  1. I thought it would be cool to make a poster of my fossil of the month for March 2018. Markus took some great pics after he prepped it and I just took them and made this horizontal poster. I might put a heading on it or not. Let me know the one you like the most. Thanks Mikey
  2. Possible Crinoid or Sea Pen?

    I found this a few years ago at my camp near Munising, MI. I find a lot of fossilized corals, trilobites, and bryozoan there. I am going through my fossils and trying to label them, and I noticed this odd one. I am thinking it is a crinoid or a sea pen, but I am not sure.
  3. Hi everyone this is matthew again saturday I went to the fossil and gem show in hamburg N.Y. and got 3 fossils one of them is a crinoid flower fossil and one of them is a strait shelled ammonite and one of them is a fossil that looks like a point.
  4. At our favorite auction site, new collectors can easily be impressed with a fossil crinoid like this: Even more so as it is a large (470mm X 260mm ), gorgeous fossil for display and highly impressive. So, I am posting this here as a alert to new collectors, who often for being inexperienced, end up believing that a ballot US $ 25 Dollars really can exist... First of all, it's interesting to know that in addition to the seller offers entirely free shipping to the world, it's also important that I explain to you that originally this fossil Crinoid is not white! The problem here is that a strange mass (I highlighted it in pink), is uniting dozens of broken crinoids mounted on a fake matriz plate, as if they were whole crinoids, and to disguise this great puzzle, they simply painted everything in white! And now, problem solved, for hardly a new collector would notice in this small but great detail! Look: Any more problems? Yes! All of these areas that I circled in pink are 100% sculpted by human hands! Look: Now you can compare of Guizhou, what is carved and what is 100% real, which is painted white and the one that has original coloration: I apologize for making your dream evaporate, of placing a Guizhou crinoid next to a Guizhou keichousaurus on your shelf... Do you intend to buy from another seller? No problem! On our favorite auction site there are other vendors who also market Guizhou fossil crinoids! See this one! 100% original coloring, and no sculpture made by human hands here! Look: Beautiful and amazing, is not it? 100% original coloring! But the only problem here is that you are taking to your home a new mosaic puzzle: And under the pretext of "pyritization" and "calcite," you will take entirely free to your home, a strange white mass of glue with something unidentified; But if you also did not like this, no problem, there are more choices of Guizhou crinoids on our favorite auction site: Oooooopppsss! Is gone away this option too! At our favorite auction site you will probably notice that a 100% genuine Guizhou crinoid fossil is nothing perfect, it may not be as gorgeous and complete: But at least now you know the difference between one thing and another thing!
  5. Could use some help on these 0.5cm - 1cm invertebrate(?) conical spines in the well known Salem Limestone, a marine limestone of the American Midcontinent. They appear to be solid calcite but do not quite match up with the shapes of crinoid spines and echinoid spines that I know from the Mississippian. I have looked at umpteen Salem Limestone samples but have seen these spines at only one small locality. Any insights appreciated! but please provide your reasoning or evidence.
  6. Crinoid and Conretion from Guizhou

    This is a crinoid fossil from Guizhou, it is attached to a gigantic concretion. Do you think there is a fossil inside the concretion? Other than breaking it apart, any other possible way to check if there is a fossil inside the concretion?

  14. Crinoid stem segments exposed by February rains, from the Devonian, Keyser Formation limestone, in South Central Pennsylvania.
  15. Some of the fossils I found when collecting with my nephew Joey and my Girlfriend Paula during February recess. Joey is my good luck charm. The rare crinoid with an attached gastropod (snail) is a first for me. It was nice to get out and do some hunting with my crew. Im getting the crinoid prepped and will post pics to the thread when that happens. Thanks Mikey
  16. Waldron mystery fossil

    I picked up this weird fossil at the quarry in St Paul, IN last year, found as is: on the ground, split in half. It seems to be studded with crinoid holdfasts and bryozoan encrustations. Any ideas what it is? Under magnification it is a beautiful specimen. Also, I'm tempted to sand/polish one of the halves to possibly bring out some details. Would this be advisable? Thanks for any help.
  17. Crinoid?

    I went looking the other day and found these star shaped Crinoids. This rock is full of them It was located in the twins peaks limestone group of the Jurassic time. I believe it is from the species C. Pentacrinus. Is this correct?
  18. Crinoid?

    Is there anyone who would possibly agree that this fossil might not be from a crinoid? The dimensions are about 3cm long and up to 2cm wide. After viewing numerous fossils of this sort, in a Leonardian formation, they are rarely, if ever, found in groups of more than three, and the occurrences always look the same as in the images attached. If there is no doubt that it is a crinoid, would you please post which might show a convincing likeness? Other than curled arm or columnal (stem disc) I am at a loss and by far much less than a novice paleontologist. Thanks for any help and forgive me if my terminology is not spot on.
  19. Iowa lawmakers: After 500 million years, crinoid fossils deserve recognition. William Petroski, Des Moines register, Jan. 19, 2018 https://www.desmoinesregister.com/story/news/politics/2018/01/19/iowa-state-fossil-crinoid/1047564001/ Yours, Paul H.
  20. Crinoid IDs

    Today while driving around I saw a coin store that also sold fossils, so I thought that I would stop in and look around. Whenever I go into a little store I don’t just like to browse around without out purchasing something to help the small business owner. So I decided to purchase this little piece that was ID’d as Sarcocrinus granilineus from Crawfordsvile, Indiana. The piece appears to be original and nothing added, but I am not sure of the name. I am not a real crinoid collector, but I could not find this species on the internet. In addition, to me the 2 caylx look different to each other.
  21. Crinoid stem with side arm.jpg

    From the album MY FOSSIL Collection - Dpaul7

    Crinoid stem with side arm SITE LOCATION: Harpersville Formation, Coleman County, Texas, USA TIME PERIOD: Pennsylvanian Period (299-323 Million Years ago) Data: A crinoid stem in matrix, with other stem sections. Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form". They live in both shallow water and in depths as great as 9,000 meters (30,000 ft). Those crinoids which in their adult form are attached to the sea bottom by a stalk are commonly called sea lilies. The unstalked forms are called feather stars or comatulids. Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults. There are only about 600 extant crinoid species, but they were much more abundant and diverse in the past. Some thick limestone beds dating to the mid- to late-Paleozoic are almost entirely made up of disarticulated crinoid fragments. Kingdom: Animalia Phylum: Echinodermata Class: Cridoidea
  22. Please identify fossil, seed or rock

    This was found in a riverbed in Indiana three decades ago. I have yet to figure out exactly what it might be. A gem show expert said it was a Crinoid Sea Lilly but it does not really match Sea Lilly photos posted on line. It is 4 1/2” long, 7” around and weighs 320 grams. Thank you so much for your input!
  23. Is this a fossil

    I am wondering if this is a fossil of a crinoid of some type. I found this is a creek in NE Oklahoma. I believe that most stuff is from the Devonian and Carboniferous time. It is in the harder dense material with a conglomerate of shells and other things on top .
  24. Date my sherds from ichnofossils?

    I thought I was joining my husband in his kingdom of Pareidolia when I thought there were mold or trace fossils, which I now know as ichnofossils, on some of my sherds from time to time. I have no idea how long it takes for such fossils to form, and I often don't have a guess as to how old a sherd might be or how long it could have been in the ground or water, but I am changing my mind. I see fossils on my sherds and I'm not crazy (well....)! I hope these examples are photographed well enough for you to see them, too. I'm very curious if this is common and if I can date the sherds according to the fossils.
  25. crinoid calyx

    good evening this came from a creek in travis county with plenty of volcanic ash fossils and mollusks. Any iformation appreciated
