Hello y’all! Since my last brach prep thread, I have actually prepped another brachiopod that I intended to make this thread about, but it turns out that it had been crushed prior to fossilization. I decided that it wasn’t worth writing home for, so I present to you: Project Sticky! Here it is before any prep: Now, the name is self explanatory: the matrix is so sticky, it’s pulling off a layer of shell with every rock flake!!! You can see an area where it pulled off much more than everywhere else: I decided that while this one will be a rough brach, I might as well finish it. I’m still trying to learn, so really this is partially a practice prep. Anyways, here it is after a total of 40 min prepping: Still far from done. Aaand, when I went to hammer some of the excess matrix, this got exposed: Looks like this rock will have a double brach prep. Should make it look more eye-appealing when done. Anyways, I did all this yesterday, and it took about 1 1/2 hours. Didn’t take any pics, but I did paraloid the exposed parts of the main shell. Next update may come tonight, or tomorrow morning. Hope y’all enjoyed this, have a great day!

Well, I’m stumped. Can’t find anything like it in my references. Was found in KC area, likely Pennsylvanian. Thank you so much in advance everyone!

Does anybody have any idea what this is? It's the size of a throw pillow and it's extremely heavy it was embedded in the bottom of the creek behind the house I dug it out.

Identification help requested! In presumable Burlington chert (Mississippian: Tournaisian/Osagean) of east-central Missouri (Lincoln County), USA, I recently came across a mostly moldic chert specimen of what must be a bryozoan, but I do not know what early Mississippian bryozoan would possess such a robust axis devoid of zoœcia, as in the later Mississippian Lyropora. At first I was not even sure it was the bryozoan’s own axis but instead thought the bryozoan was somehow associated with an orthoconic cephalopod. Each photo below is paired with its optical inversion to help visualize what originally filled the mold. Scales in mm. The main reason I feel confident that this whole structure is bryozoan is thanks to a colleague’s find of a presumably related unidentified bryozoan, also in moldic chert presumably from the Burlington Formation but from southwest Missouri, that shows the axis and its texture much more clearly than mine. Here is that specimen, again with inversions. Again I have no knowledge of an early Mississippian bryozoan built like this. (Yes, the axis surface texture looks quite a bit like the texture along the genal rim of some Mississippian trilobites! But it also resembles undoubted bryozoan textures I’ve seen.) Identification help requested! Thanks.

While journeying back out to the Mississippi River, I decided to also stop along the Meramec River in St. Louis. There are exposures of Mississippian aged Warsaw Formation along the river. I passed one, and turned around quickly to try my chances at finding a nice crinoid calyx. There was a lot of rock exposed, but not much of it was fossiliferous. Much of the rock was caked in mud and thick dirt, which made finding anything difficult. After a few hours, I did finally manage to find something worthwhile. It was a nice Agaricocrinus crinoid calyx, exposed in the hard bedrock. Unfortunately, no amount of chipping or pounding was going to get this out of the hard bedrock. Luckily, I had a new grinder in my car I had purchased last week that came with a diamond tipped blade. I had never used a grinder or saw before to extract a fossil from rock, but thought this would be a good opportunity to try and do so. Geared up with my PPE, I used my grinder to put in two relief cuts. Success! The two cuts made it a breeze to knock out with a hammer and chisel. The crinoid is dirty now, but will clean up nicely when I get time to put towards it. I packed up my trophy, and decided to drive out to my campsite for the night. The next morning, I took off to a couple of spots along the Mississippi River. There is a lot of rock along the river and in the area, so research is a must! You could wander around a ton of rock and never find a fossil. I had a secret spot mapped out, and today I was not completely disappointed. I had found the Bainbridge Formation rock I was looking for, though unfortunately there was very little rock exposed. A lot of time was spent carefully scouring the few slabs of exposed stone. Here were a few complete, but weathered Calymene trilobites. Many unsuccessful attempts later, I finally found one I thought that was worth trying to clean up. You can see a small portion of the cephalon exposed. I gathered a few more non photo worthy trilo-bits for my collection, and packed up my finds. I had a long walk back to my car. Once I got back, my curiosity got the best of me so I spent some time picking away at my last exciting find. I carefully exposed it a little bit, but will stop here for now. I am fairly confident it will be a complete Calymene trilobite! A definite happy end to my weekend off work.

Hello, I found this rock in an ephemeral stream bed with what I think is an ammonite and crinoid head in the same rock. I'm somewhat familiar with the local geology and fossils but not 100% sure. It was found in Columbia MO in what should be part of the Osagean series of the Mississippian. Most common rocks in the area are limestone, chert, and dolostone; crinoids are extremely common. I'm a lot less confident on what I think is a mold of a crinoid head (second fossil pictured). I just hope it's not a chert nodule. Anyways I would love to hear other opinions to confirm this. Thanks!!!!

I found this in Holden Mo and there is more of it but don't know what it is
-
These were found in O’Fallon MO in a road cut. I think in the Fern Glen formation. Any help with ID would be much appreciated!
-
Found this a few weeks ago and I'm curious if anyone recognizes what this could possibly be. I'm slowly trying to clean it up but the "shell" is very fragile and bumpy. Perhaps some sort of bivalve?

Found this yesterday in northwest Missouri/Kansas border while looking for arrowheads on the river. was wondering if anyone can help me Id this tooth. I find a lot of bison teeth,coral,cronoids,fossils of sea shells ect. and native artifacts on this spot but never one of these teeth any help or input is appreciated thanks

I collected this plate at an outcrop of Bailey limestone yesterday while looking for trilobites. The crinoid fauna present is limited with Scyphocrinus and Lecanocrinus reported. This slab had a visible larger crinoid dorsal cup exposed on top. The plates that are exposed on the cup match well with Lecanocrinus anna (formerly Alsopocrinus anna). I removed some larger portions of stem, and exposed some free arms branching off of what looks like another crinoid. Any opinion if this is a different crinoid, or possibly just a piece of Scyphocrinus? I know preparation would likley be needed for a confident ID, but I'm more curious if anyone recognizes this as a Flexibilia crinoid.

I was out looking for trilobites, but found an interesting crinoid calyx exposed. I've done some research, and I believe this crinoid is from the Mississippian Fern Glen Formation. At first glance, it looked like it was an Agaricocrinus or Actinocrinus. After a little spit-shine, I then changed my mind to Steganocrinus. I've used my best reference on hand with illustrative plates; Kinderhook faunal studies—V, the fauna of the Fern Glen formation1, by Stuart Weller to compare with. I'm curious what others think. This calyx looks similar to Steganocrinus pentagonus I've collected from similar aged deposits. The bottom of this calyx is a bit compressed/ damaged.

I've got an interesting fossil here and I'm wondering if it is a tooth, and if so, from what animal? It was found on the banks of the Mississippi River around St. Louis, Missouri, thus I have no clue what formation it is from as it could have washed out from anywhere upstream. The folds on one end remind me of dentine folds, and it is in line with being part of the grey, straight, line fossil on the edge of the piece. Also, the foveae around the alleged dentine reminds me of cartilage. Just north of St. Louis, MO, there is a quarry on the Illinois side where an anthrodire tooth was found in Cedar Valley Limestone (limestone & sandstone) -- this is what sparked the thought of it being a tooth. The white rock is chalky & soft, but doesn't seem to react much at all when I scraped dust into vinegar. The brown material seems ferrous & sandy. The grey part is translucent when a light is pressed against it. Sorry, I am not great at rock ID yet. Centimeter ruler is in brown, the grey grid is 1 in squares with 1/4in dots. Some of the high-magnification photos are through a 10x loupe connected to a phone. Let me know what kind of photos would help with ID -- mark particular points you want addition photos from and I'll do my best to get them promptly.

Found these on different sand banks along the Kansas (Kaw) River east of Lawrence. They are definitely fossils, and I believe they are some sort of tooth or molar, but I am no expert. Any ideas or positive ids appreciated! ps: this is my first post measured in metric in photos

I stumbled upon a small patch of Warsaw Formation limestone and found a couple of cool Chondrichthyes teeth. Both teeth were unfortunately cracked/ split in the matrix, and the tough limestone bedrock made removal tricky. The smaller tooth looks like Cladodont of some sort. I can't ID or recognize the bigger toothplate, and was curious if anyone has possibly seen one similar?

Help me name the outstanding fossil deposits of the midcontinent Devonian
pefty posted a topic in Questions & Answers
Crowdsourcing / help request! I'm putting together a review article for the fossil collector community on the Devonian rocks of the American midcontinent, which I've defined as the gray area on the map below plus southwest Ontario. I'm hoping to include a section in which I highlight the midcontinent fossils of greatest renown for each of a number of taxa (list below). (I purposely leave "renown" as a somewhat squishy quality open to multiple interpretations.) I would appreciate (1) your nominations of any midcontinent Devonian fossils of great renown that I have failed to capture in the list below and (2) your assistance in filling in the blanks marked with "????" Thank you! List is below. Microbes: ???? Marine algae: ???? Sponges: Formosa Reef Limestone, SW Ontario Rockport Quarry Limestone, NE Michigan ???? Corals: Widder Formation, SW Ontario Jeffersonville Limestone, S. Indiana Petoskey Limestone, NW lower Michigan Hyolithids: Arkona Formation, SW Ontario Tentaculitids: Arkona Formation, SW Ontario Conulariids: ???? Bryozoans: ???? Brachiopods: Silica Formation, NW Ohio ???? Pelecypods: Arkona Formation, SW Ontario ???? Gastropods: Rogers City Limestone, NE Michigan ???? Non-ammonoid cephalopods: ????

Location: East Missouri Being a really new hunter, this is only the 10th or so actual fossil i've ever found, and it's a doozy. A large death plate that I stumbled upon, that I want to do some prep work on to try and uncover and identify what appears to be some actual fossilized bone. Or even if not, just uncover some of the depth. There's a ton of surface cracks here that i've been gently tapping to work some of this plating off, but i'm more super curious about the general structure here. I've highlighted a few areas that I'm concerned about touching, and would love some feedback. What's my concern? I've noted in the below pictures below, but there is a highlighted area that has a suspiciously smooth texture that makes me worry I am actually going to work on top of or chip away a larger set of fossil. So long as what i'm working with here is just some common fossil of no historic value, I have less concerns, but the size of the mass on the lower right has me concerned to work on this specimen at all rather than turning it into our local Science Center for management. I'd love some opinions here on what exactly i'm working with, and any other general conversation Note: I've pushed the contrast on the fossil-overlay image to help show some of the detail on a hazy day photo. I have included both an overlayed image with some text and the full RAW image from my camera with higher resolution for examination.

Went to look for trilobites at one of my favorite localities. No complete trilobites that day, but I did spot a neat little tooth instead. I did some prep hoping it could be identified, and will finish it soon. I thought the root and multiple side cusplets compared well with Glikmanius occidentalis, but of course I always welcome more opinions. I forgot to add a scale, but the exposed portion of the tooth measures 2 cm in length. as found after some cleaning

Weird Black Shale Fossil+ some conodont teeth fragments (Missouri)
Samurai posted a topic in Fossil ID
Location: Warrensburg, Missouri Period: Pennsylvanian Formation: Unknown Hello! I happened to have had an opportunity to visit land owned by one of my friends and decided to split some of the black shales. I happened to come across something that seems familiar but I just can't seem to place a name on it as of yet. So far I have found 2 specimens, and I'm not sure if one is just infilling of the original mold or something other. Unfortunately they were in already weathered sections of shale and I could not retrieve the other halves of the shales. In case it helps with identifications, I have found listracanthus denticles, conodont elements, very faint orbiculoidia? shells/fragments, and some nodules that were not compacted enough for me to take thin sections of. Specimen #1: What appears to be a mold of the specimen. Very faint shell fragments are visible to the right and upper portion form the specimen Specimen #2: And lastly for anyone who is interested, here are images of the conodonts! Another conodont tooth fragment seen on the left side: I didn't do any size measurements on the conodonts or use the CAI to determine anything as I'm not experienced in the later but would love any input! Thanks for taking time out of your day to read all this!
