  1. 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!
  2. 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
  3. 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?
  4. Glen Rose Micro-zone

    After a brutally hot and rather dry June we started July with some good rain. Tropical disturbance up off the gulf dumped a few inches over a few days. Just what we needed to expose fresh material. One particular spot, well known to some of the locals, exposes a layer in the Glen Rose Formation (Albian, Lower Cretaceous) that has been dubbed the "micro-zone". Technically it is the lower meter of Unit 2, Lower Member, Glen Rose Formation. It is known for rare and generally tiny echinoids as well as other GR fauna. Collecting anything other than the odd large oyster or steinkern requires crawling around with your face inches from the clay. When I got there it was hot. 98+ degrees and pretty much full sun. So let's just say I didn't stay too long. The rains had already fallen a few days before so I wasn't surprised to see footprints where someone had searched out the more obvious spots while it was still mucky. So I concentrated on when of the "corners" of the site that has produced in the past but requires a bit more effort. Although nothing I found was spectacular with the exception of one really good specimen of Goniopygus sp. (Rader & Smith) it did produce a handful of things I was very happy to add to the collection. First here is the Goniopygus sp. Rader & Smith (2009) did not assign these to a species as they are small and immature (goniopores are not developed). This one at about 7mm is on the large side. My others from here are 2-3mm in dia. Next is Hyposalenia phillipsae (Whitney & Kellum) and a fairly large one at that. And here is one of the most common GR echinoids you can find, Heteraster obliquatus. But at this site they are always exploded into hundreds of shards.
  5. Thoughts on this Tyrannosaur tooth for sale from the Aguja Formation of Texas. 2" Seller indicates some resto has been done to the tip to make it complete.
  6. I recently went on a collecting trip ending in the Triassic of New Mexico. I collected in four states and covered 6 geologic time periods. I have a number of trip reports to do, and I usually like to have everything identified before I post. However, I am waiting on some brachiopod identification resources (productids), and I want to get this out while I have time (more reports coming as I work on the specimens from each site). This report is on the Mineral Wells Fossil Park. It was four hours out of my way, but I was determined to get there on this trip (my first to the site) and managed to get in two hours of collecting. This is a great site, and kudos (and THANKS) to the Dallas Palaeontological Society, Mineral Wells Parks and Recreation Department and all others who helped make this great park possible.
  7. I got myself a bag of Aguja formation matrix a while back. I have been looking at it and wanting so badly to go through it, but I lack the proper sieves. Anyway, I got too curious a few days ago and used some metal mesh from a reusable coffee filter to filter about a cup of matrix down. To be honest, none of my equipment is up to par, but I’ve started a look through and it’s already fun! Will be continuing this thread till I get done with the bag, which may take a while. Updates will be periodic and this thread is mainly so I can store my information and share it but feel free to comment, help ID, give tips, follow along, or whatever you would like to do! Here it goes: Fishy Vertebra, very similar to my Miocene ones!
  8. Crinoid material?

    These tiny fossils all have a groove along the long axis. The surface is textured, but not reminiscent of bryozoan zooecia. Are these perhaps crinoid pinnules? Mineral Wells fossil Park, Keechi Creek Shale, Mineral Wells Fm., Late Pennsylvanian (Missourian). Scale in mm.
  9. Tooth or a Bone?

    Any ideas what I have here?
  10. Last time in Ladonia

    Last time in Ladonia Fossil Park.
  11. Anyone seen this before?

  12. Question about Mineral Wells

    What is the consensus on the name of the formation exposed at Mineral Wells Fossil Park? I've seen both Keechi Creek Shale of the Mineral Wells Formation, Strawn Group, Missouri Series (Pennsylvanian Period) and I've seen Salesville Shale, Desmoinesian. Does anyone have a citation for a peer-reviewed paper that provides empirical data supporting the formation name given and correlating it with other exposures?
  13. Short visit to Ladonia Fossil Park

    I spent less than an hour because it was to hot but I found the pice of vaculite and a small piece of bone.
  14. Fun morning hunt at NSR. Pretty good sized shark tooth for NSR.
  15. Prionocyclus bosquensis

    From the album Prionocyclus bosquensis

    Found in the Cretaceous Arcadia Park Formation from the TXI Quarry in Midlothian, Texas. It is Prionocyclus bosquensis according to Jim Kennedy, Professor Emeritus of Natural History at Oxford. He also first described the species. See his paper describing this and other species: Kennedy, W. J. 1988. Late Cenomanian and Turonian ammonite faunas from northeast and central Texas. Palaeontological Association, Special Papers in Paleontology, 39: 131 pp.
  16. Need help IDing NSR finds!

    I'm new to the site and have several interesting finds that are needing some identification! Me and my 8 and 9 year old boys have been digging away and are all very interested in knowing what we have. Google just isn't doing it lol! Any help would be greatly appreciated!
  17. T-Rex Tooth?!?

    Okay guys! I've been talking my little boys fossil hunting at Post Oak Creek in Sherman since they let out of school for summer. Trying to get them interested in it and FINALLY!!! My 8 year old(least interested) found this. Please tell me this is a t-Rex tooth!! We are all pretty stoked regardless but would love some insight. Thanks!
  18. I saw the first opportunity to get back to the North Sulphur River yesterday when the temps were going to be below normal for a change. There was a really nice breeze blowing down the river. Went to a spot on the river that I have only been to once before and access is pretty poor. Thanks to whomever added the rope, it helped, especially getting out! Quantity of the finds were low but the quality of what I found was great. Found the largest Tylosaurus tooth I have ever found with a diameter just under an inch. Also a shark tooth and one nice mosasaur vertebrae. I always enjoy the chance to find an artifact, ever though they are rare, or at least for me they are? I liked the way that JarrodB displayed his artifact recently, so I photographed this one the same and it turned out pretty good. Not sure the type, could be a Marshall, usually I find Gary's, so this was a nice departure. I will be watching for another cooler than normal Texas summer day to get back to this spot.
  19. I only had a couple of hours so I stayed right below the creek bridge. I had a couple of cool finds.
  20. Goblin or something else?

    Found this tooth at Waco site. Del Rio formation, Albian.
  21. Spoils from a Spousal Sortie

    Best of our tag team take of Walnut fm echinoids from a recent trip.
  22. Howdy! Not long ago I acquired this nice 11-inch ammonite from Texas. Per seller this was collected at a quarry in Crawford- a fast glance at maps show a variety of formations in the area including Edwards group formations. From the best of my knowledge this ammo is a species of Oxytropidoceras genus and a nice-sized one. Anyway... the question of this thread: Within the inner whorl is a collection of shelly material. When I purchased the piece I assumed it all to be indistinct shelly debris but in hand it appears more distinct in form and perhaps identifiable. I have my own guess to what it is, but I thought I'd have the many Texas-based collectors here at TFF have a look at it first, if it's not too rude to ask. Can the inner material be identified? Thanks in advance!
