  8. Hey everyone! I thought I'd share a few of my finds from the past couple months and get yall's opinions. Over winter break, I went back home to North Texas and did some searching around Ammonite Beach at Texoma and the NSR with my family. At Texoma I had a nice time hammering out a few ammonites, collecting teeth, and surprisingly finding lots of smaller, pyritized ammonites that I did not expect to be there. The NSR was a bit slower, but I at least got a nice Squalicorax as shown in the pics below. Since school has started, I've been down in Austin. I've been finding the usual stuff, but the pyritized disk I've attached is new to me. I'd love to hear what you guys think! Austin Finds: Pictured above is the pyritized disk and a pyritized clam found in a gravel bar next to what I believe to be an Ozan exposure. The area has a decent amount of the pyritized clams and other marine fossils that I assume are cretaceous in age given the local geology. My initial reaction was that it could be a vertebrae, but the bulging center and distorted shape throws me off. It has very apparent concentric rings on both its faces. In pics 1 and 3, you can see that underneath that outside layer there is a lot of pyrite. Parts of the edges are also pyritized while other sections have an iron concretion look to them. The face shown on pic 2 resembles and feels like petrified wood. I suppose this could be a pyrite sun, but I'm not seeing anything too similar to what I have on google images. Super interested in what you guys have to say! Texoma Tooth (left) and NSR Tooth (right) Left (Leptostyrax macrorhiza?): Pretty tooth found by my little brother at Texoma in the Duck Creek Formation. Did some quick googling and found that Leptostyrax macrorhiza was in that formation and saw some pictures that were similar to what I have. Right (Squalicorax): Had a bit of a slow day at the NSR, but managed to at least find this at the end of my cold, muddy adventure there. It's preserved very nicely. Looks like Squalicorax to me. Would love to know the species. If you guys would like any additional closeup pics feel free to let me know! I might share some of my other finds later on, but I don't want to inundate the forum with my rocks lol. Thanks for reading.

    NSR Red Zone Ammonites ID Help

    A couple of weeks ago I made my first ever trip to the North Sulphur River "red zone." I had a blast collecting some of the ammonites there- and I thought I did pretty well- but boy is hiking through the river a lot of work. I was really happy to be able to find a nice variety of ammonites, including these two ammonites that I cannot quite seem to fit within the ammonite faunal lists I have seen for the Ozan Formation. I also found this tiny phosphate chunk in a concretion of the "red zone." I would normally say that it is a random chunk of phosphate, but I thought that the banding was unusual. I have no clue what it could be, if it is anything. #1- 3cm wide- what has me confused is the lack of any noticeable suture lines or ribbing #2- 1.5cm wide- the ribbing kinda reminds me of Scaphites sp. and there was a chunk of material that flaked off extending from the ammonite, but the "club-like" suture line has me a bit confused #3- 7mm tall- no clue what this could be

    A Physicist's Collection

    While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.

    Muddy riverbed

    From the album: North Sulphur River

    Made my first trip to NSR since construction began. There's a significant accumulation of mud, much less ground for hunting fossils.

    Small Mosasaur vertebra in situ

    From the album: North Sulphur River

    The only way I can find fossils - if they're right out in the open! This one conveniently perched itself on a rock.
  15. Hey everyone. First trade went well so I have another group to trade. I do have at least one more with a mosy tooth I will post either later today or sometime this week. Everything is unprepped except a toothbrush, water and elbow grease. Looking to trade for ammonites. Preferably complete specimens but willing to look at what you are willing to offer. Large Pholodomya lincemani, mini Pachydiscus (P.) paulsoni, urchins from Fort Worth (not NSR but figure I have 150+ of them), 4 mosy verts (mix size and condition. one with the enamel still affixed. species are hard to determine but someone might be able to identify), calcite covered Inoceramus barabini, Turitella trilara, baculite, and Tylosaurus proriger (one side shows great, other has damage as in the photo.

  18. Hi everyone! I'm a newer member to the fossil hunting community. I first started as a little kid, but have only really gotten into it over the pandemic as a hobby. I've done some hunting up around Dallas where I'm originally from, visiting famous spots like NSR and POC. For college, I'm currently living in Austin and have checked out a few nearby spots. These past few months I've been frequenting a local creek that runs through the Ozan layer and have been finding some cool fossils/artifacts. The items I am showing you today are collected from two places. The first assortment (lots 1 and 2) are from the NSR and contain Cretaceous/Pleistocene fossils. The second group (lots 3 and 4) was collected in Austin and contains Cretaceous fossils as well as some artifacts. For some objects, I am fairly certain of their identity, but for others I have no clue. Some fossils/artifacts have additional closeup shots for greater detail. Any comments or tidbits of wisdom concerning their identities or fossils in general would be greatly appreciated! Lot 1: NSR fossils I am fairly certain of 1A: Vertebra I believe to come from a mosasaur. 1B: My favorite piece from the NSR: A mosasaur tooth with a sizeable chunk of seems to be bone/root(?). It's a bit weathered, but there's still enough to get the imagination running! 1D: A nice little red bivalve from the red layer. 1E: A fragment of Pleistocene tooth I would love to know more about! From looking at the folds on it and doing some researching, I feel that it could be from a horse. 1G: The nicest piece of baculite I found that day. 1H: I'm not sure if this is a piece of coprolite or just a random cluster of two fossils. There is an identifiable baculite fragment and gastropod. Moving on to the second lot from the NSR, these are the things that I have very little notion concerning the identity of: 2A: Could just be an oddly shaped piece of sandstone (as it has that texture), but it does make me think of a scute. I would love to hear what y'all think! 2B: I truly have no idea what I am looking at. It feels like a fossilized "something", but that is all could really say. Here are some closer pics: 2C: Petrified wood? 2D: Very strange texture. My initial thoughts were some type of bone or petrified wood. 2E: Rock with fossilized bits of something that is difficult to identify. Maybe fish parts? 2F: A piece of cylindrical bone I believe. 2G: Piece of turtle? 2H: No clue. 2I: Petrified wood? Lot 3: Fossils from Austin Creek that cuts through Ozan layer 3A: Fairly certain this is an ammonite valve. Found quite a few in this creek for some reason. They never want to be whole. 3B: Good size vertebra likely from a mosasaur 3C: Really don't know what this is. My best guess is some really weathered down ammonite. It has symmetry and an overall spiral shape. It kind of reminds me of a curled up shrimp. Would love to know more about it! Here are some closeups: 3D: Nice little heart urchin. 3E: Nice urchin. I had only ever found heart urchins until this one, so it was an exciting find. 3F: Gastropod. 3G: Have yet to find a complete shark tooth from this spot, but here is a fragment. Might not be enough to secure an ID, but it's worth a try. 3H: Strange little fossil. Seems like some bryozoans grew on it at one point. When I look at it I get thoughts of echinoids and crinoids. Would be interested in hearing y'alls thoughts. Lot 4: Artifacts from the Austin creek (I know this isn't an arrowhead forum, but I figure there's a lot of overlap in hobbyists so there could be some insights): 4A: I believe this is a part of a larger tool like 4B. Not sure if these are knives, scrapers, or something else. 4B: Knife, scraper, or something else? 4C: My favorite artifact. Super pretty and thin. My guess is an atlatl dart point? 4E: another point, though not as visually appealing as 4D. The base looks a lot different too. Could this be an atlatl point? 4H: The base of some point. Would love to know more about the names or dates of any of these! If anyone would like more closeups of a specific item, feel free to let me know!
  19. All were found NSR today. I am really guessing on both. I am going turtle pleural bone just from the pictures I have seen. Other than a really small mosasaur I am clueless on the verts.
  20. I am new at fossil collecting. I found 2-3 of these. What are these? I've searched the forum and cannot find anything on this. sus tooth thingy1.jfif
  21. I had a scare last week that has made decide to stay away from the North Sulphur River feeder creeks for good. It all started when I decided to check out google maps to find a more remote access point since the river has become so picked over. I found a feeder creek that had a bridge that emptied into the NSR and decided to try it out. Well it took an hour just to get halfway all the while I was clomping though thick mud. I then turned a corner and came face to face with a 200 plus pound wild boar. I must have rustled it up from sleeping because it shot up once it saw me and started snorting. By this point I was stuck in the mud again, in the middle of the creek, but luckily it did not charge me. I franticly unstuck myself and backed away slowly and somehow climbed an almost vertical cliff wall. It is amazing what you can do if you have to. I observed the boar trying to climb out of the creek and luckily for me it was to the other side of the creek. I was amazed by how fast and how good at climbing it was even for its massive size. I walked the rest of the way to the river above the creek, looking back about every five seconds to make sure nothing was behind me. Once I made it to the river I made a decision to stay out of those feeder creeks for good. It wouldn't matter what I found in it because it wouldn't be worth going though that again so from now on ill just walk my way from one of the NSR access points. Not to mention all I found the entire two hours was a small broken shark tooth. However once I made it to the river I actually did find a couple of nice finds. I was excited to find my first ever mosasaur tooth in pictures 3 and 4. However it is a strange tan color and I really would have liked the nice shiny black that I see so much on here. I also found a piece of mosasaur jaw fragment in pictures 9 and 10 that might have actually housed the tooth I found earlier haha. In picture 5 I found a fully intact sawfish rostral tooth. And lastly in picture 22 I found a piece of Baculite that had some really nice preservation on it. The rest are items I'm not too sure about so please let me know if you see something in these pictures I wasn't able to identify. See below: Is picture 2 a shark or fish vert? Any idea what pictures 6, 7, and 8 are of? Picture 11 looks like it might be fish bones in coprolite or maybe matrix? Picture 12 is turtle maybe? Pictures 13 and 14 appear to be bone so maybe a part of mosasaur paddle? Pictures 15 and 16 are very similar to 13 and 14 however the fossilization is much newer so I am thinking Pliocene mammal? Picture 17 maybe fish jaw? Picture 18 and 19 also fish jaw? Picture 20 is not a fossil but maybe pyrite? And picture 21 is just a strange piece of mosasaur bone that has about 4 rounded cavities on it. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22.

    Ok..I have to ask...egg?

    Hi Everyone, I have had this piece for about a year now. Every now and then I pick it up and take another good look. I know it might not be an egg but I need to at least ask the question. If anything I can add it to my outside rock collection and be done with it. Found NSR, Delta County, TX. I have read the Egg topics here. There is still texture on the "shell" even with it being in the river rolling around. Thanks in advance for you time and knowledge.
