Could someone suggest a professor of Invertebrate paleontology, currently working, who has an expertise in New York State Devonian Era strata? I have a Phyllocarid specimen that may be of scientific value. Thank you- 1 reply

Hello, first time posting. This one is driving me nuts!
the_abyss_blinked posted a topic in Fossil ID
I have several others, but this one is driving me nuts. It's from Virginia. This is not in a Pennsylvanian area, but instead either Silurian (I'm doubtful of this), or Devonian, or Mississippian. The area has what looks like coal and pyrite as well. There ammonites, brachiopods and orthocones in the area. Any ideas?

Hello. I was wondering if you guys could assist me with identifying these corals. I've been trying to ID them myself using the William Davis "Kentucky fossil corals : a monograph of the fossil corals of the Silurian and Devonian rocks of Kentucky" from 1885 but there are no scale bars in the images which makes it difficult. These are each about a foot long. My friends and I found them while clearing brush and digging up their land in Clark County IN (near Ohio River and Louisville KY area). The geologic map of Indiana has them at ~Devonian, possibly Silurian. No idea on the strata but the rock was loose and limestone-y, and these were all found loose and pretty close to the surface. If it helps, we found others I've identified so far as Hexagonaria sp, Fenestella sp, Favosites turbinatus, misc bryozoan hash plates,and then a nice chunk of calcite. None of the fossils were small brachiopod or trilobite type but guessing they're there and have just plinko'd their way deeper down through the loose rock over the years. There are four fossils total, and I'll post a wide shot followed by a closeup of their side and a closeup of their end. Thanks in advance for any help you can provide and I'm happy to take additional photos as needed. I'd like to get better at corals and learn your processes for figuring them out. Thanks in advance! 1. Wide shot of first 3 fossils together; fossil 1 at left, fossil 2 at middle, and fossil 3 at right. 2. Fossil 1 side 3. Fossil 1 end 4. Fossil 2 side 5. Fossil 2 end 6.

Hey how's it going, long time lurker and recent member. Used to spend time here when I was younger and now that I'm graduated and back home in upstate NY, I'm on the hunt for bugs (and everything else). I've always been interested in paleontology, and just recently finished up a bachelors in evolutionary biology, with a focus on genetics. While my specific interests lie in ancient DNA and genetics, I've taken a few classes and been lucky enough to have had some experience in the field (in Kenya), and learned enough geology and paleontology to get me by. So far I have been hunting the exposures around Rochester/Buffalo/Geneseo and the Finger Lakes, but hoping to spend time elsewhere in the state as well. Looking forward to seeing what others find and how they do it! Here are a couple of finds from the last few weeks... I recently finished up my blast cabinet and prepping setup, now just waiting on a more reliable (non-Harbor Freight) air eraser and hopefully I will be able to clean up what I've found and post some of the best!

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.

This is a piece of fossil from Yunnan, China. It is from Devonian. The pieces measures 12x10cm. Any idea what it is? Thanks.

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?
