Very much an amateur here. Recently some farmland in east Tulsa was scraped off for a new housing addition. I have found lots of crinoid stems and a few shells and trilobites. But I don’t know what this is that I found today. Can anyone help?

sLast weekend I took a four day trip to Kentucky to see family; parents, sister, brother-in-law, and nephew. While there arranged to get together with Herb from the Forum to collect Mississippian Age fossils which I hadn't done before. There are no fossiliferous Mississippian Age deposits in New York and the nearest are in Western Pennsylvania hours away, so this looked like a good opportunity to add some marine fossils from that age to my collection. Fortunately where my family lives is in an area of marine Mississippian deposits. On the way to our rendezvous with Herb in E-Town (Elizabethtown) my nephew and I stopped at a road cut in Leitchfield that he knew about and had seen other collectors collecting at. Fossils were eroding out of the hillside by the score and could be picked up right off the ground free of the matrix. Collected a number crinoid stems, bryozoans, and small brachiopods. After an hour, we continued on to our meet up with Herb. My nephew had already met Herb at a collecting site. We continued on to another road cut collecting site about forty minutes away. Again, fossils were eroding out of the hillside and could be picked right up free of the matrix. Prior to this I had no blastoids in my collection but in just an hour and a half I'd collected fifteen plus more brachiopods, crinoid stems, and some more bryozoan specimens. We then returned to the first place in Leitchfield where my nephew and I visited earlier. Found more specimens including a number of crinoid calyxes, a couple blastoids, and a few more brachiopods and bryozoans. I'll have to study to learn the IDs of these specimens. All in all a great day and Herb was wonderful to collect with and very generous and knowledgeable besides. Hope we get to do this again next year. Oh, and by the way, the family visit went well too.

Hello gang, As promised this is where I will share specimens from my personal collection, my grandfather's collection, and the collection that was donated to the university I work for. The latter is interesting as it is literally boxes of rock and fossils, with no information and my university does not have a geology or paleontology department. I'll be updating it every so often. Enjoy! NOTE: Some of the donated items have old school "labels" on them. If you see initials or such that you recognize, please PM me, as I am doing my best to properly catalog them properly as part of my job!

Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can't guarantee that I will use every image posted, but if I use your image, then I will acknowledge you in my acknowledgements and give you credit for the image. Thank you for your time & assistance! -Elasmohunter

While searching for crinoids a few days ago, I found two items which I thought were especially interesting. Can anyone identify them for me? (Mississippian/Tuscumbia Limestone)

Hey everyone! I have a great selection of fossils at home but I still lack a great knowledge of my most local fossils. I rarely find more than Devil toenails here in the UK but have come across quite a few on my travels today. Initially they caught my eye because they look like my orthoceras but I also have crinoids that have similar markings. There are thousands on the beach with fresh finds every day. If anyone could confirm what I've found it'd be much appreciated. I assume I have a collection of various plant fossils?

Back in January I bought a new 15 drawer cabinet and have slowly been transferring my collection to it. Going through my old finds, some of which have been boxed and/or bagged away I haven't seen for years has been a pleasure and some new gems have turned up that I had overlooked the first time around. There was this Actinodesma erectum, a pteriomorph bivalve which had broken when it was excavated last summer at Cole Hill.

Just signed up (been meaning to for years). Curator of Palaeontology (and geology, and meteorites) at the Ulster Museum in Belfast, Northern Ireland. Published a monograph on Lower Jurassic crinoids 30 years ago (pic of one I found in 1982, at Lyme Regis), and other papers on various aspects of geology from Lower Jurassic ammonites and Strat, through to Mesoproterozoic (no fossils there!) meteorite impacts. But always interested to see what others are finding, especially in the Lower Jurassic. Mike Simms

Sorry I haven’t been around the forum as much for a couple months now but I’m starting to get some more free time recently. Here’s a quick trip @Earth Chemistry and I did a little bit ago. Let’s start out with what stratigraphy we’re looking at here. I’ve been visiting multiple locations of what is locally known as the Gardison Limestone. Source: http://utahgeology.com/utah-stratigraphic-columns/?var=strat_27 It is from the early Mississippian or Early Carboniferous for our international members.

Good Bye to my Crinoid Avatar
crinus posted a topic in Partners in Paleontology - Member Contributions to Science
Yesterday I signed over my prized crinoid (my avatar) along with 20 other specimens to the University of Michigan, Museum of Paleontology. With this crinoid I donated 7 other prized crinoids, 2 blastoids, 4 Tully Monsters, 2 brachiopods, 1 Mazon insect wing, 2 corals and a Cooksonia. These will then be loaned to the Museum of Natural History to go on permanent display in the new museum to open in 2019. Hardest part was parting with my avatar crinoid. It is what I consider the finest example of an Arthroacantha from the Arkona Formation at Arkona, Ontario. Not that parting with 4 exquisite Tullys wasn't hard. Hey, I offered and they came and took. I just wanted the museum to open with very nice examples of fossils.

Hi! Previous weekend me and my friend (paleozoic echinoderms researcher) spent in the quarry near Kasimov (Ryazan region, Russia) where upper carboniferous (pennsylvanian) deposits are exposed. This was an opening of the new fossil hunting season. The main target were echinoderms and especially crinoids. The weather was not very comfortable (+6 C and some rain) but perfect for echinoderm hunting. They become contrast and much more visible when wet. Here is some pictures.

according to the geology, the location is a cross of carbiniferous and devonian period. the location (Crookstown, Co Cork Ireland) is at a meeting point of deep marine shelf environment, marine shelf environment and an alluvial plain environment. The later being void of fossils. if someone could confirm or define what these fossils are, I would appreciate it. also can something be done to clean them up? or a way to safely remove the matrices? the first rock contain what I think are crinoids fragments, there are actually a lot of them here. this is a bit bigger, is it a crinoid as well? Finally the last one, I am actually not sure if it is a fossil or just geological. Thank you for your Help Regards

Hello everyone! My name is Mike. I have been somewhat obsessed with fossils, dinosaurs, and natural history in general from a very young age. I go to beaches on Lake Michigan in Michigan and Indiana during the summer, and like to find crinoid pieces, horn coral, and stuff like that. I also really, really like to take trips to Florida to fish, fossil hunt, catch lizards, etc. While in Michigan, where I live, I like to fish, hunt, fossil hunt, play video games, hang out with family and friends, and get tattoos a couple times a year. I am a senior at Western Michigan University currently. I took a class called Dinosaurs a few semesters ago and it was super cool. I've got a very realistic trilobite tattoo, got it a few months ago. I also have the Jurassic Park Silhouette rex, a realistic velociraptor skull, a realistic triceratops and centrosaurus, the mosasaur from Jurassic World chasing the shark, and a megalodon tooth with a great white swimming, very realistic. I have 11 others as well, but the ones mentioned at least somewhat relate to this site. I have some fossils that I will post for help identifying. My whole family likes to fossil hunt. I went to New York with family last May to find trilobites and other marine fossils at Penn-Dixie Fossil Park. Very cool place, and I highly recommend it. I'm planning on making a trip south sometime in the near future to find shark teeth and anything else around. Well, enough about me. I hope to meet some cool people on here and see some interesting finds!

It’s winter and time to explore as many canyons as possible before it gets hot here. As always; in search of exercise, fossils and other items of interest. A visual summary of the ascent of one side canyon and the descent of the another. The entrance to the two canyon loop Today I had to share the trail Ordovician formations with small cave Ordovician staircase walkway in canyon bottom, Silurian cliffs at top of pic As the main canyon ascends, the hiking eventually meets where Ordovician contacts Silurian At the top of this Silurian dry falls is the Devonian but not much of it. This Devonian area is just before the canyon splits into two canyons

Any clue what this is? It's about the size of a quarter, but thicker. It was found on a Lake Erie beach in OH (30 minutes west of Cleveland, OH). Most fossils from this area are from Dovinian period. It looks like a bunch of shells stuck in chocolate. Are these crinoids?

While @UtahFossilHunter was out for a quick bike ride yesterday, he stumbled across a wash that's been cut by a road. The upper part of the wash above the road is on private land that we do not have permission to be on yet. We had looked at the downstream part of the wash area for fossils before but had not found anything. After some melting of snow and construction, that happened over the last couple days some rocks had been pushed downstream. We decided to look at this wash once again and found these! This is a significant find because it is within 5 miles of my home. Our usual spot is 50 miles from my home so this is great news.

I have managed to find some fossils I want to preserve such as these ferns and some cordaites. As best as I can read online it seems these should not be cleaned to ensure to not ruin them. Or is that wrong? Is there something to soak them in that won't harm them? Afterwards, what is best to preserve them with? Should they be kept away from sunlight to reduce fading? Basically, would anyone recommend a link or two to read to keep these looking nice. Thank you, Kato ===================== Ferns Cordaite with multi-color staining from different oxidization rates from pyritization???

Hi, I'm visiting my niece who just had a baby, in campbellsville KY. I noticed there are a lot of very ancient fossils in Kentucky. Does anyone have any sites or road cuts to explore? Thanks alot, this is my first post. Stuart

Hi, we are from middle TN. While walking down a creek bed, me and wifey were surprised to see crinoids (at least that's what we think they were) every few steps. That renewed our interest in fossils and paleontology. anyway way. thanks for the great resource here.

Dear TFF members, I need help with confirming the age of fossils I have found during the trip to the chalk mine in Mielnik. These specimens were found in the slopes and on the road leading to the mine, so a few tens of metres above the chalk deposits. I have read about the Ordovician deposits streching from Białowieża to Mielnik, so maybe they indeed come from this time? The specimens comprise corals, crinoids and brachiopods. I will appreciate your comments/ suggestions.

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?

I enjoy fossil hunting whenever I can. Looking for sites, roadcuts and field trips. So glad I found this group!
