  1. Unknown coral? Likely Devonian

    This one has had me stumped since 1985. Found it while I was supposed to be harvesting potatoes. Not sure of exact member as was kicked up by the plow. Collected October 1985 by yours truly. Erie County Pennsylvania Summit Township Upper Devonian - Chadakoin Formation (?) Found as is...red is from a wax marking crayon I didn’t realize I had in my pocket when I brought it to work today. Detail photos of conspecifics included.
  2. Mid Devonian cephalopods...or gastropods?

    So I found this fossil skull... Kidding! Anyway, back digging in the needmore formation outside Winchester VA and I’ve started finding a lot (like in one small part of the exposure, a whole lot) of these sorts of shells. Initial thought was some kind of ammonite. Searched for mid Devonian and got agoniatites vanuxemi but I don’t get any hits in this formation/location. Still looks right though, although I guess it could be some kind of gastropod? Mostly a little over 5 cm at the largest. Also, they’re generally the same color/consistency, save for this one very colorful specimen (very distinct blue, pink, orange) and I was wondering if anyone knows why it would have preserved that way. Surely the shell wasn’t that color
  3. Tabulate coral ID - Syringopora or Aulopora?

    The attached photo is a group of Thamnopora corals found in the Devonian Martin formation - dolomites of central Arizona's Verde Valley. There is also a group of tabulate corals that I suspect are Syringopora sp.. but some collection notes by others don't show this genus, but they do show Aulopora sp. as found in the same location. See the small worm-like cluster near the center of the image. Can any of you confirm which genus is in the image?
  4. Hello everyone, I have recently purchased some fossil teeth from the sarcopterygian Laccognathus from Latvia, As a result, I have been trying to learn more about the animal and its ecosystem but one thing has stood out to me. Wikipedia states that this fish may have been amphibious, the problem is that the article is rather short and does not state what traits of the fish can lead to such conclusion. I have tried looking for this in other articles and papers but so far have found nothing. Does anyone know where I could go to read about this or if the claim actually has any evidence behind it? Thank you very much
  5. I found several varieties of Devonian corals, including Pachyphyllum, Hexagonaria, Thamnopora and Alveolites near Superior, Arizona. Check out this Pachyphyllum woodmani that reminds me of the painting The Starry Night by Vincent Van Gogh. The painting also inspired a great song by Don McLean: https://m.youtube.com/watch?v=dipFMJckZOM Pachyphyllum lack common walls with their neighboring corallites. The septa grow in a curving manner towards each other meeting in a slightly irregular fashion.
  6. CNY Eurypterid?

    Hello! Recently I’ve had the chance to go fossil hunting for trilobites, in central New York. I’ve been to the hill site in Tully NY, behind the hotel. I was fortunate enough to find a fairly complete Greenops Trilobite, and a few smaller, less complete sections. I spilt open a section of rock, and saw what I thought was part of a large trilobite eye at first. I’m not too familiar with the types of fossils that can be found here, but the texture seemed similar to a small piece of the head of a eurypterid. I’ve never found a eurypterid before, and it’s been on my list for a while, so maybe it’s just me being hopeful. I’m not even sure if eurypterids can be found at the site I was at. I was hoping some one could help identify what I found, and hopefully learn more about what can be found here in CNY.
  7. Iowa Devonian Fossil Help Please

    Found this fossil recently while visiting the Fossil Park near Rockford, Iowa. The fossils here are Devonian in age, and belong to the Hackberry Group/Lime Creek Formation. Have found numerous varieties of brachiopods, horn and colony coral, gastropods, bryozoa, and pieces of crinoid stems, but have never seen anything quite like this. Since it was such a crappy day, I had the whole park to myself except for one guy from Minnesota. Thinking he might be more knowledgeable than myself, I asked for his opinion on what he thought this was. He suggested it was definitely a crinoid calyx. I am not so sure. Thank you all for checking it out.
  8. Trilobite partials, mid Devonian

    Cephalon partial from the needmore near winchester VA, middle Devonian. Looked familiar so I looked it up in the book I remembered it from and it lists it as unidentified, but resembling Lichas. As I was looking at it I noticed below it an illustration that looked just like a couple of tiny partials (pygidiums) I had saved from the same spot. Book lists these as unidentified too, but was published in 1991 so I was wondering if anyone here had any ideas. I’ve found a lot of damaged cephalon partials like this out there so if I know what the rest of the bug looks like, I can maybe keep myself from getting confused if I run into it while looking for something else out there.
  9. Mid Devonian tiny trilo ID

    It looks to me like another eldredgeops, although the glabella looks slightly longer if I look hard enough. I find a lot of those out digging here (outside Winchester VA in the needmore formation) so that wasn’t what stood out so much as it’s size, and I do apologize for not including a ruler I just honestly don’t have one small enough. If it’s bigger than 5mm I’d be surprised. So I guess my main question is, would this have been a juvenile of the species? My understanding was that they gained segments as they age, but this guy looks exactly like the other much larger specimens like him that I find out there, seemingly the same number of segments.
  10. I graduated college back in May, and since my graduate program did not start until September, I was fortunate to have quite a bit of time this summer to explore further away from home. I've been slowly prepping and cataloging over the past couple months, and figured I would share some of my favorite finds that I haven't shared yet. First up is dump piles of Silica Shale (Middle Devonian) in Paulding, OH. My university was not far from here, so this is really where I started fossil hunting. I've been here quite a few times, so most of what I found I already had in my collection. A new find for me, and my favorite, is a nice chunk of Protitanichthys placoderm armor. I visited family near Indianapolis in August, and headed out a day early to visit some classic sites. This is the view from a roadcut in Sulphur, IN that exposes the Indian Springs Shale (Mississippian). My first blastoid and first shark tooth of the day. Can you spot them? A small portion of the haul. Lots of blastoids (the main attraction), horn corals, and some brachiopods, plus a crinoid I have yet to identify. Next up was the famous St. Leon roadcut (Upper Ordovician). This was my second visit to this site. You need to get on your hands and knees to spot the tiny Flexicalymene rollers.
  11. Millerosteus minor Miller, 1858

    From the album Vertebrates

    Millerosteus minor Miller, 1858 Middle Devonian Eifelian Caithness Scotland Millerosteus minor (named after Hugh Miller, a Scottish geologist and paleontologist 1802-1856) was a small arthrodire placoderm, rarely exceeding 15cm. The extinct armored fishes known as placoderms make up what is considered to be the earliest branch of the gnathostome family tree -- the earliest branch of the jawed fishes. Arthrodires possessed jaws but no teeth. Razor-sharp bony dental plates formed sort of a beak and allowed to gnaw on prey. Arthrodires (“jointed neck”) are characterized by an unusual joint in the dorsal armor between the head and neck regions; this joint apparently allowed the head to move upwards as the jaw dropped downwards, creating a larger gape. In addition, it also had an internal joint between its neck vertebrae and the back of the skull, allowing for the mouth to be opened even wider and being able to feed on rather large prey. Millerosteus probably fed on invertebrates such as crustaceans and mollusks or even was a mud-grubber that ingested organic-rich mud for its food. Arthrodires possessed a heavily armored head- and neck-region. The slender fish-like body and the heterocercal tail that extends behind the heavily armored portion is, because it is almost naked or only covered with small scales, rarely preserved. Millerosteus is a rather common fish in the Middle Devonian flagstones around Caithness.
  12. Found this guy today in the needmore formation near Winchester VA. It’s a very productive site but I’ve never found such a well preserved crazy spinous boy like this out there. I’m self taught on all of this and happy to hone my prep skills on standard fair like phacops Eldredgeops rana that I find out there all the time, but this guy is special and rare. At least for me. And delicate. Anyone here do professional fossil prep, and willing to give me a quote? PLEASE SEND ME A PM. The third pic is the mold that the pygidium came from and contains (presumably) the rest of the bug.
  13. Middle Devonian trilobite ID

    Found in the needmore formation just outside Winchester, VA puts him at mid Devonian. Only his pygidium visible but the rest of him (presumably) is still in the rock that contains the cast. The third photo here is the cast, taken at a slight sideways angle to get an idea of how it broke off from the rest of the rock. Hard to tell in the photos but the segments have alternating gold coloration, along with small spine nubs on the tops of the colored segments. I know it’s hard to determine from just his butt. Figure the order is Odontopleurida, closest match I could find was acidaspis calicera, but I couldn’t find a lot of good examples. Another thing, (and I know that this technically goes under the fossil prep board but, you know, while I have your attention) any tips on how to most carefully prep out the rest of him? It’s a fairly fragile shale material and he’s one of the trilos that preserves in a way that almost makes him seem made of the same material as the matrix, so extra delicate.
  14. More New York devonian fish

    Here’s some more upper Devonian fish parts from The shore of Lake Erie. Mostly black Cashaqua and Rhinestreet shale found at Sturgeon Point area. An actinoptergyian skull roof , possible Sarcopterygian caudal fin, placoderm bone fragment, a fish skull piece and jaw (unidentified)
  15. Catskill Fm Plant Material?

    While collecting in the Catskill Formation of Pennsylvania I came across this piece that struck me as a little strange. It is different from other plant material that I have seen/found at the Red Hill site. I ended up bringing it back home just because of how odd it was. Is this perhaps Callixylon? Alternatively it could just be geological. Any help is greatly appreciated. Here is a close-up of the big piece in the middle:
  16. Found this trilobite this afternoon between Capon Bridge and Wardensville. The formation is supposed to be Oriskany Sandstone, but it looked like siltstone not sandstone. Any help on identification? I haven't seen any with these spines in this area. Thanks! Matt
  17. It was about a month ago that our Fossil Club was going to meet at a Devonian location in central Iowa. The first cold weather of the season hit just then and required heavy coveralls to stay warm, so my sights were not set too high for this trip. I decided to make it a 2 day hunt and sneak down to SE Iowa the first day. My goal was to attempt to find some shark teeth from the upper Burlington Formation. The teeth from this location are extremely fragile and will turn to powder if touched with anything but kid gloves. This is a lesson that I have learned from multiple times collecting with little to show for my effort. IF I found specimens, I planned to leave them in the matrix and stabilize before transporting them home. Now I needed to find some! While exploring the Mississippian age rock, I did come across a few specimens that I brought home that were not teeth. A few representative Brachiopods A brachiopod in matrix that I still am not comfortable on its ID As always, I must always bring a rugosa coral home. Burlington limestone is known for its crinoidal content. Here are some typical finds. Like the rugosa, I still can not pass up crinoid stems. The next picture shows the unique twisting stem of a Platycrinites. Now some crinoid cups. I love geodized fossils and this is the first crinoid cup that I have found in such condition! Though the picture is hard to see, 4 different crinoid cups are on this piece of matrix. Another first for me. The next cup is a new one for me. If someone recognizes it, let me know!! Finally, the last crinoid!!!!!!
  18. Hi everybody! Today i want to kindly ask you help for the correct ID of this trilobite. My choice is Morocops ovatus but obviously i prefer to listen the ideas of experts (@piranha @Kane @Tidgy's Dad and more). I'm thankful to everyone who want to participate at the topic Here are the info: Origin: Jbel Zguilma (Foum Zguid), near Alnif, Morocco Age: Emsian, Devonian Lenght: 5.5 cm / 2.16 inches The trilobite is not in my hands, the photos are from the seller. Thanks and have a wonderful weekend!
  19. Holoptychius cf. flemingi scale

    Last Saturday we made a little trip to the Ardennes in Belgium, although we didn’t find a lot , I found a really nice scale of a Holoptychius cf. flemingi. Most of it was covered in matrix, but I did get it out with a mechanical prep. as found: after the prep:
  20. This was not really a fossil hunt, but a lovely trip to Pendleton county West VA... I usually hunt sharks teeth on the lower Potomac in Westmoreland county, VA , but was amazed to be on the south branch of the south fork of the Potomac near Upper Tract West Virginia... it flows north here mostly heading for Harpers Ferry... I was rewarded with great views and some stromatolithic limestone .
  21. I enjoyed an autumn drive through the rusty-red-colored oak forests that blanket the scenic mountains of northeast West Virginia. Two inactive quarries enticed me to prospect a bit. In the first quarry of Ordovician age shaly limestone was this graptolites plate .... perhaps Climacograptus? In the second quarry of early Devonian age massive limestone was this crinoid column base with the attached holdfast. Both specimen photos are as found.
  22. Hi everyone, an interesting fossil was found near Montague NY, most likely Glenerie Formation. Can this be the tail section of a Trilobite? Can anyone help with species ID if possible? Thanks to all that can help
  23. ID Help

    Hi, I'm not a collector of fossils. I found this about 20 years ago. It was from the Niagara escarpment at Inglis Falls just outside of Owen Sound Ontario Canada. According Wikipedia the escarpment's caprock is dolomitic limestone and is composed of an outcrop belt of the Lockport Formation of Silurian age. I thought it might be a winged insect but if it is Silurian or Devonian maybe a water based creature. I'm not sure if it is a wing on top or part of something else. There appear to be a few small and very small mollusc shells embedded in the rock although they aren't clear in the photo. In the side strata there is quartz as well as other layers including a dark/black layer. Whatever it is appears to be missing the head. There does appear to be another leg on the rock top as well. Thanks for you kind assistance. Best Regards, David
  24. Paleoniscoid fishes

    Here’s a upper Devonian paleoniscoid fish I found in 18 mile creek - Erie county,NY this spring. seems to be similar to fish found in younger stratigraphy Linton deposits from Ohio area. Been hard to find any specific info on Devonian fish found in New York, perhaps a rare find? Has anyone found anything similar in western NY?
  25. Its been a long time since I last posted any finds, so I thought I'd show you folks what Ive been finding so far. Ive been out a lot this year, and have done quite a bit of exploring. I haven't taken pics of everything yet but Ill add to this as I do. This past summer I took a trip to west Tennessee to an exposure of the Coffee Sands, a Late Cretaceous formation. I was able to find the site, but unfortunately, I found no fossils there. Luckily there was an exposure of the Lower Devonian Birdsong Shale nearby! This site exposes the 'brachiopod zone' which is the bottom of the formation. So as you can probably guess, brachiopods were every where! By far the most common was Atrypa “reticularis” , they were all over the place. Discomyorthis oblata was also common Heres a favorite of mine Kozlowskiellina tennesseenis, They are very decorative. cont...
