It's been a long time since posting a trip report, but it has been a fairly active year despite the monkish silence as I try to be fairly circumspect about locations and where I am going. Last weekend was Thanksgiving up here, but I passed on turkey to spend some time solo far from home. Some very nice finds for two days from the Bobcaygeon Fm of Ontario. Time to share. First up, some field shots from the phone. First blood was a doozy. Within half an hour after sunrise, a cluster of Ceraurus globulabatis and Gabricerarurus dentatus. Not the nicest material, but I kept all the bits. There may in fact be more buried in this plate. It got a bit rainy, but I was undeterred. The rains eventually stopped and I kept at it for another 9 hours. Here we have a scrappy Calyptaulax callicephalus. Seriously exfoliated, and a bit too delicate on a flake to extract complete. It would not be the worst heartbreaker of this trip. Getting warmer to maybe finding a Ceraurinus marginatus. This is a wide pygidial array of spines of roughly 2 inches wide. The three individuals on the left are Raymondites, with a scrappy Flexicalymene senaria on top, and that same Calyptaulax photo-bombing this image. (continued)

Hello, I've been wanting to showcase my ongoing collection publicly in some way, and with what I've amassed so far I've decided now would be a good time to finally start. As the title suggests, this collection is dominated by echinoderms and primarily crinoids. These are without doubt my favorite group of fossils, as in my opinion not only are they aesthetically beautiful due to their elegant composition of regularly interlocking calcareous plates, but the highly modular nature of their body plans seems to have permitted an extraordinary variety in form, which is a marvel to behold. With each entry I'll try to add an interesting description or at least factoid about the specimen, species or locality; hopefully this will be a great opportunity for me to do more in-depth research on my fossils well enough that I can explain coherently. That being said, I'm absolutely an amateur and have been collecting for just around 2 years at this point, so I would love any input and corrections from those more experienced. I love any opportunity to talk fossils, and even better if I learn something I didn't know previously. My goal is to make entries semi-regularly. The inspiration for this thread is definitely @rew 's incredible "My trilobite of the week" thread; I recommend you check that out too!

Collecting trip to the world-famous Walcott-Rust Quarry
Nautiloid posted a topic in Fossil Hunting Trips
Howdy! Last week, @KompsFossilsNMinerals and I were invited by Dan Cooper to go collect the Walcott-Rust Quarry this week, so today we both got up bright and early to make the trek out to the central Mohawk Valley for the day. After fueling up on some pancakes from Denny’s, we made the last leg of the trip to the site, which is far from easy to find or get back to! It wasn’t long before Chris and I had both found a nice crinoid calyx, and the day just kept getting better! I mainly surface collected in the piles of weathering rock around the quarry, while Chris and the rest of the guys worked to get down to and peel up some more chunks of the Ceraurus layer. I had heard that the site was pretty difficult at times, so my hopes of finding anything weren’t too high, but not one of us left home empty handed! Collecting at this site has been a dream of Chris and I’s, so this was such an amazing opportunity for us!!- 13 replies

Any tips on preserving this specimen I found over the weekend? I'm happy with the aboral side but I'd like to uniformly remove a majority of the sediment below, which is loose enough to scratch off with a fingernail. However, avoiding damage to the fossil is obviously of utmost concern... is there something I can safely apply to the fossil surface to prevent stress cracking?

Fossils from the middle and upper Santonian of Gelsenkirchen / NW-Germany
rocket posted a topic in Member Collections
In 1995 (long ago...) a friend of mine and me digged at a highway-constructionsite in nw-germany. It was the Highway Nr. 2 between Gelsenkirchen and Gladbeck in famous Ruhrgebiet-Area. The construction site opens at a lenght of 3 km sandy sediments from middle Santonian, Zone of Uintacrinus socialis. We really found a lot..., beach sediments with everything from plants over echinoderms up to vertebrate fossils (some lang-living ones...), and stored it. Till now. Some weeks ago I started to clean, glue, sort..., to write a paper about it. Hope to finish in 2025, lot of work... I go to show piece by piece fossils from this site, might be one a day, might be one a week. depends. Start is a nice Cretalamna appendiculata, approx. 2 cm long, root is a little bit damaged.

Hello everyone! I have been picking through microfossils from the Whiskey Bridge locality on the Brazos River in Texas. I used the hydrogen peroxide technique to separate the fossils from the glauconite matrix, and I have spent hours at the microscope, picking through the material to find the really tiny stuff. Here are a few batches that I've separated... My reason for posting this in the identification section, however, is that I have been running across a large number of echinoderm fragments and spines... The largest of the fragments are approximately 8 millimeters across, while the longest of the spines are 6-8 millimeters. Does anyone have any information on echinoids from this locality? I'm sure others have run across these before. Any information is much appreciated! Daniel

Large plate of Eocrinoid Ascocystites, needs a closer look
Biotalker posted a topic in Is It Real? How to Recognize Fossil Fabrications
There is a plate of 30 or so of the ascocystites being offered for a rather princely sum. Stated as collected near Kaid Errami, Morocco. Here is the entire plate and a close up. It looks un-fossil-like to me. Seems unlikely, but could they be real?

Visiting the Osha Canyon Formation in the Jemez Mountains, New Mexico. Upper part of the formation. The massive sandstone is the Sandia Formation. Underneath is the Pennsylvanian Osha Canyon Formation. FInds: Crinoid stem segments, a rugose coral, a couple of echinoderm plates, and a worm burrow cast. Whole bed of brachiopods: Composita brachiopods? I was shown this site by a semi-professional geologist who calls it The Nursery because there are huge numbers of unusually small brachiopods. Spirifers? some are silicified

Today was supposed to be a day of grinding away at my piles of homework that have been accumulating over the course of last week (hey, I was on vacation what can I say)...and I was almost successful, save until 3 pm rolled around. Getting a little stir crazy, and in desperate need of the fossil hunting fix that I missed out on over the course of my week long vacation + the week of snow we had prior, I set out to take a "small walk" to an area of a creek I hadn't scouted before. My intention was just to do a little bit of reconnaissance - I saw on a geologic map that this particular portion of the creek may expose some of the productive Eagle Ford formation, implying that I *might* have a chance of finding an ever locally elusive Cretaceous shark tooth. A 10 minute drive found me at the park which serves as an access point. It was clear that nobody frequents the area once down at the creek. The creek was virgin, at least here. Furthermore, the ram horn oysters which made their appearance along the gravel banks suggested that I was in the correct exposure. 20-30 minutes in, I find my first Echinoid...ever! It was fairly weathered by the creek, and a little small, but I'm not a man to complain - this is celebration worthy by my terms. Here is that first find, rinsed off. The burst of energy moved me forward through the thicket. At this point, I was on an "island", where the creek had wrapped itself around a little piece of land that had become quite overgrown. Within another 20 minutes, I made my next discovery - another (highly weathered) echinoid with a blobby, uneven pattern on it not too different from a sand dollar. It's difficult to make out details with a camera, but I tried nonetheless. The top arm is the only easily visible portion of the pattern. An hour or so passes, and evening is descending. My final find came in dim lighting, shining proudly out of it's bank where it was half buried. Oddly enough, the best preserved portion is the portion that was sticking out of the ground. Break dancing moves rapidly followed. And so, my evening came to a close. Another highlight was where my heart outright exploded out of my chest glancing at what I thought to be a marine reptile tooth. A second or so of looking, though, deemed that it's probably just a small, slightly weathered rudist - a cool find none the less! Finish that off with a uniquely red ram horn oyster (remnants of original color? Or just fossilized in an interesting mineral environment?) and my day came to a satisfying close. Now to get back to my calculus homework that I've been so diligently procrastinating :''D

So I had a few hours off the other day and decided to hit a favorite spot in the Glen Rose Formation. The Glen Rose is Lower Cretaceous (Albian) and can be very fossiliferous. For those familiar with this formation the particular layer I was hunting is near the top of the Lower Member in what is known as the "Salenia texana" zone. As the name implies it is abundant with the echinoid Leptosalenia texana. But it also produces another handful of echinoids, some common and some rare. I was hunting(hoping) for the rare ones... Now let me tell you it has been a long hard summer and this week was the topper with my wiener dog Bacon getting snake bit in the back yard and things at work being extra hectic and, well just life in general in this time of plague... So I was DUE BIG TIME for a good hunt. Within the first five minutes I knew it was going to be good. We recently had some good rain and there were no footprints in sight. And it was bright and clear and perfect "urchin" light. Some of you know just what I mean by that. Sharp clear sunlight at the right angle makes those tubercules pop, even when half buried in the marl. My first good find was a fossil I had been looking for for a while and one that I got skunked on at the last PSA field trip. Jamie Lynn and a few other club members found them and I was teasing them about it. It was a comatulid crinoid cup. Not an echinoid, but another weird echinoderm. Comatulids are stemless crinoids, aka feather stars. From there I started finding those Leptosalenias of which I only brought home the best ones. Lots of other good specimens of bivalves, gastropods, serpulids, etc started filling the bag and then I looked up and there it was, bucket list, holy grail of the GR, a CIDARID! Now I have several "pieces" from there but this one was obviously complete. It was still tucked into the marly layer and hadn't been fully washed out and broken up yet. As I removed it I found it was a bit squooshed, but otherwise intact. The species is Paracidaris? texanus (Whitney & Kellum). Smith & Rader(2009) placed it tentatively in Paracidaris, but it is probably a good ID. Spines and loose plates are common but articulated specimens are few and far between. That was it, I could have gone home right then and there, but I kept going. I was rewarded with a medium sized Tetragramma (semi rare) that will need lots of cleaning and a few more Leptosalenias. Eventually my alarm went off and it was time to head home. A great afternoon in Central Texas.

Hi All. I was unsure where to put this message so hopefully this place is okay. I teach 7th grade Life Science and we are soon starting our coverage of major animal types (arthropods, echinoderms, molluscs, chordtates, etc). I am hoping to put together a teaching collection that can be used each year as we do this. If there are members here who are willing to donate any/all types of durable specimens (harder for young teens to destroy) that could be used to teach students the key features of these phyla. If you are willing and able to share can you please PM me directly. I do appreciate it :-)

Hello dear fellows, Any ideas about this one from Fezouata Shale? It has 2,8 x 2,0 cm. A Brachiopod, a Hyolith, a Chrondrophore, a Clam??? Thanks in advance.

Hey guys. I am a new member and currently an 18-year-old freshman college student. I am currently going through basics but as a kid, I loved dinosaurs and prehistoric creatures. I recently have thought about changing my major from biology to paleontology. I am a fossil collector and hope to collect hundreds of examples of prehistoric life. As I said I'm a fossil collector but a novice at it. I know relatively what a given organism is but I want to know, if possible, the species. If they are completely unidentifiable, no worries. I might add that all of these fossils did not have locations of where they were found except the starfish which was found in Morocco. I'm making a log of all my fossils and want to know the genus of each individual one. I have linked a google drive folder with all the images of the ones I would like identified if possible. Feel free to message me with any questions or just to get to know me. I'm open to making friends with fellow lovers of life. Thanks. https://drive.google.com/drive/folders/1m0QB8pmy-snZYujwb6Fy06flKsRxQK3E

Fossil plate with echinoderms, making sure I found the correct tag.
nivek1969 posted a topic in Fossil ID
Hello. I have still been going through boxes of mostly cave mineral from a large estate sale purchase, mostly consisting of cave minerals. The tags that remain are not attached to the pieces and usually scattered among many boxes. This amazing plate I found recently and believe I finally found the label. I just need justification. I haven't found any other plates like this one. It's stunning in person!

The sample image here was collected directly from a Drag Line operator's windrow in a lime rock mine in Southern FL just outside of Naples around the Sable Palm area of the Big Cypress swamp of the Everglades in 1997. The specimen has been completely removed from the limestone petrol (lime rock low density ls) matrix. What is interesting is the general shape of the specimen and how this 5 million year old specimen differs from the present day specimen at the same general location. I am guessing the seas of which the archaic specimens existed in were more challenging to exist in general as the specimen appears more elongate than present day specimen possibly for navigational purpose in higher energy seas than say today. Consequently the respiratory flower on top seems to be larger than today's comparable specimen as a direct consequence in the different morphology.

Preparations for my 3rd Møns Klint Fossil Excavation
The Amateur Paleontologist posted a topic in Fossil Hunting Trips
Hey everyone - It's Christian. For the past few months, I was inactive on TFF as I had a lot of schoolwork.. But now, I've got a lot more time on my hands - which means that I can get back to all things fossil related This of course includes making preparations for my 3rd Møns Klint Fossil Excavation (MKFE - the fieldwork aspect of my Møns Klint Fossil Research Program). I'll be going for 2 weeks, in mid-August - I'm really excited! As I said in a post from a few months ago, the collection policy of this MKFE is essentially the same as last time's (cephalopod, crustacean, echinoderm and vertebrate material). This time, though, there'll be a bigger focus on articulated and/or associated material - eroded sea urchin spines and belemnite fragments are getting too numerous... On the first days of the field trip, I'll have to do quite a bit of prospecting for new sites to work at, because there's a chance that the landslide spoil heap from last year has most likely been washed away by the waves. I'm already having some ideas of particular projects for this field trip, which include a comprehensive collection of washout microfossils - to determine relative abundances of various faunal groups. Another project is the in-depth analysis of fossil material from different layers of chalk - which I hope will yield some zone fossils. Of course, I'm still hoping to find a lil' mosasaur tooth I'll also use this field trip as an opportunity to donate to the GeoCenter Møns Klint some of the fossils I found during the 2nd MKFE. I'll keep you guys posted! Stay tuned I'm so excited to getting back there! -Christian

All about my 2nd MKFE :)
The Amateur Paleontologist posted a topic in Partners in Paleontology - Member Contributions to Science
Hey everyone, I'm back from my second Møns Klint Fossil Excavation - it was absolutely fantastic! For the majority of 2 weeks, I was down at the chalk cliffs of Møn; and recovered quite a sizable quantity of (mostly echinoderm) good-quality fossil material. All of it is still safely stowed away in ice cream boxes and kitchen paper "field jackets", but I can not wait to getting down to preparing all those fossils. Unfortunately, I did not manage to rediscover the "Echinoderm Quarry", but I did on the other hand have the chance to work on some new, very fossiliferous sites. Along with extensive fieldwork, I also got the privilege of analysing the MK Thoracosaurine jaw fossil, and meeting the Director and the Fossil Guide of the GeoCenter Møns Klint. I'll give detailed and illustrated accounts of all that happened* during this successful field session in the next few days... Stay tuned *Except, of course, for my studies of the MK Thoracosaurine - that'll have to wait until after the paper has been published (IF it does end up being published)- 27 replies

So excited when this echinoderm I bought online arrived today! It is Camptostroma roddyi specimen from a private property at Lancaster County, Pennsylvania, from the Kinzer Formation. I dont know much about this enigmatic Cambrian echinoderm nor the formation it came from but I cant wait to add this to my small collection of echinoderms.
