  2. 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 otis
  3. 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 eury

    Eurypterid In Siderite Nodule

    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:
  5. 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 a

    Fossil ID? Eurypterid?

    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!

    Bertie Problematic

    Here's an enigmatic specimen that has puzzled me. There are other specimens that have been found. One researchers opinion was it was a Telson that washed around and became "loosie goosey", Another's was its from Dolichopterus which also could make sense. Others have said its from some sort of Pyllocarid or a Acanthodian. I personally agree with the Telson theory but id love to hear your opinions!!
