  1. Devonian Trilobite ID request.

    Photos were not taken by me so I cannot upload better ones. I was hoping someone could point me towards a species on this bug. Its 3 inches and 3/8th of an inch. Supposedly Devonian. Phacops?
  2. I am quite curious about whether you guys have bought or prepped trilobites in the "old style" (using more "primitive" tools) then went over them with an air scribe or other tool. I would love to see a before and after photo if that's possible.
  3. China Trilobite ID request #8

    Another VERY small trilobite.
  4. China Trilobite ID request #7

    This trilobite is only about 5mm in length.
  5. China Trilobite ID request #6

    Here is my number 6 unidentified trilobite. My photography skills are very limited, but if you need clearer photos let me know. Thanks in advance.
  6. China Trilobite ID request #5

    Good morning. Here is the fifth in my series of eight unidentified trilobites. Yes, the usual lack of additional information precludes me providing any ....:/
  7. Ordovician fossils in PA

    Hi everyone, I recently remembered the location of swatara Gap in Pennsylvania, I remember reading about it but the problem is that the site was covered up way before I was even in the United States, there is the swatara state park nearby but that has younger Devonian rocks of the mahantango. My question is are there any similar sites with Ordovician rocks anywhere in PA? I am especially interested in the Cryptolithus trilobites and if those can be found anywhere else around here as that would be a wonderful fossil to add to the collection and have the experience of uncovering. Thank you, Misha.
  8. China Trilobite ID request #4

    Again, I have nothing in my notes on this Trilobite except "China". Help.
  9. China Trilobite ID request #3

    I have nothing in my notes on these except "China". Help.
  10. Hi folks. Nothing spectacular, but wanted to share a first ... for me. Wet ground and high winds toppled many trees in my area last summer. I investigated an uprooted pine and noticed the shale was packed with fossils. I carried a couple of chunks home and cracked them open. The first one revealed something I haven't encountered before. A Dipleura Dekai and an Eldredge ops in the same chunk. I hope to do some more digging in the spring. Any corrections are welcomed. Thanks,
  11. Could this be a trilobite fossil

    Found this yesterday at a creek in brown spring missouri and wonder if it was from a trilobite possibly? And also was hoping to find out what this other piece of rock is because I find little ones often but never found one this big?
  12. First Trilobite From the Field

    I stopped by a prospective road cut today. Upper Mississippian (Salem Limestone). I didn't stay long so there is no trip report. Sorry... I promise a full report the next time I am there. I walked it for a few minutes and picked up a hand full of things. I mainly wanted to see if anything could be found and if it warranted spending more time there. I did split a couple of rocks to take a peek. To my amazement, on one of the splits, I found my first recognizable trilobite piece from out in the field! I have found a handful of trilo-bits in gravel drives, parking lots and the like, but never one when I was actually out hunting, so I am super excited! It's a little pygidium and I almost missed it. It is about 10mm long by 14mm wide. I don't know the area very well yet, but I have read that Griffithides bufo can be found in the Salem Limestone formation. I know it may be a long shot, but can any ID be made from this pygidium? The split wasn't the greatest, but I was able to save the positive and negative pieces.
  13. Middle Devonian Trilobite

    This partial trilobite is from the Middle Devonian Thunder Bay Formation. Assuming it's either Pseudodechenella (P. reimanni) or Greenops (G. alpenensis) based on common taxa in faunal list. @piranha is there enough here to assign a genus? This has been eroded by wave action. Scale in mm.
  14. General fossil ID

  15. Arctinurus?

    I think this could be Arctinurus occidentalis but not 100% sure...measures 20mm across. Any help appreciated. Sugar run @piranha
  16. Hey all! New to the forum and happy to finally have something to share. Went hunting in Montague, NJ two days ago on the first of the year and had some luck. I found directions to the site, "Mountaintop Rd. Fossil Beds" using instructions from the first entry on this list. Looks like it's all in the same town as Trilobite Mountain, which I unsuccessfully searched for early on in the day. Eventually I decided to try my hand at this second one before sunset hit. It's a shame that somebody seems to be using this property to hunt animals instead of fossils, but using some discretion you should be able to get in just fine. To my delight, my first fossil hunt yielded many interesting specimens. Shells and more than a few instances of Phalangocephalus dentatus. Wondering about how i might prep this one, which I found inside a larger hunk of rock utterly clogged with shells and trilobite fragments. Would it be useful to take a dremel to it? Also found this strange negative, wondering if anybody more experienced than myself has opinions on what could have left this impression. I hope to do many more fossil hunts in my lifetime. This was a perfect day for me, I can't wait to get back out and do it again. Cheers everybody!
  17. Hi everyone, I recently purchased this trilobite from a museum gift shop and unfortunately it came with no locality, formation or species information and I haven't been able to find anything similar online. Does anybody recognize it? The larger of the two is 18mm long and the matrix is very soft. Any info much appreciated!
  18. French trilobites ID needed!

    Hello and Happy New Year to all! Hope you all had a great time I saw these two interesting trilobite positive and negative from the Montagne Noire in France. I would be interesting in knowing their species and if they are rare/hold any value if possible (without giving numbers of course) Unfortunately 2 out of the 3 pictures are very poor quality. Hope you can still tell. Number one could be some kind of Psychopyge sp. ??? Curious to know your thoughts. Kind regards.
  19. Huntonia Eye Preparation

    I recently purchased another Huntonia oklahomae trilobite and am very pleased with it. However it does not have detailed eyes, I knew this when I purchased it but further inspection leads me to believe that the eyes are intact but have simply not been fully prepped. I am curious would it be possible to have the eyes professionally prepped to reveal the eye facets? If so what would be the risk of damaging the trilobite and approximately how much would it cost? Here is a picture, the trilobite does seem to be coated in some sort of clear coating, not sure if that makes a difference.
  20. Trilobite ID help

    Hello all, I bought this trilobite for my uncle for Christmas. It didn't come with any identification information, but I assume it is from Morocco. I was wondering if anyone could help me determine its name and age. Thanks for any help.
  21. Attached are photos of a Odontochile I took a chance on. It's nice size and while not cheap, for my purposes it was a good price. I was fairly certain it was legit when I originally posted it based off the high res photos, but when I got it I freaked myself out as I wasn't seeing the eye lenses, but they are there. Just a lesson in the dangers of high res photos I guess. Anyway, curious what ya'll think. Also curious if Odontochile is correct as I understand from searching there is some discussion about that. Thanks! Just wanted to add that it passes the bite test and I am unable to find any obvious seams in it with my loupe. I know it has some repairs but no restoration, but that was disclosed when speaking with the seller.
  22. This was my second time visiting this well-known Late Carboniferous, Kasimovian stage (305-7mya) spot on the NW edge of the Illinois basin. Here are some things I found. Some large brachiopods. After splitting some rocks, came across this nice tooth. I kept both halves for careful extraction/reassembly at home, which took at least a few hours. I don't know much about shark teeth and after researching, and from what I can glean from what scarce information is available, I think it's a Holocephalia subclass, Chimaera tooth. Possibly Cochliodus sp...? It measures 2cm. Correct me if I'm wrong, as I don't know much about teeth. Another cool thing I noticed is that it fluoresces a eerie green under ultraviolet light, however my cell phone camera interprets the UV light differently than my eye. I probably have to mess around with exposure settings or something. Whatever the case, it helps bring out details. Also,, found this genal spine of Ameura sp. with a tooth fragment(dark spot, lower right). I was crossing my fingers that at least the entire cephalon would be there ,but no dice... however, it also fluoresces glow-in-the-dark green which makes it stand out from the matrix easier to photograph. Ahh, to find a complete Ameura that fluoresces.. Thanks for reading.
  23. Hi guys! First things first, I've been following this forum (and this section inter alia) for a good year, I simply love the community, so I decided to join it and actively participate instead of being just an external viewer. I'm not a fossil expert, but I'm willing to learn and I'll do my best to improve. But I guess that since this is a fossil lovers community, it's fossils what you want to see. Well... I inherited from a granduncle of mine a LOT of minerals -geodes, crystals, nuggets etc- and fossils (I hope I can show you my collection over time), including ammonites -guess that guy litterally LOVED ammonites- of all shapes and sizes, dinosaur, shark and mammoth teeth, amber with insect inclusions and many many other things... including trilobites. The largest trilobite I got is this: it's a 27x17x4cm piece, not the best I've seen in my life but still pretty good IMO. No idea of where he got it, nor when, not even how much he paid for it. Still, I'm pretty sure it's a fake. But before officially confirming that my granduncle threw his money away with this, I'd like to ask you a second opinion. Thanks for your help, I'm sure he would really appreciate it (pretty sure atm he's resting in Paradise, surrounded by his beloved ammonites). (if you'd like to see more photos, just ask)
  24. I present this here large asaphus trilobite, besides being repaired how much if composited/fake is this trilobite?
  25. Burgess Shale Still Has Fossils

    I think this is a bait and switch article. It starts off by telling you about the Burgess shale then transitions into explaining why we are going extinct too. I didn't learn anything new from reading it though. Anyway there are pictures. Of trilobites. https://www.washingtonpost.com/outlook/2019/12/06/ghosts-future/?arc404=true
