  1. hi everyone this is matthew again today in the creek I found this strange rock with a lot of red dots all over it does anyone know what it is ? here is a photo
  2. Shale ID?

    Hey all! I got out today to hang out on the beach and ended up searching a shale scree not far from where I parked in santa barbara, CA. This looked like it had fossiliferous potential so I grabbed it along with a good amount of nice malachite. A tube-like shape with white crystal-like openings which measures about an inch in this piece of shale. Curious to se what you think and thanks as always!
  3. Hi all, Heres the fourth tome of my fossil collection, and not the least : Trilobites - All collected by me but one. hope you enjoy https://flic.kr/s/aHsmMbxqkV
  4. Hi, I am doing an emergency Fossiling trip to Western New York State. My entire family is very high risk for corona, and I am just leaving my college, where there were a few cases of it. Although I technically Do not need to quarantine, I am planning to spend at least a week alone before I go home to make sure I am asymptotic. That being said I will be spending the week hunting the shakes of New York State. I have been to deep springs and I just wanted to make sure that it is still viable. I am also possibly going to go to penn Dixie, but my main goal is to isolate and get some quality fossil hunting done. Any possible fossil hunting spots would be much appreciated in that area or the area of penn Dixie, if they are spots that are not densely populated
  5. Tiny Bilateral ??

    Sorry about the tag ambiguity but I’m at a loss. This was recovered from an old fossil collection sold retail in about 1955. Any ideas would be helpful. Family? Genus? species? US Penny (and cat hair) for scale. Thanks, Glenn
  6. Black Shale things

    Not sure what these are. There was loose shale near where I dig scattered on the ground. It had different things in it than I’m used to seeing. Maybe it was dumped from a different part of the strata, but shouldn’t be much further away. I’m not great with fish parts, are they maybe fish parts? Should I scratch them out or maybe some vinegar? There are a few other pieces that look tooth/horn shaped.
  7. Seed pod ID request

    Good afternoon folks. I have a seed pod that I purchased about ten years ago from Portugal that in dire need of an identification. All the information I have is it was found in Serra de Valongo, Portugal. And it was found in shale???? Help please.
  8. Can somebody tell me what this matrix is

    Can someone tell me what that rock that contains these plants is. Ash maybe? its a shale type material almost flint it feels like it was found in south central WV in Lincoln county it comes from the pennsylvanian era i believe.
  9. Unknown Ordovician organism

    I recently acquired an Ordovician rock from an antique shop near my house. It is a dark shale with cryptolithus and what I think are isotelus trilobites on it as well as brachiopods and graptolites. I am unsure which formation or even where it is from but it has this strangely shaped creature that I have not been able to identify. The creature has tiny indents all over its surface.
  10. Pa fossil. shale with large shell. while removing excess layers found a sort of fish. is not a clam or mollusk. Devonian period rocks location.both sides of fish in picture.
  11. Trilobite ID help

    Hello everyone. Can anyone tell me what type of Trilobite this is? All I know about this fossil is it came from New York in a batch of unprepped fossils.
  12. Went to a fossil garage sale, were the person was selling off his collection, this fall with low expectation. Found what turned out to be a very nice specimen of a Devonian Crinoid after prepping it out. My friend Tom W. tells me it is more than likely an Arthrocantha carpenteri. Wish I knew what quarry it came from, it wasn't labeled.
  13. Florissant Fossil Quarry Fun

    Hi, I'm a new member here, though I've read threads on the forum for years. In the warmer months, I'm an entomology geek, and I'm usually out trapping moths at my backyard UV setup or snapping pictures of dragonflies and the like. I'm also a longtime rockhound and paleontology fan, and it's the combination of my love for bugs, our cold-as-all-get-out winters here in MN (in winter there are no bugs), and the availability of fossil shale from the private Florissant Fossil Quarry that brings me here. Long story short, I'm interested in finding some fossil insects, and I've recently purchased several pounds of shale from the private quarry. I've already found a gorgeous fossil leaf (presumably an extinct elm, if my research online is right; that's the second photo, taken via smartphone), and I think I've found a fossil fly of some variety. My question: Is it wishful thinking? This photo of the perhaps-bug is through a Aven digital microscope. The magnification on it isn't bonkers (only 10x-50x), but it is still a heck of lot better than with the unaided eye. (This thing is tiny. If need be, I can find a metric ruler for reference.) OK, thanks, and take care.
  14. Where I'm looking for fossils

    Thought i'd ask about an area I revisited to see if it seems like a good spot to start looking for fossils. It's a mine dump, most of it seems to be shale I think (is it?) Means I don't I have to dig, but most of it is pretty shattered.
  15. Possible Paleoniscoid Skull Roof

    Hi all, This specimen was found in a black shale layer that lays directly and uncomfortably upon the Duquesne Limestone, which is Late Pennsylvanian age. It was found in the suburbs of Pittsburgh. Both the shale and limestone are filled with vertebrate fossils, especially the scales, teeth and spines of paleoniscoid fish. As far as I know there is no species list from the shale but Elonichthys has been reported. I know skull roofs can be very diagnostic so any rough estimates of genus would be very helpful! I apologize for the picture quality, my phone is a brick.
  16. Footprint?

    This rock was found in Upstate New York, almost certainly in Devonian shale. It looks sort of like a footprint, but I wasn’t aware that large dinosaurs even existed in the Devonian, so it is dubious. Any opinions? Thanks, Evan.
  17. Middle Devonian Fauna

    Here’s some fossils I’m working on from 18 mile creek in Hamburg,NY. They’re in pretty dense hard silica shale. Any ideas on identifying them?
  18. First trip to Centralia, PA

    I had my first taste of the Carboniferous period. I made the trip to Centralia PA for a look at the fossils there. I went to coal deposit up the road from the cemetery on 2nd street ( pic below ). Centralia was not a "ghost town" not when I was there. There was a lot of people around. Many looked like they where their for the Graffiti Highway and other for some kind of four wheel event across the street from the spot I was at. The Shale was very soft and I had a hard time picking up anything bigger than 2 inches. I pulled away 3 layer but still had the same problem. I don't know if it would be them same if a kept going. Over all the sit was easy to find, and had a good view. With many fossil to pick from.
  19. Hi all, I have been more or less away from the forum for the last few monthes. Life has been hectic. And if i still managed to go on the field quite a lot, i did have any time left for the rest (writing, taking photos, processing stuff, labelling etc). Nevertheless, i finally manage a quick photo session. As an appetizer, what is prolly the best piece for quite some time. A double trilo, Eodalmanitina sp, one preserved with his caudal spine. So 2 rocks as a starter . I had to sacrifice part of the 2 counterprints, to unveil the opposite trilo... Regards.
  20. Trilobite ID

    Hello, I came across this trilobite after I had shale delivered from a local eastern panhandle WV quarry. It was found with several crinoid stems. Any help on ID would be greatly appreciated. Thanks
  21. Shale fossil print

    Hello! I found this odd looking fossil the other day on a river bank in Toronto after splitting the shale. It seems to be possibly be a coal imprint of some sort. Not too sure what it might be. Let me know what you guys think: Thanks for the help!! -Em
  22. coral?

    Today I went down to fossil hunt in Tully, New York. I stumbled across this and thought it was a horn coral, but I hadn’t been finding any corals. I had been finding a bunch of crinoids so I was considering a crinoid calyx, but I still had no clue. Any insights are greatly appreciated!!!
  23. This summer I was once again able to look for fossils near Newberry, MI in a degrading hill filled with drift. In my research recently, I came across a paper on the Collingwood formation drift in Newberry, and was excited to find exact descriptions of some of the layered rocks found there. I am including photos of one of them, split into its layers...and the orthocones revealed in thos layers. The orthocone has a very thin shell of some kind....they are always found flattened and usually with that line down the center indicating what was once rounded has been squished flat. In the 4.5 " orthocone showing (the third image and about 6" overall) even the open edge presents a somewhat curved opening. usually it is squared across. Over the years I have found these triangular shaped creatures filling the shale...from 1/4 " long smattering of them all over a hashplate, to the ones that average 4 or so inches. I have not been able to figure them them out. The interesting paper I read doesn't mention them, which was a surprise to me since they are so plentiful. At any rate, If someone has a suggestion I would appreciate it. The other thing I am curious about, is the geologic process that formed this rock...for each of them, the split layers reveal creatures...in one of my rocks, each layer is filled with graptolites. So what was the process by which the layers formed....rain storms that roiled the sediment and trapped a layer of animal...followed by a week or month or day or year storm that layered another 1/2 inch of sediment and captured another layer of creatures....and how did this layer than get broken up into cobbles....(the animal remains found in each of the layers sames to be consistent with all the other layers of each, so I am assuming a rather quick succession of silt was laid down....in a somewhat regular pattern.
  24. Hello everyone, I've had a lifelong passion for fossils but I'm a relative newbie to collecting, having only done it for the last 3 years. Most of my previous fossil-collecting trips were in NC, where you find sharks teeth and shells by sifting through creeks or looking through mine deposits. I know very little about how people do it out west, which has turned out to be a big problem. On a recent vacation to Colorado, I looked around Florissant Fossil Beds and also ordered a shipment of fossils from the quarry. The shipments arrived about a week ago, and there's some pretty interesting imprints on the surface some of the rocks, namely possible Sequoia and Cedrelospermum, as well as another rounded leaf. I got an X-Acto 1 knife and started splitting yesterday. The problem is, even though I'm trying to follow the instructions of the sheet sent with the fossils, I haven't found many fossils, and worse yet I've accidentally lopped off the tops of the sequoia and Cedrelospermum leaves (it's nothing a little superglue can't fix, but still). The remaining parts of the leaves are also in a very precarious position: they are on very thin layers and I can't continue splitting the shale without possibly causing damage to them. I'll share pictures later. People who've successfully found fossils at Florissant, what are your secrets to finding things and not causing damage to fossils that are in the same rock that you're splitting?
  25. Penn Dixie Trilobite Preparation

    I have several good Eldredgeops rana specimens from Penn Dixie Fossil Park, and they were fairly clean when I hacked them out. Unfortunately, there is a lot of shale stubbornly stuck in the groves and crevasses of the trilobites. I have access to a dental sandblaster, but I'm not sure if it's safe to use. Any thoughts?
