  1. Silurian - crinoid vertebra?

    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"
  2. Possible crinoid?

    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.
  3. North Of The Border: Ooltewah, TN

    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.
  4. 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 would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.
  5. 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.
  6. Hash plate with crinoids

    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.
  7. Possible crinoid fossil?

    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.
  8. Crinoid columnals ?

    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.
  9. Just wanted to double check the authenticity of my Jimbacrinus bostocki fossil crinoid from WA Australia
  10. Plant fossil

    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!
  11. 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!
  12. crinoid stem or tail section???

    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.
  13. 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.
  14. Crinoid Concretion?

    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
  15. Crinoid and Petalodus Tooth Help

    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.
  16. Fossil (maybe) in chert

    Okay, this is way, way out there, but it's a maybe. I am sitting on the fence for going real or mother nature. I was strolling around the mountains today. On an Silurian plateau I spied this piece of cherty material with what may or may not be a small crinoid. It is a bit banged up, kind of rusty looking, but seems like an immature crinoid??? Otherwise, a very interesting want-to-be. Material is missing from some areas which would have been helpful and it wraps around the edge of the rock making it challenging to photograph. On the entire chunk of rock there are no other features of note. Size from 8 on the ruler as it wraps around the other side comes out to about 35mm
  17. I recently acquired a Daedalocrinus bellevillensis crinoid fossil plate from the Bobcaygeon formation of Brechin, Ontario. At the bottom of the plate is what appears to be an annelid worm fossil. It is segmented but the segmentation is nothing like the segmentation of any crinoid stems I have seen and is more similar in appearance to a modern earthworm; it also terminates with a point. It also has occurred to me that this might be a frond from a crinoid but I don't know what the terminations look like. Would anyone have any suggestions as to how I might identify this fossil? The picture doesn't do justice to it but the item of interest is the item crossing the crinoid stem. Any suggestions would be appreciated.
  18. It just looked different. I think its a fossil of some kind, is it another Crinoid?
  19. Clarksville Indiana Crinoid Like Fossil

    I was collecting fossils in Clarksville, Indiana today at a site I typically find a large amount of Devonian fossils. Some recent rain had washed out a number of small fossils to easily collect. I collected this fossil without thinking twice, but since cleaning it up I realized it doesn't match any in my identification guide. I originally thought it was part of a crinoid stem, but I can't find any documentation to support that. I've spent the last several hours researching and cannot find a match for it. Now I'm at a bit of a loss and would love some input. Thank you!
  20. I have jokingly told people there are literally trillions of crinoid column fragments in this area but I have only found bits and pieces of the crowns. On Christmas Day, while hiking with my wife, I found what I think may be a potential crown in a rock having lots of column fragments. Thus, my request for some substantiation of the possibility. If this is a crown, I will go back to try and field extract just the portion of this rock having the specimen. I think it would be a good one as a 1st experience for exposing/prepping to reveal more of the fossil. The width of the specimen is just at 2"
  21. Coffee and Crinoids

    While visiting family and high school buddies over Christmas time, I was able to schedule a long awaited meet and greet with Tri State native Dom (Fossil Claw) and made a hop over to Indiana for some Mississippian action at dawn. Fortunately the first morning rays revealed undisturbed, fertile ground free from the scratchings of eager collectors. The ground was frozen and frosted over in the 27F air, so we donned gloves and knee pads for a low and slow peek into the long shadows. A couple Pentremites blastoids surrendered their crowns right away. When Dom asked if I was moving along too fast, “Holy smokes!”, or thereabout, was my response as I pointed in disbelief at a nice crinoid crown poking out of the clay at me. The crown looked fragile, and after a short conference, Dom offered up the best idea to free it from the frozen clay: hot coffee from his thermos. The stream of joe melted the mud away like butter, and I carefully wrapped it up in my knit hat for safe handling and travel. A steady stream of blastoids punctuated the hour of so we spent canvassing the outcrop. Then I dropped to a lower level bench for a fresh crawl. I was shocked to lay hands quickly on a second crinoid crown, then a limestone slab with 2 shark teeth, or fragments thereof, poking through. With a continued parade of blastoids, including some multislabs, we decided to leave some for the next guy and headed home to check out Dom’s collection. This was a great first get together with a fellow collector.
  22. This is not a perfect tooth but it’s all natural and massive. It has a gorgeous mottled blue and yellow color. I’m mostly interested in: crinoid specimens, shark and mammal teeth, and non-Utah trilobites. I’m also happy to look at other offers that don’t fit the above list.
  23. Crinoid stem but is there a Calyx?

    I have looked at this piece for about 1 week and my opinion changes from a crinoid stem and calyx to a crinoid stem and broken gastropod and back. So I will now defer to anyone visiting this post to leave their opinion seeing I can't make up my mind. I have both specimens marked.
  24. Crinoid matrix preparation

    Hi, Can you please help me with what I can do to restore/prepare parts of crinoid matrix that has eroded. This piece has been in the storage for several years wrapped up, and after taking it out for display, I have noticed small sections of the matrix started to come off in fine dust. What kind preparation is needed to seal/restore the light coloured exposed matrix surface to its original darker colour? Thanks in advance.
  25. Trilobite and Crinoid ID

    All right TFF family, my friend who owns a local rock shop is in need of IDs for some trilobites and a crinoid. I think these are probably from Morocco as most of the collection these came from are Moroccan and the trilobite prep looks typical of the area.
