These are each less than a millimeter long and I have no guesses. Needmore formation outside of Winchester VA. Shale containing several trilobite species, brachiopods, crinoids, typical mid Devonian marine stuff. Seem vaguely porous but they’re tiiiiiny so it’s hard for me to say.

Four separate specimens, all partials. Found in the needmore formation (mid Devonian) near Winchester Virginia. First specimen- first 2 pictures- 1.6 cm: I’m guessing some sort of orthocone nautiloid but the evenly spaced squigly patterns threw me off (I find a lot of them but they don’t have that pattern). Also the fact that it bends a bit (second photo is taken at an angle to give an idea how the cast bends) although this could be from geologic forces. Second specimen- second two pictures- 3 mm: I honestly have no clue. Seemingly has spines? Seemingly thin bodied? Body seems like it has two lobes that might have some kind of segmentation? Third specimen- 5th photo- 4 mm at widest point: I would have assumed it was a partial of some kind of brachiopod but the pattern is checkered which I haven’t seen in a brachiopod out here. Also has those 3 main parallel ridge lines. Fourth specimen- 6th and 7th picture- 5mm: I know it looks like a crinoid stem cross section but they don’t look like that in this formation. I’ve found one other specimen that’s identical to this one but I can’t find it at the moment. Both are convex and don’t have any material continuing through the rock, it’s almost like a button. As always I’m greatly appreciative of the help I always find here. Y’all are alright.

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

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

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.

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.

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.

Split this slab of needmore shale I found near Winchester Virginia and found this. I am by absolutely no means an expert, but I’ve worked in this formation a lot and I’ve never seen anything shaped/sized quite like this. The way the rock split, it seems to have laterally bisected the specimen. The fossil itself is 3 dimensional and the shell of either side of whatever this is was left on both sides of the split, along with some interior matter. As to the shell, it LOOKS like it’s segmented into quarter inch segments, also has the impression of what LOOK like eyes but can’t be sure. As to the interior matter, the most striking of it is the white chalky material, located on only one side of the specimen. I’ve never seen rock of that consistency anywhere in this formation myself, so again, no clue. Lastly there’s the smaller fossils immediately surrounding the largest fossil. They look to me (at least a couple of them) to be trilobites that just got preserved next to whatever this is, but again...
