    I agree with Dipleura dekayi. Don
  3. Show us your rarest sharks tooth

    Heptranchias is most definitely a scarce genus in the fossil record, awesome tooth!
  4. 2020 Secret Santa Extravaganza.

    I am sorry that I have not have a chance to post the pictures earlier. Here are the fossils I got from my secret Santa. Most of the fossils are self collected from Puerto Rico, some is from UK and some shark teeth which are not self collected. I think I know who my secret Santa is.

  7. Unidentified Brachiopods

    Productus magnus is quite common at the site and I collected several nice pedicle valves. Weller's "The Mississippian Brachiopoda of the Mississippi Valley Basin" was used to identify most of the brachiopods but there wasn't a brachial valve in the plates. As always, thanks for the help!
  8. Great Day at Matoaka

    Beautiful weather, beautiful site, beautiful finds. Just about all one could wish for. Thanks for sharing.
  9. Catskill Formation, Pennsylvania 2

    Great pictures, thanks for posting There are two recent papers about the taphonomy, sedimentology, and paleogeography of these deposits. they are: Broussard, D.R., Treaster, C.J., Trop, J.M., Daeschler, E.B., Zippi, P.A., Vrazo, M.B. and Rygel, M.C., 2020.

  10. Strange fossil, Bug? Plant?

    Looks like radial symmetry to me which generally screams plant. However a close up of that recessed section in mid lower left looks like segments to me. Possible to get a clearer shot of that spot?
  11. Show us your rarest sharks tooth

    Upper and lower Heptranchias from the Oligocene of Poland. I think it is a rare enough genus to warrant inclusion here.
  12. Unidentified Brachiopods

    The first on is screaming 'spiriferid' at me, but it might be Productus magnus, I'm really uncertain. Interesting. The next one looks like Buxtonia. I'm going with Atryparia for the last one.
  13. Show us your rarest sharks tooth

    Great tooth and I would agree super rare if you have the only one !
  14. Fossil Lycophytes from Texas

    I dont know what it is--I am curious about the lycophyte guess and its basis...As Rockwood suggests it could be geologic but the one side does also seem to have an odd badly preserved palm/cycadioid trunk fragment look to it. Has any other plant material been found in the area? There appears to be some interesting very fine laminations/layering in the one area that I highlited with the red arrow that may or may not hold a clue. Hoping some of the Texas folks will chime in with some local knowledge. Interesting find! Regards, Chris
