While visiting family and high school buddies over Christmas time, I was able to schedule a long awaited meet and greet with Tri State native Dom (Fossil Claw) and made a hop over to Indiana for some Mississippian action at dawn. Fortunately the first morning rays revealed undisturbed, fertile ground free from the scratchings of eager collectors. The ground was frozen and frosted over in the 27F air, so we donned gloves and knee pads for a low and slow peek into the long shadows. A couple Pentremites blastoids surrendered their crowns right away. When Dom asked if I was moving along too fast, “Holy smokes!”, or thereabout, was my response as I pointed in disbelief at a nice crinoid crown poking out of the clay at me. The crown looked fragile, and after a short conference, Dom offered up the best idea to free it from the frozen clay: hot coffee from his thermos. The stream of joe melted the mud away like butter, and I carefully wrapped it up in my knit hat for safe handling and travel. A steady stream of blastoids punctuated the hour of so we spent canvassing the outcrop. Then I dropped to a lower level bench for a fresh crawl. I was shocked to lay hands quickly on a second crinoid crown, then a limestone slab with 2 shark teeth, or fragments thereof, poking through. With a continued parade of blastoids, including some multislabs, we decided to leave some for the next guy and headed home to check out Dom’s collection. This was a great first get together with a fellow collector.

Eurypterid or sponge bored orthocone? Revisiting a Mississippian puzzle
TqB posted a topic in Fossil ID
A while ago, I was convinced that this was an orthocone with possible sponge borings though it was never really resolved. http://www.thefossilforum.com/index.php?/topic/77979-strange-infestation-on-orthocone-shell-mississipian-ne-england/& @Al Dente suggested eurypterid as a possibility which I argued against, largely because they've never been found around here. However, a friend of mine has now found some undoubted eurypterid fragments in equivalent beds in Scotland, 120 miles away or so and where the faunas have much in common. He's pretty sure that this is indeed eurypterid (based on just a couple of closeup photos). I'm rather hoping it is though the boring sponge is also pretty interesting. Searching throws up Adelophthalmus as a distinct possibility, based on the ornament (see reference and drawing at the bottom of the post). So here it is again - eurypterid or bored orthocone? Brigantian (Mississippian) marine shale, Co. Durham, NE England. (Many more photos on the original thread, including very close up. The little rings are preserved in solid pyrite and go right through the shell/carapace.) From this paper on Pennsylvanian Adelophthalmus https://www.foss-rec.net/8/3/2005/fr-8-3-2005.pdf

Hi, while on a walkabout for crinoid calyx found this particular formation having what seems to be a branching bryozoan fossil. This particular formation seemed to be quite full of fan type corrals as well as what I think are branching bryozoa (most in the length of 4"-6"). This one was about 4" long. Would someone kindly confirm the fossil type or please guide me to a correct naming?

Fern Glen rugose corals. I need some help/information.
Raistlin posted a topic in General Fossil Discussion
Does anyone have any information on the roguse corals found at the Fern Glen formation? I can only find one but the ones I have found there look nothing like the one in the photos. Mine all look like the "normal" tornado shapes. The Fern Glen is Mississippian. Here is the photos I'm talking about Amplexus sp. http://www.lakeneosho.org/Miss48.html I just did a prep on one (maybe my best prep yet) it's just a common and not even a good specimen, but I tried some different techniques. I'll post it tomorrow after everything dries and sets in. It turned out better than I thought but I will welcome critiques.- 2 replies

The first is from the Menard formation the last two are from the Golconda fromation. https://imgur.com/a/8g5R86m I've been away for some time (life keeping me busy). I have a brand new prep room soon I will have other photos of my room and various fossils and rocks. Members that have been around awhile might remember me and to all you new folk I want to say hello (maybe I should have started with all that). Anyway I hope to be able to get back to posting again since things are starting to settle in.

I spent a few hours fossil hunting on two separate trips on Forest Service land in Montana. The first trip was this past spring looking for Late Oligocene - Early Micoene flora about 90 minutes outside of Missoula. The second trip was during at stint over the summer at a fire lookout tower in the Flathead where I spent just a few hours one morning looking at Devonian and Mississippian marine layers. Besides the obvious, the trips were quite different. The spring trip was a drive to a road cut on a Forest Service road while the summer trip was a seven mile hike in. Additionally the medium is completely different; flakey, brittle shale compared with big, blocky limestone. You can keep non-vertebrate fossils as long as you don't plan to sell them. Prior to heading to an area, I look through publicly available research, lectures, field trips, etc. to find possible localities. I only found limited information on possible identification of the Late Oligocene - Early Micoene flora and most of if was unpublished graduate work from a nearby site with only some overlap on species. Please feel free to correct any id's or throw new ones out! I believe these are cercocarpus, a mahogany.

Hello! New to the forum and plan to introduce myself properly later- I've spent a lot of time hunting in Southern Indiana near Bloomington and at the St. Leon cut- going to Indiana Caverns tomorrow and wondering if there's any spots nearby to hunt for fossils. Spatial reasoning is not my forte- if anyone has specific directions to a great spot I'd be so grateful! On break from teaching art to my high school students- would love to make some great finds over my break to show my kids

I recently came across some "old" fossils I found a few many years ago, which included some slabs of fossils from the Imo formation in Van Buren County, Arkansas. The site is an abandoned phosphate mine known as the Peyton Creek site. It is about 0.5 miles east of highway 65, and there are also some exposures of the same rocks along the highway roadcuts nearby. The Imo is upper Mississippian and is sometimes included as part of the Pitkin limestone. It is apparently an outstanding site for cephalopods and ammonoids, but I didn't know that back then. The slabs contain several small trilobite pygidia, and below is a photo of the best one (about 5mm wide) along with a couple of others (now you have to look for them ). I was going to post here to see if I could identify the genus and possibly the species, but I think I found my answer already. I decided to post anyway, as a reference and to hopefully confirm the id, although I doubt the pygidia alone are enough. I believe this is Paladin imoensis, as I just discovered that the holotype was collected from the same abandoned quarry.

Longtime lurker here. As my first post, this will be a trip report about mine and @UtahFossilHunter 's attempt to find the rumored fossils on Stansbury Island in the middle of the Great Salt Lake. The island isn't quite known for having fossils but the rocks are the right ages for this area. First, we consulted a geologic map of the area we wanted to look through. We used this map from a dissertation of a student at the University of Utah. We decided to go to the undifferentiated Mississippian this time. We had gone out to the area a few times. We had gotten skunked on the Ordovician Garden City Formation and undifferentiated Cambrian in early February. Although, it had a nice view so the hike wasn't for nothing. Both of those formations were empty of macrofossils. (Microfossil analysis coming soon!) So we went to an adjacent valley where a grassy hill sat where the undifferentiated Mississippian would outcrop. We saw a outcrop of phyllite but staying hopeful, we hiked to it looking for any fossils. At the outcrop, I flipped over a rock from one of the beds. Lo and behold, at last, some fossils, albeit slightly metamorphosed. This layer and only this layer is filled with bivalves and brachiopods. We grabbed some sizeable chunks and made are way out. Stay tuned for more progress on research here.

I found this rock in a middle Tennessee creek. (Mississippian, St. Louis Limestone & Warsaw Limestone) I thought it had a brachiopod imprint, but haven’t seen one with such a deep, almost rectangular indentation on one side. Any thoughts?
-
I found this small chunk of rock in a middle Tennessee creek today. (Mississippian, St. Louis Limestone & Warsaw Limestone) It has a bit of a sparkle to it. Can anyone identify it for me? @ynot?
-
I found this little rock in the creek that borders my property several weeks ago. (Mississippian, St. Louis Limestone & Warsaw Limestone) For some reason, it is one of my favorite finds thus far. Is it a brachiopod embedded in a piece of coral or sponge?

My husband found this in a middle Tennessee creek this morning. (Mississippian, St. Louis Limestone & Warsaw Limestone) Is it a type of fossilized crinoid calyx?

I found this rock in a middle Tennessee creek this morning. (Mississippian, St. Louis Limestone & Warsaw Limestone) I would like to know if it is some type of fossil? If not, which type of rock/mineral is it? I’ve seen somewhat similar rocks around here, but nothing quite like this one.
-
Here is another rock which I found in a middle Tennessee creek. (Mississippian, St. Louis Limestone & Warsaw Limestone) This one also has a lot going on within it. There are several fossils I’d like to have identified, but am most curious about the area I circled in red. This rock had a lot of algae (or moss?) growing on it. Is the area which I circled even a fossil?
-
Here is another rock from a middle Tennessee creek. (Mississippian, St. Louis Limestone & Warsaw Limestone) It is full of tiny brachiopods, bryozoan bits and maybe a few other fossils. I would like to have the area circled in red identified.

I found this rock in a creek in middle Tennessee. (Mississippian, St. Louis Limestone & Warsaw Limestone) @Bobby Rico Using your iPhone macro lens tips, I was just now able to magnify an area of this rock which I’ve been wanting to know more about for a while. (I wasn’t aware of the zoomed-in magnifying technique, so thanks for posting!) I’m thinking it is a cluster of three crinoid stems?

Can anyone help me indentify what these are? I’ve found them on a few of the rocks we’ve found, but haven’t been able to figure it out so far. They were found on a bluff in Boone County, MO, in the same area rife with the Crinoids we’ve been finding. I’m thinking from the Paleozoic/Mississippian Era? These are the clearest pictures I could get tonight but, if more are needed, I’m happy to take some in natural light tomorrow. Thanks in advance for your help!

While I find interest in every fossil my daughter and I find, I’m feeling a bit frustrated at finding only Crinoids. Yes, I think they’re cool, and I don’t want to be ungrateful, but I’m getting a bit discouraged.. I’d like to find something other than a Crinoid. Now, admittedly, I only know certain places to look, so that’s why I’m reaching out for help. We’ve primarily looked in creek beds, and along the trails we walk. I’m in Boone County, MO. Can anyone give us any tips on other places to look where we might find something other than a Crinoid? We’re new to fossil hunting, so honestly any tips you have will be well received and we’d be so grateful for them. Thank you in advance. (photos for attention.)

I found this rock in a creek in middle Tennessee. (Mississippian, St. Louis Limestone & Warsaw Limestone) It caught my eye because there appeared to be a hole in the rock. After getting it out of the creek and cleaning it a bit, I’ve noticed the “hole” is actually an indentation in the rock with several raised lines around it. I’m wondering if it could be a crinoid? Also, the other side of this rock had another area I found interesting. Any thoughts on what it could be?
