My daughter found this on our trip last Monday. She has an eye for trilobites and we thought that's what it was. After looking at it closer today, I'm wondering if it is actually crinoid? It's the only one we found like it... Any and all feedback appreciated! Thanks in advance.

Found this piece of float in a place where there is a mix of native scree and fill from God knows where. Due to circumstances I was not able to climb the slope to try to find a source layer. Exposed bedrock I think is Mifflintown Formation. The slab of hash shows three reasonably clear specimens without any prep. Each has a ring with triangle segments pointing toward the center, and one pair of dominant rays running from the center to the perimeter. Someone on the FB group pabe suggested "Cyclosystoid" which I had never heard of, and there is only a little available on google that isn't paywalled. Eventually I'll focus on the other species in the hash to try to verify its Mifflintown and not trucked in fill from who knows where. What do you thiink? (PS thanks for the lead so far, Greg)

Hi everyone, I was out on a collecting trip this weekend around the Fern Glenn Fm, St Louis, Missouri. I came across this which I think is Crinoid related but I've never seen one with the little spikes sticking out. It's about 3/8th inch diameter by about 3/16 inch thick. Can anyone give me any ideas of the species. Thank you

Painted Moroccan Crinoids
MarielleK posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all. I am looking into getting a nice decorative crinoid fossil without breaking my budget. I was considering getting one of the Moroccan ones that are commonly painted for contrast, then washing the paint off. I know these aren't very often completely faked, but are often composited. I have a couple that I am looking at and just wanted to check if they are genuine, and how much (if any) is composite. I would also like to know if you all think they will turn out nice once the paint is removed. I included pictures of two, labeled fossil A and fossil B. Sorry for the blurry photos, it's all the seller provided. Let me know what you think. Thank you!!

I found this on partridge point in Alpena MI in Devonian limestone and have been finding crinoids and blastoids. I’m not sure what this is.

Hi everyone! I have recently acquired a crinoid from an old collection... I have never seen a crinoid of this type before but I think it comes from a famous fossil site maybe it comes from the usa.... I will soon prepare it but before that I need what exact species is that in order to have a mental image of the specimen and so avoid any damages while preparing it .... thanks for your help!

This is from Xingyi of Guizhou in which Keichousaurus is found. It looks like a plant fossil and at the back is fossil of crinoids. Any idea if it is a plant fossil and what plant is that?

I was wondering about this pattern. Thx.

Back in May 2017, I brought back some nice fossil plates from Ohio, I believe Ordovician in age. First photo is plate 1. Next photo (of plate 1) shows a close-up of parts of the trilobite Isotelus, next photo - a nautiloid (unknown species), next photo shows valves of the brachiopod Strophomera, along with many bryozoan fossils. Next photo is a close-up of crinoids on plate 3. (Not much on plate 2). And last photo is of quite a few crinoids on plate 4.

This was another interesting thing I found as a kid in my backyard. There are a few of these on the rock. And theyre definitely not bolts. It is not threading. They are layered rings.

Central PA, Mifflintown-Bloomsburg (undividied) Block collected from roadsite float. Its pretty variable, with a flaky/fissile layers alternating with slightly more cohesive ones. Lots of broken brachiopod bits. For an experiment to I dropped an unremarkable flake the size of a large coin in some vinegar and let it soak for a day. The flake had a couple brachiopod bits and I wanted to see if they would fall free or dissolve in place. The brachiopds disappeared and I was left with this (see pics). Of course I got really excited and thought I had an early fish spine, but now I think I dissolved a crinoid stem and what we see is the matrix that filled in the soft bits. What do you think? Total length is 3/4"

Yesterday, my folks and I decided to head to Ooltewah to get access to property with Missisipian (I think, don't know the formations there by name) marine fauna. It was only a slightly longer drive than it took to get to Chatsworth or Dalton, being maybe 1000 feet north of the GA-TN border. We parked in a big gravelly lot. The first impressions upon arriving were promising: As I expected, we saw this sign on one of the logs leading into the place: With this, the first order of business was clear: finding the owner to ask permission (as always (couldn't find contact info on the internet)). There was a house that was right next to the parking area, so we tried knocking. Nobody home. We then spotted the sign of a taxidermist that was either the owner or their neighbor. So we walked up the road and then up the taxidermist's driveway to go talk to him, and found him prepping some deer skulls. We explained to him that we had heard that the quarry he was next to was a fossil hotspot according to you guys on the forum. He told us that this wasn't new to him or his uncle, who owned the quarry in question. He called his uncle to tell him about us and was very generous to let us in. Before we started, the uncle showed up in his white truck and we had a nice long conversation, with him telling us about university classes coming through the area to hunt the quarry quite regularly, and that a certain group of people had even discovered a few 300 or so year-old native graves with glass lids. All in all, both were very polite and I recommend getting to know them if you do drop by the area. With permissions out of the way, it was time to get to the good part: the hunt. The area was huge, and in the biggest cliff I saw what looked like 5 distinct formations exposed (names/ages pls?). The uncle told us that the best stuff was at the top of the cliff up a shirt dirt road that led to the top, so after a minute or two of looking at what I believe were concretions, I ventured up the road while my step-grandfather stayed below to search. On my way to the top, I saw what I thought at first were a large industrial screws or bolts that had severely. After I saw a few more, I decided to pick a few up: It was only upon looking at the end of these "bolts" that I realized they were bits of Crinoid stem, and then I picked up the one on the far right (is it a bryozoan? I remember seeing a piece like it on FOTM). After seeing 1, I couldn't help but see what must have been thousands of columnals Covering the ground. There were so many of these columnals that you would've needed to be a ninja to not inadvertently step on some while walking around. After We had collected a good amount of marine material, I explored an area where a darker formation was exposed, but didn't find anything in it.

Authentication of Australian Crinoid Fossil (Jimbacrinus Bostocki)
Peter Stahlberg posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! I'm new to fossil collecting (as well as this forum) and have bought my first fossil today. Being completely inexperienced, I thought I'd try asking folks on this forum whether the fossil I bout is authentic. I am somewhat skeptical of this crinoid fossil's authenticity given how well the crinoids themselves seem to be preserved in the substrate. They almost look like they're made out of potting clay and are very crisp. Could anyone with experience give their input? This fossil was a significant investment so I'd like to at least know I got what I paid for! Thanks in advance.

A friend of mine gave this beauty, he found it in Northern Kentucky. It's odd because Northern Kentucky isn't to far away from me, yet I never find them on the river here in Southeast Indiana.

Found this a while back. Not sure, but I think it's a crinoid. Please correct me if I'm wrong someone! Found in missouri.

I found yesterday this -I guess- pieces of crinoid columnals in a Lias (Hettangian) strata. In my area -Pedraforca zone, SE of Pyrenees- Jurassic sites and crinoids are rare (most sites are Upper Cretaceous), so I know very little about them. Tne only crinoid mentioned for the area and period is Pentacrinites. Can you confirm/refute my guess? Thanks.

Real Jimbacrinus bostocki fossil?
FrostbyteFossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Just wanted to double check the authenticity of my Jimbacrinus bostocki fossil crinoid from WA Australia

I have searched since I found this, to figure out exactly what it is. Nobody that I have talked to has been able to for sure ID it. I found it while searching for crinoid fossils at a beach near Michigan City, Indiana, in Lake Michigan. I was swimming around, picking up anything I found, taking a look, and I tossed this one up on the beach. We were guessing that it may be the bulb part of a crinoid, but I haven't found anything online that looks exactly like this one. We used dental tools to pick out some of the sandy stuff, so we could see more detail. My hand is not in the picture for size reference, rather, I had to hold it upright to get more picture angles. My mom took this fossil to a rock show, and people were amazed by it, though they couldn't identify exactly what it is. Some said it is a once in a lifetime find. If it can't be ID'd here, I will likely take it to the university I attend, or a museum. My dinosaur class professor wasn't entirely sure about it either. I would really like to know exactly what it is. Thanks in advance for any help! I look forward to contributing to these forums!

purchased online information unknown sorry they seemed to think it was a claw or perhaps a tail of some thing I am leaning more toward crinoid stem fossil. not sure though have now found any online that have what looks like skin on them...interested in seeing what you people think.

Hi all, I recently made a trip out to Wilson Clay Pit in Brownwood, Texas with my local paleo society. I've found several recognizable things, and a few I need some help identifying. I apologize in advance to @erose who gave me an idea on one bivalve that I failed to write down, and thereafter promptly forgot! I think the tooth is Petalodus sp., just need confirmation. I'd love a genus for the clams, and I have no idea at all what the small plate-shaped fossil is. Thanks!

I never cease to be amazed by the crazy things I find while stumbling around in the great outdoors like this odd remains of a crinoid. Mother Nature keeps me endlessly entertained. The rock has shells, bryozoa and other TBD's. The rock the specimen is in also just really, really light for its size and very porous in appearance. Lots of voids, some with very tiny shells inside. this seeming spiral gastropod is probably 2mm long and hiding in a void. not the best pic as taken indoors with lighting at night...but I hope you get the idea.

Is this a concretion that formed around a crinoid? Or something else? It's approx. 3in.x3in. The bottom half is smooth and the top half is rough. Holes at both ends. Found Riley Co, KS - Flint hills

I am looking for some help on a couple small pieces that I just happened to buy today when I stopped in a small store. I normally would not buy things without proper id’s, but the prices were right. Scale is in inches- The first piece has what I believe are two different Crinoid calyx- the tag stated that it came from Grantsburg, Indiana and it also had “Haney Fm.” Written on the tag. This was on the back of the plate.
