  1. Complete Crinoid I'd

    I Found this last week on what I believe some call Michigan mud stone? I do not see visible arms and prefer not to disturb it. I also find no ready history of such finds for this S. W. Michigan County. 2 3/8 in or 62 mm long. Bob
  2. Paulding Ohio Find

    Found this at Paulding Ohio Fossil Park. This is the only one in 5-6 visits to this location. Is this a rare find?
  3. Presumably, having been tumbled along the robustness of the Knob Creek's quartz bearing country rock of the Hoosier National Forest in the Bartlettsville (North Lawrence Co.) IN area, the tip of the Crown (Calyx) of this large Crinoid appears to have been sheered off at some point to give the observer a view (in crossection) of the inside of calyx which reveals absolutely nothing but Silica replacement of all internal parts. This sample is of the Harrodsburg Formation in the Sanders Group, Lower Middle Mississippian Time.
  4. Looks like a crinoid calyx

    Something I found near Coral Falls on east shore at Trout River, NWT. I imagine some of the craters are from the top "arms" and the other is of the stem.
  5. I think I found myself a partial crinoid calyx in some micro matrix. Pennsylvanian period, Jasper Creek fm, Bridgeport, Texas. Measuring just 1.5 cm in length plus another tiny cluster that may be part of another. So I'm posting both on here for more learned opinions. The 2nd one is a bit smaller, measuring only .5 cm in length. I'd like to find an entire calyx (or an entire critter). I seem to have become partial to crinoids for some reason.
  6. Penn Dixie Calyx

    It is very rare that a crinoid calyx is found a Penn Dixie. I was at Penn Yesterday in the blistering heat 39 Celsius and found a small calyx (23mm * 11 mm). I have a suspicion what this is but don't want to taint others before hearing their opinion. This was found in the top of the E. rana trilobite layer in the Windom shale. I prepped it this morning and the preservation is much better than the 1 other calyx that I have ever found there which I gave to DevonianDigger earlier this year. Here are a series of pictures that try to give the different views. There is the remains of one arm but it is disarticulated from the actual calyx.
  7. Help with Mississippian crinoid calyx

    I took my 4 year old Son geode and fossil hunting near the Missouri, Iowa, Illinois borders last weekend. We had a blast and found a lot of cool stuff. I found this calyx in the Warsaw formation which is Mississippian. It's obviously not done being prepped, but i figured there might be enough showing to get your opinions. It's actually been quite a challenging prep and may take some time to finish. I was thinking a possible Agaricocrinus sp., but it doesn't quite fit the bill. I can't find anything that looks identical. Any help is appreciated. @crinus @Crinoid Queen you guys still around? As found Some prep
  8. I got my hand on a Crinoid calyx from somewhere in Texas (no location attached other than creek), and I’d like to know if this should be prepped any more, and if it is worth seeking professional help (I certainly can’t do it yet). It’s around four inches (I think, it’s not with me right now). Thanks for any advice!
  9. Two calyces from Michigan

    Last weekend, I spent a day at one of my favorite hunting grounds in Alpena, Michigan, on Lake Huron: Partridge Point. (Thunder Bay Formation, Devonian.) There's a lot of fossiliferous matrices in limestone. You also find lots of crinoid columnals. Last year, at this location, I found my first -- and only -- blastoid (Placoblastus obovatus). This time, I walked away with two calyces: I believe the first one pictured here (two images) is Megistrocrinus depressus; the second looks like Dolatocrinus asterias. Have I identified these correctly?
  10. Crinoind Calyx Extraction

    I have found a large rock containing a crinoid calyx. I am deciding whether or not to extract the fossil from the rock it is in and if I do extract it, how should I go about doing that? If you have any additional information you can tell me about this fossil please do so!

  12. Calyx - Interestingly intricate features

    Hi again fellow chippers. I broke one of my cardinal rules and did not wash / scrub the chunks before busting them up. This shale is very near the surface so it is covered with a layer of silty mud, dirt and small roots which hides some of the fossils that are on the surface of the natural fissures. I did not notice these calyx's until after I had busted the chunks up looking for my ever elusive complete trilobite. The one has a very interesting pattern within each polygon that I have never seen here before. The other is very similar to the others I've found here. Amazing, the geometry of nature .... just amazing. Thanks
  13. Crinoid ? good condition ?

    Hey friends I took a little walk at lunchtime today cracking shale along the way. Found this in the split of a piece of the harder gray/black/blue shale that doesn't have many fossils in it .... that I have found, anyway. Is it a crinoid ? from the calyx up ? Very interesting tentacles ... or whatever they're called. Its quite small. The calyx (if that's what it is) is about 5mm diameter. Could this be prepped out ? Looks like it would all be there, but quite delicate and tricky to expose. Thanks for looking
  14. Crinoid ? or Coral ?

    Hello friends, I found another calyx ....or coral. This one was deep in a split and was not exposed like the others. I lightly brushed the residue away. I left it like this for the pic to maybe aid with ID. I think it would look much like the others if it were cleaned up. If any other views, or exposure would help, just let me know. Its 1.5 inches diameter. Thanks !
  15. Another crinoid calyx

    Good day folks, I found another crinoid calyx similar to the ones found earlier but with a little bit more definition. I exposed this one with a split, the others were on the exposed surface of a piece of shale that was loose in the plowed up rubble. I was hoping to find more of these, this one was just a few feet from where I found the other two. The gastropod was a bonus. And of course, two more trilobite pygidia along with this small cephalon ... # 29.
  16. Calyx, exposed

    Hi folks, I posted this calyx for ID some time ago: http://www.thefossilforum.com/index.php?/topic/75522-not-a-clue-here-please-take-a-look/&page=2 Since then, I decided to do a little prep on it to maybe expose more of it. Sadly, I did not get very far before it "grew" into the matrix ..... dang it ! But it does look a bit better, amazing to me. Thanks again to all.
  17. Blastoid and crinoid mix up

    I while back I acquired a collection of fossils,minerals, and rocks. They were apparently found at an estate sale before being bought and sold online, hence the prices on the labels (not what I paid for them). It was rather large and confusing, but I managed to figure a lot of it out. One bag, however, has crinoid and blastoid stems and calyxs (calyxi? Calyxese?) and six labels, none attached to the specimens. I was wonder if y'all could help me sort them out, because I'm confused. A few of the labels are just "crinoid stems", is it possible to get a better ID on them? I can take more pictures if needed.

    From the album Some Highlights from the PD weekend

    Just seeking confirmation that this is indeed a crinoid calyx. This was found in the lower Windom, and from what I hear they are not terribly common.
  19. Smashed crinoid calyx?

    Hi esteemed forum members, I have several finds I need help identifying, but I'm going to do them in separate posts/threads/topics/whatever. I found this one in some Burlington Limestone in central Missouri. It's super brittle. You can see areas where pieces have just flaked off. The lines you see going across the front of it are raised. The leading theory on this so far is that it's a Rhodocrinites calyx that flattened during diagenesis. I've also attached an image of the small matrix it came off of (I found the calyx, if that's what it is, in situ unattached, just laying there on top of the matrix). Let me know. And stay tuned for other, and probably less exciting, ID requests. Thanks!

  22. Crinoid Calyx bottom

    From the album My very first identified fossils at the fossil forums

    Calyx is a term used to identify animal anatomy for some cup-like parts, or areas This Calyx is from a Crinoid, a marine animal from the class Crinoidea of the Echinoderms (phylum- Echinodermata - ancient Greek - This is the phylum that brings starfish, sand dollar and sea urchins in which the adults are recognizable by their 5 symmetrical sections (5 star points) This Crinoid Calyx measures 1" x 1" x 1"

  24. I frequently come across a nice specimen that has no label. It becomes an unknown and has minimal value because, the geologist, in this case did not insert a label into the container as to location and formation (Period, Formation, etc.) I scanned both sides. It measures 3 inches by 1 1/2 inches. This is an interesting specimen as it is loose of matrix, obviously weathered out in this condition and is a flattened nearly complete calyx with arms Wouldn't we all like to know where this one came from! My offer is this. The first Forum member who can identify this as to just... Genus... will be the owner. I will pay the shipping within the USA. If you are in Canada or outside of North America you could Pay Pal me the shipping costs, which would be fairly low. Rules: If you come up with an initial identification you must provide the REASONS and a scan of the Crinoid used to identify this specimen. If there is a dispute among several members as to the identification, other Forum members can jump in and support the closest correct identification. If there seems to be conclusive agreement... then I will check my Treatise of Invertebrate Paleontology- Echinodermata... locate those identifications and make a knee jerk selection of a winner, if necessary. First most accurate identification takes the prize. I have no clue nor have I tried to find an identification. I would have to believe it is Silurian, Ordovician or Devonian. It is not a Cretaceous floater from the Kansas chalk.
  25. Mississippian Crinoid Calyx

    I found a real treat, I think. I believe this is a crinoid calyx. It's very light weight, hollow, with maybe a few calcium crystals within. Would u call this matrix mineralized?
