  1. Crinoid and Petalodus Tooth Help

    I am looking for some help on a couple small pieces that I just happened to buy today when I stopped in a small store. I normally would not buy things without proper id’s, but the prices were right. Scale is in inches- The first piece has what I believe are two different Crinoid calyx- the tag stated that it came from Grantsburg, Indiana and it also had “Haney Fm.” Written on the tag. This was on the back of the plate.
  2. Fossil (maybe) in chert

    Okay, this is way, way out there, but it's a maybe. I am sitting on the fence for going real or mother nature. I was strolling around the mountains today. On an Silurian plateau I spied this piece of cherty material with what may or may not be a small crinoid. It is a bit banged up, kind of rusty looking, but seems like an immature crinoid??? Otherwise, a very interesting want-to-be. Material is missing from some areas which would have been helpful and it wraps around the edge of the rock making it challenging to photograph. On the entire chunk of rock there are no other features of note. Size from 8 on the ruler as it wraps around the other side comes out to about 35mm
  3. I recently acquired a Daedalocrinus bellevillensis crinoid fossil plate from the Bobcaygeon formation of Brechin, Ontario. At the bottom of the plate is what appears to be an annelid worm fossil. It is segmented but the segmentation is nothing like the segmentation of any crinoid stems I have seen and is more similar in appearance to a modern earthworm; it also terminates with a point. It also has occurred to me that this might be a frond from a crinoid but I don't know what the terminations look like. Would anyone have any suggestions as to how I might identify this fossil? The picture doesn't do justice to it but the item of interest is the item crossing the crinoid stem. Any suggestions would be appreciated.
  4. It just looked different. I think its a fossil of some kind, is it another Crinoid?
  5. Clarksville Indiana Crinoid Like Fossil

    I was collecting fossils in Clarksville, Indiana today at a site I typically find a large amount of Devonian fossils. Some recent rain had washed out a number of small fossils to easily collect. I collected this fossil without thinking twice, but since cleaning it up I realized it doesn't match any in my identification guide. I originally thought it was part of a crinoid stem, but I can't find any documentation to support that. I've spent the last several hours researching and cannot find a match for it. Now I'm at a bit of a loss and would love some input. Thank you!
  6. I have jokingly told people there are literally trillions of crinoid column fragments in this area but I have only found bits and pieces of the crowns. On Christmas Day, while hiking with my wife, I found what I think may be a potential crown in a rock having lots of column fragments. Thus, my request for some substantiation of the possibility. If this is a crown, I will go back to try and field extract just the portion of this rock having the specimen. I think it would be a good one as a 1st experience for exposing/prepping to reveal more of the fossil. The width of the specimen is just at 2"
  7. Coffee and Crinoids

    While visiting family and high school buddies over Christmas time, I was able to schedule a long awaited meet and greet with Tri State native Dom (Fossil Claw) and made a hop over to Indiana for some Mississippian action at dawn. Fortunately the first morning rays revealed undisturbed, fertile ground free from the scratchings of eager collectors. The ground was frozen and frosted over in the 27F air, so we donned gloves and knee pads for a low and slow peek into the long shadows. A couple Pentremites blastoids surrendered their crowns right away. When Dom asked if I was moving along too fast, “Holy smokes!”, or thereabout, was my response as I pointed in disbelief at a nice crinoid crown poking out of the clay at me. The crown looked fragile, and after a short conference, Dom offered up the best idea to free it from the frozen clay: hot coffee from his thermos. The stream of joe melted the mud away like butter, and I carefully wrapped it up in my knit hat for safe handling and travel. A steady stream of blastoids punctuated the hour of so we spent canvassing the outcrop. Then I dropped to a lower level bench for a fresh crawl. I was shocked to lay hands quickly on a second crinoid crown, then a limestone slab with 2 shark teeth, or fragments thereof, poking through. With a continued parade of blastoids, including some multislabs, we decided to leave some for the next guy and headed home to check out Dom’s collection. This was a great first get together with a fellow collector.
  8. This is not a perfect tooth but it’s all natural and massive. It has a gorgeous mottled blue and yellow color. I’m mostly interested in: crinoid specimens, shark and mammal teeth, and non-Utah trilobites. I’m also happy to look at other offers that don’t fit the above list.
  9. Crinoid stem but is there a Calyx?

    I have looked at this piece for about 1 week and my opinion changes from a crinoid stem and calyx to a crinoid stem and broken gastropod and back. So I will now defer to anyone visiting this post to leave their opinion seeing I can't make up my mind. I have both specimens marked.
  10. Crinoid matrix preparation

    Hi, Can you please help me with what I can do to restore/prepare parts of crinoid matrix that has eroded. This piece has been in the storage for several years wrapped up, and after taking it out for display, I have noticed small sections of the matrix started to come off in fine dust. What kind preparation is needed to seal/restore the light coloured exposed matrix surface to its original darker colour? Thanks in advance.
  11. Trilobite and Crinoid ID

    All right TFF family, my friend who owns a local rock shop is in need of IDs for some trilobites and a crinoid. I think these are probably from Morocco as most of the collection these came from are Moroccan and the trilobite prep looks typical of the area.
  12. Crinoids in epoxy

    This is more a piece of artwork than a prep job. In my area they excavate Belgian blue hardstone and is used a lot in buildings. This is a durable crinoidic limestone from the early carboniferous ( Tournaisian ). I've colected multiple times in one of those quarries, and in some layers you can find countles crinoid stems. Now I had the idea to use a discarded piece of this crinoidic limestone and make a hole in the middle , I filled up the hole with transparant epoxy in multimple layers and between each layer I droped a few of the crinoid stem's that can be found in the stone. I pollished both sides of the piece so that you could see through the stone and the fossils in the epoxy to create the idea that you can see through the stone and see the fossils in the limestone.
  13. Hi guys! This is a continuation of a previous post focusing just on the sponges. These fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. Because these fossils are in the park, no collecting was allowed, and I can't provide additional images. Any confirmations about the identification or suggestions about a more specific identification are welcome. This trilobite is the only fossil out of these images that was actually found in Carlsbad Caverns, right behind the elevator. Can I get more specific on an ID? Cross section of rugose coral? Sponge? Bryozoan. Acanthocladia? Bryozoan? Crinoid.
  14. Crinoid stem segments from arkona Ontario.
  15. Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella?
  16. Platteville Wisconsin Crinoid Help

    I think that I found a small crinoid in the Ordovician aged Platteville Formation of Southwestern Wisconsin. i know there is not much to go on but am hoping someone can confirm that it is a crinoid. Any idea on species would also be appreciated. The specimen measures around an inch.
  17. echinoderm or what?

    this is 1/2" across, the opening is 3/8" sandstone matrix, calcite thingamacallit found in Meade Co, KY about 300 feet above the Ohio River. Thanks for help
  18. 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.
  19. Just reassembled, crinoid stem with a bit of character. Probably Poteriocrinus sp., or maybe Rhabdocrinus, 20cm long, 10-12mm diameter, in a high energy deposit full of crinoid, bryozoan and brachiopod débris. It's unusually well articulated for this bed which mostly contains smaller broken bits of stems, arms and plates. There's a probably pathological swelling towards the top, above the radices. Last photo shows it as collected - very fragile and the main stem had largely broken into calcite cleavage fragments. Prepping so far was just a matter of letting it dry, then gluing, poking off shale with a needle and scrubbing (wet again) with a toothbrush. I'm letting it dry thoroughly and will then consolidate the sides and base of the block with thin paraloid solution. I might then air abrade a bit. Brigantian, Co. Durham, UK.
  20. I went on my first real dig yesterday at the Ernst Quarries of Bakersfield. I won't say it was easy, but it was pretty rewarding. Aside from a bunch of very small shark's teeth, I found a fossilized piece of a stingray barb grinding-plate, and this particular piece. At first I thought it was a tooth from some ancient fish that had teeth that looked like tusks. After looking at it for a second more, I realized that it was something else. Crinoid came to mind. Being a newbie, I just wanted to get verification of this pieces "crinoidness", or lack thereof. Is it a crinoid fossil, and is it common in places like Bakersfield oil country? Many thanks, learned fossil-folks, et. al. Cheers.
  21. CP crinoid stem in north China

    It is in Yangquan, Shanxi province, which is a known for its CP coal mine ( the best in China) and fossils. This is the well known Taiyuan Formation (late philadelphian, late C early P) . Tons of marine stuff, you have to literally walk on the crinoids and brachiopods calcite, yet a few dozen meters away you see the land plant fossils like cordaits. I saw crinoid stem pieces in all shaps, round rings, roud rings with radiant rays, eclips rings, penta rings, and square and rectangle pieces ( one in the foto), as well as internal molds. They are every where scattered. I have little knowledge about it. I wonder if I could get any help here, like possible ID, or if there is any on-line place to learn. I only have some generic paleotology book and a small chapter on crinoids fossils, and only a few sketchy words for crinoid stem in CP period.
  22. Crinoid Prep

    My other current prep is a nice crinoid slab. Here’s what it looked like in the beginning. Large, thin, and VERY cracked.
  23. While I find interest in every fossil my daughter and I find, I’m feeling a bit frustrated at finding only Crinoids. Yes, I think they’re cool, and I don’t want to be ungrateful, but I’m getting a bit discouraged.. I’d like to find something other than a Crinoid. Now, admittedly, I only know certain places to look, so that’s why I’m reaching out for help. We’ve primarily looked in creek beds, and along the trails we walk. I’m in Boone County, MO. Can anyone give us any tips on other places to look where we might find something other than a Crinoid? We’re new to fossil hunting, so honestly any tips you have will be well received and we’d be so grateful for them. Thank you in advance. (photos for attention.)
  24. Your Favorite Find?

    Hey, I hope this is the right forum! I’m new to TFF, so idk if this is allowed or not, but figured I’d give it a shot. Admin, if not allowed, please delete and let me know. Thanks!! I’m curious to see your favorite piece in your collection. Post a picture of your favorite find, and tell me a little bit about it. What time period is it from? Where did you find it? (I.E., US, England, etc.) Is it rare? Why is it your favorite find? I’ve got a couple of favorites, but I’ll just post one. This rock in particular is teeming with history! On this one rock alone there are fossils of Crinoids, some with, what I believe to be, pinnules still attached. It’s got fossilized shells, imprints of shells, Crinoid stems, etc. Its my favorite because it’s just got so much history packed in to it! It was found in Boone County, MO., USA. I believe it to be from the Mississippian Era. These are all found on the same rock. (I’ll add some more pictures to the comments.) If I’m wrong in my guess on what they are, please correct me! I look forward to seeing your favorite find!
  25. Can anyone confirm this for me? I believe it to be a top view of part of a Crinoid. It was found in a creek bed in Boone County, MO. I believe it to be from the Mississippian Era. It looks to me to be two of the arms laying down, as if you were looking at the Crinoid from the top. Am I accurate in this? It is super small, at maybe 1/4 of an inch big at the opening, though it goes maybe an inch deep. These are the clearest photos I could get of it, as it’s dark in there, and it’s so small. The opening measures 1/8th of an inch tall. It is 1/4th of an inch wide, and from the top of the opening to the bottom, crystallized circle part, it measures 1/2 an inch.
