  1. Devonian ID please

    Any ideas what this could be? Is it a body part of another creature?
  2. More Devonian marines.

    So I went on another scouting mission today. New spot is looking like it will be amazing when I spend a day there. Only spent about an hour looking for fossils and found some interesting stuff. Also my first trilobite Cephalon!!! So stoked!! It has a chip on the front and I think the other eye could be in the matrix. The matrix is a lot harder than what I have found fossils in before, also seems like the fossils are much better preserved.
  3. Need help identifying a Devonian fossil.

    Also found this today. Anybody have an idea what this might be apart of? Thanks
  4. Placoderm material from New York?

    Found this nice slate blue piece in my recent trip to Western New York. What do you guys think? The piece isn’t very big, maybe half an inch - but it looks relatively thick, maybe a centimeter and a half?
  5. Devonian Bivalve? from Paulding

    I found this small "clam" last week at the Paulding Community Fossil Garden in Ohio. This specimen was found loose but likely came from the Silica Shale (Middle Devonian). It has a bivalve-y look, similar to the bivalve Mytilarca cordata which is known from here. However, the valves are not symmetric about the hinge line, although @Peat Burns suggested it could be a deformation. Any ideas are appreciated.
  6. Interesting assortment of fossils

    Last year while fossil hunting in a creek in Chenango Forks, New York I came across an interesting looking rock. The rock was primarily made up of gastropods with a few bivalves and brachiopods. It was a very crumbly, silty rock. I believe it is upper Devonian because I’ve only ever found upper Devonian rocks at that creek but I’ve been unable to find anything close to what I found in Karl A. Wilson’s Field Guide to the Devonian Fossils of New York
  7. Help with ID

    I picked this up at Salamonie State Park in Huntington County, IN. Someone suggested it might be an icno fossil? 4.5 cm x 1.5 cm. Thx!
  8. 360-Million-Year-Old Fossil Reveals Extinct Species of Fern-Like Plant SciNews, June 17, 2020 http://www.sci-news.com/paleontology/keraphyton-mawsoniae-08545.html the paper is; Champreux, A., Meyer-Berthaud, B., and Decombeix, A.-L., 2020, Keraphyton gen. nov., a new Late Devonian fern-like plant from Australia. PeerJ 8: e9321; doi: 10.7717/peerj.9321 https://peerj.com/articles/9321/ Yours, Paul H.
  9. Gastropod or something similar?

    Hey again, this is a very tiny ~.5cm shell that I found some time ago at the regular road cut at the Lost River exposure of the Mahantango Formation. I would guess it’s a Gastropod or something similar but if it could be narrowed down any further I would be elated. Thanks guys!
  10. ID-concretions?

    I found these in a creek near taughannock falls (Tompkins county, NY). Are these concretions? Do they possibly contain fossils inside? Thanks! 1. About 25-30 cm in diameter 2. About 40 cm in diameter, with an interesting protrusion on a side
  11. This weekend, I have to drive up to Michigan to finish moving out of my apartment since I graduated, so I thought I would hit up a couple spots along the way. I'll hopefully have plenty of pictures to post here, but my fossil-filled week began earlier than expected so I'll start with that. I couldn't sleep much yesterday and ended up getting up way too early, so I figured I would go check out a Middle Devonian spot (Milwaukee Formation) in SE Wisconsin. I think this spot is pretty well known, so I wasn't expecting to find much. The fauna is pretty similar to what I find in the Silica Shale in Ohio but not as well preserved, so I didn't collect that much as I will be hunting the Silica Shale this weekend. The location is quite scenic, and I spent a lot of my time hiking the trails. Along the trails are a few outcrops, including one that appeared to only have been recently exposed from a tree falling. Unfortunately, most were poorly fossiliferous at best. It seemed like a lot of fossils were concentrated in what are perhaps storm deposits, but these were in the middle of massive dolomite beds and were not worth the effort. I only found one outcrop that was really worth exploring. I think only surface collecting is allowed, not that I would want to bust out a sledge next to hikers and fishermen anyways. The best collecting seemed to be from the more fossiliferous Lindwurm member. The underlying Berthelet is much more thickly bedded and formed a natural ledge for the Lindwurm to collapse onto.
  12. Devonian Trilobite Pygidium

    Was looking through some small fossils that I’ve found, and I decided to take a closer look at this pygidium, and the smooth outline and small bumps lead me to believe that this may not be an Eldredgeops rana - what I usually find. It’s from the lost river, Mahantango formation. Thanks!
  13. Help ID - brachiopods

    Hi! A find from Devonian in central NY, Tompkins county (USA) again. Am I right with the following guesses? 1. Spiriferida (Mucrospirifer?) 2. Atrypa Thank you! I see often that a mold of a fossil is more clear and has more features than the corresponding cast. Is it usually the case or the feature if the rocks that I find? Is there a way to clean it to make the cast more visible or the features are lost already (e.g. #1 of the picture)?
  14. ID: another wood materials?

    Hi! This was found in a creek in Tompkins county, NY, USA (Devonian period). The shale rock contained these rusty/blackish marks. Is it just rock composition or fossils? Wood? Why is it that fish bones are a rarity in Devonian rocks of Central NY? thanks!
  15. It's been a long while since I've posted on here. I haven't been able to collect much lately, but I recently went out to some new haunts and came back with some pretty intriguing stuff I'll hopefully get to follow up on later. I'll start off with an interesting discovery I've had recently. The outcrop exposes rocks stretching from the upper(?) Brallier Formation to the middle(?) Foreknobs Formation. Although I tried searching in the past for brittle star trace fossils, I was mostly unsuccessful in this regard, and over time my interest in it shifted to the much more fossiliferous beds of the Foreknobs (formerly Chemung) Formation. A couple of years ago I posted about finding a fish bone in a boulder next to the outcrop, as well as pointing out I found some potential teeth. Going over my posts, that finding intrigued me so I dug deeper into the presence (or lack thereof) of fish remains in the upper Devonian strata of the region. What I came up with was an 1887 report of the Genesee Shale from New York, an upper Devonian formation roughly analogous to the Scherr (and possibly the lower Foreknobs by the sound of it, it's all rather ambiguous) in Maryland. The authors noted multiple occurrences of fish bones and isolated teeth in sandstone and "fine pebble conglomerate"...similar in description to the rocks of my own outcrop. Coupled with the knowledge of possible fish remains I found previously I decided it'd be worth it to give the outcrop a more thorough look over, this time concentrating instead on the conglomerate facies and ignoring the shale. What I discovered has so far been fairly interesting. As I stated previously the outcrop exposes parts of the Brallier and Foreknobs Formations, including several dozen feet of shale and siltstone in the Foreknobs grading into upper siltstone and sandstone beds closer to the axis of the syncline. Towards the top of the exposed section of the Foreknobs is a bed several inches thick of hard, pebbly conglomerate. After some searching the silty shale above and below the bed is mostly unfossiliferous, although local profusions in brachiopods, crinoids, and other creatures are present. The conglomerate, however, is densely fossiliferous to the point that it forms a veritable coquina in parts running for several feet along the exposure. Because the conglomerate is so hard (made up of quartzose pebbles and sand), and the underlying and overlying beds made of much softer shale and silty rock, the conglomerate is poorly exposed outside of the exposure wall, forming something of a canopy between it and the less resistant layers. It is covered in part by a dense layer of talus from the overlying beds, likewise obscuring part of the exposure. Luckily, however, a few boulders have eroded out from the cut and are free on the ground to examine, and a few loose pieces weathered from the boulders are present around those. In these rocks I have found one chunk of blueish-white fish bone(?), and several possible tooth fragments. I recently examined the outcrop wall looking for more bone/teeth still present in the outcrop, and discovered part of a fish tooth(?) exposed slightly above one of the boulders, and similar looking black enamel(?) specks that could be fish derivatives. They are distinguished from the quartz pebbles by their shiny black appearance, whereas the quartz is mostly lighter gray and translucent. Is this a possible bone bed in the Foreknobs Formation? More scouting is of course needed, but there's a strong possibility in my opinion that, at the minimum, this conglomerate layer is a decent source of fragmentary Devonian fish remains. Note the blueish tint to the fossil. This possible bone fragment was found in a boulder of quartzose, pebbly conglomerate in the middle-upper Foreknobs Formation (Famennian). Note the associated fauna of crinoid and brachiopod fragments. Crinoid stem fragments in particular are extremely common, comprising a large part of the conglomerate "pebbles." This boulder is derived from a layer above a Cyrtospirifer disjunctus bearing shale, indicating it's Chemung age.
  16. Found in Limestone Canyon

    Hello! I am wondering about a couple of fossils found in Yavapai County, Arizona, approximately 30km south of Ashfork, Arizona. I chose this canyon to explore because on another website I saw mention of Arthrodire plates having been found in a quarry here. That site listed those plates being found in the Devonian Martin Formation. Well, after some research I figured out that the quarry was associated with Drake Cement Plant, which is perched on the edge of a canyon called Limestone Canyon. So off to the canyon my son and I went. This canyon had several distinctly different limestone layers, but the deepest layer, exposed on the canyon floor, had a variety of these (most pics taken in the field). Most were in large slabs of rock, but we found a couple smaller pieces that we brought home. We are dissolving one in Muriatic Acid out of curiosity, and it is revealing a "ring" of fossilized material. Can anyone tell me what these are? My son is quite curious to know. Thank you for any help!
  17. 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
  18. 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?
  19. 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.

  20. 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:
  21. Double goniatite prep

    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:
  22. ID. Wood film?

    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.
  23. Unknown Marine Fossil from China

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