  1. ThePhysicist

    Cretolamna sp. Shark Teeth

    From the album: Post Oak Creek

    Cretolamna teeth from POC. The largest one seems to be the C. dwardius as described in Welton and Farish's guide, the others are C. appendiculata.

    Maybe its a pearl?

    I think it is a fossil pearl. It was found in a shell fragment in Post-Oak Creek texas, but I am not sure as it is the first I have found. If it is a fossil pearl how do fossil pearls relate to common pearls
  3. Woodgrainstone

    Unknown Cretaceous Ammonite Texas

    Recently cleaned up an Ammonite. From the Albian or Cenomanian (?) Series, Boracho Formation, Culberson County, Texas. I don't have much experience with Ammonites. The HGMS Ammonite book I own is not as helpful as I had hoped. Thank you 11cm across, 9cm tall, less than 2cm thick
  4. I found theses fossils 20 years ago or so, while visiting My Very Good Friends (and former house mates) in San Antonio Texas. I had brought a flyrod on the trip as I knew there were some creeks near their house and I wanted to spend sometime fishing them. One afternoon I grabbed my flyrod and a box of Wooly Buggers and walked the 3/4 of a mile to the nearest creek. as I was rigging the rod I started noticing the Devil's Toe Nails laying along the banks of the creek. I began picking them up as they looked pretty cool and I knew what their common name was. Fishing was pretty good as I caught a number of small Bass and a few species of Sunfish on the flies. I kept picking up the Toe Nails as I fished and soon had my pockets filled up with them. I stopped picking them up, but kept fishing for a few hours. returning to my friends' house I washed them off and dried them off on paper towels. they looked really nice after washing them of the dirt. I knew they were of Cretaceous age and I knew they are called 'Devil's Toe Nails" but I have never learned more about them. If anyone can Identify them for me that would be soo appreciated. Thanks for any help!, Dean ~~~

    8/16/20 Trip

    From the album: Post Oak Creek

    Didn't find much this time. I don't think it's rained in a while - the water looked stagnant. Also was picked over well. Favorite find is the mostly complete Cretodus (found it under a fallen tree).
  6. ThePhysicist

    Sawfish Oral Teeth

    From the album: Post Oak Creek

    Tiny sawfish oral teeth can be found in POC by simply taking some gravel home to look through under a magnifying glass, or a microscope if you've got one.
  7. ThePhysicist

    Hybodus sp. Shark Teeth

    From the album: Post Oak Creek

    Small hybodont shark teeth from the Late Cretaceous of Texas.
  8. ThePhysicist

    Mini mosasaur

    From the album: Post Oak Creek

    A fragment of a small mosasaur tooth.
  9. ThePhysicist

    Hybodont Shark Spine

    From the album: Post Oak Creek

    A first for me, I found the end of a hybodont shark spine.
  10. ThePhysicist

    12/31/19 Trip Haul

    From the album: Post Oak Creek

    Made one last trip to POC before the year's end and found some neat things, as always.
  11. ThePhysicist

    Cretoxyrhina sp. Shark Teeth

    From the album: Post Oak Creek

    Another one of my favorites, the "ginsu" shark, so named for its sharp blade-like teeth. The largest one in the center is indeed from POC, but I bought it online.
  12. ThePhysicist

    Ptychodus sp. Shark Teeth

    From the album: Post Oak Creek

    One of my favorite teeth to find, Ptychodus was a large shark that likely feed on hard-bodied animals like shells, crustaceans, or maybe ammonites. Most of the teeth here are from P. whipplei but there are a couple that could be P. anonymus.
  13. ThePhysicist

    Cretodus sp. Shark Teeth

    From the album: Post Oak Creek

    Some of the largest Cretaceous shark teeth you can find are from this genus. These are most likely C. crassidens.
  14. ThePhysicist

    Squalicorax sp. Shark Teeth

    From the album: Post Oak Creek

    Typical crow shark teeth from POC.
  15. LBI


    Found this yesterday in Medina County, Texas. Any help is much appreciated. Part of a crab claw or leg are my thoughts, but couldn’t find anything that matched.
  16. Texas Fossil Hound

    Good Day In The Tx Upper Cretaceous

    I went out with Creekcrawler to check out some areas of the Upper Cretaceous last week and had a pretty decent day despite the heat and the hogs Barry decided to spook. Nice Placenticeras Ammonite - (see the prep story in the Prep Forum of this site). Full Mosy tooth still embedded in the matrix. An unusual vertebra still in the matrix - possibly a ray vert(?) Several nice gastropods And a myriad of bits of Enchodus, Bison, Croc, Gary point, Serratolamna, Squalicorax, and Ischyrhiza. Happy hunting! Jon
