Recently I went to an abandoned quarry in Resteigne, Belgium. I've found some brachiopod fossils and corals. Sorry for the bad picture quality. Thanks to @Manticocerasman for suggesting the location. some brachiopods corals and other stuff

I pulled this out of the Mahantango Formation of Pennsylvania a couple weeks ago. It's middle Devonain. TI though as I pulled it out of the scree that it was more of the myriad corals, but looking at it more closely it is most certainly not (although there are a couple Rugosa tucked in there), the structure is all wrong. I was told by one sponge enthusiast that it is definitely sponge. some kind of sponge. I'm a taxonomist at heart, and it drives me nuts if I can't at least narrow something down to a family. The literature on porifera is woefully scant, especially on this coast. Looking at the steinkerns in the holes, it looks like a network of narrow tubes rather than the pores of one big sponge wall. Could this be Amphiporidae? Anyone have any good references?

I've been looking at these for sometime and am stumped as to what they may be. Found in Lansing NY. First up, photo's labeled #1 and #2 (hourglass shapes). I believe the matrix to be Tully Limestone. I have the scale written on one photo as 1.5 cm x 7 cm. They are of similar size. I wondered if they could be orthocone or crinoid but am unable to find any information or photos to compare them to as they are weathered. Both have the same somewhat zig zagging cross hatching patterns. Lastly, (#3) Believed to also be in Tully Limestone. I found what appears to be some type of a shell (2 cm x 3 cm) but it's shape doesn't resemble any of the gastropods, brachiopods, or bivalves in my area and I can't see any hinge. It appears that the outer shell has worn off and I think I'm looking at the internal mold? I don't want to try and prep it to reveal what may be hiding without any clue as to what it is. Thank you in advance

Went on a little "Easter Egg Hunt" with my folks, found some excellent fossils. day was hot but I enjoyed it. I have provided my best ID, but please feel free to correct if you can identify it further! it helps with my labeling system for sure. this lizard was good luck right next to where my mom was standing i noticed this beauty sticking out of the rock further excavation revealed this possible horn coral? eldredgeops rana heads trilobite glabellar fold ( possibly Odontocephalus?) Dipleura rib impression (Very exciting to have found 3 species in one trip!) amonoid Cephalopod Agoniatites vaxunemi (note the preservation of the sutre lines). and here is a conularid i found as well Possible pelecypod? brachiopods and lastly a couple of crinoid buttons dug out of the rock

So I took my folks out to West VA to see the Lost river site, had a splendid time of it just picking through the shale, but I found some absolutely mysterious specimens that I could use some help in identifying. This one I had thought was a colonial organism, but it doesnt match the bryzoan or corals ive seen in the area This one I believe is a brachiopod of some sort, any idea the Genus? I picked up this rock and noticed that there was a glabella furrow of a trilobite species in it. I dont know what species it is, all I know is that its Not an Eldredgeops. lastly a gentleman said that this looked like a sand dollar, however I am not certain its not just a formation. oh and theres this thing, I think its the tippy tip of a cephalopod. but a crinoid stem is just as likely. let me know if theres anything to look out for.

On Tuesday this week, myself and some of my family spontaneously decided to get out and drive to some interesting places in New York state to enjoy the day. We visited some beautiful locations like these two waterfalls: On our journey, we ended up around Gilboa, which is the location where one of the earliest known fossil forests was discovered with amazing plant and animal life, some of these fossils are exhibited outside near the town hall. This, being one of the many locations I had wanted to visit for years, was an opportunity I could not pass up, so while driving through the town we stopped by to take a look at these amazing pieces of history and get a few pictures: These are just some of the fossils displayed there, I have also really wanted to get to fossil hunt for some of the plant remains from this formation in Schohaire creek nearby, but unfortunately due to the very spontaneous nature of all of this I was not ready with the locations I had noted down where we could have done so and I did not get to collect anything from there on that day. We did, however, still have a little bit of time before it would get dark and I made the suggestion that we go collect some fossils at another, familiar location as it isn't often that I get to be around these places. So that is what we did, setting out for a quick hunt in the lower Devonian Kalkberg formation at a site only around 30 minutes away. Overall we probably got to hunt for around an hour, but it was a surprisingly productive time. Last time I visited here, I wasn't able to find that many of certain organisms I was interested in like the beautiful Leptaena sp. but this time, we found an abundance of these fossils, along with many other nice specimens. Here are some of my favorite finds from the trip: A few of those Leptaena sp. I wanted to get This one was my favorite, not the most complete but quite large and has very nice surface detail. A small but detailed spiriferid with some nice bryozoa: The largest spiriferid I've found here, needs some prep but a very nice fossil still: This one was a big surprise for me, I kept it because of the nice spiriferid on there but upon getting home I noticed a shiny dark patch below, turns out it was a Linguliform brachiopod, something I had never seen from the formation before. It's not complete, I wish we had noticed while we were there and potentially found the other side, but this is still a find I am very excited about. This also made me wonder something, most brachiopods preserve with a matte, sometimes slightly shiny texture to their shell, while all of the Linguliforms I have seen have a very glossy surface to them. Is this difference caused by differing shell composition? It is quite interesting and something that seems to occur throughout geological time, in many formations with varying preservation. @Tidgy's Dad maybe you know something about this? Some pretty nice orthids: This one was quite big, and appears pretty complete, I would like to get it prepped some day, I think it may turn out quite nice: Another strophomenid similar to Leptaena but with much shallower rippling along its surface, I was wondering if this may be another genus, looking in my field guide I see that Strophonella and Rystistrophia both also have concentric wrinkles, although I am not sure which if any of them this one may be: A coral? not really sure what this branching fossil is, but it seems quite interesting, not anything I've seen here before. A pair of nice solitary rugose corals: This one doesn't show up too well on camera but it's a pretty large platyceratid gastropod, I have a few from this location but this one has some very interesting wrinkles to the shell, quite different from all my other ones. This is another large fossil, I think it may be a gastropod also? it has a similar dark shell to most of the gastropods I've found here, plus it seems like it may be curving in a helical pattern out of the matrix slightly, but I may be wrong. And to finish, here are some nice hashplates I collected from the site: Thanks for looking!

Yesterday I was finally able to take another trip to DSR, ending my nearly 5 months of fossil cabin fever. While it wasn't as ground-breaking as my last trip, where my father and I found an 8 inch Dipleura and a complete Crinoid, this trip was still really fun. We checked out some different areas than usual and it definitely paid off. Starting off with some of the oddities: A gastropod I've never seen or heard of before today, Promatis (patulis?) This is the second largest bivalve I've found at DSR I didn't notice these brachiopods until after I cleaned the specimen off, I assume they were attached on the inside of the shell? This was pretty weird, my best guess is that it's a branch of sorts. The brachiopod ontop of it is really cool A pretty cool association between a Paleozygopleura (delphicola?) (hamiltoniae?) and a Greenops pygidium my dad found. The Paleozygopleura needed some glue which I will need to clean up. Onto the trilobites now: A really nice cephalon my dad found Dipleura tail, probably not related to the cephalon Some Dipluera segments and pygidium Our first complete Eldredgeops from DSR, my father spotted it in some loose shale while he was digging an area Headless Eldredgeops, probably would've been complete but the head is lost in another piece of shale at the site. My dad pointed this beautiful tail-less Eldredgeops out when he was clearing out some shale. I should've recorded myself pulling it out of the shale but it's not a big deal. The eyes on this guy are absolutely incredible! The only significant Greenops specimen we came across, unfortunately it is headless. I'll keep updating this thread while I go through more of the material we brought home. I fell asleep for 15 hours after the 4 hour drive home, so I didn't have much time today.

Hello everyone, I am new to the forum, and new to fossil hunting, and I was wondering about what the process of fossil hunting is supposed to look like. A couple days back, I went to fossil hunt at the Deep Springs Road side. There was a fossil that looked like club moss which went into the rock wall near the top of a ledge. Because I wanted the whole fossil intact, I attempted to excavate the fossil out of the wall by levering up the shale above the fossil using my rock hammer. I figured that this would be okay, but I was still left wondering whether excavation of fossils out from the rock wall was allowed or not. Is it frowned upon to excavate fossils from the rock formation? Should I only be splitting rocks that have already fallen from the wall, or is it fine to dig out of the formation? Here is a picture of the club moss looking fossil, if anyone more knowledgeable wants to identify it for me:

I collected this bivalve cast a couple years ago in the Silica Shale (Middle Devonian) of Michigan. I'm not super positive on an ID and was hoping someone here might have some thoughts. @Peat Burns @Misha @Tidgy's Dad? Thanks for any help.

Hi all! Please tell me this is more than a concretion! Edit to add location: Found in Lansing, NY. The matrix is a dark grey/black shale that breaks under it's own weight when I lift pieces and it breaks off into big chunks unlike thinner layered shale also in the area. I think I see crinoid stems and wonder if there are other fossils (Hallotheca acils ?) under a shallow layer of sediment making the cone shape appear to have rounded sides or is this something completely different (I think I've been finding nice molds of Hallotheca acils in close proximity to where I found this guy today). I hope to return tomorrow and find the other half to try and glean more information from the molded half. It was the only fossil in this piece of stone but I found two species of Rugosa and multiple species of Brachiopods in similar stones lying within a foot of it. It's delicate and I've wrapped it in wet paper towels and placed in a shallow dish with water. The entire item measures 2cm wide x 8 cm long. Thank you for your time

We recently moved to a new house, so It has been quite a busy few weeks since we last made a field trip. So I hadn’t much time to post the recent finds. On our last fieldtrip to the Belgian Late Devonian I made an exceptional find that I still wanted to share: I found a large piece of bone sticking out of a nodule. After the preparation and a some research I ‘suspected that the piece was a ADL (anterior dorsal lateral) armor plate from a Dunkleosteus. I’ve sent the pictures to a friend Palaeontologist specialised in Palaeozoic fish who confirmed the ID. Dunkleosteus sp. (ADL) Frasnian Chimay Belgium

Hi everyone, havent posted here in a very long time. I have been out fossicking a few months ago in a region of New South Wales, Australia in a devonian limestone dominated region. There are entire strata maade up of beds of Spirifer and Orthoceras and an array of corals, therefore its evident this used to be a shallow warm sea, of devonian age. There is this one fossil however, with images (attached to the post) that appears to be a ring almost however it has to layer. I have used a ruler for scale I'm unsure as to what this is and if it is even an animal. Any help would be greatly appreciated. Thanks for your time!

If it even is a horn coral? Not sure if it’s possible to tell from this. Found on Lake Erie in Erie Pa. Thank you.

Twenty years ago, I went on a field trip with my college geology class. We went to Mazourka Canyon in Owens Valley, Ca. The formation here is a grungy limestone, dated Silurian-Devonian, with abundant invertebrates that have often been tinted a brown-rust color. On this trip, I picked this up.. and 2 decades later, I *still* don’t know what it actually is, and nobody I have taken it to has been able to give me an ID.. I have always assumed some kind of coral but thats as much as I have ever gotten. attached are two medium-size photos, top and side views. I can get better photos if requested but I can’t find my phone for better clarity, dangit.

I collected these last weekend from the Millboro Shale (Devonian: Givetian) in Highland County, Virginia, USA. I cant seem to identify these and not familiar with Ammonoid taxobases, not sure where to start. I did go through House, M.R., 1962, Observations on the Ammonoid Succession of the North American Devonian. House does cover the Millboro Shale but only lists occurrences of Sobolewia virginiana, Tornoceras uniangulare, Maenioceras sp. I dont have access to the Treatise part K so any help IDing these would be amazing!

I recently have aquired a trilobite and do not quite know the identification. I later identified thinking that it is a Zlichovaspis rugosa trilobite from the lower devonian. I am still having hesistation though and would like someone else's opinion. It has nice detail in the eyes and head plate. You can really see it in the last photo. Thank you

Found near Cayuga Lake on the bank of a tributary. The raised spherical type shapes measure 3 - 4 mm in diameter and can be seen on several sides of the stone. I'm not sure what the matrix is but think it's a type of shale. There are so many types of shale in my area and I have yet to learn how to discern between them. This stone is very hard, dark grey (not quite black) and cannot be fragmented/chipped easily like others I find that can be crumbled in my bare hands. Could this be a coral? My field guide for this area doesn't show any corals that resemble this. I love this one!

Found this while splitting some black shale (Millbo ro Shale, Devonian) open, unsure if it is a trace or just a diagenetic feature.

Feather-like structure in one photograph and something like a chain coral. Thanks for guesses.
