connorp Posted June 3, 2020 Author Share Posted June 3, 2020 I have been saving all my black shale pieces until I've gone over the with my microscope at least twice. Good thing because I found other side stored away – must have missed it the first time. 7 Link to comment Share on other sites More sharing options...

This might be important. An articulated conodont apparatus is relatively rare. I'm happy to recommend experts if you're willing to donate this to science. 6 Link to comment Share on other sites More sharing options...

Would definitely be worth having a researcher examine it. 2 Link to comment Share on other sites More sharing options...

Very nice. Seems like a lot of pieces for one animal. I wonder if this is a coprolite with many individuals. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5346137/ 1 My goal is to leave no stone or fossil unturned.

These seem to be in partial articulation too. 4 Link to comment Share on other sites More sharing options...

connorp Posted June 10, 2020 Author Share Posted June 10, 2020 A couple new additions tonight. This partial Deltoptychius (armigerus?) tooth plate was finally freed from limestone last night. The underside was all that was exposed when I found it, and it took almost two weeks of vinegar baths to remove. It is very similar to one I posted earlier. I am very happy to finally have some iconic Petrodus denticles to add to my collection. Like the Listracanthus denticles I've posted, these were collected from the Peabody Coal Co. Pit 14 in the 80's or 90's. 8 Link to comment Share on other sites More sharing options...
Titan Posted June 28, 2020 Share Posted June 28, 2020 @connorpThis is an amazing gallery of specimens. You've helped me ID several of my recent finds and I just wanted to say thanks for sharing all these! 1 Link to comment Share on other sites More sharing options...
connorp Posted June 28, 2020 Author Share Posted June 28, 2020 @Titan Glad you found these posts helpful, it was definitely a hope of mine. This was not a find but a gift from family. I received it a while ago but just finished exposing the left half (in the picture below) as the concretion split weirdly on two different planes. It is Palaeoxyris appendiculatum, a chondrichthyan egg case from the Mazon Creek deposits. I would guess this came from the river itself but that information was not provided. 11 Link to comment Share on other sites More sharing options...
deutscheben Posted June 28, 2020 Share Posted June 28, 2020 Nice, and nicely prepped! I just collected some black shale with fish bits from Vermilion County today and thought of your finds from this thread. 1 Link to comment Share on other sites More sharing options...

connorp Posted July 4, 2020 Author Share Posted July 4, 2020 The very first specimens I posted in this thread were three different specimens of fish regurgitant from the Mecca Quarry Shale. I never looked at them under my microscope until today, and the detail is quite nice. Most of what I can ID are the rhomboidal palaeoniscoid scales of which there are many, so the bone fragments are probably palaeoniscoid as well. Typical masses of bone fragments with a couple nicely preserved scales. Two spine-like objects, perhaps acanthodian fin spines. What looks like a small jaw fragment. It's about 1cm long. 11 Link to comment Share on other sites More sharing options...
jdp Posted July 4, 2020 Share Posted July 4, 2020 Definitely a jaw fragment. With a little work, you might be able to get an ID on that fish. 2 Link to comment Share on other sites More sharing options...

connorp Posted July 14, 2020 Author Share Posted July 14, 2020 This was a heartbreaker. I believe this Cladodus tooth was both complete and intact, but it was preserved perpendicular to the very flat face of a several hundred pound block of limestone. It ended up shattering after almost an hour of trying to extract it, and this was what I was able to recover. It's a quite large tooth compared to the others I've found. 9 Link to comment Share on other sites More sharing options...
deutscheben Posted July 15, 2020 Share Posted July 15, 2020 Ah shoot! Same thing happened with my biggest cladodont tooth from this site, I tried to smash it out of a giant boulder and wound up with just the root and base of the cusps- it’s nice that you were able to piece back together the majority of the lateral cusps. 1 Link to comment Share on other sites More sharing options...
connorp Posted July 16, 2020 Author Share Posted July 16, 2020 This super small partial cladodont tooth popped out in a vinegar bath today. It's probably a millimeter wide. I do not recognize it. 5 Link to comment Share on other sites More sharing options...

Tomasz Posted August 15, 2020 Share Posted August 15, 2020 Very nice and interesting material. Conodont articulated apparatus is extremely rare. First time I see like this one. Always love to see fossils from Linton. Best, Tom 2 Link to comment Share on other sites More sharing options...
