale but same level- the bottom "ridge" appears to diverge in the first couple pictures, then there appears to be divergence in the middle in the darker pics. Any thoughts welcomed! Bone- 4 replies

Can someone help me identify the item that is with these two conodonts? My guess is a fish scale. This is from the Stark Shale, Dennis Formation, Kansas City Group. The conodonts are 2mm or so and the specimen is 7mm. I am intrigued by the surface of the "shell" which is a bit crab-like (I'm not saying I think it is crab, but that the item's shell has that kind of texture). I've included pictures of both the item and its external mold on the other half of the split shale. Let me know what you think. Russ

My curiosity has gotten the best of me, so I am submitting this crushed specimen for an ID even though it may be unidentifiable. The item is roughly circular and about 15mm in diameter. It split with the shale and the two smaller pieces of shale contain most of one half; the other half is seem on the larger piece of shale that is split down the middle (see the picture with the ruler). What intreagues me most is the shell-like material. This specimen is from the Stark shale of the Kansas City group in the Pennsylvanian subsystem. Any ID help will be appreciated.

As I have continued to examine the conodonts I'm finding in Stark Shale Member material (Kansas City Group, Pennsylvanian), I've found what appears to be a group of conodont fragments. What does this look like to you all? Russ

I found this item in shale from the Stark Shale Member, Kansas City Group of the Pennsylvanian. Photos are of either of the halves of the specimen. The specimen is about 2 cm long. I would appreciate ID help. The only thought I had was that it seems to be flora and that the "stem" looks similar in appearance to Cordaites. Thanks, Russ

A couple of months ago I collected a small bucket of shale from the Stark Shale Member in the Dennis Formation of the Kansas City Group. My purpose was to find conodonts. Today, I had a chance to look at the shale and I found a conodont this afternoon--the first one I've ever found . I was able to extract this with a small needle in a pen vise. I took the pictures with a Celestron MicroCapture Pro. For any locals that are interested, this came from the Firemen's Memorial. Russ
