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

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 hid the snail along the trail behind a tree because it was to delicate to carry along. I actually ended up forgetting it, and will have to retrieve it next weekend. Once I got done walking and hit the encrinite rock, I decided to hunker down and look for recently fallen debris. Within 5 minutes I found my nice first possible complete calyx. Only prep would tell if this was complete, but it was worth throwing in the backpack. Looking low was paying off, because 3 feet away and right where the water level dropped was another one. I could tell right off the bat it was an Azygocrinus rotundus. It looked complete, but being lodged upright and inbetween two more pieces of rock, it was almost guaranteed to either be missing plates or extremely weathered. It was weathered, but actually better than I had thought! As I kept going, I kept flipping rock. Its always good to look at the underside of fossiliferous rock, because I've found some nice pieces that way. The next find was found doing just that, and looked to be a complete Macrocrinus verneuilianus. This is what I saw before flipping it over. And the backside after some rinsing in the lake. After throwing that in the backpack, I kept scrounging. Macrocrinus was the most common find of the day, and I found another within minutes. This one was buried in some sediment on a bigger chunk of rock. Can you find it? It will definitely clean up well. I spent another hour or so looking around and also managed to find a nice Uperocrinus pyriformis crinoid and another partial Macrocrinus verneuilianus calyx, but I didn't get pictures of those in the field. I cleaned up everything with soap and water when I got home, but I only had time to prep one crinoid and partially prep another one. Well, heres the calyxs cleaned up. Uperocrinus pyriformis Macrocrinus verneuilianus #1 (first crinoid find after final prep) macrocrinus verneuilianus #2 Macrocrinus verneuilianus #3 Azygocrinus rotundus Macrocrinus verneuilianus #4 And why not end on a brachiopod! Thanks for reading.

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 which side was exposed from its rock tomb. Fortunately for me the half hidden inside the chert was complete, unfortunately though the half exposed from the chert was infilled and weathered away.

Burlington crinoid calyx ID second opinion: Agaricocrinus planoconvexus?
Jackson g posted a topic in Fossil ID
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 keep it to prep later)- 3 replies

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 piece down, I worked around to keep the piece and calyx intact so it could be removed/replaced back in its calcitic rocky home.

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 due to my lack of knowledge on the piece. Would welcome any guess, thanks!

Another search for Burlington Formation crinoid fossils
Jackson g posted a topic in Fossil Hunting Trips
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 pyriformis Actinocrinites multiradiatus Eutrochocrinus christyi Crinoid calyx (chert layer, unidentifiable) Uperocrinus sp? I also found a very unusual blastoid steinkern with an unusually long thin body. It's from Burlington chert, and I believe it to be a Metablastus lineatus steinkern. Will never know though. Well that's all I dragged home today. Hope you all have had a great Thanksgiving today if you celebrate it.- 7 replies

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.

I ended up going out yesterday for a good portion of the day to my favorite creek. I've collected so many treasures here now that I don't mind sharing my favorite creek now, and figured I would show how a normal stream can have more than meets the eye. Of course these fossils are by no means easy pickings, as it requires splitting large slabs of chert. This is the more risky way to collect the fossils as they are delicate steinkerns that can easily break. The chert can also fracture in dangerous ways so I always wear glasses when I split chert, and would be a blind man if I didn't! Well heres a shot of favorite creek, pretty boring looking right? It's a real treat this time, because the water level has never been so low when I've come here. Usually the water is about 4-5 foot high when I walk through this stream, but currently there is only a few inches of water in certain spots of the creek. That means there is a lot of rock I can look at that I've never layed my eyes on. You can see on the bottom left of the photo where I started work on the first chunk of chert. Taking photos is not my forte! It's hard to see (I thought it was a better photo when I was out fossil hunting) but this chunk has a nice brachiopod in the dead center I worked out. While it was nice to see so much exposed rock this time, the timing wasn't. The leaves falling from the trees ended up making my job more difficult as the leaf litter covered many rocks. As I was splitting chunks off the large slab to get to my brachiopod, I was very delighted to see a small associated sliver that had some coral and brach pieces embedded. From much experience, I used my pocket knife to removed some of the terebratulid brach's delicate (paper thin) steinkern, revealing it's small loop support. I can't express how fragile these things are, they usually pop off or just break into countless pieces. I set that nice piece to the side, and continued to split away. Right before I got to my big brachiopod, this little spirifer popped out and landed in my lap, I kid you not. It was pretty dirty, but it did have a nice noticeable bit of it's spiralia intact. Should clean up nicely. Anyway, heres the nice bigger brachiopod I had my eyes set on, freed of the chert. I like this one very much, and considered prepping it off the chert. I ended up working the chert so it will set up by itself during display. I didn't see much wildlife while I was out this time. I did see this cute caterpillar though. I've always had a soft spot for bugs. I think this guy is a Yellow Bear Caterpillar, Spilosoma virginica. I was fortunate, and took a lot of goodies home this trip. Here is what I find worth sharing. Yet to ID this brachiopod. Terebratulid brachiopods with small support loop intact. Spirifer brachiopod with partial internal spiralia Platyceras gastropod (needs cleaning) Actinocrinitidae (I think) crinoid calyxs, I left one embedded inside the chert and again worked this chert so it sits upright during display. Blastoid calyx, removable from its chert home

Hi there, last fossil hunting trip I went on a week or so ago I found some nice fossils and than this. I was hunting some Burlington limestone/ chert that day. Not exactly sure what this is, a possible bryozoan encursting part of a brachiopod valve? I find a lot of pieces of brachiopod valves in the crinoidal layers, where this was laying so that would be my guess. Hopefully it shows, but the entire top side is covered in tiny pits. Thanks for the help, Jackson. I know this was collected from the Burlingtong Limestone. Heres an Azygocrinus rotundus I found about a foot away from the original posted ID piece for formation reference.

Hello there! As it's getting nicer outside and things slowly turning back to normal, many of us are able to go out and enjoy the weather again. I journeyed to one of my favorite Burlington exposures just 10 minutes from my home. As it was so nice outside, I ran into a lot of friendly fishermen. Not unlike usual, its just me there for the fossils! My favorite spot I'm heading to has me walking a few miles before I start to hit the sweet spots. Along the few mile walk there, it looks like the beavers have been busy. You can tell as you approach the Burlington limestone alone by all the bits and pieces scattered along the nearby land. Today I decided to hunt the bank along the shore, and a layer about 10 feet above it. I have had good luck before finding some calyxs eroded out of the limestone by the waters edge, but the layer above requires splitting stone and further prep with air tools. All in all, I spent about 5 hours out fossil hunting. I've got about 75% of the finds cleaned up so far with the air scribe. Been cleaning as I go. A few of them still needs some scribe work, but I bagged a great variety! Species in the first picture. Crinoids: Azygocrinus rotundus, Uperocrinus pyriformis, Aorocrinus parvus, unknown species. Blastoids: Schizoblastus sayi Actinocrinites multiradiatus Very weathered Dorycrinus missouriensis (the famous 5 spined crinoid) Uperocrinus pyriformis Although the focus was on crinoids, I wanted to share my favorite piece of solitary and colonial corals found on the trip as well. I know some of you like pretty, sparkly corals. I like the crystalized caverns displayed in this one. And who doesn't like naturally exposed, colorful coral sections. That's all for this trip. I hope you all are able to get back out there, and enjoy yourselves and nature as soon as possible. Thanks for journeying along!
