  1. Help with large Carboniferous fish tooth

    Hey guys. I'm looking for some help with this large mystery fish tooth from the late Carboniferous of Illinois. The closest match i can find is from the Devonian lobed finned fish Hyneria. But this is late Carboniferous almost Permian. Another contender just based on size is the Rhizodont. But it's not rounded. This tooth flattens out to two cutting edges that are very sharp. It honestly reminds me of a Barracuda tooth. This broken tooth measures about 20mm, but would have most likey been around 30mm if complete. It is associated with a Megalichthys scale and Orthanthus teeth. Any thoughts?
  2. Our new Shark Education Displays

    Pictures first, full descriptions will follow Paleozoic Sharks and “Sharks”
  3. This head spine has just reappeared in my collection - I must have found it about 20 years ago in Linton. Is that an Orthacanthus or Xenacanthus head spine? The length is about 8 cm / 3". Thanks Thomas
  4. Megalichthys of Illinois

    Yesterday i found a very rare Megalichthys jaw with dozens of teeth still attached in the Carboniferous of Illinois, USA. This is possibly the best known example of this fish found in Illinois. Not sure yet though. I still need to do more research. You can see four larger teeth in cross-section on the matrix waiting to be prepped out. Then there are smaller teeth in-between the larger ones, maybe 4× smaller. I also found several large scales. I'll attach the best one. All of this material still needs a proper repair and prep job. The preservation on this material is just stunning. I'm not sure it could get much better. These bone fragments and scales are often found with Orthacanthus teeth and Calamites. So it gives us such a beautiful snapshot of the environment at the time. Just awesome! Happy hunting
  5. Hi everyone I think I just found a new hobby With my latest fossil delivery I recieved quite a lot of microfossils & matrix vials as the world of microfossils was something that I have been long interested in. So a 2 weeks ago I finally ordered my first microfossils for which I reserved a special drawer in my archive cabinet. So here is a recapp of what I all got: 3 vials of permian material from Waurika, Oklahoma 1 vial of permian material from The red beds of Archer County, Texas 1 small vial of Conodont rich Mississippian material from the Chappel Limestone formation, Texas 1 small vial of Cretaceous Lower Gault Clay, East Wear bay, Folkestone, Kent, UK A micropalaeontology slide with Jurassic Blue Lias matrix rich in holothurian material. A thin section of an Ostracods filled Elimia snail from the Green River Formation in Wyoming A thin section from the Rhynie chert of Scotland which should contain preserved parts of the plant Aglaophyton major and perhaps even other species. I also got a lot of Bull Canyon micro fossil teeth and 2 cretaceous mammal teeth from Hell Creek In this topic you will be able to follow my path through this newly discovered hobby as I will post my finds and progress Currently I am only working with a clip-on cellphone microscope, but I do plan on getting a professional microscope in the next few months! (Tips are always welcome) So let's put on our Ant-Man suit and explore the microfossil realm So here are some of the first pictures I made of some of the microfossils Starting with the thin slices! Thin slice with Ostracon filled Elimia tenara snail from the Green River Formation, Wyoming Thin slice with Aglaophyton major from Rhynie Chert in Scotland
  6. In the last two weeks i have found two new very promising fossil sites. They are on private land that i have permission to be on. And please don't ask where. There are so many things that i have to leave many behind. I hope i am lucky enough to find something truly amazing from these sites and share them with science and ultimately all of us. I believe this to be the first Orthacanthus sp. specimen ever found in this area of Illinois. It would be pretty neat to add this awesome predator to this fauna. As found: After prep: On the same trip i found a bone block associated with crinoids, a Metacoceras, a shark denticle, possible shark cartilage and what i believe are tetrapod bones. Please feel free and let me know what you guys think about the bones. A deep water environment with tetrapod material???? This strangely shaped bone has a thin outer layer on the "ornamental" end, almost like tooth enamel, but it's not thick enough. Continued..........
  7. Any Permian/Carboniferous shark experts?

    Found this last Sunday. And i can't seem to narrow down who lost it, Xenacanthus or Orthacanthus. To my knowledge neither has been formally described from the location it was found. And, no, i will not say where. I'll simply say LaSalle county, IL. Still not sure if my site is Permian or Carboniferous. I'm 90% convinced it's Carboniferous. Any ID help is much appreicated. I'm leaning more towards Orthacanthus. Sorry, i'll add mm later. As found: After some needle prep:
  8. Hola, soy nuevo aquí, no tengo muy buena ortografía pero intentare redactar lo mejor posible lo que deseo solicitarles, estoy recabando y buscando información sobre animales extintos desde el pre cámbrico hasta el pleistoceno, pues estoy en el proceso de la creación de un libro con ilustraciones, así que si es posible me gustaría que me ayudaran con algunas especies, lo que necesito no es mucho, solo información sobre la especie tipo de cada genero (es decir, su distribución, rango de edad, el espécimen tipo y donde se encontró, etc.) pensé que podrían ayudarme pues en esta página suelen hablar de fósiles y he visto descripciones muy buenas sobre algunos ejemplares, las especies de las que necesito su distribución (época y lugar) son: Orthacanthus milleri, furcacauda fredholmae, furcacauda heintzae, goniatites sphaericus y cyrtoceras minneapolis. He buscado en la base de datos de paleontología pero la información es ambigua.
  9. Some impressions from my private collection of permian fossils, some of them I digged myself, some I changed with other collectors, most of them I prepared myself the permian fossils had been found in Germany, Rhineland - Pallatinate niederkirchen , pdernheim and other locations
