Hello! Looking to see if anyone can tell me what species these crinoids are! It was found in O’Fallon, Missouri. Mississippian Period limestone rock outcropping (road cut). Specific location: (38.8189493, -90.7276743) These are the same fossil ^^^^ These three are the same^^^

Show us your Devonian Epizoans & Pathological Brachiopods!
Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 225 replies

We've been finding these oddball puffy stars in the Late Ordovician (Sandbian) of eastern Missouri (Illinois Basin), in the uppermost part of the Plattin Group (a Platteville equivalent) or possibly the lowermost part of the Decorah Group (Katian). We've been finding a lot of weird fossils in that zone, including articulated cyclocystoids, but these I'm at a loss on. They seem to be calcite and preserve in the same texture and color as other echinoderm material in the same rock. They vary in convexity and in the presence of a central hump or divot, but there never seems to be a lumen that goes

A friend uncovered this oddball today in the Late Ordovician (Sandbian) of eastern Missouri, in the uppermost part of the Plattin Group (a Platteville equivalent) or possibly the lowermost part of the Decorah Group. He's been finding a lot of weird fossils in that zone, including articulated cyclocystoids, but this one I'm at a loss on. Too wobbly for an orthoconic cephalopod, too much space between calcite elements for a crinoid column. Given the size, is machaeridian a possibility? What other ideas should we be considering?

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com- 5 replies

Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can'

Ordovician or Silurian erratic boulder from Poland. Sorry for poor quality photos - I'm not able to get better for now. What are these 8-shaped lumen ossicles? Also, can you spot fragments of calyx?

Ordovician or Silurian erratic boulder from Poland. Sorry for poor quality photos - I'm not able to get better for now. Is this a chance association or can you spot fragments of calyx, stem, and cross sections through arms? What crinoids are these - crotalocrinitids?

Erratic boulder from Poland. Age unknown but likely Late Cretaceous to Danian. The silicified concretion is developed around a sponge, visible in view places, like the spot on the photo. This specific spot bears also a ramose feature. Could it be part of the sponge anatomy or a crinoid root?

Southern Poland. Found in parking lot gravel, so age unknown, although Late Jurassic or Late Cretaceous to Paleocene likely. I quess it's an isocrinid - could anything more be added to that?

К сожалению , я не говорю по английски, но я не плохая фотография, так что позвольте мне сказать , мои фото .. На фото полного цикла от процесса экстракции до готового образца морских лилий Neotaxocrinus. Искренне, Александр Unfortunately, I do not speak English, but I'm not a bad photograph, so let me say my photos .. On the photo of the complete cycle from the extraction process to the finished sample of Neotaxocrinus sea lilies. Sincerely, Alexander

Good afternoon, My name is Rick, and last summer I purchased a big box of fossils. I got the box mainly for the ammonites that where in there. The box containted about 50 fossils. I was wondering if you could help me with the names of the following fossils. I know some of them are crinoidea and brachiopoda, but I don't know which crinoidea or brachiopoda they are. I hope you can help me out! This a the link for an online album, containing every unknown fossil (11) Album Kind regards, Rick
