  1. 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
  2. Permian Mystery Micro-Chondrichthyes Denticle?

    I was going over some of bits of Permian micro mix from the Neva Formation in Kansas and I found a fossil I had come across in my initial search months ago. I recently looked at a publication on Permian sharks from Russia. I remembered seeing something similar in that publication. It was a monocuspid denticle attributed to Cobelodus and I can not help but wonder if our mystery fossil is chondrichthyes denticle of some sort. Any thoughts ?
  3. Dermal

    When hunting the Peace River, I find some - many Ray dermals of this general form (not quite as pristine as these phosphate mine versions: I have been finding more of the little "buttons" recently, maybe 5-10 a hunting day. When in the productive areas, I find lots of these which I always thought of base plates for attaching bottom of Ray spines. The I ran into something that I have definitely NOT seen previously. Less than the size of a penny. So, what is this and , am I moving back or forward in time comparing this new arrival with older stuff? Usual suspects: @Harry Pristis, @siteseer, @MarcoSr @sixgill pete@Al Dente @cowsharks
  4. Dermal denticles

    Originally from the Midwest, I've been hunting for fossils for about 50 years and found about two "fossilized sea shells". And this was not from a lack of trying! I moved to Summerville, SC about three years ago for a job that included lots of travel. Now that travel is finished and meeting new friends in the area, I have connected with some kids that stumbled onto something that I think is big! Had I grown up in Summerville, I probably would have change my career to paleontology instead of Electrical Engineering. I am amazed at the finds here in my home town. I have taken my wife and kids including their friends to a spot that allows them to find Shark teeth (at a minimum) within 2 minutes of arriving to an area. My dilemma, I would like to know what these type of "dermal denticles" are. For every 20 shark teeth I find, I find one of these. Please refer to the attached pics. Thanks Matt
  5. I'm happy to announce i possibly found the most complete Listracanthus to date. And we may finally get a proper ID for this strange creature. I thought this was regurgitation, but while prepping i believe i ran into cartilage. So i will stop prepping and give this to a professional, or at least let someone with more experience look at this. Unfortunately the rest is in a giant wall of black shale that i won't be able to get back to until next Spring/Summer. The denticles are up to 6mm thick and associated with smaller denticles. I will get more pictures under a scope when i get a chance. God willing i will recover the rest of this creature in 2019. Happy hunting! Possible cartilage

  7. Dermal denticle? Florida

    I found these bad boys everywhere on the beach, but who do they belong to?
  8. Denticle

    Sorry, it's blurry. Hopefully identifiable. It is 3/4" x 1/2". From a late Cretaceous site. Shark or Ray?
  9. I believe this is a partial denticle. Does anyone know what shark or ray it would have belonged to? It was found in a Late Maastrichtian clay in Arkansas.
  10. More from Sacha's Merritt Island micro matrix...anyone out there know what this is? Thanks much!
