Found this echinoderm in Paleozoic rock. Crinoid calyx or something else?
SilurianSalamander posted a topic in Fossil IDFound in some landscaping gravel I’ve found boatloads of crinoid stems at. Brachiopods and gastropods are not too uncommon in those rocks. Paleozoic, likely Ordovician-Silurian.
ID help please. Weird fossil?
Scottnokes2015 replied to Scottnokes2015's topic in Fossil IDHi everyonei have reposted my id request as I'm having trouble with my other post. This is the fossil in question. It is from Chester, Illinois which is Mississippian formation and it's a limestone. In that area, fossils tend to be very heavily calcite. I found this we're the questionable part was circular but broke while removing and leaning what I have. I have had various ideas from local enthusiasts that it is a crinoid basal plate. Can anyone give me a more detailed ID or possibilty. Thank you

Crinoid calyx cleaning
Jackson g posted a topic in Fossil PreparationWell I have been off of work this past week, and I start back this following Monday. With some of my extra time I've had, I've started work on prepping/ repairing some of my bulk Burlington crinoids that have just been sitting around. All of these calyxs are in different stages of completion, due to me always hoping from one to the other. Starting with one of my favorite species, Azygocrinus rotundus. This piece is mostly completed, I just need to finish working the matrix to however I'd like it. Next we have a mostly complete Uperocrinus pyriformis. When working
Burlington crinoid calyx ID second opinion: Agaricocrinus planoconvexus?
Jackson g posted a topic in Fossil IDFor those of you familiar with crinoids of the Burlington Formation, (Mississippian) I would like to get a second opinion. This calyx is partial, but I believe there is enough present to confirm my guess for ID as Agaricocrinus planoconvexus? I haven't collected even a partial of this species yet, so confirmation would be exciting. Thanks for your thoughts, Jackson Top Bottom Side shots This other one is probably complete. If it takes me prepping this one to get a 100% confirmation, please let me know and I will do so. (Would rather kee
Azygocrinus rotundus crinoid
Jackson g posted a topic in Fossil PreparationWhile I was out today I found a nice crinoid in a big chunk of crinoidal limestone. I decided to take one risky wack to the opposing side of the calyx with my Estwing at the rock, which ended up working out well. Most of the time I wouldn't bother because it never goes this smoothly, but I have a lot of this species so I didn't mind if I busted it. The circular calyx is very reminiscent of Azygocrinus. After splitting the rock, I took the half home with the crinoid. The rest of the work was done with airscribe. I'd say it came out pretty well. Once I had the size of the
Pippa posted a topic in Fossil IDI would love your opinions on these Lake Michigan, IL beach finds. Am I correct in thinking that these are crinoid calyces? As always, thanks so much for your input. A Hash rock with a terribly worn crinoid but with the outline of its calyx visible? The cup shaped (bottom part only?) of a crinoid calyx? Upside down view. Ca. 1cm wide View of the bottom Top view: Plate from the IL Geological Survey: Or something like this silurian crinoid "Sagneocrinites Expansus":
Road Cut Hunting on 11-4-2019
rawwardigger posted a topic in Fossil Hunting TripsI stopped at several road cuts on both sides of the TN River in Decatur and Wayne Counties Monday (Nov. 4, 2019). Two more damaged Rhizophyllums without the lids, some really nice geodized Crinoid and Cystoid Calyx along with several geodized stem segments and a geodized horn coral. Cephalopod sections in situ, other Calyx pieces, etc. I'll try to get better pictures soon!! Thanks For Looking and Keep On Rocking, Roger

From the album: MY FOSSIL Collection - Dpaul7Eupachycrinus Crinoid Calyx Chesterian Zone of the Bangor Limestone Formation in northern Alabama TIME PERIOD: Mississippian Period (ca 325,000,000 years old) Data: 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 com
Please ID possible crinoid calyx impression
jewelonly posted a topic in Fossil IDA friend of mine found these fossil impressions while digging the foundation of his house near Huntsville, AL. This is Mississippian, Bangor Limestone Formation. In trying to identify the species, he thought it might be megistocrinus sp. He would like a definitive ID, if possible, so I appreciate all help. Thank you, Leah
Hungry Hollow Oct 24, 2013 Crinoid Calyx And Other Fun Stuff
lmacfadden posted a topic in Fossil Hunting TripsMade it to the South Pit of Hungry Hollow today for 3 hours and found a few interesting bits. The most interesting was the crinoid calyx. It's amazing what a little rain will uncover.
I Thought "crinoid Calyx" When I Found It But Maybe It's Coral?
lmacfadden posted a topic in Fossil IDNeed help - what is this? I mostly find horn coral and button corals at the south pit in Hungry Hollow, Ontario but this one is unique. Can someone tell me what it is? It is 7/8" long...
Mississippian Crinoid Calyx
KyWahine posted a topic in Fossil IDI 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?
