  1. Ostrea quadriplicata

    Upper valve only.
  2. Going back several decades I have attempted to have an annual extended field trip; call it a fossil collecting vacation. Some years this happens, some it doesn't but this past November I had the opportunity to spend several days in the field visiting some of the classic Cretaceous and Paleogene river sites which abound in Alabama. Since I haven't had the opportunity to post much in my blog, I decided to post pictures from that trip here as I have time. First up are pictures from the lowermost Maastrichtian (~70 mya) Upper Cretaceous Bluffport Marl Member of the Demopolis Formation. The Demopolis Formation for the most part is a Campanian aged chalk however the Bluffport Marl Member which defines the upper portion of the Demopolis is a molluscan rich sandy lime lying within the Exogyra cancellata zone. Aragonitic shells have not been preserved however calcitic oysters are abundant including Exogyra cancellata, Pyncodonte convexa, and Paranomia scabra. Rarer elements include Exogyra costata and iron/hematite(?) pseudomorphs of Trigonia sp. Temperatures were near perfect in the lower 60s and when not collecting it was a joy to watch the ever present barges on their way to Mobile.
  3. It has been a couple years since I made time to pull together some photos of personal finds to share. Inhospitable climes this past weekend afforded me the opportunity to organize a little eye candy for your viewing pleasure, arranged from geologically oldest to youngest. Provenance - for brevity, I'll just refer to the sites collectively as "Gulf of Mexico Watershed, Texas". Thanks for understanding and respecting. For more detail, go to Youtube and pull up Johnny Cash's "I've Been Everywhere". I will say that the Texas Outback comes with its perils, as shown below. Some of the pics are grainy due to fleeting photo opps, but you can see a big gator sliding into the water, a curious tarantula, a snake (water mocassin?) exercising the "stand your ground" law, and a rattler that became tablefare at the Woehrhaus. I even had a "Hugh Glass" moment with an injured hog while out solo gigging this year, and was glad to come out on top. I should be able to complete photo adds to this thread today in short bursts.
  4. Look what I found! Yeah, I know it's been a while. My nursing career really ate up my life, especially being Director of Nursing at a long term care facility. So I took a step back and took things in another direction in regards to nursing and now I have Mon- Fri off to hunt! Woohooo!!! So today I hit a little spot on private land in E Texas and I found some great belemnites. Which are pretty fantastic for being in Texas.
  5. Please help identify. The teeth shown in the pictures were recently found at the W.M. Browning Cretaceous Fossil Park in Frankstown, MS. Oddly enough, they were found within about 15 minutes of each other in the same area. Each tooth is about 1/2 inches from tip to base and they all have the middle indentation in the base. In the photo of four, the left most tooth has the lines running through it, while the middle two appear to be more smooth and without any features. The tooth shown on the right appear to be more of a rock until I noticed it had the same indention in the base. Any insight would be most appreciated. Thanks
  6. well the collection is growing as picture along with a few nice teeth added to the picture are a couple questions...........
  7. Do I have anything here? I found these two after a good rain at the bend of a creek here in Austin, Texas. They are both around a 1/2 to 1" in length.
  8. New to the hobby but def hooked! Started off while I was tdy to Charleston and I admit that I have been spoiled by that but I'm not discouraged. Spent a few hours at big brook and shark river over the last few days. It was slim pickings but better than striking out. Would love to meet up with people.
  9. I usually find my own belemnites but I couldn't resist buying this one that's been attacked by the endolithic sponge Entobia. Belemnitella, maybe B. lanceolata (haven't checked it yet), from the Lower Maastrichtian Chalk of Denmark.
  10. Picked this up on a river bar north coast California. I read the rocks were formed during the tertiary, Cretaceous, and Jurassic time periods, hope that's useful information. I'll attach a couple more pics
  11. Could anyone recommend a reputable supplier of Cretaceous amber? thanks!
  12. My specimens of this species are 2-3mm in diameter, and the thickness in the center is about 2/3 of the diameter. Thickness on the edge goes down to about 0.1mm. .
  13. I think this is a skull fragment, but I cannot figure out from what. Found in the North Sulphur River near Ladonia, Texas. Found in a pile of gravel and rocks in the center of the river bed. No other associated bones were found. I labeled the photos Back, Front, Top, Bottom (Because thats what they look like to me). Any help identifying it is greatly appreciated. Back View. Front View Bottom View. Top View.
  14. I found this piece near Chloride, Arizona also visited the ghost town pretty awesome it weighs a little over 1.5 lbs about 4"long x 3"wide thanks for looking appreciate the help Dean Sr.⚒ here are some pics more to follow
  15. well I stopped by the brook before the snow storm comes and found some shark teeth and also found these if anyone could help out with id please....thanks!!
  16. just a few items that I wasn't sure of,if anyone can help,may be nothing....
  17. I found this tooth a few years ago in Northeast Mississippi. It is most likely from the Demopolis Formation, which is a late Cretaceous marine lag deposit. I have found several mosasaur teeth here, thousands of shark and fish teeth, and 2 hadrosaur dino teeth. This particular tooth is almost 1.5cm in length, and is unfortunately split right down the middle of the tooth. The part of both sides that is remaining near the tooth makes it look like this was a skinny tooth, more like the shape of a theropod tooth, similar to Dryptosaurus. The recurve is also more theropod-like. The color and weathering is also similar to mosasaur teeth that I have found though, and I am just unsure of what to think about it. Theropod teeth have been found in this area, but they are incredibly rare, whereas, I have found several mosasaur teeth. Perhaps the cross-section of the break along the tooth might give a clue? Perhaps @Troodon knows. I am currently leanung towards it being a strange mosasaur tooth, but I would like other opinions. Northeast Mississippi Demopolis Formation Late Creataceous ~ 72 MYA This photo has a pencil tip for size reference.

  21. any help please.....I'm hoping its a worn partial croc or mosasaur tooth,but what do you guys think...
  22. Hi, Wanted to confirm my suspicions that this is a Hoploparia Gabbi (arm/claw) in matrix. (approx 2") There also seems to be other parts of same among the included matrix. Thanks.
  23. irregular echinoid

    This is the second of this species I have added in Collections; to illustrate how variable their physical appearance can be. Hence, variabilis.
  24. Okay, here's a stumped for the detail-oriented. The first picture is Ostrea falcata, one of the more common finds in the Mount Laurel Formation. It is curved like a hook, with ruffles radiating out from the hinge. The second one is O. panda. (same size, left out the penny.) It's more or less circular, with ruffles only at the edgesThe other two are from the same spot at the same site, on the same day, but are clearly not the same species. The third one is rather fan-shaped. the fourth has a depression dividing the raised center from the the ruffled edge. I can't find them in my DE or NJ field guides. Web search turned up nothing. Anyone recognize them?
  25. irregular echinoid

    S. variabilis is an uncommon echinoid find in North Carolina. At present, to my knowledge there are 2 locations where it can be found. It occurs is the youngest part of the PeeDee. Most of the specimens are crushed or broken, which makes this one special as it is my only complete specimen. Variabilis is a good species name for this, I will be posting 2 others so you can see how variable they can be.
