  1. Iowa lawmakers: After 500 million years, crinoid fossils deserve recognition. William Petroski, Des Moines register, Jan. 19, 2018 https://www.desmoinesregister.com/story/news/politics/2018/01/19/iowa-state-fossil-crinoid/1047564001/ Yours, Paul H.
  2. Crinoid IDs

    Today while driving around I saw a coin store that also sold fossils, so I thought that I would stop in and look around. Whenever I go into a little store I don’t just like to browse around without out purchasing something to help the small business owner. So I decided to purchase this little piece that was ID’d as Sarcocrinus granilineus from Crawfordsvile, Indiana. The piece appears to be original and nothing added, but I am not sure of the name. I am not a real crinoid collector, but I could not find this species on the internet. In addition, to me the 2 caylx look different to each other.
  3. I was in a local Barnes & Noble last week and was happily shocked to see that a second edition of "Oceans of Kansas" had been released (came out in September). The first one (Everhart, 2006) was a great surprise in its own right. If it had been just a faunal review of the various layers of the Niobrara Chalk, it would have been interesting enough but it covered even more oceans than that. A seaway covered much of Kansas over much of the Cretaceous but it wasn't the same cast of characters from beginning to end. Various organisms evolved, co-existed, and disappeared across that time and the book is an excellent guide to the fossils found and studied up to the mid-2000's. The second edition looks to be a must-have as well. http://www.iupress.indiana.edu/product_info.php?products_id=808653 It's the only thing on my list to Santa. Jess
  4. Crinoid stem with side arm.jpg

    From the album MY FOSSIL Collection - Dpaul7

    Crinoid stem with side arm SITE LOCATION: Harpersville Formation, Coleman County, Texas, USA TIME PERIOD: Pennsylvanian Period (299-323 Million Years ago) Data: A crinoid stem in matrix, with other stem sections. Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form". They live in both shallow water and in depths as great as 9,000 meters (30,000 ft). Those crinoids which in their adult form are attached to the sea bottom by a stalk are commonly called sea lilies. The unstalked forms are called feather stars or comatulids. Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults. There are only about 600 extant crinoid species, but they were much more abundant and diverse in the past. Some thick limestone beds dating to the mid- to late-Paleozoic are almost entirely made up of disarticulated crinoid fragments. Kingdom: Animalia Phylum: Echinodermata Class: Cridoidea
  5. Please identify fossil, seed or rock

    This was found in a riverbed in Indiana three decades ago. I have yet to figure out exactly what it might be. A gem show expert said it was a Crinoid Sea Lilly but it does not really match Sea Lilly photos posted on line. It is 4 1/2” long, 7” around and weighs 320 grams. Thank you so much for your input!
  6. Is this a fossil

    I am wondering if this is a fossil of a crinoid of some type. I found this is a creek in NE Oklahoma. I believe that most stuff is from the Devonian and Carboniferous time. It is in the harder dense material with a conglomerate of shells and other things on top .
  7. Date my sherds from ichnofossils?

    I thought I was joining my husband in his kingdom of Pareidolia when I thought there were mold or trace fossils, which I now know as ichnofossils, on some of my sherds from time to time. I have no idea how long it takes for such fossils to form, and I often don't have a guess as to how old a sherd might be or how long it could have been in the ground or water, but I am changing my mind. I see fossils on my sherds and I'm not crazy (well....)! I hope these examples are photographed well enough for you to see them, too. I'm very curious if this is common and if I can date the sherds according to the fossils.
  8. Fossil book

    What is best book for fossils? What you have at home that you use to check what species? I'm more interested in book that list all species if possible.... some books don't.
  9. crinoid calyx

    good evening this came from a creek in travis county with plenty of volcanic ash fossils and mollusks. Any iformation appreciated
  10. Bulbous holdfasts of crinoids

    From the album Fossils from Arisaig Nova Scotia

    The scyphocrinus were floating crinoids and their holdfast was actually an air bladder that supported multiple stems and calyx.
  11. I think I see a crinoid, but what else?

    I'm getting braver and will venture that there is at least one crinoid columnal mold preserved in this formation. I'm fairly certain, however, that the other two most prominent molds are not of a crinoid. How am I doing?
  12. Disorganized chaos

    Well I got a new phone (Samsung Galaxy Note 8) on Black Friday and was playing with it snapping some pictures. Those of you that have been to my house know that I am totally disorganized and definitely need to organize my fossils. Thought I would share some of the disorganized chaos that is my basement fossil dumping area. This tends to be where fossils go to rest if they do not make it to the glass display cases (3) upstairs where I put the good stuff. But then that is a step up from the ones that never get out of the map drawers and boxes in the garage. One of these days I will get around to organizing things, just never happens to be today....... I suspect my kids will end up having to organize it someday......... (That's a scary thought)
  13. Greetings, I am starting to amass a growing number of loose crinoid caylxes and paleozoic shark teeth (among other things). Currently I am keeping them in plastic containers separated by age (example below), but I am looking for ideas on how to display these, as leaving them in containers is a bit bland to me. One cool idea I saw (but can't seem to find any examples of) was at a show I visited a few years back. The fossils were held up on top of small metal rods the size of a pen, and held in place by small hairlike metal wires. Does anyone have any cool solutions they've used?

  22. I have found a large rock containing a crinoid calyx. I am deciding whether or not to extract the fossil from the rock it is in and if I do extract it, how should I go about doing that? If you have any additional information you can tell me about this fossil please do so!
  23. Fossils And Football

    Two weeks ago my wife and I experienced a wonderful a trip to Iowa for fossils and football. We started the weekend off great by attending the Iowa /Ohio State football game. We are buckeye through and through and being a visitor at sporting event such as this just adds to the ambiance. In preparation for our game, I created 10 necklaces out of buckeyes interspersed with scarlet and grey beads. They were heavy on my neck as I enter the stadium. But each was created for the purpose of finding 10 special individuals to place them on. So by games end, my neck feels the lightened load. My favorite recipient was a rabid Iowa fan whose wife insisted on getting a picture of him with the buckeye beads draped around his neck. This gentleman and I decided to make this necklace a traveling trophy. He keeps it if Iowa wins the next time. If OSU wins, he must find a buckeye fan to carry on our new started tradition of passing the necklace to the victor. Hopefully future recipients can enjoy the camaraderie that the two of us did. I do want to congratulate all Iowa fans for a game well played! The better team (Iowa) won that day. Here is a view of the buckeye trees on my farm in Minnesota that donated their nuts for the necklaces. Spruce trees outline the buckeyes spelling "Go OSU". The primary purpose for putting my football report in with my fossil excursion is to publicize what Iowa does during the time out between first and second quarter. A children's hospital was recently built next to the stadium and a Hawkeye student, through social media, has gotten the fans to take the time during this "intermission" to turn and wave to all of the children pressed against the glass on the 15th story of the hospital. It brought tears to my eyes seeing 78,000 fans providing such pleasure to the many who peared down upon us. Even the Buckeye football players, who are supposed to be discussing football strategy, got caught up in it!!! I am proud of them. My plan initially was to stay in town and participate in our fossil club's trip to a local quarry the next day. But motel rooms that my wife would accept staying at were all booked. As a replacement for some good old Devonian hunting, we elected instead to head to Burlington in search of Mississippian crinoids the next morning. Lodging was not a problem there. Up early, I headed to a quarry site mentioned in some of the research I had done the previous night. It sounded promising on paper. But upon arrival at the quarry , it became apparent visitors were NOT welcomed, unlike what my research said. A sign saying "No Trespassing, Violators will be Prosecuted" greeted me. A sign a little further up the access was visible so I strolled up to see what it said. "You are now on video surveillance" gave me some butterflies in my stomach. I looked further down the lane and a third sign was present just before the gate into the quarry. Of coarse I had to see what it said. To my surprise, the final sign said Take Another Step, The Bead of My Shotgun is on You. Wow!!! I pity anyone that took that next step. My steps were backwards, and I retreated to the truck. As I sat there deciding where to go instead, a smaller sign was peaking out of the weeds next to me and it had the owner's name (Puc) and phone number on it. Do I dare call this owner very early on a Sunday morning? Of coarse!! I think I made the call just to talk to the creator of these unique no trespassing signs. After 4 or 5 rings, long enough for me to second guess my decision to call, someone in a deep baritone voice picked up. I explained who I was and why I was interrupting his weekend. After a long pause he replied that "the government" would stick me with a $20,000 fine if I allowed you into the quarry. Then for the next 10 minutes, he entertained me with what he meant by "the government" and it wasn't good. Quite suddenly, he quit his rampage and exclaimed, give me 5 minutes and I will be down there. I was going to target practice with my pistol anyways. That was a long 10 minutes as I sat in my truck wondering am I going to get to fossil hunt or is he coming to put the bead of his pistol on me. You must know the outcome since I am here to tell the story. A beat up pickup arrived slightly later than expected and a tall strong shouldered weathered man stepped out without pointing a gun though he carried it in his hand. That was a good sign. He reminded me of Jed Clampett on the Beverly Hillbillies Show pictured here for you young bucks who may not recognize him. I was invited into the scale house as he told me about the quarry's history and his gun collection and a little more about politics. No exaggeration, an hour later, Puc finally said I will show you the quarry's rocks. And away we went. My own private hunting grounds with a guide!! Here are some of my finds: After 2 hours, I was enjoying myself tremendously but needed to take a break. Leaning against a 6x6x10 ft rock, I took a swig of cold coffee and as I sat the cup down, I noticed something on the underside of this large boulder. It was a nice crinoid!!! I just had to extract it from its matrix. I thought this will be easy, as I tried to fire up my ancient cement saw. No go! I anxiously waited 10 minutes and tried to fire it up again. No such luck. So out came my chisels and hammer. After 30 minutes of banging away, Puc came over (he was target practicing) to see what the commotion was. I showed him the specimen I was attempting to release from this boulder. My suspicions were that he had no idea what it was, but he sensed how important it must have been to me. I was instructed to quit pounding and he will be back in a bit. A few minutes later, I hear the roar of an engine and then a LARGE yellow piece of equipment came towards me. It was a jackhammer on wheels, dwarfing my pickup as it approached!! Puc asked me to point out the location on the boulder again and then had me step back. With precision, he whittled that rock down, eventually breaking the fossil free without a bit of damage. What a day!! What a find for me. And most importantly, what a new friendship was made. One lonely man and one fossil freak! I promised him that I would be back.
  24. Community on the Half-Shell

    I love finding multiple fossils. I don't just mean multiple specimens in a single rock, I mean fossils that show evidence of more than one life-form. Shells with burrow traces, for one example. Dung beetle balls. Predation marks. And particularly, epibionts. Here I have a fairly ordinary specimen of the brachiopod Tropidoleptus carinatus. Ordinary, that is, until a closer look is taken.... This specimen supported an variety of other critters on its pedicle valve. Whether the epibionts took hold while the brachiopod was alive, or colonized the dead shell, I don't know; I would speculate the former, as the brachiopod is articulated. I think it is likely that the whole living community was buried together by mud. So who's here? Let's take a closer look. We have several examples of Cornulites hamiltoniae. Some are (relatively) large, while others are very small: Two more Cornulites pictures, then we'll see who else lived here!

    The trilobite is super small relative to the crinoid arms. Do you see it?
