Hi, Another ID help question, I wasn't sure if these might be fish scales or plant fossils or something else. These are from Missouri, not sure of the age or more precise location unfortunately.

I collected some trilobites last year that I have now sent out for preparation. Most of the specimens I found were by splitting rock, resulting in some nice lengthwise cross sections but I also did find one ventral and one dorsal example as well. I wanted to make a post here so I can share the before and after results. Will update this as time goes on, and pieces are finished. #1 ventral #2 dorsal Did a small amount of cleaning on #2. Will let a professional do the rest of the bulk cleaning. #3 I gifted this specimen to a gifted preparator. It looks to be a complete, but small Calymenid. #4 the largest Calymenid I split out. This should be a nice complete specimen. #5 has 2 complete Calymenids, in three pieces of stone. The second specimen cannot be seen, but is underneath the split rock in the first image below. I suspect this one will be a tricky and difficult prep job if both are to be cleaned and seen. #6 this Calymenid is small, complete, and somewhat enrolled. #7 the specimen I am most excited about. This doesn't match the Calymenid cross sections shown above. Perhaps a Dalmanatid? I dont think a complete one has been collected here yet, so chances are pretty slim. That's all I've sent out for now. Many of these sections are very difficult to see without certain lighting and wetting, but I tried my best to showcase what I've been looking for in the rock. I look forward to sharing the results with all of you soon!

Would love some help on identifying what's in this rock. Total newbie here and found this site after doing an internet search. I found this rock that was left in the garden by the previous home owners. Not sure where it's from, but we are in Missouri so could be from this area. This looked similar to pictures I found on the web of crinoid stems, but these seemed smoother. Anyone know if this is a fossil or just some neat rock formation? Also, any tips on cleaning/preserving? I sprayed it down with the hose to get off the loose dirt. Thanks for all your help.

I found some interesting specimens as I was probing soft reddish colored Rock (sandstone?) that had been dumped in a field near my house Atchison Kansas. I could be wrong with my assumption is that it's from the nearby Missouri River. A handful of interesting observations pictured here but I'm not sure about. 1) The hard oozy substance on one rock. Is that amber? 2) the half dollar sized impression that looks like it's an Amber upon another rock. Could that be some kind of plant? 3) one rock has a thin black band across it. Wondering what ancient event might be known to cause that? 4) most interesting, I found a few Trilobite looking figures. From what I've dug into so far, looks like they might bea Carolina praying mantis oothecas. I have read that these can be hard, but they feel hard like the rock, or at least close to it. Nearby I did see s momome cotton-like material that look like it could be another stage of this creature. But then again it wasn't very thick and just a little bit of cotton material there. I have the suspicion that perhaps these were more ancient oothecas partially fossilized. But that was only a wild guess. Any insights into any of the above would be most welcome. Thanks for any help you can provide.

A nice crinoid I found on my creek walk today. I will need to do some more cleaning to determine a proper ID.- 1 comment

I haven’t posted a stromatolite in a while. I’ve been preoccupied with biominerals and petrified wood. To see an old thread on stromatolites in my collection, check out the below link. The below stromatolite slab is one of my favorites in my collection because of its composition and formation story. This slab is a breccia created during a Mississippian time-period Impact (large meteor or asteroid) in Missouri that blended Cambrian aged laminar stromatolites with Precambrian aged iron. The close-up pictures below show the EDIT: agatized interdigital spaces of a stromatolite embedded in the iron. The last 5 pictures are at the highest magnification and show the stromatolite patterns and breccia patterns. Mississippian Impact Breccia Slab, Agatized Cambrian Laminar Stromatolite blended with Precambrian Iron, Crooked Creek Structure, Crawford Co., Missouri (264 grams 6.125x3.5x.375 inches): This slab was sold as fossilized coral. I could tell from the pictures that it was actually a stromatolite which I’ve confirmed with two stromatolite experts. The interesting thing is that it is from the Miocene of Indonesia. Both the time period and location make the specimen rare. Stromatolite Slab, Miocene, Indonesia (109 grams 3x2.75x.125 to .5 inches): Marco Sr.

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

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
