  1. Back again! It's too much fun figuring things out. I'm running out of shadowboxes, though, so will have to wait before tackling my next batch. 1. 2x unknown metacarpals/metatarsals as identified by our guide. Both are 'spongy'.

    Fossil found on California beach

    Found this on a rocky beach here in Southern California, wondering if it is fish bone or a scale, or plant material?
  3. Please help. I’m new to the area, having retired from Europe in October ‘23. I’m finding lots of teeth but also some odd items. Can anyone help ID this odd little fossil? It’s about 3/4 “ X 3/4”. Thanks
  4. Found this for sale somewhere, they are advertising it as a gar scale, but I don't think it is, although I could definitely be wrong. My first thought was maybe a scute of a crocodile, but I think that is also not it. Any ideas/ Thank you so much everyone in advance!

    Kem Kem Bone Grab Bag

    Every year at the Denver fossil show it seems like I pick up some unidentified Kem Kem material. This is because for one it’s cheap, but also because it’s kinda fun to investigate this material. Here are eight pieces I picked up as a bulk set. I have some idea about identification on each of these but would love to hear other’s input. In the following pictures I have the top row being archosaur fossils and the bottom row being fish fossils. My guesses: 1. Caudal(?) vertebra centrum. Croc or theropod, but probably croc. 2. Croc dorsal vertebra 3. Croc centrum 4. Theropod pedal phalanx. Specifically, the distal-most phalanx of toe 1 (the “dew claw”). Narrowest ID I think I could guess we would be Ceratosauria indet., should probably be labeled as Theropoda indet. 5. Two fused fish vertebrae. Are these identifiable any more than this? 6. Gar or gar-like vertebra 7. Chondrichthyan fish vertebra. Maybe Onchoptistis numida? Can that determination even be made? 8. A gigantic ganoid scale. Any guesses just based on size? I’m unfamiliar with all the monster fish in this rock unit. Thanks :)

    Best Coins as Scale

    I found several coins that would make good scale since they are very close to 2 cm in diameter. My top pick is the 10 cent Euro which is 99% of 2 cm in diameter. Other good ones include the British farthing at 20.19 mm in diameter. Others probably exist, but have less supply. The secret is to write 2 cm or 20 mm on the coin. Alternatively, you can mention the size in your post. Any other worthwhile coins? I have heard that some of the square holes Chinese coins are 2 cm across. @Coco

    Bone ID

    For the longest time I have puzzled over this strange bone. At first of course I thought it was a "Hynerpton scute," because I have a memory of finding it somewhat near where the holotype was found and no papers picture them, so I couldn't compare. Recently I've doubted its identity as I've researched Ichthyostega scales and scutes, but have no idea of what it actually is. Any ideas? On the imprint nearest to the camera a texture can be seen, shiny smooth with little circular rounded bumps that are the negatives of pores. Size a little less than 1.5 cm from end to end.

    Mazon Creek Coelacanth scale

    I had this concretion open today. I immediately noticed what I believe is a coelacanth scale, but on closer inspection there looks to be some other bits that might be related. Any thoughts? @jdp @RCFossils

    Fish scales

    Hi Forum, i'd like to post to you this specimen i found in Omhden (DE). It seems to me like fish scales, but because i'm a complete beginner i'd love to receive your opinion Sorry for low quality photos, i have tried different ligths. i'll do my best with better camera if you need. Total length 7cm, width 4cm Thanks a lot Paolo

    Holoptychius scale

    From the album: Misha's Late Devonian Fossils

    Holoptychius sp. Fammenian Ketleri Formation Venta River Latvia
  11. Hi! I’m still trying to identify one fossil from a particular unit of Pleistocene/Early Holocene lacustrine silt from my hometown of Saskatoon, but I figured I would look away from it for a bit to try and identify another fossil from the same unit I’ve been unable to classify. I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the other in profile, showing its umbrella-like, protruding outline. All photos are taken through a microscope with my best camera currently available, an iPhone! My main areas of middling expertise are arthropod and vertebrate fossils, so I have no idea what this is! I have briefly studied fossil foraminifera and diatoms in the past, but it looks like nothing I’ve seen in those areas as well. It reminded me of a small limpet, some type of seed or spore, or perhaps even a strange fish scale, but I have no formal suggestions. I’d highly appreciate any help! I will try to supply any additional information you may need. Thank you!
  12. Hello there! I made my way down to Myrtle beach SC and found a few interesting bits that I would love some help identifying. Thank you for any information in advance! First off we have this scale-like piece (actually no idea what this could be, I've never seen anything like it before): Then we have what I think might be a shard of some kind of mineralized shell fragment? This seems similar to some fossilized turtle shells I've found in the past. Lastly, what might be (really guessing here) a part of a sea robin skull? Please take that with a grain of salt. (Thanks again!) Thanks again Ya'll!

    Dermal denticle

    Hello! Is it possible to identify this scale? May be to order, or family, or genus? Max size: ~ 0,5 mm. There is some relief on the sides of denticle (see arrow). Age: Eocene (Ypresian or Lutetian). Location: Ukraine. Thanks in advance!

    Fish scale in limestone?

    Is this a fish scale? Or just a concretion? It's 14.5mm in length. Glacial erratic limestone, found near Jeziorsko, Łódzkie, Poland.

  17. I sculpt scale model dinosaur skulls (and more) on a popular 3D printing service. I put a lot of research and effort into getting these as accurate as I can. These are my personal copies, painted in acrylic with D.I.Y stands.

    Mystery Devonian Fish

    I found this mysterious fossil in Richland, Michigan, and don't know what to make of it. It appears to have a fish scale and lots of bone fragments, as well as a piece of coral, in smoothed (Devonian?) sandstone. I don't know my fish very well; can anyone help?
  19. Hello everyone! I have wanted to create myself a dedicated scale to use for photographing fossils, as I too often forget to include a scale in my photos and I think that a special scale would be more interesting than just a ruler, it could also be helpful for objects that are not as flat for scale in 3 dimensions. My initial thought was to make a cube, but I also wanted to include both imperial and metric units so that everyone on the forum can easily tell the size. So for my first design I decided to try making a cube that has dimensions of one inch along all sides with a 1 cm3 cube cut out of the corner. This design was nice and quite simple too, but I think it could still be improved. I am just not sure exactly how. I was thinking about including a small ruler along both the 1 in and 1 cm side so that you would also be able to see mm and the smaller units, but that might be too fine for my 3D printer, although I'll need to try it first. I just wanted to ask here as well if anyone has any ideas of what would make the best possible scale for use here on TFF. What would you want to see it this was a scale included in a photo of a fossil or one that you were using yourself? Thank you for your consideration and any suggestions, Misha
  20. Everyone please use an internationally recognised scale in your images. Coins aren’t good enough. How big is s rupee, or a farthing? I dunno. Of course a marmite jar is the same size worldwide Vegimite is NOT internationally recognised. I hope you’re taking notes @Jesuslover340

    Scale from Al Ain

    Hello, I found this in Al Ain, United Arab Emirates after breaking open a soft limestone rock. I assume it's eocene in age. The orange color immediately grabbed my attention. I took some photos of it using my microscope and spotted a second, similar object opposite the first. I scraped a bit of the matrix off to reveal more of the second one.
  22. Good evening all and thanks again for everyone's help and patience with my finds....to that end, here's another one. Stark shale between Winterset and Bethany Falls limestone Pennsylvanian. I'm guessing a fish scale or shark denticle (it appears to be inversely ridged or elevated in deeper layers). I would still like to clean it a little better (the brown-filled divit) but wanted some thoughts prior-it will help me decide how to clean it. Thanks all!! Bone
  23. Looking for conodonts, I found and meticulously cleaned this object-at first I thought insect wing, but then fish scale, then plant, then, nuthin special. Thoughts again appreciated!! What say ye? (Stark shale, between Winterset and Bethany Falls, Pennsylvanian) . Bone
  24. Hello everyone, The Osteolepis macrolepidotus fossil I recently acquired came with a little surprise, It has a a fairly large impression of a cycloid scale with it, I was wondering if it was possible to identify it. I know lungfishes have these types of scales so maybe Dipterus? I am really not sure, I have been trying to look at the scales of fish found there but have not found many good references. The scale is about 1 cm in length. Any help would be appreciated.
