  5. fossil quahog

    This amazing bivalve fossil was a gift. The giver had no info to offer. I am curious about what its origins might be - where/when; about how old it might have been when it died (it is 6 inches across and has several hundred growth ridges); and I would like to understand how fossilization can result in what appears to be a set of perfectly intact valves, complete with so much detail - in other words, the shells are much heavier than living shells would be, what has replaced the calcium bicarbonate to make the shells so much heavier?

    Got it from a friend. This actually should come in one piece and not separated like this. Probably someone split it up so that he/she could see the inside. Probably found in Papua, Indonesia. Please your ID. Thankyou.

  15. Shells from Carniol

    Hi all, Here are a gastropod and a bivalve that I found in Carniol, southeastern France this summer. They are from the "Gargasian", Aptian, Cretaceous. The pictures aren't fantastic, so if needed I can retake them. Thanks in advance, Max #1 A gastropod (surprisingly not a steinkern, but the shell itself!). Preservation is surprisingly good I find for something this old, especially taking into account the fact it's been replaced by pyrite!
  16. Hoploscaphites Spedeni

    Originally the specimen was collected as a concretion from upper Pierre Shale Formation near the lowest level of the Fox Hills Formation. The collection location is Cedar Creek about seven miles south of Glendive, Montana. The Date collected was Oct. 12, 2018. Later, I removed most of the concretion/matrix with diamond blade and bits. Two of the hoploscaphites spedeni were badly crushed and fractured during fossilization and are missing half of shells. During prep, I miscalculated the depth of cutting blade, slightly damaging the middle scaphites.
  17. Scaphite

    I was seven miles south of Glendive; Montana on October 12, 2018; time 1400; exploring a drainage cut into the Pierre Shale Formation while looking for concretions. This scaphites was partly exposed on the surface of a concretion. Later, I removed most of the surrounding matrix.

  23. Is this in Nautilidae?

    Not quite sure what is going on here. In my class we were handed a box of fossils and this was in it. My theory is that its the body of a nautilus. Let me know what your thoughts are.
