  1. I recently broke open a few slabs of rock I took home with me from Rickard Hill Road in Schoharie the last time I was there. The rock was very crystalline and hard to break and there weren’t a ton of fossils inside. I did manage to find a couple of trilo-bits that were very well preserved and very detailed. One of these bits I’m having a bit of trouble identifying. I’m almost certain it’s a trilobite pygidium but it looks like nothing I’ve ever seen before. The great preservation makes the details of the shell stand out. It is around 1cm long and wide.
  2. Partial trilobite pygidium

    From the album Lower Devonian Helderberg Group in Eastern NY

    Dalmanites pleuroptyx? Lower Devonian Helderberg Gr. Kalkberg Fm. Rickard Hill Road Schoharie, NY Collected 5/31/20
  3. Trilobite pygidium?

    Hi everyone, I am very new to fossil hunting and am hoping to find some trilobites. I am located in along Lake Huron in Ontario, Canada on a rock formation from the middle Devonian period. I broke open a rock on my second trip and found this but I am not positive what it is. I think it could be a fossilized pygidium from a trilobite but i am really just guessing. I have attached to photos of the fossil, if anybody could help me identify it or steer me in the right direction that would be greatly appreciated. Thanks.
  4. Today on a hunt I found on of the most unusual trilobite pygidiums I've ever seen from new york and cannot find anything out there to compare it to. Unfortunately the site is imported material from an unknown quarry upstate so all I do know is that its from the Devonian of New York based on other material found there, unfortunately I cannot attach a formation to this one. Also its also fragile and a very partial piece thats unpreped, I think its a ventral display. This maybe a head scratcher so maybe the trilobite experts here can help weigh in on what this can possibly be.
  5. Trilobite finds

    Good morning all! A couple successful days of collecting and to my amazement, two trilobite pygidiums!. My amateurish guess is Ameura missourensis? It was found in Kansas City in a Winterset limestone outcropping. When I looked closer, there is something I thought could be part of the cephalon or some other fossil in the second photo about 12:00? Not sure if I should pursue cleaning it (and don't know how )-thoughts appreciated! Bone
  6. Ridgeback pygidium

    Hi forum friends. Cleaning out the back of my pick-up, I noticed this pygidium. It looks a lot like the eldredgeops I commonly find here but has a distinctly high ridge along the centerline. Could be just a molt that was "pinched" upward by the sides ? or possibly something different Cheers .... and thanks,
  7. Trilobite ID help

    Do any of our trilobite experts know what this pygidium belongs to? It's Cambrian from Jingxi, Guangxi, China. It's incomplete measurements are 25 x 27mm. Help!
  8. So the new house and work have keep me way busier than I had expect. I finally got around to getting my prep room set up for the most part and got around to starting some prep. Here's what I started with. Then the progress of getting it there. I had an oopsie as my engraver kinda got away from me doing some damage. Finally I finished it off with a clear matte finish to help stabilize it and make it pop against the matrix.
  9. Racine formation pygidium

    I found this pygidium the other day in the Silurian Racine formation near Chicago, wondering if any trilobite specialists can help with species ID? I'm thinking Illaenus ioxus (is that current nomenclature?)but not sure. Thanks for any help.
  10. Cole Hill 7/5/19

    Hey fossil folks, I’ve been very busy lately moving into my new house and planning my wedding (8/9/19 is the big day) so I haven’t had a chance to report on a few recent trips. In the beginning of July I got some nice fossil hunting in...I went to Cole Hill Rd, DSR and Briggs rd but I’ll post the latter at another time if I get the chance. This is just a short and sweet trip report for Cole Hill Rd from Friday July 5th. I got out of work slightly early and made the quick 40 minute drive to the site. I hunted from about 545-8pm. I decided I would try to move some overburden and see if the rock was weathered below....I did a lot of work only to struggle moving the rock. Maybe the winter will loosen it up. I did end up finding a little spot with rock that was more “movable” and I had a little hot streak of parts and pieces. Nothing articulated but some nice cephalons and pygidiums. Heres some of the better Cephalons (sorry I missed the scale bar!!) plus a few body segments I found. The one at the bottom right is probably the best one but is covered by a brach. It looks like I could smack it with a hammer and pop it off but I’m going to wait for better equipment. I like the detail on this partial cephalon. Heres a line up of the better pygidiums I found. I really like the dipleura pygidiums because you can usually see faint evidence where the pygidium used to be more segmented as a juvenile. Kinda neat. Can’t ignore the associated fauna....some nice bivalves, a Gastropoda and a small cephalopod. That’s it for this trip. I still really want to find that “wow” specimen but I’ll have to pay my dues. It’s a very difficult outcrop to work, at least for me. Glad I found some nice partials, my last trip wasn’t as successful. I ended up going to DSR and Briggs rd the next day on July 6th and did decent. I had a really excellent find at Briggs rd I want to share so as I get the time I’ll try to post my fossil hunt from July 6th. Thanks for reading Al
  11. Trilo-bits

    I just went through my bag of trilobits from this summer. Most are identified. I am getting better with time!! Here are a few Small pygidiums, all between 1 and 2 cm. These small non descript tails are hard for me to identify. If there are ones that stand out, let me know, and why you think so! That way I will know for next summer's specimens. They are numbered. Thanks, Mike
  12. Trilobite Pygidium ID

    This morning I was going through a bucket if Black Cat Mountain matrix a friend gave to me. I found this nice negative of a large trilobite Pygidium. I wonder if some one might know the species. Thank you
  13. Devonian trilobite pygidium

    Found in Arkona, Ontario Age: Devonian Size: about 18 mm/0.75 inches Any ideas?
  14. Trilobite Pygidium

    I am finally getting most of my trilobite parts identified but still need some schooling on this pygidium: It was found in the Platteville/ Ordovician in SW Wisconsin. It is 4cm by 4.5 cm In addition, these two plates contain what I thought were just pieces of Isotelus, but the more I looked, the more I questioned my thoughts. Agree or change the ID? These plates are 12 inches by 6 inches. The asterisk's mark where the specimens are.
  15. Pseudodechenella?

    I was going through some containers from a few years back when I returned to collecting, and it had a bunch of pieces I had collected from my mixed fill location (lower to mid Devonian). I came across this little pygidium. The squares are 5 mm x 5 mm. Going through some of the literature to compare photo plates from Ludvigsen and Lesperance, as well as scanning the Proetids in Levi-Setti and Whittington, there just didn't seem to be a perfect match. The axis sits fairly high on this one, a little like Mannopyge halli, but unlike the M. halli does not have the terminal nodes. The axis "points" downward rather dramatically, and has some apparent incisions. There is a small but distinct margin on the pygidium that made me think one of the Dechenella types. I've tentatively labeled it Pseudodechenella although I am not comfortable with that identification for this one. The Pseudodechenella I usually find don't have this very pronounced axial feature, and usually have a kind of smoother shell on the pygidium. I may be overthinking this, but I put this one out there for our Devo bug experts. Much appreciated for any help on this one.
  16. Trilobite cephalon and pygidium

    Hi folks. At first glance, I labeled this cephalon an Eldredgeops but it doesn't compare well with other examples in the area behind the eye where the "dimples" are. There is also a sort of "horn" projecting from the upper rear portion of the eye. Just not certain about this one. Could just be deformation ? Then the nice size greenops pygidium. Wow, I'd love to find a complete one this size ! Thanks, Regards.
  17. Trilobite pygidium, Greenops ?

    Hi folks, This looks like a Greenops pygidium but has slightly different spikes than images searched for ref. This was in my typical dig area. Devonian, mahantango, eastern WV. It is quite fragile and was very difficult to expose without totally destroying it. Can you verify / determine the species ? Thanks ! Cheers.
  18. This is #8 and #9. Both were in the same split of shale. The larger one was barely visible, just 1/2 of the fwd center ridge. Took quite a bit of digging to expose it. I was pretty sure what it was, getting used to the little clues. Thanks again !
  19. Trilobite pygidium

    Found #6 last night. Only a small portion was exposed, I scratched the matrix away to expose the rest. I wish I had learned earlier what to look for more specifically. I am certain that I have overlooked more of what I am looking for than what I have found. Thanks again to all for you guidance, experience and willingness to contribute. Kindest regards.
