Hi everyone, thanks for checking out my post! I found this dude at the beach a few days ago and haven't quite pinned down what it is. It's formed like a bowl, with three lobes and has what appears to be a crinoid in the center on one side. I've found some similar objects under the crinoids and blastoids tab, but they're not quite right. If it is a crinoid, I would very much like to know what part of the animal it represents, a part of the holdfast maybe, or of the calyx? Found on the beach in SW West Michigan, Berrien County. aprox. 9mm on one of its three sides, and 4mm high.

Can you ID where a square crinoid columnal fits in it's morphology
Denis Arcand posted a topic in Fossil ID
The crinoid columnals i have found are usually round, pentagonal and star shaped, but today I found one that is square Among a thousand crinoids columnals, this is the only square one I have ever found, why? To which part of the crinoid does it belong to? -
Howdy folks. Been a while since I’ve posted. I went through some significant personal losses and haven’t been on TFF in much longer than I’d have liked. After over a year, I’ve finally gotten out to hunt, this time in an area I’d never been to. (Also, if you’re in the Jacksboro area, my water bottle unfortunately fell out of my backpack, and I would really like to get it back since it’s been on a lot of trips with me. I’d pay someone to go get it if they’re nearby!) The weather was pretty nasty, raining and thundering a good amount of the time I was out hunting.

From the album: Finds from Solnhofen Jurassic Limestone
Crinoid from the Altmühltal Formation, Upper Solnhofen Subformation. -
I was going through some material I collected circa 2001 and found a crinoid that is not familiar to me. Any ideas would be appreciated. This is from the Mineral Wells Dump borrow pit, aka the Fossil Park. Top and bottom, scale bars in mm. Mike

Hi folks, I ventured out today and found these in a creek in Monroe County, IN. I've seen (what I think were) geodized fossils at a local show in the past, so I was keen on trying to find some of my own. Attached are some photos. I think one is a geodized horn coral, while the other appears to be a crinoid calyx or blastoid. There is a small horn coral in some of the photos as a reference. These were somewhat common in the creek. I'm not really concerned about species here as they are fairly distorted, just interested in hearing if you think these are, in fact, geodized fossils.

Been finding a few of these at one of my usual crinoid spots in Northern Kentucky. I think it's just another species of crinoid but I'm not sure. The other crinoid I've been finding here is Taxocrinus whitfieldi.

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

Absolutely stunning coloration. Originally described as Retiocrinus fimbriatus by Billings (1866?) Reference: Ausich, W.I., and Copper, P., 2010, The Crinoidea of Anticosti Island, Québec (Late Ordovician to Early Silurian): Palaeontographica Canadiana, v. 29, 157 p"

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^^^

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.

Ordovician, Nicolet River Formation, Crinoid columnal segments
Denis Arcand posted a gallery image in Members Gallery
From the album: Fossil Art
These crinoid segments look amazing in their natural color -
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
