Found in warren county Missouri several years ago. I assume its s plant but have no idea.

I have no information about the origin of this fossil, except to say that it came from a large bag of pea pebbles purchased at a big box store in the St. Charles, Missouri area. The raised ridge in the center made me wonder if it's a trilobite. There's also an interesting "shift" about midway down the ridge that creates an offset of sorts. Maybe that's the result of settling over time? It measures about 0.75 inch long, as shown in one of the photos.

Found in creek in Silex, MO. I find many formations like this around the area. Fossil or geological? Each hole is about 2cm in diameter.

We've been finding these oddball puffy stars in the Late Ordovician (Sandbian) of eastern Missouri (Illinois Basin), in the uppermost part of the Plattin Group (a Platteville equivalent) or possibly the lowermost part of the Decorah Group (Katian). We've been finding a lot of weird fossils in that zone, including articulated cyclocystoids, but these I'm at a loss on. They seem to be calcite and preserve in the same texture and color as other echinoderm material in the same rock. They vary in convexity and in the presence of a central hump or divot, but there never seems to be a lumen that goes all the way through as far as I can tell. Some possibilities: stelleroid crinoid (but where anatomically? cystoid (but where anatomically? Up for other ideas or insights. Seen anything like this before?

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.

I found this fossil today in the Missouri Ozarks - we find fossils from the Mississippian period here. It is small: for scale I could probably just fit the tip of my pinky in it. We have lots of brachiopods, bryozoans and crinoid fossils around here but I have never seen this sort of interlocking "spine" (I know its not a spine). Does anybody know what this is a part of?

Some Relatively Heart Shaped Fossil Gastropods or Bivalves? In Phosphatic Nodules ( Missouri )
Samurai posted a topic in Fossil ID
Location is in Missouri The area is dated to the Pennsylvanian Formation: Iola limestone formation Subformation: Muncie Creek Shale Member Hello and happy valentines day ! I was re-examining my old collection of Muncie creek shale nodules and found these peculiar specimens Originally I posted an image of one of my larger heart shaped fossils in my member's albumwhere someone mentioned it could be some sort of bellerophontid gastropod but now that I found a second more complete specimen I think it was time to ask fossil ID to get more eyes and possible identifications. Specimen #1: My newest specimen and one I found to be heart shaped This specimen also has some weird sphere like structures beneath it so I took more up close images of it For this specimen there are no other parts of this nodule as I found it fragmented. Specimen #2: (2.3cm) My largest one and the one possibly identified as a bellerophontid gastropod Size comparison between this specimen and the smaller specimen Specimen #3: I think this is just a regular old brachiopod or bivalve but I just wanted a confirmation on such! (The individual is 6mm long) It also died near some fish remains Both halves of the nodule Right side of the nodule -

Location is in Missouri The area is dated to the Pennsylvanian Formation: Iola limestone formation-) Raytown limestone Member I am certain this tooth belongs to some form of fish belonging to Eugeneodontida but I was unable to knock it down beyond that. From the area I have found various teeth from Petalodus, Deltodus, some from Orodus and a few others I however have no real id on this tooth as I plan to add it to my album as a refrence for the future if I find similar teeth like this one. Length of specimen is 16 mm

Any insight or thoughts? Was found in northeast Missouri, in a small creek that connects to the Cuivre River.

Location: Missouri Time period: Pennsylvanian Formation: Rockpile containing rocks from the Iola Limestone Formation Hello! I came across this specimen in the dirt surrounding a rockpile where I usually hunt for muncie creek phosphatic nodules and was wondering if anyone could help me get an exact ID on this specimen. I have found one tooth similar to this last year that I had assumed belong to Orodus. backside of this tooth I will note it has similarities to another tooth I have that might belong to an Orodus, those similarities being the size being almost identical with the root having the same features along with the similar overall shape. tooth by itself from several months ago.

Hard to identify material in phosphatic nodule? Piece of a crustacean? Coprolite? (Missouri)
Samurai posted a topic in Fossil ID
Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale I have been going through some old nodules I had collected from when I first found an area full of these nodules. I happened to find this and was unsure of what it was due to how it was sort of "Shiny" for lack of a better term. I also have some other different phosphatic nodules with similar features and would love to post them here if anyone is interested. I ultimately wish to have some sort of identification for these materials. Some sort of inclusion in this section so maybe it is possibly coprolite? I do not know- 3 replies

From time to time you can find these little guys in these phosphate concretions as well as some pretty cool stuff -
Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale At first i wanted to say some sort of skull material but I am unsure as I do not see many visible bony structures and I am inexperienced in such fields Here are the image links in larger file sizes and if you are on pc you can zoom into them and see hopefully better detail https://postimg.cc/GTvr5dD6 https://postimg.cc/sMTz8nBf https://postimg.cc/cK6WNQYR

Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale From a collection of Muncie Creek Shale nodules Specimen #1: Starting with the best preserved specimen ( I think this is for sure a fish mandible) backside of the nodule Complete nodule More Images: https://imgur.com/a/3rhBqsR Specimen #2: had flash on in order to make it easier to see More images: https://imgur.com/a/7S3iJIA Specimen #3: This one I was not too sure about as it was only half a nodule when I found it, which unfortunately means most of it is eroded and were unable to find its other half It seems to have the general shape of the first specimen I had even though it's missing most of its pieces If I need to retake some images please let me know! I wish to identify what these belonged to.

So I went to a big cave yesterday and the ceiling was about 40 to 50 high in most spots but I noticed what it think are crinoids embedder into the ceiling and look at the world a little differently now. First to get to the cave we had to climb a steep hill and the entrance was about 60 or so feet off the ground and anyway I just found it crazy that even though you could tell that huge layers of the cave had fallen in at different times it's just blows my mind to think that the water level used to be this high and also that must be a long time period right? I mean these things are from ceiling to ground floor making it at least 70 feet deep and so I wonder how can this time period be accurately dated? I don't think it can. Dang that sucks I really wanted to put some pics on here but I can't because only can put 3.9 mb and just one pic is 13mb.....they are really nice fossils too

I've had some difficulty narrowing down the identity on some assorted brachiopods. The diagnostic features may not be preserved but I figured I'd post them here to see if anyone knew. @Tidgy's Dad Any ideas? The first is a single large valve from the Warsaw Formation in Fenton, Missouri (The old Meramec Bridge site). I've been able to track down most species reported from here and identify everything else but this one is harder. The wear doesn't help. The second are a couple o Echinoconchidae valve casts in chert from a creek in Lincoln County, Missouri. It could be residual chert. The area is otherwise Ordovician. 2.8 cm width x 2.5 cm height. 3.8 cm x 3.2 cm

Time Period: Pennsylvanian Location: Missouri Formation: Most likely Winterset limestone Hello! I am currently puzzled on weather or not this is a Conodont or some fragments from Brachiopod. I am thinking it could be broken parts of a shell or broken pieces of a Brachiopods fossilized lophophore supports from a very small specimen! I have not found any conodont specimens from this location yet as I usually do not hunt for them Images in natural file size: https://imgur.com/a/KNeqtZn

Aglaocrinus crinoid? and tiny trilobite pygium
Bonehunter posted a topic in General Fossil Discussion
Hi all! Very excited to find this crinoid on the very edge of a cliff and cleaned it just a little to reveal this tiny 4mm wide trilobite pygium right next to it. Using Missourian's key, I think the crinoid is Aglaocrinus ? The trilobite doesn't look exactly like the pygidiums I have of Ameura so not sure on that one - thoughts? Am I close? Should I try to clean more of the crinoid? The piece is only another inch or two thick. Thanks for any help!! Bone
