  4. CNY Eurypterid?

    Hello! Recently I’ve had the chance to go fossil hunting for trilobites, in central New York. I’ve been to the hill site in Tully NY, behind the hotel. I was fortunate enough to find a fairly complete Greenops Trilobite, and a few smaller, less complete sections. I spilt open a section of rock, and saw what I thought was part of a large trilobite eye at first. I’m not too familiar with the types of fossils that can be found here, but the texture seemed similar to a small piece of the head of a eurypterid. I’ve never found a eurypterid before, and it’s been on my list for a while, so maybe it’s just me being hopeful. I’m not even sure if eurypterids can be found at the site I was at. I was hoping some one could help identify what I found, and hopefully learn more about what can be found here in CNY.
  5. Olenoides serratus

    Hi all, here is another of my recent models. It is a full-scale Olenoides serratus trilobite I did this summer. Like my Archaeopteryx skeleton, it was modelled in Blender and printed using an Anycubic Photon printer. I used clear resin and painted it with very thin layers, such that the model retains a realistic level of translucency, especially on the legs, gills and antennae. Attached are some photographs and a render of the parts. You can download the model files at thingiverse to print your own one. The length without antennae is about 7cm. Cheers, Thorsten
  6. Mid Devonian tiny trilo ID

    It looks to me like another eldredgeops, although the glabella looks slightly longer if I look hard enough. I find a lot of those out digging here (outside Winchester VA in the needmore formation) so that wasn’t what stood out so much as it’s size, and I do apologize for not including a ruler I just honestly don’t have one small enough. If it’s bigger than 5mm I’d be surprised. So I guess my main question is, would this have been a juvenile of the species? My understanding was that they gained segments as they age, but this guy looks exactly like the other much larger specimens like him that I find out there, seemingly the same number of segments.
  7. I have as organizing and pre-prepping samples today with the intention of having a very paleo preparation holiday. If you a familiar with the storied Millard County rock hound book, it mentions a site between the Amphitheater and The Pass that is good for red slate dendrites. With a bit of research and a lucky wrong turn, I found the site. If I had gone left I would have ended up at a dead end on a very high cliff... Anyway, here’s the dendrites: What I didn’t notice until tonight: A surprise pyggie!
  8. Need help for ID

    At the site near Slemmestad where I have found many graptolite, I came over this trilobite. It is a few cm long, a part of the thorax. Is it possible to identify which family it is? It maybe can help me to narrow the id of the formation's age there (Bødalen).
  9. Recent Trilobite Acquisitions.

    Hiya everyone just got these trilobites some extra help on them would be great including some prep tips thanks
  10. Can someone identify this trilobite?

    Hello all! I bought this bug like 20 years ago. If I remember correct, the vendor said it comes from Russia, Ural mountain range. Through a research, I found that there are a couple of paleozoic outrcrops in the area. I also checked trilobite species and looks like this one belongs to Redlichiida or Corynexochida order. These two orders have similar cephalon stracture (Cephalic doublure). The pygdium looks significant thinner than the rest of the body. I think I can count 10 ribs on the main body. Its total size is almost 5cm and the matrix is 7X5.5cm. I have increased the contrast using photoshop so as more details can be seen. Hope someone can tell me more!
  11. Found this guy today in the needmore formation near Winchester VA. It’s a very productive site but I’ve never found such a well preserved crazy spinous boy like this out there. I’m self taught on all of this and happy to hone my prep skills on standard fair like phacops Eldredgeops rana that I find out there all the time, but this guy is special and rare. At least for me. And delicate. Anyone here do professional fossil prep, and willing to give me a quote? PLEASE SEND ME A PM. The third pic is the mold that the pygidium came from and contains (presumably) the rest of the bug.
  12. Middle Devonian trilobite ID

    Found in the needmore formation just outside Winchester, VA puts him at mid Devonian. Only his pygidium visible but the rest of him (presumably) is still in the rock that contains the cast. The third photo here is the cast, taken at a slight sideways angle to get an idea of how it broke off from the rest of the rock. Hard to tell in the photos but the segments have alternating gold coloration, along with small spine nubs on the tops of the colored segments. I know it’s hard to determine from just his butt. Figure the order is Odontopleurida, closest match I could find was acidaspis calicera, but I couldn’t find a lot of good examples. Another thing, (and I know that this technically goes under the fossil prep board but, you know, while I have your attention) any tips on how to most carefully prep out the rest of him? It’s a fairly fragile shale material and he’s one of the trilos that preserves in a way that almost makes him seem made of the same material as the matrix, so extra delicate.
  13. Unknown Utah Trilobite

    This trilobite pygidium was found in a talus slope at base of Fossil Mountain in Western Utah. As you can see it is quite weathered. I found it about 25 years ago when my mom and I went back country driving in my Ford Tempo lol. That car went into a number of not car friendly areas haha. From what I know of area geology I believe it would be Ordovician in age
  14. Is this trilobite genuine? Any idea which species it is?
  15. Found this trilobite this afternoon between Capon Bridge and Wardensville. The formation is supposed to be Oriskany Sandstone, but it looked like siltstone not sandstone. Any help on identification? I haven't seen any with these spines in this area. Thanks! Matt
  16. Mystery hypostome in need of ID

    Hello everyone! So I was cleaning off a rock today and on it I found this tiny hypostome. I was wondering if anybody has an idea of what species this may have come from. This rock came from a site in North-Central NY that exposes the Ordovician Trenton Group. Thanks for looking!
  17. Top Trilo’s drawings

    Decided I would make a thread with my drawings, recently I decided to draw trilobites that are not necessarily proportional and I didn’t spend too much time on these just wanted them to be life size and recognizable, so far I have 19, I took ideas from @Kane trilobite drawings and @rew trilobite collection. I will add to this thread as I draw more fossils not only trilobites. You may not be able to read the labels partly from camera quality and mostly from my handwriting.
  18. Hiya everyone I just recently purchased this trilobite ain’t arrived yet some help would be great
  19. Impromptu Trip?

    Good afternoon, fossil friends! This post is a bit of a long shot, but I figured I’d rather ask than not! This may be the incorrect thread to PLAN trips, so if it is, please let me know and I’ll delete it! I certainly intend to share some stories from past trips, but I’ve found myself with free time Wednesday in the first half of the day and I’d love to go on an adventure fossil hunting with someone who is also available, should anyone be up for that! I’m also down to plan future trips for other dates! I live in Denton county and I’m more than willing to travel a couple hours for a productive site! I myself have only explored the well-known north Texas sites such as Mineral Wells, Post Oak Creek, and Lake Texoma. If anybody would like to go there, NSR, or any other places they know of, it’d be really cool to explore with another fossil fanatic. My girlfriend is a great partner, but I always feel bad boring her with my rocks! Plus, I haven’t gotten to explore or learn as much about the fossils of this region as I’d like. I was a part of Dallas Paleo for a while, but after moving out of my parents’ house I haven’t had the time to rejoin, but hope to in the future! For now, I’d like to take some of my free time to learn with other paleo nerds when I can. Please reply if you’re interested in meeting up sometime and heading out to find some ancient friends!
  20. Acanthopleurella

    While doing some trilobite research yesterday I came across this species of trilobite that didn’t get larger than 2 mm. I couldn’t find much information on it just that it was from the Ordovician and it’s the smallest trilobite. How do they know that it isn’t just a baby of another species?
  21. Hi everyone, an interesting fossil was found near Montague NY, most likely Glenerie Formation. Can this be the tail section of a Trilobite? Can anyone help with species ID if possible? Thanks to all that can help
  22. So, I tried out my new air scribes and media blaster today. Finally, time to play with real fossils for a change! I’m starting to enjoy all the half days I’m working due to the pandemic. First up a bug from Warren County, Ohio that I found as a Boy Scout over 30 years ago. For years thought this was a partial hidden in the matrix. Next is a brachiopod from Cass County, Nebraska It was fractured, but I reconstructed it.
  23. Hiya everyone thinking of purchasing this trilobite a help to say if it’s real would be great thanks
  24. Creek Bug

    Creek Bug Eldredgeops rana (Trilobite) Middle Devonian, Moscow formation New York I found this trilobite in Sept. 2019 and never shared it. Or did I Anyway, I was hiking in a stream going from one location to another and found this trilobite after my girlfriend stepped on it Not her fault really. She's busy looking out for spiders, webs to spiders, and giant web wrapping people up spiders. I saw the telltale black of the trilobites exo and knew what it was (note the algae staining on the matrix). This site isn't a place where we go to collect bugs. This is our fossil coral location with the occasional trilobite. The bugs at this site tend to be on the big side and this is no exception. Your average complete Eldredgeops from NY is around an inch. If this bug was outstretched, it would be 3.1" or 78.74mm. I cleaned it up a little but the matrix that is still on the trilobite is very hard. My main focus was, is there a pygidium or not, so that had to be dug out. I think the coolest thing about this specimen is that it survived millions of years and who knows how long as a waterworn cobble in a stream after some cute girl steps on it. Happy Collecting
  25. I had mentioned in prior posts that I had found a large trilobite (Isotelus apparently) and I just got it back from Malcolm so I wanted to post pics. I definitely wish there was less damage but the size is very impressive to me (about 8 1/2 inches long by 6 inches wide by about 1 inch high), so I really like this guy, especially since it is the first trilobite I found (earlier this year). The first pic is how it looked when I found it - it was covered in calcite and was barely recognizable (to me, anyway) as a trilobite. While part of me wishes it WASN'T covered in calcite, the fact that it was a large white-ish rock is what allowed me to find it, and I think the calcite actually protected it somewhat from the elements. The one side of the trilobite was completely encased in limestone, and Malcolm had to 'liberate it' - I can only attach three pics with this post but I will reply to my post and try to post more pics showing the prepping process. The second pic is the finished trilobite, with the ruler to show scale. The last pic has the 'little' 4 1/2" trilobite that I posted earlier in the foreground, to show the scale / size of the larger one. I am still working on my photographic skills, so sorry for the pic quality. This was found in Ordovician limestone in the Eganville, Ontario, Canada area.
