This past Sunday, I had about 2 hours to spare, and wanted to look for fossils. I obviously couldn’t go far, so I decided to see whether I might have any luck fossil hunting along the Iowa River right in Iowa City. The exposure there is from the Coralville Member of the Cedar Valley Formation, which is mostly Devonian limestone and Dolomite. The faunal diversity in this strata is not great - some solitary and colonial corals, a smattering of brachiopods and bryozoans, and a few small crinoidal columnals. I had time to check out two locations very near downtown Iowa City, and both within two miles of my house. The banks leading to the river in this area are relatively short (~10-15 feet), but can be steep and/or blocked by dense vegetation. The first location allowed access to the river via a small boat launching ramp. The river at that point is not scenic and the brief stretches of shoreline contain a surprising amount of large discarded slabs of concrete. This must have been near somebody’s favorite fishing spot, as I saw a chair perched neatly on the stones of the shore. I poked around for a bit and found quick collection of some species of the colonial coral Hexagonaria. I assembled the finds for this photo. They are not that well-preserved. I did find it interesting that some pieces are brownish and contained open corallites without intact septa. These were all thin sheets about 10 mm thick. Other pieces were thicker and larger, grayish stones whose corallites were filled in. I didn’t find much else there other than a small patch of some species of the Bryozoan fenestella a beat-up brachiopod and an even more beat-up solitary rugose coral. With only 45 minutes left, I went about ¾ of a mile north, where there’s a rough, worn-out path to the river; a path likely made by people going down to fish. Here I had more luck, finding a place I’ll return to later when I have more time. I almost immediately found two very large rocks with plenty of brachiopods in them. Unless you zoomed in very close to where my fingers touch the rock in the second picture, you are sure to have missed my favorite find. Here it is zoomed in more closely. Both valves of a fairly large Platyrachella iowensis. I was in a hurry and at first was not going to try to get it out for fear of damaging it in my rush. But with just a little gently prying with the pick tip on my rock hammer, the specimen popped out quite nicely. Here are some pics of it after I got it home: I then found a palm-sized chunk of solitary rugose coral. I’ve read that a common genus of this coral in this strata is Cystiphylloides, although I have no real basis to ID this as such. I still had about 10 minutes to pry open a few pieces of one of the large, brachiopod-filled rocks and got what I think is a species of Vinlandostrophia, as well as a few, small brachiopods that are not identifiable (to my unskilled eye).

Hi all! Went on an expedition to Wardensville this weekend to try out some new equipment, decided to go to the Lost river quarry and try my hand at shale splitting. The drive was nice and uneventful. but eventually I made it to the spot. The scree was more treacherous than I expected, has to use my new rockhammer as a pick of sorts to help anchor myself. this was my very first time to this locality, doing anything like this for that matter, so I had no idea what I would find if anything. after scrambling up to the rock wall and looking over the texture my eyes were met with the first find of the day, a trilobite partial sticking out of the rock. I was excited and managed to retrieve this one from the matrix. Pouring over the rest of the surrounding area, I was able to find a couple more trilobites, brachiopods, and some coral material. Following some of the advice from this forum I brought tinfoil to wrap each fossil in. There was a nice family that also pulled up to look for fossils and I spent some of the time chatting with them about the formation and the surrounding area. I will be making a separate post with some of the finds that I cannot ID, and maybe asking for some fossil prep advice. any Fossil ID or suggestions are appreciated as always!

A recent trip to the Madison Group near Yogo, MT turned up a small exposure for Mississippian fossils, mostly small crinoid hash plates but with a few little surprises. I'm still learning about different types of fossiliferous rocks; I believe this was an outcropping of limestone. I tried to locate these fossils in the National Audubon Society's Field Guide to Fossils, but I'd like to get an opinion from someone who knows much more than I do (which, let's be honest, isn't very much ) 01: These were the largest brachiopods I recovered from the site. Perhaps schuchertella? 02: This one straight-up stumped me. At first I thought it was some sort of aquatic plant or coral, but my reference book is pretty limited in plants, and it looks like no corals I've seen. 03: These are very small, but the coloration of this tiny group is what caught my eye. I'm sure the small segments are crinoid, but please correct me if I'm wrong. I have sectioned off a few small fossils in the plate that I'd like to know more about. 03-1 looks plantish, but I had the same issue with this one that I had with 02. 03-2 are so small that I'm not really able to differentiate one mollusc from another. 03-3 is straight-up weird and I have no idea what to make of it. I won't even venture a guess; I just have no clue. A picture of the outcrop. It was small but kept me busy for several hours. Please let me know if I need to upload more pictures. I'm pretty sure I did everything that the multitude of "how-to" posts said to do... Thank you!

Fossil hunting trip to Tontelange (Jurassic of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
On saturday I went on my first fossil hunting trip of 2021 with the BVP. Normally we would visit my favorite quarry "the Romontbos quarry" in Eben-Emael which is Maastrichtian in age, but due some complications that trip has been posponed till the end of September. Instead we went to the SETIM quarry in Tontelange in Belgian Luxembourg which was quite cool as it supposedly only the 2nd that this quarry allowed fossil hunting so everyone was quite excited. The rocks we hunted in this quarry are Jurassic in age, mainly Hettangian & Sinemurian. The lower levels of the quarry also had deposits of the Triassic (Rheatian) but those were not exposed at the moment unfortunately. But I had a great time at the quarry and I was very pleased with my finds. In a few of the quarry walls were used as nesting for sand martins (Riparia riparia) A piece of rock with the imprint left by a coral in it.

Hello friends! I've had some time to sort through, organize and take photos of fossils from my recent trip to DSR. I have also attempted to ID some of my finds using Lindsey's Devonian Paleontology of NY but have found doing so with the bivalves especially difficult, I'm not sure if that is up to me not having experience with then, them being generally harder to differentiate or a bit of both. Starting off with the lophophorates: 1. This brachiopod is a Chonetid, I initially just thought that it was Devonchonetes which is common at the site but looking closer it looked much more like Longispina mucronata to me, would this be accurate? 2. Next, another Strophomenid brachiopod. Protoleptostrophia perplana? 3. Finally, I believed this one was a hyolith based on the shape and size but @Fossildude19 believed this one may be a nautiloid. I'm still inclined to say hyolith but would like to hear other opinions. I forgot to include a scale here but the shell is about 2 cm long and .5 wide . Pteriomorphs: 4. .I don't have much to say about these, they range in sizes but their form looks quite similar, I am not sure if they are the same species or different. Shell 1 Shell 2 Shell 3 Shell 4 Shell 5 6. This one also looks quite similar to the last few but the shell itself seems a bit more elongated. 7. this one although just a partial was the only one of the kind I found and still pretty well preserved which made me decide to keep it, not sure about the ID though. Pseudoaviculopecten? 8. I'm throwing these in here because I also had them photographed although I don't think these are bivalves, the objects have an iridescence to them and lack any shell detail beyond the wrinkly texture you see here, might these be phyllocarids? Will add more photos soon. Any help is really appreciated, Thank you.

Hello all! I found a glacier transported fossil in unusually good condition in Southern New Jersey so I was wondering if anyone could get specific on it as to species and genus. Obviously, it was found severely out of its original formation so I'm not sure we can get any detail on this but I figured I'd try!

I finished prepping this specimen recently, an unidentified Camarotoechia brachiopod. It exhibits an uncommon/rare orange coloration; only about 1/100 of Camarotoechia brachiopods show it. This one, though, unfortunately has some compression damage on the right side, and some of the ridges have pieces missing. The pictures below first show the pre-prep photo (which I finally remembered to take), and the post-prep. Thanks everyone for reading!

I have just finished preparing this nice pair of brachiopods. I am pretty certain that they are of the genus Salopina, but am not totally positive. The genus is marked as one of the most common brachiopods found in the Leighton Fm, as well as being considered a defining characteristic of this formation. Even though they are so common, I really never tire of them. The way these brachiopods were preserved, though, is rather interesting. @DPS Ammonite kindly acquainted me with the fact that these specimens are not internal molds, as I (pretty sillily) first thought. It seems that these brachiopods were preserved as an internal and external mold, and then the internal mold partly imprinted on the external. This would create a fossil that exhibited characteristics of both the internal and external mold. I unfortunately forgot to take a pre-prep photo of the specimens below. The photo was taken with the specimen wet, to provide more contrast. Thanks for reading!

I finally had a chance to organize my fossils from my last excursion to Iowa. The following 5 fossils are new to me and I struck out trying to identify them. Hence the need for some assistance. They are from the Burlington Limestone/ Mississippian of SE Iowa. 1. This appears to be in the shape of a crinoid cup. It is large and fits Cactocrinus imperator which is suppose to have a smooth surface in the Burlington. 2. The left side is broke away. Reminds me of a bellerophon like fossil but can find no mention. 3. There are lots of shark teeth in the upper Burlington. But this looks more bone like. Your thoughts?? 4. This brachiopod is long and skinny and has been broken off on the left side. Most species listed are broader than long, so this one has me confused. 5. I believe this is a brachiopod but who knows!! Flat as a pancake. Can't find an image remotely close to this so maybe crinoidal?? Thanks for any insight.

Hello everyone, I recently received two pieces of brachiopod fossils from Poland, both come from the Eifelian in Grzegorzowice. The first piece contains a number of small productids, I am not sure about the IDs but they do look quite similar to Poloniproductus varians that I have seen come from that area so I am wondering if that is what they are. And the next brachiopod is some kind of Athyrid? I wasn't able to find any similar species from this location. I would appreciate any help with identifying these, Thank you for looking!

What are these fossils and how old are they ?
FossilizedGerman posted a topic in Questions & Answers
Hello! So I found these three fossils and was curious to know about them... one i think is to be a bryozoan branch the tooth i believe to be a cow tooth not sure how old it may be and the last one is a type of small brachiopod its super tiny but again I don't know much about fossils yet but I am ready to learn more ! So if any one knows anything about these fossils that'd be a great help! First 6 pictures are from the riverbed and the last two are from the beach in Lübeck,Germany Thanks!

Hello everyone, A couple of weeks ago while looking through the pdf Devonian Paleontology of NY by Linsley I stumbled upon a very interesting looking brachiopod, This is an athyrid that belongs to the genus Pentagonia which is apparently found in the Mid Devonian of New York. I was immdiatley quite intrigued by this as I have never heard of it and love athyrids especially with interesting and unique shapes such as this one, so wanted to find out what formations these could be in as I would be really interested in finding some, but upon looking the genus and both species up I didn't get any good results. So I thought I would ask here, does anyone have any info on these brachiopods like what formations they could be found in or maybe any other pdfs that mention them, this is very interesting to me and I would really appreciate any help. Thank you very much! Misha

I'm new, both to the forum and to fossil collecting in general. As with my new rock hounding hobby, I'd like to keep my collection constrained to specimins I've collected myself as much as I can. Thus far, I have a couple of moderately-sized brachipods (fingernail-sized), several crinoid stem segments, and at least one as-yet unidentified.

I have just found this microfossil. It is unfortunately incomplete, but the general shape is still discernible. I have two ideas for this specimen, a fish scale or an inarticulate brachiopod. Of these possibilities, I think that inarticulate brachiopod is more probable. The shape, "growth rings", and slight depression in the top lead me to this conclusion. On the other hand, its size, color, and the absence of such brachiopods from this formation, lead me towards fish scale. I am uncertain on both, and could use some help with this one. The specimen is the from the Leighton Formation, Maine; it is Pridoli, Silurian. Thanks everyone for your time!

Hi guys Fairly new to this. Went to an abandoned sand stone quarry near me. Found loads of brachiopods and some criniod stems. But best of all this big clam. It might be hard to tell but theres a big brachiopod under that rock. Please can you share some tips for getting it out safely. Done as much as i feel comfy doing with my fossil hammer and chisel.

Hi All Fairly new to this. I went fossil hunting with my boy on a beach known for carboniferous fossils. We found a ton of brachiopod specimens but also found this. It may be another brachiopod specimen as there is also a brach mold fossil on the other side. But wondered if it might be something different? If its even a fossil at all.

Hello everyone, I recently got some fossils from Russia, some plant remains from Perm Krai where I grew up and a couple of Productid brachiopods from Sverdlovsk Oblast. They are from the Artinskian stage of the Permian period, one is around 2.5cm in width while the other even though incomplete is absolutely gigantic, the largest I have in my collection. I am not great at identifying Productid brachiopods and the Permian is probably the period I have least experience with within the Paleozoic so I have not been able to ID them myself. The large one looks similar to some Reticulatia sp. I've seen online but all of those are smaller so I don't know if that's accurate, the smaller one I have no idea. Thank you for any help, Misha

Just washed off couple pounds of dried mud on my shoes from my outing yesterday to Grayson spot. Was delighted to find another fossil! I have not been able to ID it, first I thought deer heart clam but I see the hinge, is this a Brachiopod?

When I break open brachiopod packstones from South Haven (MI), I usually find three types of tiny to small fragile brachiopod shells more often than any others. These are from the Mississippian Coldwater Shale formation. I’ve been having a private discussion with a fellow forum member, and we’ve come to the conclusion that these are likely all from the same brachiopod. The largest shell in the first photo always bows inward. The shell in the second photo always bows outward. We suspect those are opposite sides of the same half because of the V on the one side and the indent on the other. The shell in last photo is more flat than the other two. And, after reviewing my rather extensive collection of these specimens today, I can verify that the shell from the first photo can be found with similar growth rings akin to the ones in the last photo. The problem is, the farthest we seek to be able to take the ID is a chonetide. It looks similar to a European species called Tornquistia. Does anyone here have any other ideas?

Hello everyone! I recently purchased two fossils, they were both sold to me as Ordovician the crinoid being from Wisconsin and the brachiopod from Illinois. @connorp has told me in a different thread that the dolomites of the region also preserve Silurian fossils and that these look much more like that. Doing a quick Google search I did find something that looks very similar to the crinoid I have, but I don't know enough about these animals or the area they come from to be certain of the ID. Here is the crinoid in question: To me this calyx looked quite similar to that of siphonocrinus both in the gener shape and the plates covering it's surface. Here are some pictures I found online with the region that looked especially similar circled in red: Along with it I also bought this Pentamerid brachiopod which could very likely also be Silurian. Could it belong to the genus Pentamerus?

This past Sunday I found this brachiopod along with several others at an exposure of the Moscow Formation (Middle Devonian) in Western NY. I looked through Linsley and Wilson without much success at identifying it. It is likely an immature specimen, which always makes figuring out an identification hard. I would love to hear your thoughts. Any help is greatly appreciated! Also, while I have your attention, I could use some help differentiating Spinatrypa spinosa and Pseudoatrypa devoniana. Spinatrypa spinosa? Pseudoatrypa devoniana?
