  1. Post Oak Creek, Texas Oyster

    What is this Cretaceous oyster that I found in Post Oak Creek in Sherman, Texas? Most oysters in the creek come from a yellowish calcite-cemented sandstone from the Arcadia Park Formation of the Eagle Ford Group. It is about 48mm in length.
  2. 1" x 3", top and side view. The back is unremarkable, but I can post more views if needed. Any help is much appreciated, as always.
  3. Cretaceous Eagle Ford fish material?

    Front, back, end views. Approx. 3" x 1.5" If fish, what part? I've never seen this before.
  4. Found in Collin County

    Took a quick walk up the accessible part of a creek not too far from where I live and happened across this nice little vert.
  5. The rock it's imbedded in is approx. 1" x 2". Cretaceous, Eagle Ford. It would be plausible to find one in this area, I'm just not 100% convinced and thought you guys might have an opinion. Thanks for any help.
  6. Any idea if this is bone or shell? What might this be? Any help is very much appreciated. About 3/4" square. Thanks!
  7. BIG Texas Shark tooth

    From the tip of the root ( seems it may be longer, going further in the rock ) to the tip of the crown is a little over 2 1/4 inches. Dallas County, Atco Formation What say the experts?
  8. Texas Eagle Ford Exogyra Fossil

    In early July 2016, I encountered a virtual self-guide field trip posted online by Pete R. Rose, PhD in February 2012. He describes an Eagle Ford (Kef) outcrop exposed in the parking lot of Barton Creek Mall in Austin, Texas. I went there to check it out. The USGS webviewer only designates the area as Georgetown-Del Rio. But, the U.T. Bureau of Economic Geology has an accurate Geologic Quadrangle Map #38 that shows this feature. But, it predates Barton Creek Mall which is not on the map. Interestingly, the Austin Chalk Atco Member caps the nearby hilltops, but it is heavily weathered to caliche and rusty ferrous minerals. Difficult to find fossils in the transition zone. The South Bosque member is clearly visible and underlain by the Bouldin Flags (BF) Member. The BF has much thicker flaggy beds than I usually see (up to one foot thick). In the lower part of the BF, I extracted this beautiful slab of what I think are Exogyra columbella levis (Meek). The largest ones are ~1" wide. Most of the Kef outcrops I have visited have just fragmented oyster hash. This is the first time, I have seen the complete fossils rather than just rounded fragments. Also, I think a nearby rock had traces of a fish fin on it. I took a picture just after dark, but left the fossil there. It was a very large rock and a paper-thin fossil remnant. I believe it was about 6 to 8" long. Anyone have better IDs? I was surprised to see Exogyra in the Kef. Lee Schnelle
  9. Texas Cretaceous Shark Tooth ID

    Found this shark tooth in the Atco Formation, what's the species?
  10. I've been very busy lately but I did enjoy finding this nice Cretodus tooth hiding under a rock. Have a great weekend 😀
  11. Went out again this morning. Decent day with some good variety. Finds include mosasaur, shark, and fish. All from the Eagle Ford Group of far north TX. Late Cretaceous. 85-92 mya. First was a mosasaur jaw fragment
  12. North Texas got hit with 2+ inch hail yesterday. Luckily my house was sparred but I did hit a creek in the path of that storm. Found a few things including a large chunk of bone, few fish verts, possible plesiosaur tooth?, and some shark teeth. Eagle ford float material 85-90 mya. Video of the storm: https://m.youtube.com/watch?v=kMveT5HqmMw
  13. Big ole bone- north Texas ?

    Found this guy today. It was float material in a creek with eagle ford exposure. Much bigger than anything I've found in this area. Maybe a huge vertebra or pelvic piece? Somebody please say Dino ; )
  14. Decent week, found quite a few bone bits, a couple fish centra, and a tiny artifact..
  15. Kinda cool- I found these 2 fragments around 1,000 feet apart in a creek. I just discovered they match up. I assume this is a jaw fragment with a tooth socket exposed? Can we tell if it's mosasaur or bony fish? From eagle ford group of late cretaceous. Thanks!
  16. 9 more inches of rain last week so I'm hoping I'll do well the next few weeks. Here a few items found recently. Got a nice Gary point, a ptychodus atcoensis, articulated fish centra, and some mosasaur parts..
  17. After a trace of rain in 3 months, Dallas was treated to 10+ inches in 12 days. Had a fun week searching and found a pretty good variety. Got some cool Native American artifacts as well. We'll see what next week brings with some lower water levels.
  18. We finally got rain here after 2 months of nothing. Found a shark centra, a ptychodus mortoni, a large ptychodus whipplei, a few other shark teeth, and a Native American dart point dated Late Archaic 2,000-500 B.C.
  19. For once I remembered to take a pic before reaching down to grab my find! I love at looking at the in situ photos here in the Forum, it is almost as being there in person, so here is one for you Granted, this is an easy one. North Texas - Eagle Ford
  20. Hi, help with this bone would be appreciated. Hoping to pinpoint the ID so I can label it in my showcase. Found in North Tx, Eagle Ford, Upper Cretaceous. Density strongly suggests marine... Thank you, Suvi
  21. Found a few decent things this morning around Dallas. We've had a trace of rain in 45 days so it's been slow. Got a mosasaur jaw fragment, articulated fish vertebrae in matrix, and a prehistoric arrowhead from 700-1200 A.D.
  22. Found this odd claw-like bit today while sorting through gravel from Post Oak Creek. Any ideas as to what this might be? Scale is in mm. Dark photo just to show scale. Both sides of the object. The best shot I could get of the "proximal" end of the thing.
  23. Post Oak Creek Finds

    Found these in the Post Oak Creek in Sherman, TX. Eagle Ford and Austin Chaulk contact. Need help with ID ing these items. Thanks in advance for your help.
