  2. Dinosaur egg - real or not?

    Given the length, this egg has the morphology and size range of Macroelongatoolithus. However, those genuine ones I've seen are always flattened or crushed and never perfectly rounded like yours Macroelongatoolithus eggs in the Naturhistorisches Museum Wien Eggs at the Geological Museum of China Macroelongatoolithus cast from BHIGR Even on the off chance this is genuine, I would stay away. The quality and poor preparation just isn't worth it
  3. Fossil ID

    Where is the first specimen from? The second looks geological, and yes the third appears to be a coral.
  4. Please help me ID some fossils I found east of Nashville

    With the new picture of the first specimen, it definitely looks to me to be a lot of bryozoan pieces. Probably some other bits in there as well, but mostly bryozoa. Just like @Tidgy's Dad I thought coquina at first glance on the second, but I can see how it might also be bryozoa. Clear pictures of other angles would help decide.
  5. Need help identifying this fossil

    My neighbor found this specimen in a gravel parking lot at his work in Fort Worth, Texas. Is this a Crinoid stem piece? The hole goes all the way through.
  6. Fossil ID

    It almost looks like a shark vertebrae, but still a little hard to see, maybe a measurement will help a little bit.
  7. Thanks so much! I tried to upload more examples but it wouldn't let me I'll try to add a close up here.

  9. Quick guide on isolated Tyrannosaur teeth

    I don't think they were commenting on the validity of the paper. Just generally discussing how paleontology changes with time.
  10. What do you think this is?

    Apparently, I misunderstood the original description by inadvertently reading that this was not a Cyclus. In any event, Cyclus radialis also matches these morphological features. Apologies for the mix-up! Feldmann, R.M., Schweitzer, C.E. 2019 The enigmatic Cyclida (Pancrustacea): morphological terminology and family-level classification.

  11. Petalodous Teeth

    Love Petalodus teeth thanks for posting.
  12. @Fitch1979 Thanks for the feedback I tried to zoom in and edit a bit, wish I could get clearer pics, I'm not sure if this helps.
  13. Replaced Tip

    It seems to be glued a little off but I’d say those are the associated pieces. There are ways to attempt to straighten them with multiple threads written on the subject here but it’s a good tooth nonetheless.
  14. Replaced Tip

    Yes it seems to have been repaired at one point. But the tip seems legit. I don't see any red flags that this might be a composite. So a pretty nice tooth.
  15. Fossil ID

    The best I can take I’ll try to take better ones tomorrow in the light.
  16. Fossil ID

    I’ll try to get better ones but it’s so small it’s hard to get a good photo.
  17. Fossil ID

    Your first photos are too small and blurry to make out any detail.
  18. What do you think this is?

    Ventral cephalothorax of a trigonotarbid. This paper has some similar examples: Jones, F.M., Dunlop, J.A., Friedman, M., Garwood, R.J., 2014. Trigonotarbus johnsoni Pocock, 1911, revealed by X-ray computed tomography, with a cladistic analysis of the extinct trigonotarbid arachnids.

  19. Quick guide on isolated Tyrannosaur teeth

    Not sure why everyone is piling on but I find that paper very valid and it makes several key points that address the initial topic. 1) "in western Canada these tyrannosaurid taxa are temporally separated: G. libratus and D. torosus are reported from deposits that are middle to late Campanian in age, whereas A.sarcophagus is reported from late Campanian to Maastrichtian deposits. ( point here is that its easy to distinguish A. sarcophagus from other tyrannosaurid teeth) 2) "However, quantitatively separating isolated teeth of G. libratus from those of D. torosus may prove to be difficult, given the temporal co-occurrence of G. libratus and D. torosus combined with the morphologic similarity of their teeth" (Point here is that you cannot distinguish teeth between G. libratus and D. torosus) @Mark Kmiecik @Tidgy's Dad @Runner64
  20. Fossil ID

    Hi i I was wondering if anyone knew what these 3 fossils are, Thanks!!. Vertebrae? Unknown McCoy Brook Formation Nova Scotia (Triassic) perhaps spines of some sort?. Coral? Bois Blanc Formation (Devonian)

    Now it's working! Must have been a phone reception glitch.
  22. Please Help - Building a Drawers for Fossils

    It works for me

    @Sagebrush Steve This is all that comes up for me. The link just blinks.
  24. Bone or rock in NJ Cretaceous stream?

    Look for striations and/or porous structure. Compare with specimens that are definite bone in order to rule out stuff like slag that may appear like bone. Experience helps.
  25. Petalodous Teeth

    Thanks for sharing! I learned what a Petalodous is today. Very cool!

    Here is a thread on a cabinet I built a couple of years ago. There is a link to the plans near the end of the thread.
