  1. Past hour
  2. I sent another email asking for it.
  3. Hunting Rivers or Creeks?

    The fact that the fossils are hidden from view in submerged gravel is a disadvantage to drive-by thrill seekers, but an advantage to hard working, patient collectors willing to put in valiant effort.
  4. Cephalopods of the twin cities

    Done. Is it OK now? Don
  5. Though I should note I am not sure how similar in structure they are. I think there may also be members of Heterodontus whose spines are not venomous. I know Horn and Port Jackson sharks are but I don’t know about the rest of that order.
  6. Yes. Squalidae have dorsal fin spines and most are not venomous as far as I know. The Spiny Dogfish is venomous and that is the only one I can say I know is venomous. There could be others as it is a large family
  7. Recent Centrophoros squalosus has a spine on the dorsal fin, but I don’t think it’s poisonous. Squalus acanthias also has them.They may not look like Xenacanthid’s. I can do a pic if you are interested in but actualy it is the night. Coco
  8. Can someone help with my IDs on these please?

    I can't find much about this online, could you give me some more information please if possible?
  9. Are there any spines similar in structure on extant species known NOT to be venomous?
  10. Can someone help with my IDs on these please?

    Thank you!
  11. Last year I discovered a baleen whale fossil along the cliffs of Calvert cliffs park. Tomorrow it will be getting excavated. However I broke my leg just before Christmas so I am looking to see if anyone can video the excavation for me as I cannot attend. I’m hoping to get a video and some good pictures I can share on here. Please feel free to message me as I’m anxious to see the excavation process. I just wish I had better luck so I could attend and assist in the excavation of what I found. Anyone willing to help is super appreciated !!! Thank you
  12. No way! I'm pretty sure I know the piece, is it like 10ish ft tall (rough estimate from memory)? It's a pretty amazing fossil, and I think just the fact it's on display speaks for itself. Next time I visit I'll be sure to check it out again/look at it in greater detail. Thanks!
  13. So I guess that the general consensus is that the claim of venomous spines on Xenacanthid sharks is erroneous and impossible to actually prove or disprove. My thought is that this belief stemmed from the superficial resemblance of these spines to those of extant sharks and rays, which are venomous. The belief seems pretty widespread though, so hopefully others who are curious find this thread and have their questions at least somewhat answered. Thank you all again for the informative replies.
  14. No problem at all! I definite recommend you visit, the mammalian and reptile sections of the new hall are also amazing, and if it's your first time visiting the museum, there's a modern mammal hall, and a marine hall with some marine reptile stuff. Upstairs there's an entire wing dedicated to geology as well (make sure you check out the florescent mineral section, I used to live near the Franklin mine where a lot of the specimens on display are from). Have a good rest of your week!
  15. Manual Preparation: A Novice Guide

    Fantastic! Thank you!! I've been hestitant to really do any kind of prep aside from some hammer and chisel.....this is actually making me want to try my hand at some detail work! Thank you!!
  16. Pierre shale fossil finding

    Finding new places to explore is half the fun of collecting fossils. Nice detective work. I don't know if FossilDAWG is onto something or not, but I have found hundreds of concretions that are full of small clams that may or may not be the seep genus Nymph..etc. In any case these areas can be good for ammonites. The best way to prep these nice little snails is with a microscope and a small air scribe.
  17. Asking for help to Identify Leg Bones

    1-3 are bovid metapodials. 4 is horse metapodial. 5 is a deer metapodial.
  18. Cephalopods of the twin cities

    Dismiss the post about actinoceras its 100% wrong.
  19. JooJ

    where you stumble, there lies a treasure

  20. Mille lacs

    Well actually theres plenty of fossils. Theres a fossil park in NE Minnesota that have createous fossils. Then corals have been found in scattered locations, usually from glacial deposits since lava can't 100% destroy large reefs of coral. Sandstone is also found along north shore thou fossils are not found there.

  24. Myths of fossiling Twin Cities

    True. I hadn't does Minnesota river area. Beside I'm talking about the twin cities area not greater Minnesota. And yes its dolomitic limestone my mistake. I keep getting dolomite and limestone confused. Been trying to catch up with my rock knowledge mainly by collecting local glacier rocks.
  25. Help with ID of fish fossil

    Rhacolepis buccalis from the Early Cretaceous (Santana Formation) of Brazil. Definitely not from New Jersey. Nice fish!
