So I find a lot of eldredgeops parts in this particular spot I’ve been digging for a few months (needmore formation outside Winchester VA). Particularly find a lot of cephalons. Some of them have been a bit warped/bent and I chalked it up to geologic forces doing the distorting. Came across this one the other day though that has a very focused dent in the glabella, like a piercing dent. I can’t for the life of me find the mold I split it from (it’s somewhere!) but it also has the corresponding dent, so I know it’s not damage done by me. Is there any way to know if the dent was pre fossilization/sign of predation? With it being so focused it didn’t feel the same as other specimen I’ve seen bent around the form of a natural split in the shale. Size is 1.5cm

Taking a break from my many projects to do a bit of planning/research for my 2021 Utah excursion, putting together my "preop brief" Kept stumbling on references to Bathyocos housensis. Its a "new" genus and the species description only has very nice stereo images of the cranidium. Looks like all the paratype specimens are also just glabella-centric cranidia as per SUNDBERG, F.A. 1994. Corynexochida and Ptychopariida (Trilobita, Arthropoda) of the Ehmaniella Biozone (Middle Cambrian), Utah and Nevada. Contributions in Science from the Natural History Everyone else seems to just regurgitate the same cut and paste mention from Jell, P.A. & Adrain, J.M. Available generic names for trilobites. which is just a mention of Sundberg 94. Was just curious if anyone has or had seen any images or reconstructions of this curious little bug. Looks like its a Drum, Wheeler, and Snake Range critter.

Working in the needmore formation outside of Winchester VA, mid Devonian gray shales where I find mostly trilobites, crinoid, brachiopods and some shelled cephalopods. These two little bits caught my eye. First, bifurcated spine (or looks like a spine? It’s preserved the way trilobite spines do in this formation). About 4 mm long. I’ve never noticed a species of trilobite out here that has bifurcated spines and now I’m curious. Second, cephalon next to a separate (I assume not associated?) pygidium. The pygidium I figure is a long shot on pinning down, but the cephalon looked interesting to me. Seems like something from the order odontopleurida? About 2 or 3mm wide

Hi all. I will be in central Arizona from Christmas to beginning of February and am wondering if anyone would be interested is a bit of fossil hunting? Would be willing to hit anywhere within a day's drive of Phoenix. Trilobites are my favorite but not afraid to dig for anything Only place I've done in Arizona is near Payson. My biggest limitation is vehicular, only car I have there is a mustang so getting off road is by foot. I am going to look up the current Latham shale (California) access for 1 spot. Thanks

Hello everyone! So a while ago I collected a couple of rocks while fishing up near Plattsburgh, NY. These rocks were from the Ordovician Trenton Group and contained a variety of organisms including inarticulate brachiopods and corals. More importantly though, were the variety of trilobites. In one of the rocks I found pieces of Isotelus, Cryptolithus, and Ceraurus. I was looking at a small piece of that rock yesterday when I noticed a strange little fossil. It was a tiny, spiny free cheek of a trilobite! It looks very similar to Meadowtownella trentonensis although it could be a different species. I do apologize if the pics aren’t great but the fossil is so small that I had to use my microscope to see any detail lol. Also, how do I get my images to be not turned sideways? Thanks for looking!

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.

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

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.

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!

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).

Hiya everyone just got these trilobites some extra help on them would be great including some prep tips thanks

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!

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.

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.

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

Is this trilobite genuine? Any idea which species it is?

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

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!
