I found some interesting specimens today I would like a second opinion on. Thinking both of these essentially complete bugs are Eomonorachus intermedius, but I'm not certain as they are both exposed ventrally. #1 After some cleaning #2- the second ventral specimen here is preserved hiding underneath an Isotelus pygidium and is very tiny! After some cleaning I think both of these partials are Eomonorachus as well. Almost exposed pygidium Half exposed cephalon showing good eye facet detail. Thanks for any feedback. -Jay

An enrolled Comptonaspis swallowi I found today. Unfortunately, some of the shell has weathered away. I'm still pretty happy as these aren't the easiest trilobites to collect anymore.-

An intriguing crinoid calyx from the Chouteau Formation of central Missouri, likely Aacocrinus boonensis . I'll clean and ID this specimen properly later this year.-

HI there, We found a horn on our recent trip to the Missouri River in the St Louis area. It appears to be at least partially mineralized. We have found many Bison teeth on the river sandbars but never a horn. We are hoping someone can help confirm whether it is in fact Bison or Cow. Thank you for any assistance with identification! Much appreciated!

Fossil ID…found in Northern Missouri. Lincoln County to be exact.
laurachristine1970 posted a topic in Fossil ID
First and foremost, I’m new to fossil collecting and what an amazing journey it’s been. I live in Lincoln County Missouri near the Cuivre River and have found some amazing fossils. It seems the creek that flows into the Cuivre is CHOCK FULL of “death plate fossils” (sorry if I used the wrong terminology). Being a “newbie” I have many ID’s to request. I will start today with my newest find.

Found what I think looks like a trilobite cephalon in a creekbed, but I'm not certain. It was fragmented, and the shell looks to be eroded away. This creek had a slurry of Mississippian aged Burlington Formation and assumed Ordovician aged Trenton Limestone mixed throughout. I found Mississippian crinoids and Ordovician cephalopods at this location. It looks like it resembles Illaenus taurus, or some other member of the Illaenidae. Any opinions?

Hello! I'm new to this site so I don't really know how it works, but a while ago I found this rock? Fossil? Idk. In a creek bed. I'm located in Missouri near the KC area if that helps. It's about 5 inches long, 5 and a half in the middle circumference.

Well, after a year of searching, I finally found my first trilobite! They are relatively rare in my area (KC), so I’m pretty ecstatic. Decided to take this prep nice and slow, here’s the bug how I found it: Rock is thankfully not really sticky, was able to spend 40 min on this yesterday: As you can see in the last photo, I used my chisel tip to scribe excess material from above where the head might be. I took it down as far as I was brave enough to do so, because I’m worried that the head might be curved upward. I’m no trilobite expert, so any premature guesses on the species? Update possibly coming tonight. Have a great weekend everyone! -Jay

Phylum: Arthropoda Class: Trilobita Order: Proetida Family: Proetidae Genus: Ameura Species: Ameura missouriensis There is some restoration on the front and end tip of the genal spine were the shell had fractured when the rock was split. -
Today I went through some piles of weathering Fern Glen limestone I have outside, and I found the cutest little calyx. First thought was it was a chunk of stem, but after chipping it out of the rock that was definitely not the case. I compared it to some literature I had on hand, and believe it is small Agaricocrinus pracursor crinoid calyx. I Would like some second opinions. Unfortunately I don't have an air abbraider to clean this calyx further and it being so small as well as ironstained makes it tough to photograph well with my old phone, so I will add a couple more photos than usual. Thanks as always. -Jay

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!

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
