  2. Unidentified small radiating shape

    Hi Franz, That was really quick!! And thank you so much for pointing me in the right direction. Truly appreciated! I googled the geological map of UAE and it turns out Jebel Hafeet lies in the Maastrichtian age (late Cretaceous). Thank you again! Mohammed
  3. Help with some Mazon Creek fossils

    How are they kept?
  4. Petrified wood but what else?

    Don´t worry, if things get worse or not! There seem to be somewhat repeating collapse(??) patterns, don´t know, if this means something... Sorry, I can not really help, but its a very interesting specimen. Lets see, what other members have to say! Franz Bernhard
  5. Unidentified small radiating shape

    Welcome to TFF from Austria! These are very well preserved cross sections of scleractinian corals. Nice!! I think you can google up geological maps of UAE, then you would be able to put an approximate age to this specimen. You will find also the formation name on this map. With this formation name, you might be able to google up the fauna of this formation. Maybe you can find something similar already published in a paper! Franz Bernhard
  6. Petrified wood but what else?

    Not sure if this helps or makes things worse, but this is the other side. It has more of the collapsed holes.
  7. Unidentified small radiating shape

    Hello all, Im new to this forum and new to fossil collecting. I major in biology and come from collecting numismatics for several years. I’ve found something very unique in paleontology, and that is immense age, which drew me to collecting fossils. The piece below was collected from Jebel Hafeet in Al-Ain, United Arab Emirates (quite high up the mountain). I’ve noticed two odd, radiating shapes (just below the mid-area of the rock). It’s about 10-15 mm in diameter. I’m not an expert in fossils but thought it looks too orderly to be classified as inorganic. Any advice would be greatly appreciated. Best wishes, Mohammed
  8. November 2019 - Finds of the Month Entries

    Nice matrix specimen, thanks for entering! Would you like to provide some background info, e.g. about your collecting trip to this area? And whats the size of the specimen/fossils? Thank you! And the same here: Very nice specimen! But I have never heard of this formation (but this is just me ). Would you also like to provide some background info? Thanks so much! Franz Bernhard
  9. Petrified wood but what else?

    Welcome to TFF from Austria, @Coastalrocker! Nice contrasting opinions! The layering of the matrix looks woodish, but the "striation" seems to cross also the filling of the holes (only scratched surface?). The holes don´t have any septa nor can I see some costae (did I miss some?). Some of the holes are collapsed or displaced, I don´t know if this is typical for one or the other. In summary: I don´t know what this is! Franz Bernhard
  10. Petrified wood but what else?

    This is known as Teredo wood. An internet search will provide similar photos to your specimen. The "tubes" are boreings of of what was once thought to be a worm but is now known to be a marine clam. The crystal lining is common in many specimens.

  12. Sometimes You Have To Whack It !!

    Thanks Rich, I have been putting off opening concretions and need to get in gear. Can’t wait to see your finds.
  13. I have been negligent in posting specimens here lately. Here are some recent openings. Enjoy! Cheers, Rich I nice orbicular pinnule of Macroneuropteris. A syncarid shrimp. I can't see the tail to probably either Tyrannophontes or Acanthotelson. It looks much better in person! This one was a small chip off a much bigger concretion. It pays to be patient with the river concretions as individual layers can contain a fossil. And a millipede. It's small so the quality of the picture isn't great. I'll try to take a better one with my USB microscope.
  14. Turtle flipper?

    A turtle's flipper would have bones similar to our hands ( but a little different of course! ) Here is a picture of a sea turtles "flipper" bones.
  15. Trilobite cemetery?

    Sorry, I do not.

  16. Sometimes You Have To Whack It !!

    Great to see you back at it! And, some real nice shapes to freeze/thaw... Good Luck! The new specimens are exciting as usual. I'm going to post a few recent openings in my river post as I have been neglecting lately too! Cheers, Rich
  17. Dug this little guy out today from same deposit as Sharktooth Hill location ( Mid. Miocene ). What I would like to know is this from a juvenile or a small posterior adult tooth. It is prepped labial side showing. Thanks for your insights.
  18. Head Scratcher

    Given the sharpness of root angle I would put it as a G. aduncus.
  19. Petrified wood but what else?

    Yes!! Thank you. After looking at pictures I’m fairly certain it is. Googling “petrified wood with tubes” was definitely not helping me out. New to fossils and rock hounding (mostly agate hunting) so I’m sure I will have more questions! I appreciate the help!
  20. Let's see your latest mailbox score!

    I am guessing it may be from Michigan but it came with no label and the seller didn't know much about any of the fossils he had.
  21. Unique Mazon Creek

    Those are really nice! I really need to go there!
  22. Trilobite cemetery?

    Nor did I! Please show pics if you've got any, grandpa.
  23. Let's see your latest mailbox score!

    Nice batch of acquisitions... I've got a Utah Cambrian brach and of course the Ellipsocephalus, but still need to get me one of those St. Petersburg trilo and a cystoid. I've seen them around but haven't managed to pull the trigger yet. Any idea where the Hexagonaria is from?
  24. Shark tooth ID from Jacksonville, Florida

  26. Multiple Hunts this week

    First rate report, Jack! Thanks for posting your wonderful pictures and finds.
  27. Petrified wood but what else?

    A phaceloid coral colony, i should think. Something along the lines of Siphonodendron perhaps.
