  1. Grayson Formation ID urchin spine?

    Echinoid urchin spine is a complete guess. I don’t have a clue. Does anyone know what the tan thing with bumps is? It is just over 2 cm long so far. I found it in the Cretaceous, Grayson Formation in North Texas. It has Mariella brazoensis, Waconela wacoensis, a little nautilus, way too many oysters among other things in the conglomerate with it. Could it be an urchin spine? It has tiny, basically microscopic bumps all over it too. It still needs work uncovering. I came to the oyster on top of it and will have to take another approach to removing the oyster.
  2. Here’s a small group of items I found in the North Sulfur River (Ladonia, Texas) over the weekend. I’m curious if A,B and C are coprolite? I’m wondering what species the shark tooth is as well. Thank you in advance!
  3. Good time at the North Sulphur River in Ladonia, Texas this weekend. Here are some of the things we found! I’m curious about the gray ammonite (bottom right). I’ve attached a few photos at the end (first two photos) to see if any of you know what the black line is running through it at the bottom. It reminds me of the vein in a shrimp!
  4. FOSSIL ID - large animal Vertebra?

    My husband and Daughter found this piece along the banks of the Brazos River in Sugar Land (south West Houston) we have no idea if it’s fossil or just bone. Or what animal it came from - any help appreciated
  5. Fossilized bone section

    I was in a stream bed near Killeen tx today when I found this. I thought it was a bone fragment from recent origins until i picked it up. When I did I found it was clearly fossilized. What the heck did I find?
  6. Fossil help

    Hello! Can anyone help me identify if this is a fossil? Thank you!
  7. Our second summer trip was up to the Glen Rose, TX area. We rented a great place via Home Away that had a fossil hunting spot. Super convenient when the heat was >110F. We hit the Dinosaur Valley State Park and went fossil hunting at the property we stayed at. Found lots of great cretaceous fossils. Still trying to identify a bunch of them. We found heart urchins, devil's toenails, I think there are some Oxytropidoceras fragments, etc. Oxytropidoceras fragments? Not sure what this is yet.
  8. First time posting. Let's do this... We went fossil hunting with our two boys: 11 and 13. We had a blast and collected a lot of interesting fossils from the Eocene (Stone City and Cook Mountain formations). So many fossils! Lots of little things to sift through. We didn't find any shark teeth, but another person did and showed the boys to inspire them to keep looking.
  9. Between honeydos this weekend, the Cenomanian Crevasse sang its siren’s song again, tickling my ears, and I was helpless to the call. I will take my buddies with me soon, but the 30 minutes spent solo on site this weekend were pure bliss. On gloves and kneepads I navigated the hummocky surface of the Mainstreet limestone, tapping the pregnant humps with my hand sledge, listening for hollow thuds, and flipping some easy splits. Neithea scallops and Waconella brachiopods were only outnumbered by Ilymayogyra oysters. But I was after a few things a bit less common. One fortuitous blind flip triggered a spontaneous “Tim the Tool Man” chortle as I spotted 2 big whorls of a Mariella ammonite, with perhaps a third diving into the rock. Prep will tell. But this was just a warmup.
  10. South Texas Siphuncleage

    I found a couple ammonites this summer that needed very little prep. The first is a Pecan Gap fm Pachydiscus travisi, not remarkable for quality of preservation, but rather for presentation. With both impressions and the steinkern found eroded out together, I have “all the pages of the book”, something that doesn’t present often, in my experience.
  11. Navasota what the heck?

    So i stop by the Brazos in Navasota and find calcite reminiscent of rucks pit- And this....
  12. Currently in Bryan Tx

    Hey y’all!!!! Currently in Bryan tx looking to hunt the brazos tomorrow! Anyone have tips or hints? I’ve heard the whiskey river is pretty good, I’m focusing on sharks teeth myself.
  13. Morning Northeast Texas creek hunt.
  14. Collecting on the Sly

    So my wife asked me to round her up some free landscaping rocks today, which I did, but I left the times of coming and going a bit fuzzy so as to afford myself a look at a small, slowly eroding exposure of Georgetown limestone that I found about 15 years ago, and have kept more or less under my hat ever since in order to allow adequate weathering between visits. The bedrock is mostly covered with gravel these days, but the hummocky suface poked through in a few spots, bringing a couple 2 inch Coenholectypus echinoids to hand while doing a surface crawl. Blind mining revealed a few Mariella ammonites as well, all a whorl or 2 shy of keeper status. The beating sun and resulting sweaty brow prompted me to pack it in after 30 minutes or so, but a funny spalling precipice of limestone caught my eye and beckoned a quick whack with the chisel and hand sledge...revealing part of the adult whorl of a hopefully intact Graysonites ammonite, rare in the San Antonio area. 10 more minutes of careful chiseling ensued, going at it lightly from all sides till it popped out in 1 piece! Preservation of steinkerns at this site is not as crisp as in far North Texas, but home town pride makes up for that. Many ammonites into this pursuit, I’m happy to report that blind serendipity can still steal my breath away and leave me thankful to experience the joys that nature can present. Next round, I’ll take a tenured buddy or 2 for the harvest. A little blind sweat equity should prove fortuitous for each of us, give a couple hours of steel driving.
  15. Eagle Ford Fish Fossils

    Here are some of my fish fossils from the Eagle Ford group of North Texas. Apsopelix sp.
  16. Hi all! I was down in the North Sulphur River bottom (Ladonia, Texas) this evening and found this small, but nice tooth. Any ideas what this tooth may have belonged to? I found a few other nice picks that I’ll post later, but I was eager to learn about this one. Any help would be appreciated.
  17. Coprolite? Botryoidal?

    Is this Coprolite, Botryoidal or something else? My first initial guess was Coprolite but endless google searches have me second guessing. Found all three in the river bed on North Sulphur River.
  18. I found this a few years ago and it continues to fascinate me. Occasionally my mind wants me to call it Dino but I’m pretty certain this belongs to a Plesiosaur. 9 inches long and weighs almost 10 lbs. North Central TX Late Cretaceous 86-92 mya
  19. Fossil Fish?

    Is this a fossilized fish? Found in North sulphur River in TX.
  20. Bone! What is it?

    My recent find! Anyway to identify this? I have tons of bone pieces but nothing like color or sheen of this! Found in North Sulphur River in Texas.
  21. Ereotherium caudal??

    This is a vertebra that I found on a gravel bar last month on the south Brazos. It is large but has a small neural opening, and I wonder if it is from near the end of the tail. Someone have a clue? It does look like a megatherium caudal that I found in a paper, but that photo is poor.
  22. There are a number of Kritosaurus teeth, from the Aguja formation of Texas, being sold online. Question are they identified properly? Thank you Two examples
  23. Hello all! Sunday on the North Sulphur River in Ladonia, Texas was hot and dry, but still a great day!!! Friends found some beautiful arrowheads and shark teeth! Here are a few things from my trip! I believe I have here a piece of mastodon/mammoth tooth enamel, shark tooth?, bone chunks (not sure from what), a piece of flint??? Any ideas of the specifics? Thanks in advance!
  24. The Aguja micro vertebrate assembladge is quite diverse. I've attached a few of my finds some identified some misidentified , some unknown . Lots still to identify and photograph so I will keep adding to this topic. Apologize for the quality of photos need to invest in a better digital scope to obtain crisper photos of these tiny specimens. Material is Campanian in age from Texas Dinosaurian Actinopterygii Additional Teeth Amiid Fish Tooth Below, Lepisosteid Tooth Top Chondrichthyes
  25. Teeth from Aguja formation

    I obtained some matrix from the Aguja formation, which is late Cretaceous, from Brewster, County, Texas. I have been finding all kinds of good stuff, but will start with the following. The first two pics are from what I believe to be a therapod - maybe Tyranasaurid? There are approx. 5 serrations per mm. The next two are of an unidentified tooth. The last is a group photo of what may be Champsosaurus teeth? The hash marks are 1mm. Any ideas?
