  1. St. Leon IDs

    Here are a few small bits from the Cincinnatian (Upper Ordovician) roadcut near St Leon, IN, that I’m not sure of the IDs. They were all collected from the butter shale trilobite layer of the Liberty Formation. First is what I think may be part of a crinoid? Not positive. Next, I have no idea. Maybe part of a crinoid. A fragment of a conulariid also crossed my mind. Here is a small brachiopod that I picked up thinking it was Zygospira but is definitely not. I’m guessing this trilobit is Flexicalymene, but I know a few other species of trilobites are found here so I wanted to check.
  2. Hi all! I managed to go on 3 large fossil hunting trips this weekend and pulled in easily the BIGGEST haul so far with the most variety as well! The first two pictures were from Mimico creek and the rest were a mix of Humber river and a separate section of Mimico creek. I managed to pull in my second trilobite from the area so that was very exciting! Also pulled a bunch of stuff that I was not able to identify: /\ This was the haul from last Friday night /\ This is the trilobite I found!!! Very excited to have a second one - its been a while since the last one I found /\ This was the full haul for the weekend trip at Mimico and Humber /\ Some Orthoconic Nautiloids as usual. Although it seems that this isn't just the same species I usually find as some of the patterns were much smoother than what I usually find A couple decent looking Crinoid stalks /\ /\ Lots of different shells this time, with a nice range of lined shells as well as 'mussel' looking shells (don't know the scientific names for these ones yet - sorry :/) /\ A close-up of the real nicely defined deathbed of TONS of shells! Unfortunately the hammer I used for cracking bounced off this rock and mashed my thumb in so that wasn't very fun. But its healing up nicely so I'd say it was worth it haha /\ Variety different sizes of coral (if you guys could help me identify which type that would be sweet!) /\ These were the weird ones. I'm not even sure if these are even fossils but I figured I might as well take em just in case - better safe than sorry!! (I am posting these two in identification later!) I was very proud of this haul! Lots of diversity compared to the usual hunt which is nice because I'm kind of getting a little tired of the mountains of Nautiloids we have piling up in the collection Let me know what you guys think of these ones!!! -Em
  3. Presumably, having been tumbled along the robustness of the Knob Creek's quartz bearing country rock of the Hoosier National Forest in the Bartlettsville (North Lawrence Co.) IN area, the tip of the Crown (Calyx) of this large Crinoid appears to have been sheered off at some point to give the observer a view (in crossection) of the inside of calyx which reveals absolutely nothing but Silica replacement of all internal parts. This sample is of the Harrodsburg Formation in the Sanders Group, Lower Middle Mississippian Time.
  4. Help With Iowa Crinoid

    I found this nice little Crinoid calyx at a roadcut near Dubuque Iowa. i was wondering if anyone might know what species. It was collected in the Upper Ordovician Maquoketa Formation.
  5. Arkona Crinoid prep

    Here is a Corocrinus calypso I found in the south pit at Hungry Hollow last fall (southern Ontario, Canada, Devonian age). In the past these were a common find in the Arkona formation, but access to the productive outcrops is becoming rare. I stumbled upon this one on top of the northern end of the pit. Sitting there in ten pieces and eroding away, I was lucky to have found it before it turned to dust. The matrix is more solid than the usual clay which makes up the Arkona so I believe it was weathering out of a concretion. I glued the bits that obviously fit together and it ended up in a box with my other Arkona keepers. Two weeks ago I was looking through the collection and decided to prep one of the nicer chunks. After messing around for an hour or so I realized that everything fit together into one piece. Cool! There are some gaps as the edges are worn but I'll take it. Most of my prep experience has been on E. rana from Penn Dixie which are usually quite sturdy and forgiving (I'm not very patient but luckily have not ruined a fossil yet). With this probably being my favourite find to date, it was time to turn down the psi and take my time. I think it is coming along nicely after seven or eight hours of work. Planning to spend another seven hours on it this week to finish it off. Not a lengthy prep for some, but certainly my longest so far.
  6. Penn Dixie Crinoid

    Does anyone know what part of the crinoid this element is? Is there enough there to assign a genus? It is 6-sided, and each side has a concavity. Pictured are top, bottom, and one side view. Scale in mm. Location & geological context in tags.
  7. I found this fossil a couple of years ago while collecting in the Bardstown,. KY area with TFF member Herb. The bedrock was Devonian, I believe Sellersburg Limestone, Beechwood Member. The specimen is just under an inch and a half long. It appears to be some type of crinoid-arms/stem pieces. I am in the process of organizing my specimens and having this properly labeled would great. Any help with the ID would be greatly appreciated. Thank you.
  8. is this a crinoid ??

    Hi everyone this is matthew again In this fossil I have here I don't know if this is a crinoid flower or just a piece of a crinoid stem can anyone help me ??
  9. Looking For Fossils In Michigan

    It has become a yearly tradition of mine to visit the upper part of Michigan's lower peninsula, around the Gaylord and Traverse Bay areas, for vacation with my family, and I often spend time looking for fossil in the area, mainly Hexagonaria/Petoskey stones, but for some reason they are far and few between. During my time in the area, I have also found a chunk of limestone containing what appears to be the glabella of a trilobite surrounded by what appears to be large, crystalized corals, possibly a Heliophyllum or similar rugose coral, a smaller piece of the same coral, and what seems to be the calyx and arms of a crinoid. Should I be looking anywhere in particular along the shores of Lake Michigan that aren't as well known as some of the popular tourist destinations? Also, are there any areas more inland that are accessible? (i.e. old quarries, roadcuts, etc.) Any and all advice would be greatly appreciated!
  10. Wax, Kentucky bucket list

    My wife and I had a nice trip around the eastern half of the country late May and all of June. Now that I am home, I am busy sorting fossils from various locations....Wax, Kentucky, Green Bay, Wi; Newberry Mich; Grand Haven, Mich. Kennebunk, Maine. Those were places I was able to stop for an hour or so at some locations. I'll give a synopsis another time. Today, I want to share one of my coolest fossils...I wanted to get home to photograph it better. The piece is only about 3/8" across, and 1 & 1/2 in long. It is a crinoid stem, encrusted in byrazoans all around the edge...but the coolest thing is its view from each end. they are quite different. At any rate, here are the cool end shots...
  11. Trilo Bit?

    Here we have a photo of a hash plate which has bits of bryozoa and crinoid ossicles, but is that a trilobite genal spine? The rock is Upper Ordovician Kope Formation or Fairview Formation. Economy, Southgate, McMicken, Mt.Hope or Fairmount members/formations if you like. Lawrenceburg Road cut, Indiana. Thanks all for looking.
  12. The Crinoid Road Cut

    I don't get to go out fossil hunting as much as I would like these days, but I was able to sneak out to a local road cut for a few hours the other morning. It was the day before my birthday after all! A great excuse for me to convince the wife to watch the kiddos for a few hours. This particular road cut is dated to the Mississippian and is full of crinoids! I was literally walking over them. They were everywhere! Upon closer inspection I found that there were a couple of layers that were mainly composed of crinoids. This large slab was laying on the ground in front of the cut. The slab was almost 2 meters in length. Covered in crinoid fragments. Another large slab of crinoid infested rock. Again, it was on the ground in front of the cut. Yet another slab. I finally remembered to put something in for scale... A picture of what I am calling crinoid gravel. If you look closely you can see many crinoid fragments mixed in. This gravel was up a little higher on the cut. The road cut has multiple accessible levels. Here is a sample of some of the pieces I picked up. In my excitement, I started out picking up everything. Then I quickly realized that was an effort in futility. I thought the specimen at the very bottom right of the picture might have been a calyx when I first picked it up, but I think it may be a geode with a piece of crinoid attached. The largest of the "coin" looking columnals (third in the top row from left to right) is over an inch in diameter. With work being crazy, I haven't had a chance to go through everything and clean them up for a closer look. Sorry this photo isn't the best. It's late here and I'm trying to not wake up the family. Its the best I can do under sub par basement lighting. A very nice (and heavy!) hash plate that I was able to manhandle to the truck. Crinoids were not the only things I found. This horn coral was sticking up out of the rubble just waiting for me to come along and take it home! I like how it is coming up out of the matrix. Lording over its domain! lol I also came across bryozoan on occasion. The shale that they are in is very delicate and brittle. It's barely more than clay. I had to handle with care. Overall it wasn't a bad little outing. Any day out fossil hunting is a good day! I picked up much more, a few longer crinoid stems, a couple of small hash plates to practice prepping on, some geological items for my brother who is more into geology than paleontology. I ran into a few brachiopods, but most were not very well preserved or were badly weathered. Ill try to post a few more/better pictures as I go back through things and get them cleaned up a bit. I also have more pictures of the exposure and crinoid layers that I might post as well. Happy Hunting!
  13. Wellll....a successful day today!!! On my continued quest to find all the echies I found something I never really expected to find- Cretaceous Crinoids! It's Isocrinus annulatus. Also found a crushed up Pygopyrina hancockensis, a nice big one. And one sea urchin spine. So a good day in my book!
  14. Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can't guarantee that I will use every image posted, but if I use your image, then I will acknowledge you in my acknowledgements and give you credit for the image. Thank you for your time & assistance! -Elasmohunter
  15. Is this a crinoid stem?

    Is this sample a crinoid?
  16. Hi! Here is a trip report on visiting a locality near Carlin, Nevada (one of our early videos). I'm not sure if what we decided to call "octopus beaks" (see 1:44 and image attached) are the real thing and not just fragments of brachiopods. Perhaps, somebody more knowledgeable can weigh in with the right answer. Thanks in advance!
  17. Hi, here is a bunch of tiny beauties from Texas (Lake Bridgeport). If somebody can help ID the gastropods at 1:40 and a crinoid at 4:20, it would be much appreciated.
  18. Crinoid or Burrow

    Yesterday I broke up a small boulder from an area my town filled in with rock from a nearby road project. I believe that this is Marcellus or Harrell/Brailer Shale. The item pictured is about 2 inches long and completely filled with very pretty little pyrite cubes. Can anyone tell is this an in filled worm burrow or a a filled Crinoid stem? Both things were in other parts of the same boulder. The item in the third photo i cant decide if its a "brach" or a "trilo-bit"? Anyone want to hazzard a guess.
  19. Lumen cast?

    Is this a lumen cast of a crinoid column? Secondly, is it geodized?
  20. Silicified crinoid

    I believe i know what this is, though not the species. But it is unusual enough for me to think others might like to see it. It is a silicified crinoid column found in a road cut near wax,ky. I was looking for blastoids, but was very happy finding this.
  21. Wax, kentucky

    I had a chance to stop for a half hour at a roadcut near wax, ky to look for blastoids. While i didnt find any of those, i did find a cool bryazoan, another creature that may be a kind of graptolite, and a silicified section of crinoid. Thanks to those of you who helped me find the area... it is pretty cool. Sometime i'll be able to spend more time there, and i'm already looking forward to it.

  23. ID 3 species in a Permian themed exhibit

    I just went to this traveling exhibit in a museum in a city where my brother lives that it is about the animals and life in the Permian period and I got pictures of 3 fossils, an ammonite, a trilobite and a crinoid but I don’t know what species and genus they are?
  24. Silurian trilobite?

    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.
  25. Is this a crinoid holdfast?

    I was wondering if this is a crinoid holdfast. Area is 2 cm x 2 cm Found in the Devonian of Indiana, Kosciusko County.
