  1. Hello, I'm considering this crinoid, listed as Eucalyptocrinus crassus. It is about 6cm. I was wondering if there looks to be any reconstruction/repair, and if the preservation quality looks to be good/bad/typical of these specimens? I'm not an expert on these but from what I understand this specimen has the arms attached and preserved on the crown, but it is a little crushed? I'd like to add it to my collection if it's in decent state. Thanks.

    Crinoid Segments

    From the album: Delaware Fossils

    Oddly smooth, but typical of this locality, these crinoid segments are only about 2mm in diameter. From the Cretaceous spoils deposits of teh Chesapeake and Delaware Canal, Delaware.

    DSR Crinoid

    The other day I was splitting some shale I brought back from a trip to DSR and found this awesome crinoid! It's the first complete (arms+ calyx + stem) I've seen from DSR. I'm going to have the stem transferred and then have it air abraded by a friend of mine, hopefully it'll be easier to ID by then. For now, my best guess is probably Gilbertsocrinus spinigerus

    Possibly a crinoid?

    Found in a creek in Pekin, Illinois. It's a concretion with a nice fossil imprint. However, I do not know enough about it to classify it. Does anyone have any suggestions?
  5. Tetradium

    Glyptocrinus sp. ?

    Ordovician, Decorah Formation Minnesota Just want your opinions on it before I post it to my image gallery. I'm not a crinoid expert and this is rare - only my second crinoid from the Decorah Formation with more than 60% completeness. The first is a tiny one not even 2 inches from crown to base. This is more of a medium size with 110 mm from head to base. Using paint I pinpointed different areas for helpful info. #1 Is the arms - can't really see in picture but very clear to me some scavenger buried the arms - I could see a few faint tunnels a short distance away.

    Trip to the Texas Permian

    I have been incredibly bad about writing this trip report, so I am glad that I have finally gotten a rainy day to put it together. Back in September, I joined the Paleontological Society of Austin on a field trip to two sites in the "Heart of Texas," one in the Pennsylvanian and one in the Permian. I had never before had the chance to collect in the Permian so I was really excited to go on this trip. @erose did a great job explaining the stratigraphy of the sites and what we should look for. Erich explained that the Permian site was an exposure of the very early Permian Moran Formation. The hi

    November Trip to Wilson Clay Pit

    @JamieLynn's post about the recent PSoA field trip to Wilson Clay Pit reminded me that I was in need of creating my own trip report too. Early last month I made my first ever trip to Wilson Clay Pit in hopes of finding some of the incredible Late Pennsylvanian echinoderm and vertebrate material that I had read so much about. I was a little nervous about visiting (after hearing stories about rattlesnake encounters), so I was fortunate to convince a friend to join me. He must have brought the luck because not only did I find two nearly complete Petalodus teeth and a nearly complete Petalodus cro

    Are these crinoids?

    These three fossils in the upper left of the picture were found in central Pennsylvania. I am relatively new to the world of fossils so I'm hoping someone can help identify what I have found. Are these crinoids? Thanks in advance!
  9. Last month I took a weekend collecting trip down to the Cincinnati area as my last trip of the year. I visited a number of sites in Indiana and Kentucky, and as usual this included the famous Upper Ordovician roadcut near St. Leon, Indiana. Although this site is best known for its trilobites, I found a great crinoid on my last trip there, and had some further crinoid luck on this trip as well. I spent most of my time in and around the butter shale bed of the Liberty Formation, shown below. The find of the day came when I noticed a large accumulation of crinoid stem fra

    From the album: C&D Canal Micro Fossils

  13. Just saw this new book published by the IU Press. I think there are some members here who might find this interesting. https://iupress.org/9780253058232/collectors-guide-to-fort-payne-crinoids-and-blastoids/

    Ordovician donut from Maysville

    I found this strange specimen in the Upper Ordovician Fairview Formation outside of Maysville, KY. The thing attached to the donut looks like it could be a crinoid holdfast, but if so I can't recall having seen a similar one from the Cincinnatian. But what might the donut be? A large trace fossil? A strange sedimentary structure? I really have no idea, I've never seen anything similar before.

    Micro-vert or crinoid ossicle: Jurassic finds

    I keep finding these peculiar ovaloid shaped fossils in the Cotswolds, Inferior Oolite Group, UK. It doesn't particularly matter which formation they are from, as I've found them in every single one so far! Here's one of them. They always have a side with a convex bump on it (pictured above), and a side with a concave dip, suggesting tessellation. And here's some microscope images:
  16. I know not much about Crinoids but have taken a liking to one and due to my previous purchase I wondered if anyone can please confirm if this is real or not? thank you

    Weird black thing

    I saw this little black thing on a crinoid plate, and I haven't been able to figure it out. It looks almost like a trilobite cheek or a cephalon or maybe even a crinoid calyx shard. Anyone know what it is?
  18. Hi all, me again. Went on an expedition with my dad to show him what I do on my free time . Did some research into nearby formations and saw a promising one was in Gore VA. After casing the place in google maps dad and I arrived there at highway 50 we started on the road cut across from the meeting place. The formation seemed promising from the road, but after finding only the same old brachiopod molds and crinoid stems I saw it as a bust. Not deterred, I set on doing a little more follow up research and found that the Legendary store was nearby. After relocating we st

    Possible Crinoids

    I don’t know where this is from. Is it a Crinoid?
  20. The new collector

    Can you help me identify the fossil species

    Hello I’m new to the hobby , what species are the fossils i didn’t find them , I bought them from a box thanks for reading
  21. Just wanted to show the tiny segment I found tonight. Plattin formation. Almost as small as my tiniest segment different species though.
  22. Hi everyone this is Matt again. Take a look at this crinoid stem fossil I found in the creek today. Here is a photo :
  23. Hi all, I went on my first fossil hunt today! Destination was the DSR quarry near Hamilton, NY. We had great fall weather and the leaves are really starting to turn. Here’s who we encountered:
  24. Sorry I don't have better info or more pics, but my friend found this on the Blackfoot rez in Montana this summer. He said it was "about the size of him", he's around 5' 10". I'm thinking coral or crinoids, but I'm not very knowledgeable about inverts. Any insight is appreciated!
