  2. My Fossil Room is a Mess

    Fish from previous picture. Hard to see in the light.
  3. My Fossil Room is a Mess

    Parts of a Jurassic sturgeon
  4. Squalicorax advent calendar

    Another day in the Lower Campanian. Squalicorax yangaensis Woodbury Formation Lower Campanian Cooper River, Cherry Hill, Camden County, New Jersey, United States of America See you guys tomorrow, Sander
  5. My Fossil Room is a Mess

    Triassic shark spine. Poor quality. From Penarth
  6. My Fossil Room is a Mess

    16 inch ammonite destined for Robin Hoods Bay coastguard centre when I finally get around to popping over,
  7. My Fossil Room is a Mess

    Thanks. You find lots of bits but that’s our biggest yet
  8. My Fossil Room is a Mess

    Thanks. I’ll be searching through Triassic stuff soon
  9. My Fossil Room is a Mess

    You’re welcome. I’ll keep them coming
  10. My Fossil Room is a Mess

    Ha. You’ll have to show yours.
  11. Stomach contents or not?

    Let me add you periodically see digested theropod teeth for sale. Most are just poorly preserved ones.
  12. Small Claw

    Definitely no barracuda tooth--but if that might have been what motivated you to keep it rather than toss it back, it was a good thing. I found a tiny piece of Petrochirus yesterday while picking some micro-matrix (a great was to pass the time while not out and about). I fairly regularly encounter dactyls (fingers) from the chela (claw/pincher) while picking micro-matrix but less often spot them while out in the river with a sifting screen. Does not match my concept of a tortoise leg spur (osteoderm) as they are solid and have a distinctive constriction at the base. The shape, surface texture (and hollowness) do look about right for a Petrochirus dactyl. I'd be interested to hear what Roger has to say. He may be harder to get a hold of at the moment but we eagerly await his opinion here. In the meantime: http://www.thefossilforum.com/index.php?/topic/72288-crab-claw-from-peace-river/ https://www.agefotostock.com/age/en/Stock-Images/Rights-Managed/AAM-AAES101370 Cheers. -Ken
  13. eocene mammal skull from suthwest France

    I would never have guessed that was hidden away in the rock. Wow! Nice work!
  14. Electric Hand Chisel

    What about something like a Dremel engraver or one of the generic versions? I have recently purchased a generic version which works rather well, for about half the price. They are loud and you need to give your hand a rest every few minutes, but they are inexpensive (for when they break) and the tips are replaceable. https://www.amazon.com/Dremel-290-01-Stroke-Engraver-Template/dp/B0000302YN
  15. 2020 Ontario Trilobite Hunting

    Not me. This is exactly the type of detail I like to know so that i can build up pictures of the site and paleoenvironment in my head. And then I compare with sites of roughly the same age that I've encountered. Reef formation is fascinating. The stromatoporoid reefs always interest me too.
  16. Maybe fossil

    I agree that it is not a fossil. I’m not sure what it is, but it’s very neat. I think @FranzBernhard has some good suggestions. @ynot may also have an idea the next time he pops in.

    Very true! Believe it or not, the rock itself is actually not that hard. It fractures fairly easily along various planes/joints. The whole thing was a massive reef knoll/bioherm, so the only bedding planes occur in pockets or outside the knoll. It is also very vuggy in spots, and almost all of it was subject to serious diagenesis in the form of remineralization and the presence of cementum (which also, sadly, accounts for more steinkerns than actual shell material of the gastros and nautiloids). Some very neat crystal growth in the vugs, though! For the most part, there is a lot of crinoid packstone in all of this -- and only individual bits, never really stems or even calyxes. The very top of the bioherm is capped with stromatoporoids, and was subject to a bit of occasional subaerial exposure. The very bottom is the genesis of the reefal complex with builders, then binders, and then bafflers (ok, now all of this is likely more than anyone might ever want to know about this stuff ).

  19. Pennsylvanian Fish of Illinois

    I love the patterns on this sort of tooth plates. Lovely.
  20. 2020 Ontario Trilobite Hunting

    Nice finds. That rock looks pretty hard. Showstoppers? Not likely at the moment as all the shows have been stopped already.
  21. New Mazon Creek Collection

    You are welcome! I'm not a detective, but I am a librarian.
  22. Fish tooth?

    Reminds me a little bit of barracuda , not that it is barracuda, but a lot of fish has short spikey teeth in the ancient oceans of Kansas. I do not think it is actually cuda, because cuda has a distinctive shape obvious to experienced Florida fossil hunters, but there were a lot of other Eocene fish to qualify
  23. 2020 Ontario Trilobite Hunting

    The profusion of Crassiproetus bits was getting ridiculous. I kept setting them aside (taking only one or two of the nicest ones -- not that I need more) until it was just getting silly. I did pick up this neat nautiloid steinkern with what I assume would have been some moulted Crassiproetus glabella having washed into the void. I am reminded of some fascinating papers I've read of trilobites being found in nautiloid chambers. This is not an instance of a bug looking for temporary shelter, but likely a kind of sediment in-wash of an abandoned shell.
  24. 2020 Ontario Trilobite Hunting

    Spent the afternoon in Formosa yesterday. No showstoppers, but some neat stuff regardless. The little mountain has been changed forever now that I've come with serious tools. Starting this off with non-trilobite stuff. A good assortment of steinkerns and fossils. Platycerids, nautiloids, bivalves, etc. In the group shot, one of those bivalve steinkerns in the middle has both valves. The large gastropod with the low turret on the right was a neat find, and a healthy size (also shown in hand). That big brach in hand has original shell and both valves. The tiny pair is a high-spired gastro with a tiny rostroconch friend. Deb found the wee rostro. I didn't keep some of the larger nautiloids as I already have a bunch.
  25. Don, Sorry, no I was not and am not referring to ROM. I had a seed pod Bonanzacarpum sprungerorum confirmed back in mid January and offered it to a (USA) Natural History Museum as a donation on that day. Long before coronavirus hit the spotlight. It was immediately accepted with paperwork to follow. After four follow-ups with "documentation is on it's way" and never received, I put it back in my display cabinet. As of yesterday I still have not received anything. I didn't realize donations were so difficult. After all this covid19 has passed, I will attempt to donate it to another organization. Maybe I'll have better luck next time.
  26. Hexagonal shapes unexplained

    There are outcrops of the Ordovician Montoya Formation in some of the mountains in that area. It is the only Formation in the area that has favositid corals. The Montoya has a diverse coral fauna, including several genera and species of favositid corals. There is a New Mexico Bureau of Mines and Mineral Resources Memoir by Rousseau Flower that treats the corals. Unfortunately good thin sections are needed to ID these corals as you need to see the internal structure. Nice find! Don
  27. My Fossil Room is a Mess

    Very nice. Love the belemnite battlefield.
