  2. NJ Cretaceous Coral

    If it has radial symmetry it isn't just sand filled which is what I meant by "through and through". If you look at the broken end of a belemnite you'll see radial symmetry. Imagine that sorta fibrous crystalline structure partially dissolved away and then leached and weathered within rust colored sand. The sand would still cling to the belemnite and indeed sand in the Mount Laurel/Navesink makes a mold for a belemnite when it is completely leached away.
  3. Your piece is Composite. The teeth are real, but the rest is just carved bone glued together.
  4. My first bone prep...

    Very nicely done prep job (and stand)
  5. Hiodon Falcatus?

    The Image is from @oilshale's collection=
  6. Looking to identify this beach find! A tooth perhaps?

    Yeah... what @digit said.. And also
  7. Congratulations! Spectacular specimen.
  8. NJ Cretaceous Coral

    I'm thinking the concretion may be in the specimen. Sometimes the key is to find something like it but not as far gone.
  9. @jnoun11 Will you join the discussion requested above and comment on the piece in this topic. I am curious, if any techniques you know to be employed, are readily visible in the piece above and how best to detect them, i.e. what to look for. Thanks.
  10. Turtle bone?

    Im my opinion its very difficult to identify a bone fragment like this.
  11. Gomphotherium on the Peace River

    Those two pieces look as if they might fit together. Have you tried? Don
  12. NJ Cretaceous Coral

    Yeah it has radial symmetry I should’ve mentioned that. But don’t bryozoans have that symmetry as well? What do you mean by that?
  13. Ptychodus Id Quick Guide

    Gorgeous teeth !
  14. Today
  15. Gomphotherium on the Peace River

    I run in my personal jet, then take my helicopter and i will be landing in your garden at six o'clock, Florida hour.
  16. About the location, there are no Upper Cretaceous continental deposits in central France. French dinosaur eggs from this period (mainly Megaloolithus and Cairanoolithus, more rarely Prismatoolithus) come exclusively from the extreme south of the country, from the following five departments : Var and Bouches-du-Rhône in the Provence region, and from Ariège, Aude, and Hérault in the Occitanie region (which brings together the two former regions of Languedoc-Roussillon and Midi-Pyrénées). Complete eggs (often crushed in marls and clays and often better preserved in sandstones) are known in all these departments with the exception perhaps of Ariège (in this department discoveries are rare today). Without embryo remains inside the eggs it is not possible to assign them to a particular genus. Especially since Hypselosaurus has not been a valid genus since a long time. It's another subject but other titanosaurs are better defined in France : Atsinganosaurus velauciensis from the middle Campanian or from the beginning of the upper Campanian (local Begudian stage) from Velaux in Bouches-du-Rhône, and Ampelosaurus atacis from the lower Maastrichtian of Aude. And there are at least four other species whose description is in progress : a second taxon from Velaux, two taxa of the late upper Campanian of Pourrières in Var (the type locality of the abelisaurid Arcovenator), and a taxon from the upper Campanian-lower Maastrichtian (age uncertain) of Cruzy in Hérault. Some bones suggest the presence of additional species but which are not yet known by sufficient remains to be named. To compare here some photos from the web of French dinosaur eggs from different localities : From Cruzy (Hérault) : A dinosaur egg laying discovered in 2000 in downtown Aix-en-Provence (Bouches-du-Rhône) : Egg from Rousset-sur-Arc (Bouches-du-Rhône) : Some eggs from Mèze (Hérault) : See the Musée Parc des dinosaures de Mèze
  17. Turtle bone?

    Hello! Is it possible to identify this bone? Cpould it be turtles bone? Scale in mm. Western Ukraine, Lviv region. Neogene, Miocene Thanks in advance!

  19. Fossil ID Chubutensis

    Thank you, I think I'll pass on this then
  20. @Praefectus @Troodon Hello, I am trying to visualize the mechanics of the tooth replacement that is cited by you three respondents. Are you all seeing crowns glued on to donor roots; or rooted teeth (with replacements) inserted into an orphan jaw section? Do you visualize the jaw fragment in situ, as dug or do you suspect it is not native to the matrix? Do you suspect the matrix to be constructed (composited sand) as in the horrid, neatly laid out jaws/teeth frequently seen? Thanks for any additional comments/insight.
  21. Another Mazon Creek Collection

    This is a Belotelson preserved in a dorsal view. Side note, someone else found this concretion before I did, cracked it with a hammer and it broke on a plane where the fossil did not exist and dumped it for me to almost discard but freeze/thaw anyway.
  22. Another Mazon Creek Collection

    Next are a couple of colored Annularia species I like how this one preserved in 3 different colors, making it look a little like fireworks.
  23. Amphiplaga brachyptera?

    I agree with the other comments, I found one back in 2013 when I first went out west. Had the same well preserved skin impressions and the same fins.
  24. Winner of the 2019 Vertebrate Fossil Of The Year

    Congratulations! That's a really cool ichthyosaur
  25. Another Mazon Creek Collection

    This is my best and favorite Essexella example
