Hi forum friends. Cleaning out the back of my pick-up, I noticed this pygidium. It looks a lot like the eldredgeops I commonly find here but has a distinctly high ridge along the centerline. Could be just a molt that was "pinched" upward by the sides ? or possibly something different Cheers .... and thanks,

Hello, I have been fossil hunting in Northeast Oklahoma near lake shores in an area where I have found bivalve, Bracheopod, and Crinoid fossils. I have been separating them into similar groups to identify them. May I get some help on this particular fossil type? Found in Northeast Oklahoma near the Lake Skiatook area. I am a newbie when it comes to fossil identification so I may be wrong on my tags.

Nassoviocrinus costatus (Goldring 1954) I posted recently about our latest fossil hunt in the Devonian of NY and showed you all the little crinoid we found. Whenever I find one of these ancient echinoderms that Im not familiar with, I show it to my friend George McIntosh of the RMSC. I sent some pics to George and he told me that it looks like Nassoviocrinus costatus. I never heard of that crinoid before so I had to look it up and learn a little. However, Index Fossils of NA was published in 1944 and this crinoid was described in 1954 and the internet shows very little about it (mostly publications by George ). I also couldn't find anything in the Treatise about it. If you have any information about this crinoid, I would appreciate it (especially photos). I have plans on getting this prepped and I will post the pics to this thread instead of starting another/separate post about it. I think its awesome that you can collect at the same locality for years and years yet still discover something new and exciting. Happy Collecting

I have some beautiful crinoid stem cross-section impressions from the Devonian Mahantango in PA (runs from NY to VA) and have been searching all morning to find a good reference book that won't cost me $100 just to open the cover and see if it's adequate to the task at hand. Winifred Goldring seems to have done the definitive works, but she didn't include any cross sections! Can anybody point me in the right direction?

A find at Tully NY the other day was bizarre compared with the usual stuff. Looks like a fish scale to my eye. Image was first hit on Google for images of “Devonian fish scales”. Example D and E look similar.

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!

Found on blackstone river NWT Canada. Not sure what formation it is but its either devonian or cretaceous nothing between. My best guess is Fort Simpson formation so late devonian.

I have acces to a more powerfull compressor since last week, so the past few days we have been quite bussy prepping lots of fossils. Those are some of my late devonian fossils I have prepped, this is my favorite one to start with, not only does it have 2 cinds of goniatites but I found it at adifferent location than the one I usualy prospect. Manticoseras sp and Tornoceras sp. Late Devonian ( Frasnian ) Nismes ( Belgium The next pictures ar all from my usual location near Chimay ( Belgium) (can you spot the intruder in the next few pictures? )

I was wondering if this is even a fossil or some kind of weird rock formation I found. It’s from NEPA in part of the catskill formation. Let me know what you guys think!! Basically all I’ve ever found there is trace fossils so I wasn’t sure if this is even anything. Thanks all!

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

Hi all! I pulled this fossil out of Red Hill, a Devonian site in central Pennsylvania. I thought it looks like it could possibly be part of a placoderm but I’d love to get some help with further identification. Thanks in advance!

Spent seven hours in the field today. Not much to show for it other than the usual, but I thought I'd show the process on how I extract a big rock. I am of the belief that there is no rock so immovable that my use of persistence and force cannot dislodge it. This one has been one of many that I have flagged for future extraction. First step was to clear off the debris to get a sense of just how big this one is. You can't make out the depth on this one yet. The next step was to exploit a crack to pop off one of the upper pieces.

I found these at an Oriskany Sandstone exposure in Blair County Pennsylvania that is normally overgrown. There was abundant crinoid & shell material around. There is no internal structure, and the larger specimen seems to show some faint longitudinal striations. ID suggestions appreciated ad. I was thinking Mud tube, filled burrow, cephalopod /shell cast, or plant bits. I couldn't find any similar pictures in my resources.

Hi, I am doing an emergency Fossiling trip to Western New York State. My entire family is very high risk for corona, and I am just leaving my college, where there were a few cases of it. Although I technically Do not need to quarantine, I am planning to spend at least a week alone before I go home to make sure I am asymptotic. That being said I will be spending the week hunting the shakes of New York State. I have been to deep springs and I just wanted to make sure that it is still viable. I am also possibly going to go to penn Dixie, but my main goal is to isolate and get some quality fossil hunting done. Any possible fossil hunting spots would be much appreciated in that area or the area of penn Dixie, if they are spots that are not densely populated

Hello awesome people! Im finally out of hibernation . I don’t mind fossil hunting in the winter...as long as the snow isn’t deep. It’s been deep lately lol. So the winter hunts have been non existent pretty much. We finally had a good enough thaw and a warm enough weekend to make collecting possible! I went fossil collecting and fossil prospecting this past Saturday and Sunday (March 7th and 8th 2020). It was great getting back out in the field. what a sight!! The snow didn’t bother me I was happy it was well above freezing for once. South central New York tends to get more snow and it hangs around longer it seems ha. Anyway....I did a little exploring and was able to find more Eldredgeops specimens in a few different spots in the upper quarry. It seems if you want to find Eldredgeops you have to go to the upper parts of the quarry. Personally, I’ve only found 1 Eldredgeops cephalon In the bottom 2-3 meters of the quarry. Doesn’t seems to be any specific layers but more of an increased occurrence in the sequence. It would be interesting to try and track the shift in fauna to see if it correlates to a shift in lithology/environment. It’s a very noticeable thing that goniatites occur in the upper levels of the quarry as well. If I remember correct DSR has been described as having a coarsening up sequence in the literature. I bet extra analysis would support that idea. It’s a fun place to collect and get into deep thought about “how the heck did these fossils get here like this?”. It would be fun to try and collect/catalog data from DSR. It’s been a looong while since I made a detailed stratigraphic section. I always label my fossils (location+date) but maybe I need to start including elevation in the quarry....hmmm Anyway.....onto the AWESOME finds from DSR ........plus 2 small finds from a prospecting spot. scale bar used in specimen photos are all centimeter scale

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

Trypaulites calpyso Trypaulites erinus Total: 40 New: 17 I'll be parking all my trilobite hunts for the year in this thread. With winter ending much sooner than we are accustomed to up here, it's about time to get back into the hammer-swing of things. This year is an ambitious one, no less on account of having spent some quality time with old literature, maps (new and old), to plot out a series of areas to prospect all across the province. A significant amount of fieldwork is planned as part of a broader research project. This past weekend was the season opener for me, with temperatures hitting about 4 Celsius on Saturday, and near 12 Celsius on the Sunday. By now, almost all the snow has burned off, with just a few shadier spots remaining. This is the view as I set out through the bush around sunrise. The ground was still frozen, which was fine as it made trekking over mud much easier.

Alternative names: Mitrocystites styloideus or Dalejocystis styloideus. Taxonomy from Mindat.org. Description (Südkamp 2017, p. 98): "The theca is roughly semicircular. It consists of two large thin plates on the oral surface, which nearly completely overlap the dorsal surface. The margin in the neighbourhood of the aulacophore is sometimes arcuate and bears medially the slender insertion of the aulacophore. Next to it, on the oral surface, short transverse riblets can be seen, which are directed to the aulacophore. The lateral margins of the dorsal surface bear a row of knots. The elongate aulacophore bears spines, which taper to the end. The anterior large ossicle (stylocone) has the appearance of a buttercup. At the other edge of the body a strong spine is attached, but is missing in most species." Name derivation: Stylos = pillar. Identified by oilshale. References: Dehm, R. 1934. Untersuchungen an Cystoideen des rheinischen Unterdevons. Sitzungsberichte der Mathematisch-Naturwissenschaftlichen Abteilung der Bayerischen Akademie der Wissenschaften zu München für 1934: 19-43.
