Bonehunter Posted May 8, 2020 Share Posted May 8, 2020 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 1 Link to comment Share on other sites More sharing options...
connorp Posted May 8, 2020 Share Posted May 8, 2020 The first object (the longer pyritized fossil) is definitely Listracanthus. Nice find! The second item does not look like Listracanthus. I would guess it is a paleoniscoid scale, due to its approximate rhomboidal shape. 7 Link to comment Share on other sites More sharing options...

I think you may have just solved a mystery in my Permian poop. Did these critters swim in freshwater?
