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.

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 figu

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 i

I noticed this in my garage recently, and was diverted from the task at hand by the need to blow the dust out of it and have a look. About all I know is that it's from Maine. Most of the rocks are mid Devonian or lower marine formations. There is a chance it's from up in the county (Aroostook) where I've collected terrestrial plants. Scale in mm

Just cleaning up a few finds from the Hungry Hollow Member (Mid-Devonian, Arkona, Ontario). I am awful at discerning between proetids based on certain fragments, so was hoping for an assist as to whether it is a Pseudodechenella or Crassiproetus. If memory serves, one has a bigger anterior cephalic brim. I can usually tell them apart if I have the pygidium (Crassiproetus has a more rounded, effaced one). I’m leaning more toward Pseudodechenella. Once the genus can be nailed down, I have a question about size ranges that I haven't come across in the literature. When measured around

Hi everyone, My sons found these in the back yard. I know they are some kind of clam, but not sure about specifics. They have pretty amazing details on them. Thanks in advance for any info.

Whelp, patience pays off. I got a new species for my Paulding list today: Basidechenella lucasensis Since this photo was taken, I've exposed all of the fossil. Most of it is there except the left librigena and left side of pygidium. I'm very happy with it, nonetheless. I'll post pics when the prep is complete. I won't post all of today's finds, but here are a couple other highlights (for me at least ): Not sure yet if this is Stropheodonta titan or Megastrophia concava, but this is a nice monster that will prep out nicely.

I found this Icriodus michiganus n sp conodont plus an ostracod on a hash plate , there was also a jaw with teeth on it on the same hash plate , it's from the Arkona formation,Hungry Hollow, South Pit, its mid Devonian. I collected it last year on a CCFMS club sanctioned field trip . -
Yesterday, Deb and I spent four hours at our usual spot in Arkona looking specifically in the Widder Fm for Greenops and other related goodies. It was one of those lovely days where it isn't too hot or too chilly to get some real hammer time. First up is the bench I'll be working. This is from the very beginning of the day, left and right shots. I've been working on this bench for the last four or so trips. Where all the tools are resting is just below the rich Tornoceras layer wherein are also found a higher probability of full Greenops. Much of the stuff on top of that is bits or
