  1. First Greenops Prep

    I've recently attempted to start preparing the fossils I collected in upstate NY. With a lot of trial and error and some nicked specimens, I have started to get used to my primitive preparation set-up consisting of a nail, a sewing needle and a hammer. Here's a disarticulated greenops which was great practice: On a side note, I've noticed that freshly exposed shell is a nice black. Would anyone know how to get that back?

  7. I found this last Saturday in Brookfield, Madison County, New York. It’s pretty beat up but there are some features that can still be made out. I was wondering if it might be a bellacartwrightia rather than a greenops, which was my original thought. According to Karl A. Wilson’s Field Guide to the Devonian Fossils of New York, one way to tell the difference is the number of lenses in the eye in a vertical row. For greenops there is maximum of 6. This trilobite has 7 in some places. A picture of the eye, showing a vertical row of 7 lenses. A top view of the trilobite A side view A view of the pygidium Thanks for looking

  15. A truckload of trilobites

    As indicated in an earlier post, I found lots of trilobites while on the field trip with the NYPS on Saturday. At DSR I found lots of greenops cephalons and pygidiums and even a few 60 percenters. I also found a few Eldredgeops pygidiums and one well preserved cephalon at DSR. (And a couple random Dipleura pieces). At the second spot, which was brand new to the NYPS, I found tons of greenops. I found 30+ greenops. Mostly cephalons, pygidiums or thoracic segments. I managed to find 3 or 4 60% completes and 5 or 6 fully completes. No Eldredgeops at the second spot. The layer I was in must have been a Greenops layer.
  16. 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?
  17. Spring of 2020 We took advantage of the time off and the break in weather to hunt one of our favorite streams here in Western New York. This was just a spring scouting mission to see what was exposed after the ice and snow has melted. Some of the more interesting finds were a crinoid crown (very rare for this locality) possibly Logocrinus, Spinocyrtia granulosa open with both valves, Orthospirifer marcyi, a large Megastrophia concava cleaned by nature with epibionts, and 3 small nearly complete Greenops. We also found many small Favosites coral colonies, large Heliophyllum corals, and 8 different species of brachiopods. Happy Collecting!
  18. Hey everyone, Back again. Couldn’t resist lol. I figure I could offer up some positivity during these uncertain times. Unfortunately it’s getting pretty serious in New York State with C19 cases blowing up. Our family business is under some stresses and I had to make some difficult decisions today so this post is also a little therapy for me. I really love paleontology it allows my mind to wander away from the present! I got back out into the field again this past weekend on Saturday 3/14/20 and Sunday 3/15/20. This time of year I have very little to do other than go hiking/collecting on weekend. Summer activities aren’t here yet and collecting during those hot summer days can be rough. I’m itching to do more exploring for new locations in New York but I’m still drawn to the classics like Cole Hill. On Saturday 3/14/20 figured I’d check out the Middle Devonian Delphi Station Member of the Hamilton group in search of Dipleura. Still dreaming of an articulated specimen but I’m always happy with some nice cephalons. I took a couple field shots. They always look so nice fresh and wet haha. 2 nicer cephalons a nice inflated cephalon Some smaller cephalons Giving the pygidiums some love. One was big!! This looked interesting. Not sure what it is exactly. gastropods and bivalves!! A flattened cephalopod and I think that’s a branching bryozoan. Needs to be glued together. I didn’t get the complete specimen but I still enjoy the location. Does need some work to get into the bedrock. It’s getting tough to find places to work. Mother Nature helps out as time goes. up next is my Sunday 3/15/20 trip to DSR and I did really well!! Finally scored the Greenops I’ve been looking for! stay tuned
  19. Middle Devonian Trilobite

    This partial trilobite is from the Middle Devonian Thunder Bay Formation. Assuming it's either Pseudodechenella (P. reimanni) or Greenops (G. alpenensis) based on common taxa in faunal list. @piranha is there enough here to assign a genus? This has been eroded by wave action. Scale in mm.
  20. Iowa trip

    Just thought I'd share some finds from a club trip to the Devonian of Iowa last Sunday. It was a good trip. A nice clam. This Greenops disintegrated shortly after exposure. Crassiproetus sp. Before After. Enrolled Greenops sp. and Eldredgeops noorwoodensis Group shot
  21. This may seem like an obvious question but I’ve always wondered what specific structural differences are present between a Greenops and a Bellacartwrightia. Any help would be appreciated!
  22. Hello forum folks I went to DSR again yesterday 10/05/19 as I had another free day to go collecting. I may not being able to fossil hunt until the end of the month so I had to take advantage! I have been noticing the phyllocarids are coming from certain intervals lower in the quarry...could be nothing....could be somthing....before I assumed I figured I should test it. I knew the exact bedding plane my last Echinocaris came from so I planned on opening a shelf on that bedding plane. My thought was if I could find another phyllocarid on that bedding plane maybe it could mean something....clearly not enough data to make any final assumptions but heck who wouldn’t dig a bedding plane that has produced lol. I was still specifically upset I couldn’t find the missing piece to my phyllocarid from last trip so I did some scanning I initially. I knew it was a waste so I got to work on the bedding plane I desired. before I got started I moved a lot of over burden and got some nice slabs moving. Loving the wedge and sledge combo....so much easier on my body physically. anyway....I found this Echinocaris punctata about 30 minutes into clearing off the shelf. Same bedding plane!!! Only about 1-2 feet from the one I found last trip. Bingo!! I’m going to show a few close ups...this is a really interesting specimen. It appears to be A double carapace folded in half. You can see the margins of the other half and some spots actually fold over slightly that confirm this. It would be great to reveal the other side but I would have a very thin, flattened, fragil specimen. also.....I’m feeling like the boy who cried wolf here but are these mandibles I see on the top left part of the specimen (Seen below)? The margins aren’t as easy to see but it’s clear there are some type or serrations on each part. Here is a close up that does a decent job showing what I’m talking about. They are really non photogenic because of the rust on the shale between the mandibles. It messes with the margins visually. It was still really messy with debris/rubble when I found it so I wasn’t sure where the counterpart was under the rubble. Foolishly it’s on a slab I left behind and I’m going to try and rush out after work to grab it this week. I found this another foot away from the phyllocarid above. When I found this I immediately thought I had a rhinocaris phyllocarid but now I’m not so sure? Unless someone can say for sure. Just doesn’t look right. here is a close up.....it has some lines running across it that make me question what this is. So for now I’m not sure. I found this Rhinocaris sitting out in the open so I have no idea what layer it came from. I’m positive this is a Rhinocaris and it’s very different from the other unknown specimen I found. Here is a reference photo for people who are unsure what phyllocarids are. I really think this specimen is special like the one I found last trip. Also, I do find it interesting that this was on the same bedding plane and very close to the last Echinocaris phyllocarid. More field work will help tell the tale. More to come....my trilobite finds from DSR and I found a layer with all Eldredgeops!!! Really awesome. Stay tuned for part 2
  23. Penn Dixie Greenops

    Decided to tackle prepping this greenops today that I found at Penn Dixie a few weeks back. Part of the cephalon broke off in the negative, but the glue job worked OK. There is still some digging needed to expose the right cheek and pleural tips but they should (hopefully) be there. A fold along that side buried them deep in the matrix. Not a perfect bug but my best greenops found so far
  24. Quick trip to DSR

    Hey all, My sister had a friend in town and it was my turn to come up with an activity, so naturally I took them out fossil hunting! I picked DSR since there is a 100% guarantee that everyone who looks will find something. I spent most of the time there ripping up slabs for my sister and her friend to split down. Unfortunately a thunderstorm rolled in and we had to leave early, so there is a sizeable pile of fresh material waiting for whomever gets there next. The girls found some good stuff- brachs, crinoids, and a few dipleura & greenops cephalons. I had the lucky find of the day with a decently sized, albeit disarticulated, dipleura. I think the whole thing is there, but it will take some prep to find out for sure.
  25. Greenops from Hungry Hollow

    Hello again! I have one more ID request (for now ). I received this Greenops as a gift, but I think I deleted the email which stated the exact location/formation information - does anyone recognize the matrix that it's on? And is it G. widderensis or is it G. arkonensis? I have a document stating that these two species have been found at Hungry Hollow (near Arkona, Ontario, Canada; mid-Devonian in age) - are there two different Greenops species found at Hungry Hollow or only one (widderensis)? Thanks so much! Monica I'll tag @Kane and @middevonian for this one
