Hey all! I thought I’d share some finds from this weekend. Me and my fossil protege @ChasingGhostsYT spent Sunday morning digging the Shawangunk formation in search of Eurypterids and the afternoon was spent digging the Lockatong formation. On the Eurypterid front tons of specimens were collected but a lot of them still need prep and cleaning. See attached photos below. The Lockatong was more difficult for me as i haven’t spent to much time collecting it, but I did manage to collect a track and some unimpressive fish scales. Below I’ll attach a picture of a Eurypterid or 2 the track and me digging the Eurypterids and me and Zach enjoying are chicken. I’ll have a lot to share after this weekend but for now thanks for looking!

This Eurypterid tail section is identified as Erieopterus microphthalmus. It is from the Chrysler Formation and is Devonian an age. I'm wondering if it is the proper identification for this tail segment.

Thought Id share some of my finds today from the Shawangunk formation! The beds I investigated today are stratigraphically the highest in the Shawangunk I've looked at for eurypterids. After looking through a dozen shale packets one bed caught my interest, after digging for about 5 minutes I realized I was in a new horizon. What differs from this horizon then the more basal Eurypterid horizons in the formation and this layer is the size of eurypterids, and the absence of Parahughmilleria maria. I spent only about an hour of digging before calling it a day and leaving. The specimens below are a few of many eurypterids I collected today. Top: disarticulated Erettopterus globiceps. Bottom: Hughmilleria shawangunk, before cleaning and then photographed under

I've found a few of what looks like remains from a trilobite or some other Ordovician arthropod at the Drakes formation in Louisville, Kentucky. Is that what these are?

Found in Southern Ontario (Late Ordovician), in a small creek bed with little erosion. I've never seen anything like it before, I think it may be the Mesosoma of a small eurypterid? Any feedback is welcome!

This is from the Ridgemont Quarry site in Fort Erie, Ontario. Eurypterids are the primary target there for most folks. It has the general form of a coprolite. Maybe ? Or is burrow fill more likely ?

Happy new year! I wanted to show some of the highlights of an unexpected discovery from December 31 last year. I was in my garage when I noticed a pail full of rocks so I decided to try my luck and see what I could find. While I expected to find a crinoid stem at best, about 75% of the rocks ended up having something or another in it! 38 rocks in all ended up being relocated to my room, some have just a few brachiopods or whatever, but some I only have the slightest idea what they are, so any suggestions are much appreciated. Unfortunately I have no idea where any of these came from so there's not much info I can give regarding location. Pic 1 represents some crinoid stems that have really nice depth, better than any others I've gotten. Pic 2 is a collection of what seems to be crinoids and brachiopods, but more cleaning will be needed. Pic 3 is where things get interesting. You can see these shapes which kinda resemble leaves or fish. One of them in the middle, even has a line going down the length of it that is pretty even, if that helps with ID. Pics 4-5 are this really small shape in a collection of crinoid stems that looks to me like some kind of graptolite, though I haven't yet found any genera that match it. Pics 6-7 have this straight ridge which may just be part of the rock, but at the some time looks a bit like a trace fossil of a worm's burrow or something. Pic 8 I originally thought was just another crinoid, but there are these marks in the middle which aren't like anything I've ever seen. My sister thinks they're eggs but I'm not quite convinced. Pics 9-14 has a lot of pictures because I found it hard to get a decent photo because of its size. The thing I'm mainly looking at is the long rectangular thing in the middle, which while I can't find much that resembles it, looks like it might be a eurypterid arm. Those were some of the key finds from this pail of rocks, I will of course update if I find anything else noteworthy. In the meantime, I'd appreciate any suggestions on what some of these could be!

Hi I am Wondering if anyone could give this fossil an ID the seller called it “Carboniferous Eurypterid” and it was from Knob Noster, Missouri they said it could be Adelophthalmus what do you guys think? The first picture is the fossil the second 2 are Adelophthalmus fossils found from the same location

Hello Everyone!! I recently spent a week with Allan Lang collecting eurypterids. Me and Allan have been good friends for a couple of years, he is kind enough to invite me up to dig with him! We found many things over the course of the week some of the highlights were a Proscorpius, a few complete specimens of Acutiramus, and many Eurypterus. Ill attach some photos below. We spent most of the time splitting massive chunks of waterlime from the Phelps member of the fiddlers green formation. It can be very dangerous at times due to the weight and size of the rock, but often many complete eurypterids can be found in them. The Proscorpius was the most exciting find for me, The quarry has produced quite a few this year which is unusual as they are incredibly rare. It was a super fun time, I always love hanging out with Allan and collecting eurypterids at the quarry.

I live in jersey near Philadelphia and I was hoping to find eurypterid fossils but the only stop I can find is Lang’s quarry which is over 5 hours away and cost a ton to hunt. I am wonder if anyone has found evidence of eurypterids in Pennsylvania , Maryland, or southern New York. If you have any pictures I would greatly appreciate it. Thanks, Noel.

Hey everyone, today I found a new locality!! This locality is in the famous Shawangunk formation and it produces rare eurypterids. I have found Shawangunk material at a few localities but its interesting to compare the abundance of fauna at different localities. This new locality (like the others) primarily produces Parahughmilleria, However, 2 odd specimens were also found. One really reminds me of the invalid species Dolichopterus otisius. It is likely Nanahugmilleria clarkei. The other specimen is much more odd to me it could be Hughmilleria shawangunk but it could also be Kiaeropterus otisius. Ether way these eurypterids are incredibly rare, the Shawangunk is a very hard formation to understand and eurypterids are very scarce. Even with all the challenges that come with these sites its still probably my favorite formation to collect. Photo 1. Hughmilleria shawangunk? Photo 2. Nanahugmilleria clarkei? Photo 3. Parahughmilleria maria Photo 4. Parahughmilleria maria Photo 5. Hardieopterus myops (could be mineralization)

An extremely rare eurypterid from the classic and closed Swatara Gap locality
Dean Ruocco posted a topic in Member Collections
Hello everyone! Today I acquired a specimen that is of a rarity that's nearly unparalleled. The specimen in question is the cuticle of a Eurypterid from the famous, classic, and closed Ordovician locality at Swatara Gap. I believe it is undescribed and I can tell its a eurypterid for sure by the scaling pattern on the cuticle. Eurypterids aren't unheard of at Swatara Gap but I have never seen a specimen or even known about a specimen other then the one I have. They are extremely rare and were probably over looked by collectors due to not knowing what they were. I acquired the eurypterid from a close friend, Kerry Matt. Kerry collected it over 40 years ago, after a talking to him about it (he knows I'm obsessed with these things lol!) we worked out a trade!! The eurypterid itself is most likely closely related to the genera Echinognathus and Megalograptus. This specimen is just breath taking and so exciting to me. It might be my favorite specimen in my collection!!!

Hi All, Here is a Eurypterid in a Pennsylvanian age siderite nodule from Indiana. I'm hoping someone can point me towards a family, maybe even genus, ID for the specimen. I know the images don't show many of the fine features but I'm hoping the overall shape is distinctive. Also, I'm just starting to wade through Eurypterid PDFs now but if anyone can recommend a good review manuscript for the group I'd be grateful. Thanks for your consideration. Here are the two halves of the nodule:

A few days ago I spent the day collecting eurypterids with my good buddy Allan Lang. Firstly id like to thank Allan for his kindness towards me and his mentorship toward me, I'm very grateful towards him hes helped me a substantial amount and its always good seeing him. Anyway we probably found about a dozen good eurypterids as well as some neat associated fauna. Ill attach some photos below of some specimens we found! Top to bottom. Dolichopterus jewetti Undet cuticle, Prehaps the weathered carapace of Buffalopterus or Acutiramus. (Allan was generous enough to give this to me and the Dolichopterus because he knows I love my odd eurypterids) Windrow of Eurypterus remipes. Undescribed Eurypterus Referred to as Eurypterus laculatus. Nice Complete Eurypterus remipes. Last picture is of me and Allan looking at a plate as I flip it up.

Found this literally right on the summit of Pen y fan in south wales in a scree pile. Have had a bit of a research and everywhere says fossils are very rare in this type of old red sandstone... does anybody have any ideas? Its about 3cmx3cm. Well aware it could just be a rock... Cheers!
