Here’s a small hash plate from the Carboniferous of Lancashire in the U.K. I found it a couple of years ago but I have only just got around to cutting it down to a displayable size. It was part of a much larger block and now it’s about 4 inches by 4 inches. It contains a crinoid calyx, some crinoid ossicles and stem pieces and bits of coral. It is from a place called Salthill Quarry

Hey everyone, hope you’re all doing well. I was on a walk the other day in a local nature preserve with my son when I stumbled across some fossiliferous stones in a pile. These contained mostly brachiopods, but one in particular had crinoids stems and another structure I wasn’t certain on. I’m not familiar with this place, looking up the area puts it somewhere in the Ordovician (either the conococheague, Stonehenge or stoufferstown formations) but these stones had been deliberately placed in a pile so I can’t say for certain if they came from the location or were brought in. So I have 2 q

Don't ask me how I find the tiniest things in existence, it's a gift, lol. I don't have a proper scale on hand, but the stone is about 7mm, corner to corner at the longest. I was thinking maybe a partial crinoid or some sort of arthropod, but the underside is dimpled sort of like volcanic rock, so maybe it's just a feature of the rock and nothing more? I'll try to add more details when I get home. Found in Doña Ana county, New Mexico.

Fossil preparation / enhancement with the help of heat
FranzBernhard posted a topic in Fossil Preparation
I would like to ask if anyone has experience with fossil preparation with the help of heat. My question is triggered by that topic: Authenticating quartz (?) Keichousaurus? - Is It Real? How to Recognize Fossil Fabrications - The Fossil Forum My hypothesis is, that this specimen was baked (as a whole or only superficially, with a blow torch, for example, possibly several times) to promote flaking off of the matrix. Could this be correct? Another question: Some time ago, a baked crinoidal limestone was shown here on TFF (with color turned from a somewhat uniform gray- 7 replies

I picked up a stone which had a nice crinoid segment imprint on it. Under closer investigation, I found other microorganisms as well. Any idea what they could be? Crinoid is 2mm and the microorganisms are 1mm at the largest. Found in Doña Ana county, New Mexico.

This came from the Brad Formation, Palo Pinto County of Texas. It's in the Missouri Series of the Late Pennsylvanian. There seems to be crinulations like you see on crinoid stems but there are nubs poking out in a completely random way in every direction. Some of the surface looks a little like calyx plates but there is no obvious symmetry. It could be part of a holdfast since I am not familiar with them but I have no idea for certain. The scale in millimeters.

Hello, I have two slabs that I would like ID help with, one is a hash plate with trilobite cephalons and pygidiums, the other has a crinoid calyx/crown. I'm told they were collected in Reynolds County of Illinois, USA. I did some googling and I don't think there is a Reynolds county in Illinois, but there is a Reynolds village in Rock Island/Mercer County Illinois which is what I'm guessing the seller meant. Anyways, assuming this info, the geological map of Illinois suggests that this locality consists of the Tradewater Formation which is Pennsylvanian in age:

Here is a rock I found over the summer but I am continuing to clean. With the tools I have and the rock's size it is quite difficult to get dirt out of the small bits but it's looking much better. I found this very early in my fossil collecting hobby so at the time I didn't know much about what it was, but I now know that it's crinoid bits (perfectly obvious to me now of course, but it's part of the experience). One thing that's cool is when I first uncovered it, it looked like the whole one side had the bits, but you can see along the middle there isn't as much debris as the sides, which lead

Hello, Does anyone know who would be the go-to authority on Pennsylvanian crinoids of North America? The most prominent paleontologist I can find based on publications is Harrell Strimple, but he's unfortunately passed away many years ago. I have some specific questions I'd like to ask. Thanks.

These crinoid segments look amazing in their natural color -
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^^^

I found this in a creek bed in Arkansas. It looks like it could be a crinoid stem. The size is about 1.5 by 2 inches

Is this a crinoid, coral or a shell? (Wales)

Back in June, I posted this Burlington crinoid, wondering if it was worth prepping out. Responses were fairly cool except to say it may be worth a bit of exploration to see. @Ptychodus04 volunteered to give me a hand. He was instructed to put about an hour of work into it and then return the crinoid to me. His resulting exposure left me with the nagging question of do I go further. It was not worth professional prepping, so all summer and fall it sat on my desk begging to receive some attention. This week, I grabbed the specimen and kept whittling away at the matrix u

The fossil was found near Babler State Park in Wildwood, Missouri, Fern Glen Formation. My best guess is a crinoid holdfast. I've found small crinoid stems and brachiopod fossils in this same creek.

Earlier this month I spent a day collecting in the Kope Formation (Upper Ordovician) of northern Kentucky. It is one of my favorite formations to hunt, and I always walk away with some nice stuff. Here are some of my better finds. A decent Ectenocrinus. It is crushed but should turn out nicely after prep. A much smaller Ectenocrinus hiding in a hash plate A pretty classic Kope hash plate. There's a cluster of crinoid arms to the left of center - I doubt there is a calyx but we'll see. A very nice Cyclonema

Happy new year! I wanted to show some of the highlights of an unexpected discovery from December 31 last year. I was in my garage when I noticed a pail full of rocks so I decided to try my luck and see what I could find. While I expected to find a crinoid stem at best, about 75% of the rocks ended up having something or another in it! 38 rocks in all ended up being relocated to my room, some have just a few brachiopods or whatever, but some I only have the slightest idea what they are, so any suggestions are much appreciated. Unfortunately I have no idea where any of these came from so there's

Trying to determine if this is a Crinoid or some sort of coral. From the Mahantango formation (Devonian) of Pennsylvania

Been finding some fossils not related to the Moenkopi or Chinle recently. I assume they washed into the area. Haven’t gotten positive identification of them.

This was found in a dry portion of creekbed where Devonian age bedrock is out cropped (Lime Creek formation, Mason City, IA). The fossiliferous layers contain bryozoans, stromatoporids, brachiopods, crinoids. After using a tooth brush to rid it of the loosest matrix, this is how it looks. I've attached some microscope pics of the specimen as well. It's essentially a specialized webcam connected via USB to a computer. I'm not able to definitively discern what this is. I'm hoping it's a crinoid calyx but the closest resemblance seems to be some species of oyster. Any suggestions

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg

Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you w

Few weeks ago started breaking open some pieces of shale. I've found lots of trilobite fragments that I'll post later, but what's intriguing me is these small bits of things that I find quite a lot. I can't find anything on what they might be and my closest guess is perhaps some bits of crinoids? Does anyone have more experience than me with such things?

Searching for origin of this hand drawn Crinoid image
mem posted a topic in General Fossil Discussion
Greetings I am working on a paper regarding the subtle forms found in crinoids. If you have seen this in a publication. Could you point me in the right direction? Much appreciated.
