  1. China Trilobite ID request #5

    Good morning. Here is the fifth in my series of eight unidentified trilobites. Yes, the usual lack of additional information precludes me providing any ....:/
  2. Hello everyone! A friend of mine was just given a group of fossils from a relative and has very little/no info on them. Through searching through this forum, we were able to I.D. most of the pieces, but this one we were unable to recognize and were hoping someone could help. There is no locality information associated with it unfortunately. Thank you everyone for your time/help, I really appreciate it!
  3. Tooth or barb?

    Good morning all. I am still digging through my unidentified draw again and I came across this "tooth" or "barb", not sure. It looks like a tooth to me, maybe you can help. I don't have any information on this item as it was given to me many years ago by a friend.
  4. 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.
  5. Pennsylvania Field Stone footprint?

    I know this is an old thread sorry. I have a very similar fossil that I found in a pallet of Pennsylvania fieldstone back in late 2010/early 2011. I have kept it all these years always meaning to research it and just this morning stumbled across it and decided to do some googling and happened to find this thread. I really do believe mine is two or three digits of a human hand or possibly a dinosaur with a very similar skeletal structure in its feet.
  6. I have shown several of these things to a number of micro-paleontologist, paleontologist, geologist and marine biologist and no one seems to know for sure what these specimen are. They were found in a sandstone boulder with bivalves fossils, they range in size from about 3mm to about 0.20mm. I'm told that they are most likely a new foraminifera species. Anyone have a clue???
  7. I am assuming that this feature is just geology, but I would like a second opinion on this if possible. My eyes do wonders at seeing what I want to see instead of what is actually there. Thank you. This was found in Douglas County, Missouri, USA in the Roubidoux Formation. The feature in question measures 84x31mm. The host rock is 20x12.5cm. It was found near a seasonal creek bed where gastropods, rugose coral and crinoids have been found. Numerous trace fossils have been found in the area also. Thank you for your time and help.
  8. Here are a few unidentified fossils found a in a creek bed that cuts through late Cenomanian marine shales. There is a dense marine bonebed nearby, pieces of which can be occasionally found in the creek, so I have a feeling that at least the first example might originate from there. The bonebed is composed mainly of teeth, though there are fragments of hesperornithine and marine reptile bones in it as well. The only reason I'm hesitant to assume that this piece is from the bonebed necessarily is that it's preserved quite differently - while the bones found in the bonebed are black and quite brittle, this piece has a dense, chalky feel to it - never mind that the end of it looks nothing like any fossil bone I've seen. My guess it that it is an errant fossil from one of the other slightly fossiliferous layers in the area. You'll notice first that the piece tapers from one end to the other. The diameter is about 10mm at the wide end, and 7mm at the narrow end: The narrow end has this odd arrangement of concentric circles and striations, unlike the hollow profile I'm used to seeing in the hesperornithine bones. edit - here's the mostly featureless wide end: Finally, you'll notice that the length of the piece has two shallow grooves that seem to taper slightly toward each other. You can see them in the following photo on the top of the piece, and on the sides of the piece in the first and second photos. Here is the second piece. It is embedded in a fine-grained sandstone. Notice the fish scales that are typical in many of the rocks from the area - as for the piece itself, my best guess is fish coprolite, but I'm open to other ideas. Magnified: As usual, I can provide more photos at request.
  9. Dinosaur Coprolites from China?

    These are being sold on online for $10 as dinosaur coprolites from China. Any opinions?
  10. Unknown Limestone Fossil

    Possibly a burrow? Found beneath the Chinle formation on US89 in northern Arizona. 4 inches long, 2.5 inches tall, with a slight curve and a flatter bottom side. The rock looks like limestone, but was found on a flat wash without similar rock in the nearby area.
  11. Unknown teeth

    From an estate sale that I acquired some rock boxes. Here are some teeth. The only tag that IDd them was .... wait for it.... teeth! Any ideas? Again, these don't go with my collection but would be nice to ID a little more.
  12. Maybe someone can help identify this

    Found this strange chunk of something in a creek in southwest missouri, it weighs 6.3 grams feels like their is nothing in your hand when holding it, it is somewhat covered in something white and has a few tiny black spots on the white stuff and kind of has a sulfer type of smell, I know it's not a fossil but I was really hoping someone might have an idea of what it could be? I thought of maybe old molted lead that cooled but I figured it would be alot heavier.
  13. Sea stars / starfish?

    Years ago bought some rock boxes from an estate sale in California. Included were some fossils I just don't know anything about. Most had vague or no IDs. The larger of these Sea Stars is approximately 6.5mm across. Gonna post a few here just to see if anything interesting although these have no connection to my collection.
  14. Vertebra

    Hi guys this is listed on our favourite auction site, it looks pretty genuine to me but it is unidentified, it reminds me of crocodilian material, what do you think thanks and merry Christmas will
  15. Fossil ID

  17. Turtle ID please

    Good Evening folks. Can anyone tell me what species this turtle from South Dakota is?
  18. An Echinoid from Morocco?

    These were in one of those sets of mixed fossils you can get. Must've first got them over 10 years ago. Anyway, since most of them were from Morocco I assume this echinoid is too, as it has a similar looking matrix to the others. All the label says is it's an Echinoid from the Cretaceous, but as some of the other labels in the set were clearly wrong it could be from another period. Its one of the last fossils from this set I've been unable to identify, so I'm hoping one of you guys has one or knows the genus and where it is indeed from.
  19. Messy fossil help

    Ok, where do I start on removing this fossil? I am a beginner so where do I start? What should I remove first? Should I even bother?
  20. Bryozoa Clump prepped

    Hello gang, This is one of the first fossils I prepped a long time ago. It may not be the best job, but I still like it. I know it Bryozoa, but not much else. It was an unprepped flea market find. Any ideas?
  21. Dire Wolf?

    Here is another one of my impulse purchases. Loved the look and OK price. But, is it really a Dire Wolf partial skull. Information only said "found in North Dakota by father 15 years ago". Seller didn't have a fossil knowledge. Help!
  22. What is this, plant animal?

    Here is another one of my impulse purchases that caught my eye. Unfortunately I purchased this many years ago and cannot fine my records... Can anyone help?
  23. Another odd one

    Another odd one! It's the same kind of surface I've found before, tiny spikes and bumps, and the previous one was suggested as some kind of lichid.
