  1. Well, it's hot in Texas in August. 107 is the forecast for Saturday. Soooo...I'm hunting at home! Still having fun with the micro matrix stuff! This time, it's from Mineral Wells, TX. While i have been there a variety of times and found lots of great stuff, I never looked quite THIS close to find fossils! So a pound of washed matrix and my microscope camera landed me a few neat things. I was hoping for a whole Trilobite (which I have found three small ones at Mineral Wells) no full trilos this time, but some trilo bits! But my favorite things are the Crinoid parts...the geometric architectural elements of crinoids simply amaze me. So here are my favorite Mineral Wells Minis. All of these are 1/8 inch and smaller. Echinoid Plates and Spines: (Big one is 1/8 inch) Trilobite Bits: Crinoid fragments (stems, calyx, bulb, and arm structures) I am simply amazed by the geometry of these! And a couple of tiny gastropods: I"m not completely sure what this is...I assume a bit of crinoid, but it has a different texture than the others.
  2. Multiple Petalodus Teeth Fragments

    From the album Chondrichthians

    A few Petalodus teeth fragments I have found
  3. Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale Specimen 1: Fish Coprolite? 1.8cm (nodule size) Specimen 2: Coprolite? 2cm (nodule size) Specimen 3: Fish Mandible? (2.6cm) Specimen 4: Coprolite or Maybe Braincase (I think it is very unlikely that it is) 2.8cm Nodule size 1.5cm (fossil size) Specimen 5: (2.9cm) Note: The placement of the fossilized material might be wrong as this was one of my first nodules and the fossilized material fell out. I recovered what I could. (Opened roughly 2 months ago) Specimen 6: Tessellated Cartilage with some Skin impressions ? (2.5cm) Specimine 7: Fish material? Thank you for reading and viewing this, I hope I can better understand these images so I can use them as references in the future!
  4. Location: Missouri Geological time period: Pennsylvanian Formation: Muncie creek shale I believe it is some sort of cartilage or fish material but I honestly have no clue.
  5. Deltodus sp. Tooth (Top View)

    From the album Chondrichthians

    Any Id's or corrections are welcomed! Correct id by Jackson g
  6. Petalodus sp. Tooth

    From the album Chondrichthians

    Roughly 50 mm in size!
  7. Hamiltonichthys Tooth Close Up

    From the album Chondrichthians

    Specimen is 7mm in size. I was told this could be Hamiltonichthys after posting it to fossilId
  8. Unidentified Possibly Cochliodus

    From the album Chondrichthians

    One of my teeth that I really want to identify. It was mentioned it could be a broken or partial Petalodont crown minus the root. 13cm in size
  9. Assumed Orodus Tooth

    From the album Chondrichthians

    I assumed due to there being multiple guesses on the fossilId section and this one best fit the description It is roughly 7mm in size It could also be a juvenile of a Petalodont but that is my theory
  10. Caseodus Tooth

    From the album Chondrichthians

    I believe this to be a Caseodus tooth but if this is the wrong, possible id's are welcomed!
  11. Concretion 13: Campodus tooth

    From the album Muncie Creek Shale Nodules

    This is the most detailed side of the concretion that contains the Campodus tooth
  12. Concretion 8: Possibly Gular Bone

    From the album Muncie Creek Shale Nodules

    Close up picture, identifications are welcomed!
  13. Concretion 7: Skin impression?

    From the album Muncie Creek Shale Nodules

    I believe the dark brown may indeed be skin while the blue part is cartilage.
  14. Concretion 6: Fish material

    From the album Muncie Creek Shale Nodules

    My best guess is fish material or crustacean material
  15. Concretion 5: Fish Cartilage

    From the album Muncie Creek Shale Nodules

    One of my larger concretions and personal favorites
  16. Concretion 4: Unidentified

    From the album Muncie Creek Shale Nodules

    I assume this is some sort of bone either from a fish or some sort of other specimen. It could be a spine of some sort but I am extremely doubtful
  17. From the album Muncie Creek Shale Nodules

    This concretion came out in multiple parts and I was able to salvage the tip. I will restore this specimen and prep it in the future!
  18. From the album Muncie Creek Shale Nodules

    The second half of the cartilage pterygiophores When breaking the concretion most of the internal structure was unfortunately damaged
  19. I know some of you find very complete nautiloids that are much larger but here in Texas they are often smaller and fragmentary, though the pieces can be well preserved and easy to extract from the loose shale of the Graham Formation at Jacksboro Texas. I had many fragments separated into boxes labeled "Pseudorthoceras" and "Mooreoceras" for smaller and larger segments respectively. Then I saw a paper that invalidated the latter genus, Revision of Some Common Carboniferous Genera of North American Orthocerid Nautiloids, Kröger & Mapes 2005, which made all of my specimens Pseudorthoceras knoxenses. This got me wondering what these creatures might have looked like whole so I started to gather a few fragments that might fit together in a continuous shell, including a piece with the protoconch and one with part of the body chamber. The result had one empty space which I filled with a clay reconstruction, then made a plaster mold from which I poured a plaster cast to fill the gap. I used super glue to hold everything together so I could take it apart with acetone if I wanted too. It may make a good display fossil for our table at local events though so I'll probably donate it to the Dallas Paleontological Society. The second section from the large end is the fake part. The rest are all genuine fossils from the same site but collected over several years, so not even considered to be associated. I'm pretty sure they are all the same species though. The whole thing is 38cm long and came out fairly straight considering what I had to work with..
  20. Weird Fossil ( Missouri )

    Location is in Missouri The area is dated to the Pennsylvanian Formation: Probably apart of the Raytown limestone member Found this weird fossil on my latest fossil hunting trip, I personally believe it to be some sort of Amminoid since the pattern seems to extend away from the shell and not towards it, but I have only found Nautiloids in the area ( Only 2 spiral shaped specimens that do not look like this and 3 cone shaped.) If anyone can Identify if this is a an Ammonoid or something else I would love to know more! the middle Section with the weird ball like pattern in the middle and what I assume are gas chambers around it
