Finally time to go back in the field after that long period of confinement . So this Saturday we went back to the Ardennes to prospect Frasnian ( Late Devonian ) deposits. Not a lot of finds, but it was good to be in the field again, and Natalie did find some nice quality fossils. Enjoy the pictures : A placoderm fragment: Bryozoa: not a fossil coral nodule with a few Tornoceras: same piece after a little work:

This weekend we finaly got out after those long months of lockdown. This time I am prepping a gephuroceratid that Natalie found. They are often found on top of the limestone banks, but this time she found one peeking out the center of the limestone bank. The position of the fossil didn’t make the prep any easier, since I had to grind away as much as possible of the matrix with a powertool without cutting in the fossil. Luckily I just missed a 2d goniatite hidden in the matrix with the grinder. After 4 to 5 hours of prepping with grinder, chisels, with air scribe and a finishing touch of color deepener for marble, this is the result: 2 Manticoceras sp. Late Devonian ( Frasnian ) Lompret ( Belgium ) As found: Step by step:

Hi! Found this rock on my today’s walk. It is similar to the one I found before and that one was IDed as carbonized wood film. Is this one also wood? Can anything else be learned from this piece? Thanks! Found near a creek, in Tompkins county, NY, USA. Devonian period. The black piece is about 5cm in length.

Several years ago I took a trip to Madison County to collect at the various Middle Devonian locales: Deep Springs Road, Cole Hill Road, Briggs Road. I am working back now through what I found and was hoping to get some help with an identification or confirming an identification.

Found this rock (upstate NY, Tompkins county). Main rock seems to be shale, but what are the black inclusions in it? The rock on the last picture is different. Is that print from an organism, or just a rock structure? Thanks!

Hi! Found this interesting rock on my walk today with a lot of remains. Sone of them I can try to ID (I see lots of crinoids), but there is also new staff. location: Tompkins county, NY, USA period: Devonian size:1-2 cm Rock compositions: shale with layers of remains-rich material Items of interest: On the last picture what are the comb-like structure and two things that remind me of sea acorn? Thank you!

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!

Hello again. Today I have what may be a conulariid from the Lost River. General consensus on my Instagram was that this was a conulariid, but I’m wondering if anyone here has anything else they might be able to tell me about this thing it’s exactly one inch across, and the small circle on it is a little Brachiopod I hope the pictures are good enough - let me know if i need to post something else. ‘Also for future reference, should I do individual IDs or do them all on one big thread? Thanks!

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.

Thought I’d make one of these posts on the chance that I end up spending a lot of time posting here. Hey there everyone - I’m Cameron. I’ve used this site for a long time but never made an account until a few months ago. I’m from central VA and travel to the Lost river near Wardensville just to find bits of Eldredgeops, and I’d love to talk fossils with anyone on here as nobody in my offline life is very interested in the topic. I hunt marine outcrops from the Mahantango and Carboniferous swamps in Pennsylvania, and I’m building up a fairly decent collection. Ive found many fossils that I don’t have a clue about, and learning anything about paleontology makes me squeal like a little girl, so I’ll definitely be posting in the ID section a lot! I’ve even found a conulariid in WV which people seem very excited about! I look forward to posting more here, hopefully I did this post correctly.

First post, long lurker! I found this fossil a while back at the well known Lost River outcrop on old Route 55 near Wardensville. It’s about an inch tall and across, and has an intricate, almost web-like pattern when you look close enough (my camera has a hard time picking it up!) I thought it may have been some kind of coral or bryozoan - but someone mentioned it may be a Hyneria scale or scale of some similar fashion, and that I should ask here. Any ideas guys? Thanks!

Last year while on a fishing trip in Ithaca, NY I found this as well as some brachiopods in a small outcrop of shale along a stream. I’m pretty sure it’s Devonian in age but I haven’t been able to identify the species.
-
So I found both of these specimens a while back and just assumed it was some sort of cephalopod, but I’m not sure what kind. They were both found in the same area in west Michigan. Any information on these would be really helpful, thank you!

Hi! Found today a rock containing what seems to me fossilized objects. Location: creek near Ithaca, Tompkins county, USA (Devonian period?) Size of the objects: 5-10 cm (didn’t have a ruler with me for more precise measurement) thank you! Wood or bones? can this be fish remains?

So, funny things happen. When my parents bought the house we were in we found this limestone plate of brachiopod imprints in the rock garden. Not only until 16 years later after I became interested in fossils, I realized our front rock section in the front of our house is the same limestone full of fossils. There a few a good pieces and one of them I opened up the layers and found a bunch of imprints. Almost all of them either look like brachiopod impressions or fossilized brachiopods...but there is this one I find here and there that intrigues me. No idea what it could be. So I also drew a sketch of it as its hard to make out. I do know that the rock is limestone and most likely Devonian.

Two Sites in Central New York in One Day 50 million Years Apart
Jeffrey P posted a topic in Fossil Hunting Trips
It was an all day outing on a perfect spring day in Central Upstate New York. Al Tahan and I visited a small private quarry where the Middle Devonian Oatkacreek Formation Mottville Member, part of the Marcellus Shale and the lower Hamilton Group is exposed. It's been about a year since I visited the site which I've been coming to for the past five years and it was Al's first visit. Erosion had broken down almost all of the pieces of shale which covered much of the site on previous visits. However a lot of fossils here, preserved in calcite are weathered free from the matrix and surface collecting can be very productive. This is by far the best site I've been to for the gastropod, Bembexia sulcomarginata. There were dozens strewn about the site. I couldn't resist picking up a few adding to my already extensive Bembexia collection. Brachiopods were also plentiful, especially the large spiriferid, Spinocyrtia granulosa (upper right). I couldn't help adding this inflated example to my large collection. Upper left is Mucrospirifer murcronatus, certainly one of the most abundant and distinctive Middle Devonian brachiopods in New York. Lower left is Protoleptostrophia perplana, a Strophomenid.

Hello everyone! I’m looking for any information on conulariids while showing the one I found! I found this specimen in west Michigan while fossil hunting recently. I used my microscope to get very zoomed in details of the ridges as this conulariid is very well preserved. The two very close up pictures are a 1000X while the last picture that isn’t as zoomed in is 50X, both are the same spot of the specimen. I know that these are thought to be some type of jellyfish/coral but that’s all I know of these fossils. Any more information would be really awesome, and I hope that you enjoy this find!

Hello fossil experts! I have a background in geosciences but know very little about fossils. I found the below fossils along the Rouge River near Detroit (Michigan). Doing some quick research, I think these are from the Mucrospirifer order, probably of the Thedfordensis species. Do you agree? (longest is about 1.5 inch / 4 cm) The thing I'm most puzzled about is from what strata they are from. The interweb tells me these Mucrospirifer here are mostly from the Middle Devonian (Antrim shale, Traverse Group), while the location where I found these (as well as all of the upstream terrain) has younger bedrock, from the early Carboniferous/Mississippian (Coldwater Shale). This Coldwater Shale is a pretty thick deposit so a river/glacier can not puncture it easily. I used the Bedrock Geology map from www.esrs.wmich.edu/mgs/webmgs/migis.html Thank you very much for your insight! Jazz
