Last week started normally, and ended with me driving from NYC to the Finger Lakes, the chauffeur for my fiance and her maid of honor for a half-week getaway (after 6 months of lockdown). With no plans of my own, I read a little about the area and saw mention of trilobites being found. My dad has a trilobite on the mantle when I was growing up, so I read further and saw many were found in a stream bed near where we were staying, and all of a sudden I was making plans to go fossil hunting. Luckily I found this forum and other resources in my quick search and learned the stream in question is on private property. I identified a number of public that looked similar/nearby on google maps terrain, and decided to look there. I made a few outings myself while they did their thing, and we all made a few stops along our drive and looked together a couple times. It was my first time, and it started slow. At one road stop my fiance found what might have been coral? Then I found a worm-looking thing at a roadside waterfall, but it cracked when i picked it up again. It was when I/we went to Clark Gully and Bare Hill Unique Area near Lake Canandaigua, and Kashong Creek near Lake Seneca that we really found some neat things (which I'll start posting below). I know very little about fossils but have ordered a book and started reading through this forum and other resources to learn more about what I found. I know the area is known for Devonian fossils, so I'm working from the assumption that these are from around then. In the meantime, I've given them all a gentle cleaning; I tried scrubbing gently with both dish soap and vinegar, the former seems to work better, but I'm trying to be as careful as possible to not damage anything until I know what I am doing. These first three fossils we found at Kashong in the stream bed. We found lots of amalgamations of shell imprints/other things, but these 3 really stood out. The first one you can really see the difference from before and after cleaning, in terms of the detail. Im afraid to do much more, and am open to any suggestions as I post some more! (Before cleaning) (After cleaning) Front view, before cleaning (Before cleaning) (After very, very gentle cleaning) (After cleaning) Thanks to this forum for helping me quickly brush up on the basics and find these guys, it was really fun!

Hi, my daughter is fossil obsessed and we are heading out to regional NSW for a trip and would love to do some fossil fossicking along the way. We are going to Canowindra, Parkes, Bourke, Broken Hill, and Griffith. If you have any suggestions as to places we could fossick that would be wonderful! thanks

I found this very compressed gastropod over the summer at the dump piles in Paulding, OH (Silica Shale, Devonian). I don't recognize it. Any thoughts? @Peat Burns @minnbuckeye

Hi, was on a road trip a few weeks ago for work and stopped at a spot where rocks had been excavated along the road. These rocks where full of partial leaf imprints and stems, alongside Trilobites and bivalves. The first pic is of a few partials I found, second pic has the fossil in question and a stem or leaf of sorts. I am not sure of the age as I'm still trying to piece together how there are leaves with the devonian fossilsI'm guessing that the the rocks are from different layers, the fauna bieng middle to late devonian while the Flora is permian in age. Anyway, will not be getting a chance to go out there anytime soon again. What do you think the spherical fossil could be? Thanks

Fossil hunting trip to Couvin (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Today I went on another fossil hunting trip with the fossil club the BVP. https://www.paleontica.org/sites/fossil_site.php?plaats=3&language=en We visited the "La Couvinoise" quarry in Couvin, Belgium. The rocks in this quarry are part of the Hanonet Formation which lies at the boundry of the Eifelian & Givetian. But the layers we searched in today where all Givetian in age (387,7 - 382,7 mya), I mainly searched in the Crinoïd & Brachiopod layer. Although I have to admit that we probably visited the quarry at a bad moment, as the yield was quite poor in the quarry this time according to members who've been there before. Which was quite obvious as I think we only found our first fossil rich rocks after 50 minutes of searching and even then the first hour of finds where few and poor in quality. But after a while of searching I found some good and rich blocks and managed to get some decent Crinoïd stems, Brachiopods and some rugose coral pieces. But the best 3 finds we did during the last 30 minutes of being in the quarry. The 1st one was the only Trilobite I found during the hunt! Trilos are very rare from this quarry and I believe only 1 other member found one before me on this trip. I found a pygidium which is still partially enbedded in rock. At first I wasn't sure whether I was a trilo or a brachiopod but after having a couple of other members checking it out, they all believed it to be trilobite. The excursion leader time was quite amazed by the find as this trilo came from the Crinoïd layer, which is a layer where he believed no trilobite had ever been found. The trilobites are usually found in another part and layer a bit further in the quarry. So yeah I am very pleased with that find! The 2nd best find, was one I didn't find myself but recieved from our Excursion leader Tom, which was a piece of very nice Stromatoporoidea which I wasn't lucky enough to find. The 3rd best find an perhaps my favorite was something that Tom told me to check out. He had discovered the remains of a cave that collapsed during some excavations in the quarry. You could clearly see the remains of dripping stones on the walls and luckily for us, some pieces of those dripping stones where also laying on the ground. So I managed to take a nice piece of them home with me They are encrusted with a layer of dried mud but I am sure they will look gorgeous once they are cleaned! The rings are already clearly visable in some areas. Here are some pictures from inside the quarry. This was the way to the newly excavated plateau which unfortunatly was a complete was of time as not a single fossil could be found in those rocks. After that we went to the other lower parts of the quarry where I mainly worked in a single piece of wall in the Crinoïd layer. I was lucky enough to find a few good fallen blocks and some good places in the wall with some decent Crinoïds and Brachiopods. One of the nice Crinoïds stems I found in the layer. And here is the piece of wall that has some of the dripping stones in it..jpg.ab575832af5fbab9d3391201e5f0e647.jpg)

Fossil hunting trip to Resteigne (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Yesterday my girlfriend & I went on a fossil hunting trip to an abandoned quarry in Resteigne in Belgium. https://www.paleontica.org/sites/fossil_site.php?plaats=10&language=en I am currently at home for some time due to mental health issues. I am currently dealing with despression and severe anxiety attacks all related to COVID-19, I am in a risk group and work in an essential store and the stress and way that people threat you finally became too much and I simply snapped. I finally decided to go see a doctor and a psychologist to help out of it all. Since besides going to work I hadn't left the house for the past 6 months and I really needed to get out to help me get rid of the stress and fear, so both the psychologist and doctor encouraged my to go on some fossilhunts as I needed to come out of the house and do some outdoor activities to help with my healing process. So yesterday I went on my first hunt to help me recover! The quarry we visited was an abandoned quarry in Resteigne and the rocks found there are Devonian in age. Most of the fossils found here are from the Eifelian (393.3 - 387.7 mya) and are part of the Jemelle formation. We arrived quite early at the quarry and spent almost 5 and a half hours searching for fossils here. Since we went on a normal week day, we were lucky enough the have the quarry all to our self! Since it was our first time in the quarry we didn't really find anything too spectacular, but I am very happy with the things we found and most important of all, we had a great and fun day! The surrounding environment was stunning and the weather was prefect, sunny but not too hot and not too cold! Ruguse coral in the rocks Only 15 minutes after we arrived we already found our first trilobite! Unfortunatly it was enbedded in a big boulder of very though rock at an impossible angle to remove. We did try to remove it, but when we noticed it would be near impossible and removing it would probably destroy the trilo we eventually decided to leave it. There where multiple other fossils in the same boulder, among them these nice Brachiopods.jpg.a1bc468431b9b60508a701a70f5cb055.jpg)

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?

A juvenile lungfish (11cm) from the famous Miguasha fossil site, now a UNESCO World Heritage Centre. Taxonomy from Fossilworks.org. Emended genus diagnosis from Cloutier 1996, p. 199: " Maximum depth of body one-sixth of its total length. First dorsal fin low, with maximum height from one-eighth to one-seventh its length, originating at the level of the fourth supraneural. First dorsal fin 16% of total length without ossified radials; second dorsal fin 30% of total length, and higher than first dorsal fin, itsmaximum height amounting to two-thirds of maximum body depth. Traquair (1893) erected the genus Scaumenacia based on the presence of a "double dorsal fin"; however, the presence of two dorsal fins is plesio- morphic and therefore non-distinctive for the genus. Hussakof (1912, p. 136) provided a series of distinctive features for Scaumenacia, some of which are used in the amended diagnosis." Diagnosis for the spcies is identical. Line drawing from Cloutier 1996, p. 207: Identified by oilshale. References: J. F. Whiteaves (1881) On some remarkable fossil fishes from the Devonian rocks of Scaumenac Bay, in the Province of Quebec. Journal of Natural History 8(44):159-162. O. P.

My son and I got our first trip looking for fossils in! We checked out a road cut exposing some Lower Devionian rocks and found a chunk of rock that looked like it came loose with the recent rains we had. There were a ton of Brachiopods in it. We didn't really dig around in the rocks or split anything. We really were just looking on the surface, but I want to learn more about actually finding fossils that are not just loose. We also checked out the rock formations in our backyard, which we only found 1 really tiny Brachiopod in it, despite a lot of searching what was visible on the surface! Lots to learn and we are looking forward to it! The formation in the photo is the one in our backyard. I am not sure how to search it yet thoughtfully though. I am also not sure of the geology of this area yet and we are searching for more information on it. Overall, we had a blast!

Sorry, the quarter was all I could find for a scale reference. My 8 year old spotted this in an area with lots of small Devonian fossils (crinoids, etc.). I thought this looked a bit like a portion of a eurypterid, but I am very inexperienced, and would not be surprised to find that I am waaaaaay off base. Any help with an ID would be very much appreciated! Thanks!

Really not sure what I have here, it definitely stands out from the surrounding matrix. I found this chunk at the Rockville Quarry site north of Harrisburg PA. There are some brachiopods in the surrounding matrix.

This “fossil?” Confuses me. Is it even a fossil? The shape throws me off makes me think its artificial but i found it in the middle of nowhere on rocky river shore. Geological?

Hey everyone, Just last week I took a camping trip to Watkins Glenn with my family. While there, I took advantage of the wonderful exposures prevalent in central NY and took to collect a plethora of Devonian age fossils. The first two days of the trip were solely dedicated took hiking and camping activities such as visiting the deep gorges present in the finger lakes area. You can see the steep walls of shale exposed along the gorge.

Microfossil slides and more tiny shark remains from the Devonian
fossilsonwheels posted a topic in Micro-paleontology
I finally got some microfossil slides and I got some additional Devonian matrix from New York. I decided to go back to the Genundewa Limestone matrix primarily because I failed to find shark related matrix from other locations that are of the same age. Each of the three searches in this matrix has produced different results which make it fun to search. This search was a lot of Phoebodus teeth and some were close to 75% complete. Easily the best Phoebodus teeth I’ve found in this formation yet. I found a fair amount of Omalodus teeth and some nice ones. I also found two incomplete mystery teeth again. Fewer denticles but a piece of fin spine. The shark remains are in the bottom slide in the picture. The top slide are awesome little fish remains including various Conodont elements, fish teeth, fish scales and what I think might be bits of Placoderm. These are not going in a display. They are just going to be study specimens for me. I think I can find or make microfossil slides that will hold the fossils in place better but these work now.

Another driveway find. Is this a sponge of some kind or possibly and bone from dorsal fin? Kind of looks in the shape of the ulna i cant find any reference on what an isolated one looks like. Can bones be calcified like this? i have no idea.

I recently visited a few formations around PA, The Montour preserve pit happened to be on the way and I stopped by, The location was quite picked over as @historianmichael told me, but we did manage to get some nice finds. I will post a trip report later but for now, I want to get some IDs for some of my finds from here and another location. First, is what I thought in the field was a brachiopod but upon closer inspection, I realized that this is probably my first pteriomorph mollusk which is very exciting for me, my question is: Which? I looked through Linsley and multiple look similar, I just don't have enough experience with these to really be able to tell.

Ahoi, I have been lucky to find some real fossils out in nature today! That is not as often the case for me as for some of you lucky rockhounds, I often have to resort to hunting online or building replicas. But this time I went out and found something. There is a famous devonian reef preserved in grauwacke some 50 kilometers from where I live. the Quarry itself is protected, but there are some piles of overburden rock in the vicinity. Here is a sample of what I found: To the right (1) I think is a badly preserved solitary rugose "horn"coral. To the left (5) a "ball" of favosites? The closest match I find for the big piece in the middle (3) is disphyllum quadrigeminum (No idea about species level, but it seems there are also solitary species of Disphyllum) The remaining two (2&4) may be one species, but I have no idea. I would appreciate clues on the ID as much as on where to find more information on identification of devonian corals in general. Its getting dark, so I will try to take better fotos tomorrow. Best Regards, J

After our succes last time to look for Devonian fishes, we went back to te same spot to look for more fish remains. Although the finds were less frequent we did get a couple of realy nice specimens. All the specimens are from the famennian deposits in Belgium. Natalie found a nice Holoptychius scale: And I found a large fragment of fish bone, possible Holoptychius or Tristichopterid. but the find that made my day was a big lungfish toothplate, after a litle bit of preppwork it reveald a stunning specimen: the cleaned up toothplate from the lungfish Dipterus cf. nelsoni :
