Paleozygopleura hamiltoniae Middle Devonian Hamilton Group Marcellus Formation? Delphi Falls, NY Collected 5/16/20 -
I'm thinking this might be a shard of bivalve shell, but I'm having a hard time placing it in the context of the possible taxa. Just wanted to post for ideas before I toss it in case it's something more notable. DSR, Windom Shale, Moscow Fm., Middle Devonian. Scale in mm.

These were collected on the TFF DSR trip last spring. I'm just now getting around to processing the fossils. I'll start with the bivalvia, because they were the primary reason I wanted to go to DSR (and to meet fellow forum members, of course!). My phone editor doesn't have italics, so the names on the photos are not italicized. Scale is in mm. If you see a specimen that is misidentified, please let me know. I have also included some for which I don't yet have a confident ID. Please chime in if you know them. Not sure on this one. Shaped like Prothyris but has radial striae. Not sure on this one... Paleoneilo. Which species? Not sure... Not sure... Not sure... Sharp angle at posterior end is throwing me off...

Any idea what species of trilobite this comes from? (Or correct me if I’m wrong in my assumption that it is a trilobite hypostome) Tully, NY

This one has me stumped. I think it is the body whorl of a gastropod (DSR, Middle Devonian, Hamilton Group, Moscow Fm., Windom Shale). It is smashed, but the full circumference of the whorl is present, which means the aperture has to be on the left (which is consistent with the direction of the growth lines) (see arrow). If that is the case, there should be a shallow furrow or ridge in the center of the whorl running parallel with the cords and perpendicular to the growth lines if it were something like Mourlonia or even a Bellarophontacea. I see no evidence of such, not even on the crimped / folded / smashed edges above and below. One would think that with such distinct surface detail that this one would be easy... Any thoughts? The fossil is about 46 mm in length. Scale in mm. @Jeffrey P, @Fossildude19, @Darktooth, @Kane Here is outer side of the shell. Here is the shell flipped over to show the other side of the whorl. I think the broken area on the right is where the body whorl continued to the second whorl (which is missing). Here is both views side by side: Here is where I believe the aperture is located (I have prepped to the edge of the shell, and the shell ends there).

These were collected at DSR during the TFF hunt last year. I am just getting around to processing the specimens. It's amazing that the diversity of bivalves I acquired was greater than the brachiopods! First, a picture of the site: Now the brachiopods (scale in mm):

This is a belated report from the Briggs TFF gathering last spring. Here are some photos of TFF'ers working the site: Here are my finds (not in phylogenetic order). Scale in mm throughout. I guess I'll start with one of my bucket listers, a large goniatite: Next, the trilobotes: And "those other arthropods": Now the gastropods: Other Mollusca: Crinoidea: Seedless vascular plant bits: I don't usually collect "hash plates" but such accumulations don't seem very common at these sites, so I picked up this nice one.

Hey again, this is a very tiny ~.5cm shell that I found some time ago at the regular road cut at the Lost River exposure of the Mahantango Formation. I would guess it’s a Gastropod or something similar but if it could be narrowed down any further I would be elated. Thanks guys!

Final Episode of Belated DSR Trip: Arthropods, Cephalopods, etc.
Peat Burns posted a topic in Fossil Hunting Trips
Here is the final installment of my trip report to DSR (last spring with TFF group meet). These are the rest of the specimens including Gastropoda, Cephalopoda, Hyolitha, Phyllocarida, Trilobita, Ectoprocta, Plantae, etc. Scale in mm. A Palaeozygopleura encrusted with the bryozoan Leptotrypella amplectens. A close-up of Leptotrypella amplectens I am not sure what this is. I am assuming gastropod, but unlike the Bellarophontids, this one doesn't seem to have the ridge or furrow down the center. It's also quite large. And the striations look different than any I can find that are typical of the site. @Jeffrey P, @Fossildude19?

Was looking through some small fossils that I’ve found, and I decided to take a closer look at this pygidium, and the smooth outline and small bumps lead me to believe that this may not be an Eldredgeops rana - what I usually find. It’s from the lost river, Mahantango formation. Thanks!

Found at the Lost River roadcut site, never found anything like it since. My initial assumption was that I’d found a marine plant, but the world of fossils is a broad and mysterious place, so I wanted to know what you guys think. Let me know if you need anymore info, and thanks!

Here with another fossil, and I’m pretty sure this time it’s actually a fossil Distinct striations on a smooth impression in the shale. Just half an inch longways and about .4 inches tall. Found at the regular Lost River cut, Middle Devonian age. Thanks guys!

This one is very strange guys. I was cleaning my fossils off and had noticed this strange shape - I thought it was dirt until it didn’t wash off. I found this in the Middle-Devonian aged Lost River roadcut near Wardensville. It’s got a thick outline that comes off the shale a little bit, but it shows up pretty bizarre on the camera. Let me know if I need to upload different images. Thanks everyone.

Found this while sorting matrix for micros. It's shaped like a brachiopod or bivalve shell, strongly concavo-convex. It has widely-spaced spines and very fine growth lines that follow the margin of the shell. I found two of them, and they are about 4 - 5 mm in diameter. My best guess is that they are "larval" shells of the gastropod Spiniplatyceras rarispina that have had the protoconch break off. I can't think of any brachiopods from that locality and time period that would have spines like that. It reminds me of the Permian Echinaurus, lol. Any thoughts? @Tidgy's Dad, @FossilDAWG

This looks similar to Mucrospirifer, especially the growth lines, but the interarea doesn't look right to me. I thought perhaps Brachyspirifer, but not sure if they exhibit growth lines like this. This is from the Middle Devonian Bell Shale. Scale in cm/mm. @Tidgy's Dad

I bought this from a box of unlabelled stuff that a dealer friend in the UK is gradually going through. Another friend IDd the coral as a Heliophyllum halli, perhaps from Hungry Hollow, which seems a good bet - I'm not very familiar with stuff from there though. Middle Devonian anyway. It was the epifauna that really interested me, especially this nice patch of the bryozoan Botryllopora socialis. (It also has other bryozoans, hederellids and cornulitids.) Scale in mm.

For the better part of a year I have been meaning to meet up with Tony @Peat Burns and do some fossil collecting. I have never met him before but we have PM’d on numerous occasions and he has helped me with ID help on a few items. Here is Tony- Well today worked out well for a couple of reasons, first we set the clocks back one hour which made leaving a 5 am for the 4 hour drive not to bad. Second, I crossed into the Eastern time zone so when I drove back, I felt 1 hour younger. Third reason was that I had a trunk full of various fossils that I wanted to give him. The forth reason is that it was sunny and 37 degrees- good fossiling weather. And the last reason was that my wife was coming home from a 3 day trip to Puerto Rico to check on her father who is not doing good and it also allowed me to drive to the Hinsdale Oasis on I-294 and wait until her plane lands at O’Hare Airport, rather than heading home and driving back which would add another 90 miles onto the 450 that I already drove today. I am typing this report at the Oasis, these are great for travelers on our toll roads, you can get gas, all types of food and rest. So after 4 hours and 230 miles of driving I made it to the Paulding County Community Fossil Garden In Cecil, Ohio to do about 3 hours of collecting in piles of Middle Devonian Silica Shale that the LaFarge Quarry, which is right next to this area, dumps here from time to time for collectors and school groups to search thru. Here are some pics of the area and some of my finds that I took pictures of in the field. Here is a pic of Tony looking at something cool find. I found various brachiopods, corals and trilo-bits. More finds in next post.

With fall just around the corner, I was able to get in a hunting trip with my friend Jeffrey P, to the wilds of upstate NY: Specifically, the Deep Springs Road Site, in Earlville. I met up with Jeff at our usual meet up place, and time, (6:00 am at a park and ride near Jeff - about an hour away from my home.) and loaded his gear into my vehicle. Off we went. We enjoyed some very nice scenery, once the morning fog lifted. Hills, streams, farms, and wildlife. We both saw a bald eagle flying by, and some turkeys, chickens, and a deer or two. After a stop for gas and some food in Roscoe, NY, we headed up to Earlville. It was, as usual, a good ride, punctuated with some great conversation, and some interesting music. We arrived at the site around 9:50 AM. The place looked like it had be worked quite a bit, with large areas of rubble from other people's digging. The weather cooperated nicely, - it was beautiful, with temps in the low 70's, and we enjoyed sun and some cool breezes. We got to work quickly, and finds came in drips and drabs. We both made some decent finds, (pics to follow.) Jeff getting ready to start the day. We hunted until about 5 pm. With a 4.5 hour drive ahead, (for me) we got on the road. A brief stop at everyone's favorite Scottish Restaurant, and a quick stop for gas, we finished the day out with more good conversation and music. Traffic was great until after I dropped Jeff off. I spent about 25 minutes in stop and go traffic on I-84 through Southbury. I got home at around 9:45 PM. Jeff is such a great guy to hunt with. Informative, supportive, knowledgeable, and often quite funny. I always enjoy hunting trips with him. Thanks again for another great trip, Jeff. Please feel free to add your finds here, Jeff. Hope you enjoyed the report and finds. Until next time, Kind regards,
