I've often wondered as to the purpose of the tiny "claw" at the very tip of a eurypterid's swimming paddle. It's really very small and I can't imagine what it would be used for. It's not an anomaly as quite a few genera have them. Below are couple of pictures of one of my specimens, and just so you don't think me crazy and seeing things, there is also an illustration showing the feature. Any comments would be welcome. Tom

I have one simple question, How do we know eurypterid walking legs are legs? I find eurypterids to be one of the strangest Paleozoic creatures and while looking at some pictures of them I noticed how similar eurypterid walking legs and wobbegong mouths are. I have not seen yet just a single eurypterid walking leg fossilized alone. Any help would be appreciated thanks in advance

Hi all just bought this Silurian Eurypterid Balteurypterus head cephalon wasn’t overly expensive thought it looked cool and it’s from a trusted seller just wanted everyone’s opinion on it

Hi everyone - My wife and I were thinking about going eurypterid hunting this weekend or next if the weather cooperates. I was wondering if anyone is willing to share any public sites found around the Buffalo area (I know the Williamsville member is exposed in many places around Buffalo). Of course, we would not share this info anyone. Also, if anyone will be out at a site - we could even meet you there. I have a geology background but know very little about this area. Thanks! Pete

Sorry, the quarter was all I could find for a scale reference. My 8 year old spotted this in an area with lots of small Devonian fossils (crinoids, etc.). I thought this looked a bit like a portion of a eurypterid, but I am very inexperienced, and would not be surprised to find that I am waaaaaay off base. Any help with an ID would be very much appreciated! Thanks!

Hello all! As I’ve been taking a closer look at some of the rocks from my previous fossil hunt on August 22, I have been finding some pretty cool fossils that I overlooked at first. I am going to show some of the more interesting ones on this post. Enjoy! ~ Owen

Hi Forum members, Yesterday I went to a spot in Herkimer County in search of Eurypterids! This spot exposed the Fiddlers Green Formation of the Upper Silurian Bertie Group. I had never found a Eurypterid so I was excited to go, and I had heard this was a productive spot. I got there and the first rock I looked at had an exploded eurypterid on it! There were eurypterid bits and pieces all over the place. Eurypterids seemed to be much more abundant at this spot than I thought they would be! I only got to stay there for a half an hour but managed to track down a few nice finds. The rock at this locality is hard like concrete and is pretty much impossible to split (especially the freshly weathered out material). All of my finds came from surface collecting in the weathered out rocks. Thanks for looking! Owen

Hey how’s it going, just have two small things I’m curious about and figured someone would be able to put me on the right track. I’m not very familiar with this sliver of time and it’s a bit of a mystery to me. Both of these were found at different locations, but are Fiddler’s Green Upper Silurian “waterlime”. The first was found near some Eurypterid bits (on different plates) but it was surface collection effectively, and found in a large pile (little chance of recovering the rest of it and couldn’t find any at the time). The second is from the same strata but in a location a decent distance away. I did find that with some elbow grease, but found nothing else besides plenty of salt hoppers. Both localities are in western NY. The first measures out at ~6cm/2.25in and the second is a bit under 2cm/~0.5in. I can provide anything else that is needed (scale, better quality pictures, etc.) and would really appreciate any help I could be given. Even some reference material that I could use would be really helpful. Thanks! Here is the first: Here is the second: Edit: had to fix my pictures and formatting, accidentally uploaded too many pictures.

The museum I work for has been doing a series of short video segments called Fossil Fridays. I am working on one about Devonian marine animals. I can cover sharks, conodonts, acanthodian fish, coral, sponges, and trilos. I do not have any fossils of Eurypterids and would love to include them. I am hoping a TFF member might be willing to provide a short 20-30 second video clip of a sea scorpion. We would credit the fossil as yours and we only need location information in addition to the video. If you think you might be interested in helping us out, please send a PM.

Hey there! I know I know, I've been missing in action for the past few months. Work and Field work kept me busy. But I've now am taking the time to update my blog, and sharing some of my recent adventures. This one is not so much of a fossil hunting trip, but of discovery on fossil history in New Brunswick. A few weekends ago I went for a day trip to Saint John to meet up with my friend Matt at the New Brunswick Museum's Steinhammer Lab. He's currently doing a stint at the research facility and I couldn't resist, desperately wanting to tour this historic place. This building was the original New Brunswick Museum until it needed more space to accommodate a growing collection. In the 1990s, the exhibition displays found a new home downtown (Market Street area), but most of its collection (closed to the public) was kept at the original building on Douglas Avenue. This museum is considered Canada's oldest, housing collections dating back to its first proprietor, Abraham Gesner. The influence of the Steinhammer Club, comprised of geologists from the area and abroad, was pivotal in the history of Geology across the globe. They founded the Natural History Society of New Brunswick, and from there the contributions to science have been crucial to the advancement of several fields. I had also wanted to meet up again with Dr. Randall Miller, curator of the collections and museum, but he was currently out of town. I arrived at the old museum in one piece after dodging a hellish traffic and weird road designs. Beautiful city, crappy roads. Matt making sure Steve is hard at work I got to the museum and after talking to the wonderful staff, I met up with Matt and one other friend, Steve. Steve is an amazing fella and will keep you on your toes. They were in the middle of taking specimens collected in recent field work (a couple that I've participated in) and offered to lend a hand. We unloaded the material to the lab, and headed out for a bite to eat. After parting ways with Steve as he headed back to Fredericton, we proceeded in taking a tour of the Steinhammer Palaeontology Lab. I didn't take any pictures as Randy wasn't around and didn't want to take any just in case he didn't approve. Going through the collection, I've seen some incredible representations of various paleobiological and paleobotanical specimens, including many type specimens. Trilobites, which a cast of one of the biggest I've ever seen barely fit in the collection cabinet. Eurypterids, or sea scorpions, that could give you nightmares, were the size of your average family dog. Fish, bones, and even the remains of a wooly mammoth (Mastodon) graced the collection. This animal was collected from the Hillsborough area, near where I live. The tusks were incredible to behold. Walking through the halls, it was easy to get lost amidst the many artifacts laying around, beckoning, hungry for your attention. Even going to the washrooms you have to pass a wall of jars, each filled with animals living, and extinct. One doesn't linger too long in the bathroom let me tell ya. Also among the specimens at the lab were the many trackways that we collected, waiting to be analyzed and studied. Seeing specimens that you helped bring up in the light of day and residing in this place was quite a special feeling. As the day winded down, me and Matt chatted about the importance of keeping collections together, and the crucial role that these play. Every effort must be made to help save these as they help us understand our past and help dictate a future most rich. Our friend Margaret arrived near the end of my stay. As we said our goodbyes, I felt that it was imperative that I participate in the discovery and safekeeping of fossils, and to contribute in the advancement in the fields surrounding those of paleontology and biology. That is why I love geology, as it makes me have an intimate rapport with science, to which I love and am passionate to no end. To understand and comprehend, wonder even for what nature has left in our path, often hidden, for us to uncover and rediscover. Cheers! - Keenan Saint John River, view from behind the museum

Looking into going up to the Shawangunk formation near the Delaware River gap, looking for any fossils but would most like to find a eurypterid. My problem is I can’t find exactly where the fossiliferous parts are. I know it’s a long shot but has anyone hunted this formation before.

Today I stopped at a garage sale at an ESCONI members house, this is the same location of an earlier garage sale that I posted about a couple months ago. @stats Rich was there and he spotted this Eurypterid first and let me but it. I don’t know what I will do with it and I am not sure if $100 was a good deal, but I was happy with it. I believe this piece cane from Rochester, New York. If anyone has any info on it please let me know. I am really thinking about cutting it down to a smaller size and see if there is anything else in the excess matrix. i also picked up some miscellaneous flats of different prices. There were some larger pieces that were identified at coming from Saint Marie’s Cement Company, Bowmanville (Ontario, Canada) - Ordovician. I do not know if this is the correct ID, but here are some pics of some of the stuff after I split them. I got 4 large plates for $5.00. I got a flat of fossils that was identified as coming from the James Dick Cement Company (Brechin, Ontario, Canada). This flat contained various brachiopods, gastropods, etc., I paid $20.00 for the flat and separated out what I wanted and put them into a Plano tackle box. More in next post.

Found this artifact in Black's Beach, San Diego. Looks like a 6-ft scorpion. A Eurypterid maybe? I video and 3D scanned the find and sent it to The Nat and ROM (Toronto). Waiting for a response. Here are a few pictures. This ditch is likely to have been dug by the recent rains. Compare the size to my wrist watch: Closer look: Wavefront .obj file: Hit me up for high-res images, obj file, video, etc. Thanks!

Hey everyone! I finally had a day to go out and enjoy a Saturday fossil hunting with no time limit!! I decided to check 2 middle Devonian locations that have yielded nice dipleura specimens in the past. I’m still looking for “that one” specimen....eventually I’ll find one. I didn’t find the trilobite I tasked myself to find but I did find awesome stuff on Saturday . So here is a little trip report from Saturday September 28, 2019 plus some extra stuff I found earlier in the month. I’ll throw it in at the end. I got up really early so I could get to Cole Hill by sunrise. I had 2 sites in mind from the start. My new house is now only 30 minutes away from CHR which was a nice surprise! Early morning view I’ve had some tough outings at Cole Hill. This rock is so hard!!! I’ve tried clearing overburden just to get to more immovable rock. Anytime I get things moving I find something decent so that was the goal. Find rock that moves!! I ended up finding a spot way off the main outcrop and I got to work. I immediately found a plate with 5 cephalons!! It’s not being very photogenic so I took a picture after making them wet. the right shot shows 4 cephalons stacked in between the white scale bars....the left one shows the 5 hidden cephalon that Is under another cephalon. The bottom piece is just a cheek but could continue I’m not sure. Not very photogenic but rare to find an assemblage like that. I was able to find an area with more weathered rock and I found around a dozen cephalons!!! These are the better and bigger ones. I have a few nice juveniles but they are half covered in rock. I liked these 2 a lot. The left one is very 3D (also came in 10 pieces lol) and the right one has all the cephalon margins intact!! some nicer pygidiums I found. I found 7-10 total in various conditions. I found a lot of associated fauna as well!! The Gastropods came from mostly one bedding plane. The same spot I found the cephalon hash plate these were not far behind littered all over. I also found a bunch of bivalves! Way more than I usually do. I collected more on this trip than I have in the past. The rock kept moving and I kept finding!! After I worked the shelf back far enough I decided I wasn’t going to try and find a new spot. 4 hours of collecting and it was time to go to Deep Springs Rd. Even though I didn’t find exactly what I was after I found lots of amazing specimens compared to past trips . Kept my finder crossed that DSR would be as kind. DSR next post.....

Hi we've found these fossils in buffalo ny and based only on google searches we see resemblance with eurepterids as well as straight shelled nautiloids. Any help would be greatly appreciated. The photos shown are all different fossils I have them labeled a through c to make identification discussions easier. Thankyou in advance, we're learning!
