Just a note that James Cullison's 1944 monograph on the rocks and fauna of the upper Lower Ordovician of Missouri and Arkansas is now freely available for download or perusal at https://archive.org/details/paper-cullison-1944-the-stratigraphy-of-some-lower-ordovician-formations-of-the This publication has always been devilishly tough to get a hold of. A nice systematic paleontology section deals with the many gastropods and other mollusks as well as the less diverse brachiopods, trilobites, and sponges. The monograph covers the following formations as currently accepted in Missouri: • Smithville Formation • Powell Formation • Cotter Formation • Jefferson City Formation Enjoy and share as you like.

From the album: Missouri Ammonoids, Nautiloids and Gastropods
Here are some more detailed/more lit up areas of the shell and the other half other half -
Location: Missouri Period: Pennsylvanian Formation: Iola Limestone (Muncie Creek Shale Member) (MO) hello! this is my first nautiloid in a phosphatic nodule from this locality and unfortunately the split wasn't desirable, nevertheless you can see the inside beauty of this specimen I know the genus Prouddenites have been found in these phosphatic nodules as the user Missourian happened to have a post from a couple years back showing his specimen the only issue is with mine its harder to see what it is since the outer shell isn't that visible, any tips on identification or can anyone identify it from its internal portions? I can take more pictures if neccesary Most detailed section: in the middle upper section of this piece had a bit of the shell shown from the underside Measurements: when cracked the little middle section popped out, I was fortunate to find it

Anyone Good with Fish braincases/Skull Material? (Some are very incomplete) ( Missouri )
Samurai posted a topic in Fossil ID
Location: Missouri Formation: Muncie Creek Shale Time Period: Pennsylvanian I have found many things in the phosphatic nodules from the Muncie Creek Shale formation ranging from scales, bones, coprolites and in some cases braincases or skull material however I have found very little of braincases and I was curious if someone could identify what they either belong to or in case of specimen #1 if it is indeed a braincase I was also wondering if someone could possibly link me to some material relating to Pennsylvanian period braincases as It may help me to better identify such material Specimen #1 I posted this one to this site quite some time ago but never got a response to what it was but I am not 100% sure if its braincase or just some other bone material or even the aforementioned coprolite Unfortunately for these last 2 specimens they are incomplete due to my inexperience 2 years ago when I first cracked them open. I neglected to collect the rest of the pieces hence why I have hesitated to show them on this site for the shame of losing something potentially scientifically valuable, nevertheless I was wondering if they could be identified Specimen #2 This one is 100% a braincase but i do not know what it belongs too and wish for identification if possible from the fragment i have Specimen #3 I only think the one above might be skull material is due to how it looks similar to my other more obvious skull/braincase that I own here is a photo of the one I'm describing, which i did have all pieces for: -
From the album: Missouri Plant Fossils
I was recently contacted by a specialist who is studying Neuropteris lindahli and identified this section as most certainly being another piece, I have another section here which he identified as another Neuropteris lindahli mislabeled as Pecopteris sp. -
Fossilized Plant Stems? or just cracks in a rock filled with sediment (Missouri)
Samurai posted a topic in Fossil ID
All of these are from the Winterset Limestone Formation and dated to the Pennsylvanian period Found in Missouri I found this in a rock that was completely covered in these structures and had many layers to them Here are a few I decided to take home with me Natural color in daylight (measurements are in the last photo of this specimen): Specimen #2 -
Anyone good at identifying Pennsylvanian Era Plant seeds? ( Missouri )
Samurai posted a topic in Fossil ID
Hello! I happened to stumble across multiple seed fossils while fossil hunting recently looking for ferns and I decided i had enough seed pod mysteries to create this thread in hopes for identification Location: Missouri Time period: Pennsylvanian Formation: Upper Winterset Limestone Specimen #1 I would say this one is the most detailed plant seed fossil i have found so far ( Roughly 4.2mm) You can see the outline a bit better in the photo above Specimen #2 more rounder in shape (roughly 7mm) Specimen #3 this one is also with other plant material (roughly 7 mm) Specimen #4 This one was from a previous hunt but if anyone recognizes it let me know! (9mm) Specimen #5 (3mm)

A chunk of stromatolite i brought home and two I left behind.
Raistlin posted a topic in General Fossil Discussion
Some day I'll bring the two home. But I don't feel like carrying them out one at a time.

Traveling from Minnesota to Texas next week Take I35-W down and roughly following the Mississippi back up. Any recommendations for fossil or paleo related Museums to visit or fossil hunting trips/locales along this loop? I am mostly interested in vertebrate fossil hunting but would really be up for any good suggestions.

Wanted an opinion on whether this is petrified wood or just a rock doing a clever impersonation. I found it in my in-laws' landscape rock at the Lake of the Ozarks in Missouri. Obviously, I have no idea if it originated from that area.

I found this with a cavity on the outside surrounding it. In limestone.

I was splitting open this rock I found near my house on a hill. Most of the fossils here are small clams and crinoid stems if that helps.

Looking for help with this Early Ordovician (Floian) trilobite from the Powell Dolostone of Arkansas, USA. The specimens (GRAY FIGURE below) were identified by Taylor (1968) as cf. Lannacus nericiensis Wiman, but that species (now a species of Megalaspides) doesn't seem like a great match, as the author notes in the paper. In fact, I'm not sure that proper Megalaspides even lived in North America. Last week, an Arkansan found another asaphide specimen (MAIZE AND BLUE FIGURE below) in these same rocks, which may or may not be the same species as the specimens described by Taylor. My question: Could these all be specimens of Isoteloides canalis? That species is already known from the Powell Dolostone in Missouri per Weller & St. Clair (1928) (as Isoteloides whitfieldi, now a subjective synonym of Isoteloides canalis). Or are these instead specimens of a distinct Powell asaphide, and if so, what genus & species? Thanks in advance. 1959 Treatise blurbs for Isoteloides and Megalaspides are in the BLACK AND WHITE FIGURE below. Here's Taylor (1968): https://scholarworks.uark.edu/cgi/viewcontent.cgi?article=3056&context=jaas Here's Weller & St. Clair (1928): https://share.mo.gov/nr/mgs/MGSData/Books/Volumes/Geology of Ste. Genevieve County/V-022.pdf GRAY FIGURE: MAIZE AND BLUE FIGURE: BLACK AND WHITE FIGURE:

I tried figuring out what this thing was but didn't know what to even call it. Found an article the other day that kind of matched it but now I can't find the article or remember what they called it. I think it had something to do with minerals and maybe hot water being pushed up through the crust and solidifying. But I think I remember it saying there was controversy over that theory. It feels like metal it even has what looks like rust (which has gotten thicker since I've found it). It's not magnetic but if you scratch it, it's kind of shiny like metal would be under a painted surface. I also found this in iron county Missouri it's dimension is about 3 in diameter concaved & about 3/8 of an inch thick.
