  3. How to ID Fossils

    There are > 100.000 fossil invertebrate species described in the literature. Its an near invincible task, to comprehend them all. Therefore, the most important piece of primary information is formation. From which rock formation does a fossil come from? This restricts the amount of species usually to a few hundred, often only a few dozen. For many, many formations, papers or even monographs are published, describing the fossil content or at least some fossil groups in them, eg. brachiopods, trilobits, etc. Try googling the name of formations your fossils are coming from. For better results, you may include the word "fossil" and you could also use google scholar: https://scholar.google.at/ Good luck, and please share your results with us! Thank you! Franz Bernhard
  4. really not common samples,to ID and many other in the big boxes
  5. New Primitive Hadrosaur From Texas

    Aquilarhinus is another new addition to the roster of hadrosaurids from the late Santonian-early Campanian of Laramidia, which includes Gryposaurus latidens and Acristavus (remember that the Aguja Formation spans several million years, like the Two Medicine Formation). Note in the cladogram for Aquilarhinus that the Big Bend kritosaurin is a different taxon than Aquilarhinus and comes from the upper part of the Aguja Formation. Since Hadrosaurus has been recovered at the base of Hadrosauridae, it is probable that some basal hadrosaurids entered Appalachia from Laramidia about 90 million years ago.
  6. An other neuropteris Heterophylla
  7. Hi Misha;All kind of fossils i still not have,i like a lot plants,invertebrates(brachiopods),carboniferous fossils.......and cats also(but i have two already ) A Neuropteris frond with nice CALAMITE CONE - PALAEOSTACHYA PEDUNCULATA
  8. These are lovely, what would you like in return?

  13. How to ID Fossils

    So I've been collecting fossils for a few years now, i have a bunch of ammonites, sea urchins, mollusks and plants but I have no idea where can i learn what exact species they are. I'm wandering if there is any books or sites to which you can point me so I can gather some knowledge . I know there is an ID section in this site but I want to be able to tell what species I have found, myself. By the way I'm from Europe.
  14. From the westphalian of Northern France,I would trade these large plates for other fossils i still not have:) A Lepidodendron trunk imprint and a stem
  15. Yet Another Phytosaur Prep

    Nice stand too.
  16. Hadrosaur Humerus Repair/Prep

    Hmm, better stock up on chewing gum. I'm sure you'll do your best and show us a surprising outcome. Let us know.
  17. Yet Another Phytosaur Prep

    And the after on July 21 2019
  18. St. Leon IDs

    great finds
  19. Yet Another Phytosaur Prep

    Your wish is my command. This is the before on February 25 2019
  20. Bone? Or raw jet?

    Slag for me too
  21. I absolutely love seeing your post! Great report and great pictures! Just wish I was there with you in that rainstorm. And also, looking forward to seeing the big rock all prepped out. RB
  22. Thanks The light makes it more pronounced but it is very 3-d. I was wondering the same thing but as it turns out, no locking needed. RB
  23. Hadrosaur Humerus Repair/Prep

    Being in so many pieces, this also offers the opportunity to see inside the bone. And there are some quite nice breaks that show the internal structure. Interestingly, even though the bone is preserved nicely in 3D, much of the main part of the humerus has collapsed slightly. Even when put back together, there will be some shifts in bone that I won't be able to put back into it's original place. Some closeups that show the thick cortical bone wall that is mostly intact. This is followed by some intact spongy bone. But in the very core of the bone, the spongy bone has collapsed into a solid stony mush.
  24. Spinosaurus bones?

    I'm just curious as the limb bones in picture 2 and 3 look to have collapsed in and would seem to be somewhat hollow
