I was recently looking at one of my cephalopod fossils when I came upon this. The only explanation I can come up with is that it is a scolecodont, the jaws of polychaete worms, and these have been found in the Hamilton group before (Arabellites sp.) However, I've never seen pictures of scolecodonts in which the jaw doubles back on itself as it does here. I included an interpretive drawing to show what I am seeing. The size appears to be a little bigger than what my book predicted scolecodonts to be; I cannot give a precise measure because my microscope does not show this information. Am I simply looking at the top, like in the famous Websteroprion reconstruction?

Hello everyone, This weekend on Sunday my family and I made a short trip out to Central NY to do some fossil hunting. I was planning on doing this on my actual birthday which was on Monday but due to the weather we decided to do it earlier. As a result the trip ended up being more spontaneous, shorter than expected but still very enjoyable. The first stop was DSR, this was my second time at the quarry and although I didn't get as diverse of a selection of fossils this time (probably just being more picky), I got some nice specimens of a few new species as well as ones I already had. Here are some highlights: It was a great day for Spinocyrtia granulosa, lots of specimens, a number of complete ones. I especially like two of these This one is complete with very nice preservation and it's quite large. This one is the largest specimen I've seen. It's only one valve but in width from the wing tip to the end it measures right around 7cm, had it also had the other wing tip it would probably reach around 8cm. It also has some kind of borings around the commissure, I assume these occured after the animal died and the shell disarticulated, although I am not sure what kind of organism this comes from. I really love specimens like this as they tell such an interesting story of this long gone environment. Found a few nice Athyris spiriferoides, I really love these brachiopods and was excited about that. They were quite common this time but for some reason last trip I didn't collect a single one. A pretty nice, complete Mediospirifer auduculus This specimen I was very excited to find, I am not 100% sure but I think it might be Eoschuchertella arctostriata? Very beautiful in my opinion this is only an impression but I don't have any other specimens so I thought it was worth keeping. I believe this is Hyolithes striatus? Found a number of nice bivalves This slab has an Athyris and two bivalves, Pholadella radiata I believe Doesn't show up to well in the photo but this was a pretty nice Retispira leda I found I think this is Pleurodictyum americanum? Corals seem to be pretty uncommon here, and I don't have any Pleurodictyum in my collection so I was excited about this one. This last specimen for today left me confused, I found it exposed on the surface in pretty much the same condition it's in now. What confuses me is that the form of preservation looks very much like that seen in many lingulids, shiny black shell material. And the growth patterns also could fit that, but I've never seen any of this size or shape from DSR, so I was wondering if maybe it's some kind of bivalve, I'm really not sure with this one. I'll likely split this off into a different ID post with some other stuff later. I'm still sorting through and photographing the finds so I'll definitely update this topic more.

From the album: Nautiloid’s Trilobite Collection
This is a super rare Monodechenella trilobite from the Deep Springs Road site in Central New York. This specimen is the only one I have seen or heard of from DSR. I’m not sure whether this is M. macrocephala or an undescribed species. Collected August 19, 2022© Owen Yonkin 2022

Hello all! Today I met up with my good friends @Dean Ruocco and @KompsFossilsNMinerals to collect a couple of Hamilton Group sites in Central NY. The first site we went to was the famous Deep Springs Road site, and then we hit a second location for a little while afterwards. All around it was a good day of collecting, with everyone having success in the trilobite department.

Good evening folks. I am working on curating my middle Devonian collection using the field guide book by K.A. Wilson. It is very helpful and has saved me tons of time, highly recommend. I am posting below a few of the fossils that I could not quite figure out using the book and was hoping for help. A few of these may be unsolved repeats from past posts. I realize this may be a lot so very much appreciated in advance. 1. Locality Livingston County Two pieces of the same broken fossil 2. Deep Springs 3. Deep Springs 4. Deep Springs 5. Deep Springs 6. Erie Co. 7. Penn Dixie 8. Erie Co. 9. Penn Dixie
