    Crinoid second look

    I think this calyx I found today and prepped (on the left) is a Macrocrinus konincki, but I've only found one other one. I typically find Macrocrinus verneuilianus (on the right), so anyone familiar with crinoids please let me know what you think! Thanks, Jackson
  2. So to start the month of May off, I decided to go out and spend my Saturday fossil hunting. The water has been really high lately, so that's put a delay on my usual weekly walks. I decided to go to my favorite creek that has exposed Burlington Formation chert. It doesn't look like much fun, but I sure enjoy walking it. The water was higher than I wanted, but it was searchable so I spent about 3 hours here, and didn't really find all that much today worth taking home here. Most of the good stuff I've found there requires splitting chert, which I didn't partake in today. I only
  3. Hey there, I cannot find anything in my literature/ books on Burlington Formation straparolus gastropod IDs. I can confirm this is from encrinite Burlington Formation limestone, Henry County, one of my sweet spots. It is the first complete one to date I've found there, and I would like to have a more precise label for my first complete straparolus sp. fossil if possible. I can glue/ prep the specimen if needed for an ID, but I would need probably 2 weeks time for that. Thanks for any leads- Jackson G
  4. I had some spare time this past weekend, and a fossil hunt sounded nice. Bad weather had made that impossible the previous month. The weather was great out finally, so I went out Sunday (3/7/2021) to good old Truman Lake to look for Burlington Formation crinoids. I mainly just wanted to find and keep nicer, intact crinoids that day. It's a good walk to the crinoid hunting grounds from my car, and there is fossiliferous chert material along the way. I decided to split one chunk of chert, which contained only one single platyceras gastropod steinkern. After finishing work on it, I hi

    Crinoid calyx cleaning

    Well I have been off of work this past week, and I start back this following Monday. With some of my extra time I've had, I've started work on prepping/ repairing some of my bulk Burlington crinoids that have just been sitting around. All of these calyxs are in different stages of completion, due to me always hoping from one to the other. Starting with one of my favorite species, Azygocrinus rotundus. This piece is mostly completed, I just need to finish working the matrix to however I'd like it. Next we have a mostly complete Uperocrinus pyriformis. When working

    Brachiopod lophophore

    Been staying busy lately, but I had some spare time this weekend so I worked a stockpiled block of chert I had in the garage. I took this block home specifically because of the exposed partial brach sticking out of the hard chert. To reduce the size of the rock, I first split it in half which ended up being a lucky split as it didn't damage the brachiopod fossil or fracture the chert in a challenging way. After splitting the chert, I removed the steinkern from the rock and picked away the intact half of the shell not exposed with a sharp needle in hopes of some golden spirals. Easy to see whic
  7. For those of you familiar with crinoids of the Burlington Formation, (Mississippian) I would like to get a second opinion. This calyx is partial, but I believe there is enough present to confirm my guess for ID as Agaricocrinus planoconvexus? I haven't collected even a partial of this species yet, so confirmation would be exciting. Thanks for your thoughts, Jackson Top Bottom Side shots This other one is probably complete. If it takes me prepping this one to get a 100% confirmation, please let me know and I will do so. (Would rather kee
  8. While I was out today I found a nice crinoid in a big chunk of crinoidal limestone. I decided to take one risky wack to the opposing side of the calyx with my Estwing at the rock, which ended up working out well. Most of the time I wouldn't bother because it never goes this smoothly, but I have a lot of this species so I didn't mind if I busted it. The circular calyx is very reminiscent of Azygocrinus. After splitting the rock, I took the half home with the crinoid. The rest of the work was done with airscribe. I'd say it came out pretty well. Once I had the size of the

    Chert fossil? Unknown

    Hello, I found this yesterday while out searching for crinoids. It's a piece of chert with some weird cylinder shaped thing on the right, and it has a groove that runs through the center. Over a year back I found the exact same thing, except that one was much longer being probably over a foot long in length and again ontop a slab of chert. The one i found yesterday was around 4 to 5 inches I would guesstimate. I've done a lot of fossil searching, and this is only the second time I've ran into whatever this is. Is it even a fossil? Reluctantly, I didn't take either one home on either occasion d
  10. Today's the first nice day we've had all week here, and on top of that lucky I got the rest of the week off of work. I decided to go out and search for crinoids for a few hours. Last time I went out I did recon on a favorite spot of mine, and I would say that effort paid off today. I ended up hitting a new section at the area that is usually underwater. Well anyway, heres the finds. Only about half are cleaned up. Starting with Azygocrinus rotundus Macrocrinus verneuilianus Uperocrinus pyrif
  11. While I was out doing recon on a new fossil spot today due to the lake's low water level, I ended up finding a nice terebratulid sp. brachiopod with its support imbedded atop a fair sized (over a foot and a half in length, about 3 inches in thickness) slab of chert. I took it back home with me, and after a few wacks all was done. I like how this one came out. It sits upright on it's own for display, and it also has a side window exposing more angles of the druzy covered small loop support.

    Halloween hunt

    Goodmorning/ afternoon all! Being a middle aged 20 year old, I've outgrown the need to go trick or treating for candy on Halloween. This year, my brother and I were supposed to have my nephew over for the weekend. We had originally planned some fun activities for the little guy (he's 4) as real trick or treating was out of the question this year. Turns out this week that 4 of his day care workers came down with the Covid, so he's now in quarantine at his mom's house for 3 (her choice, she won't budge) weeks. All alone for Saturday now, I decided to go out and look for the real treats, f
  13. The sun is exposed, snows melting, and many a birds chirping means it's nice enough to go scope out some Missouri Mississippian limestone! With the randomness of the weather this state gets, this is the first chance this year I've had to return to one of my favorite spots. This is one of many Burlington Formation exposures in Missouri. There are spots where the limestone consists of almost entirely crinoidal bits and pieces! Being the picky man I am, I mainly collect and prepare calyxs and brachs. Crinoids are king here, and will be by far the most common critter. They dominated t

    Crinoid Fossil Attempt

    Recently, the opportunity presented itself to me to hunt for crinoids in the Burlington Formation of Des Moines County, Iowa. It was not a scheduled trip, but one that occurred because I in the right place but the wrong time. My mistake gave me a full free day to hunt fossils in Iowa (what a bummer!!) , so I headed out to look for some crinoids. The Burlington is so different than any rock formation that I usually hunt. It is made up of 90% crinoidal remains. It must have been a spectacular ocean floor to see!! I envision it to have been an undersea garden. Fossils other than crinoids do show
  15. This is a new one for me. A neat little button-like horn coral: Dipterophyllum glans from the Middle Mississippian Burlington Fm. of Iowa. Didn't know which forum to share this, so I thought I'd drop it off here for posterity (scale in mm)

    Spirifer subaequalis?

    @Tidgy's Dad, I have this one as Spirifer subaequalis. Location and stratigraphic info in tags. Pedicle valve: ~14 plications in sinus at margin. >20 on either side of sinus at margin (some not preserved). Thoughts?
