  1. Possible Vert, but from what

    North Sulphur River find from 5/27/18 Think it's a vertebra but it's not one I recognize, its 4.75 inches wide, 3.25 inches high. Pretty badly beat up from rolling around the river.
  2. I know very little on Pleistocene fossils but I always thought the horses that roamed during the Ice Age were much smaller than the modern ones. I found this large solid rock horse cannon bone fossil at the North Sulphur River Texas which is comparable in size to the modern day ones I find. I'm 100 % sure it's a fossil. Sorry I can't take measurements but I'm offshore working. Lol you can use my 6 yr old grandson for scale.
  3. What is this? (NSR)

    This is one I forgot about. It looks like bone to me but I could be wrong. Any thoughts?
  4. Plesiosaur Blues

    This is the result of two trips after some major rains. This was something I hoped to find, but have failed so far. I found a piece of jaw, so the thought of digging it is gone, but would still love to collect the rest. They are beautiful. On the first trip, I stumbled upon the first vert sitting high atop a shale pile calling my name. I admired it for a while and moved along happy with the find. On my way out, I caught a glimpse of another under water and that got me excited! I have spent a few trips just to look for it, but nothing until this past weekend. A couple more verts showed up. I know it can’t be far, but I think it stays under mounds of shale all the time.
  5. NSR post rain finds

    Well I almost don’t want to post after seeing some of the amazing finds posted from the NSR recently, but had what for me was one of my better trips. I don’t make it out there often but like many was lured by the recent rains and the hope of finding something great. I will say that I am always happy to get out on water and the weather could not be better than it was this week. I hiked a mile or so both ways and funny enough, as usual my best finds were found where everybody enters the river. I don’t know about the rest of you, but I play a game like a scavenger hunt every time I go. This trip I was after a vert, a mosasaur tooth, and an artifact. Nailed it. Funniest part is I was leaving and found the scraper less tha 25 yards from the stairs as I was leaving. I found a killer piece of P wood that has unreal colorations. Thanks for looking.
  6. I found this in the North Sulphur River in north Texas. I’ve had a few guesses on Facebook, but wanted to see what I can get from here. Thank you for the help. It’s about 2 1/2 inches long.
  7. Unidentified NSR Bone

    Found this today at the North sulphur. Any ideas what this is from?
  8. N. Sulphur River ID

    Found this interesting piece over the weekend in the North Sulphur River. What has me curious is the tube on what I’m calling ‘the back’ that has calcified. Any ideas on what it is and what it came from?
  9. NSR Binge

    Hi y’all, I’ve been hurting for some good fossil hunting since moving to Memphis and as luck would have it a job put me within 3 hours of NSR. Not to mention the water level reports from last week that I’ve been salivating over. So I hopped in the car and managed to get out and hunt last Friday, Saturday with 2 friends, and Monday.(Sunday I went to Post Oak due to weather lol). Water is still pretty high in most areas and some serious water hiking had to be done to get to the bars. I went in twice and my buddy went all the way in. Most areas where I hunted were undisturbed and fresh for the picking.
  10. Hello fellow creek crawlers and rock hounders! I am not dead LOL! After a 3 year hiatus I am happy to be back here on the first forum I have everjoined posting my secret guilty pleasures which are of course...fossils. Sothe reason I am back is I finally found a peer here in Texas who is aBiologist with a huge love for paleontology to go on trips with (rememberI'm from Indiana) and we have always wanted to go to the North SulphurRiver in the middle of Texas winter, arguably the best season for fossilinghere! No venomous snakes out and no bugs. So we made an impromptu trip from Princeton to Ladonia on the tenth becausemy friend and I were craving an adventure for a chance to find mosasaurbones. I was so surprised it now takes literally 1 hour to get there versusabout 8 years ago, when I first moved here, I swore google maps said ittook almost 3 hours! I was so happy to read that and we arrived there inwhat felt like only a 20 minute drive. No fast food places or Walmarts onthe way, just really old towns lost in time and country fields. Afteralmost a decade of wanting to see this place I finally saw the river! The stairs absolutely killed me, let me tell ya! I'm in my late 20's andpretty active but those stairs made my legs and knees so sore I had to crawl upand down them and days later still in pain. Each step is nearly half ameter tall and there are no rail guards on top of it being muddy andslippery. It was far easier to use the mess wire to climb up and down thecliff bank. I'm glad I decided not to bring my family with me because I can't imagine them trying to go down the stairs, it was so hard to get down even for 3 adults! Look at this cool ammonite impression in the shale! It was too crumbly andwet to extract so we just left them because they would break. We decided to stay near the bridge in case of rain and hugged the exposedsilt beds and gravel bars in the middle. We knew it was probably over-pickedbut I had hope. I tried to stay close to the "red zones" instead of themuddy shale. So we didn't go far from the stairs, just under the bridge inthe pictures. The river was super low in fact there was little water butanything wet was near freezing temperature. We got stuck in the mud and Ieven had no choice but to walk through the ice water to retrieve my shoesLOL next time I'm bringing the high wader rubber boots because it was the worsthaving near freezing wet socks for hours. I was stupid and didn't bring mysieve or trowel so we picked from on top. Honestly I really didn't knowwhat to look for except for black bone and baculite pieces as I have noexperience with the Ozan formation or shale. I'm used to picking for sharkteeth in gravel at Post Oak creek up in Sherman, Texas orcoral/ brachiopods in limestone or silica in Indiana. Everything here wasdifferent colors in the dirt and it was overwhelming but useful. I had thisinstinct to stick to the gravel beds in the middle (where I found all of myfinds!) although I was interested in the exposed red walls of the riverbank. I was wondering if a sieve and geologist hammer would be a good ideaand have a go at the walls next time we visit. Any pointers where to lookfor next time would be kindly appreciated! Omanyte with an ammonite aka Helix Fossil Moving onto my finds!My colleague found these massive baculites, some pretty black internalmoulds of shells, and shark teeth. My finds! I think I did okay for a picked over location at theentrance and no sieve. We only stayed for maybe two hours at most andagain I had no idea what to look for. I need help with some IDs! I have 7pieces of bone I am interested in, they look like marine reptile boneswhich is exciting! I'm sorry if my pictures are bad or need resized! I haven't been on a forum in years and I forget how to do everything. I am also uploading from my phone so I might have to edit photo or text spacing later. G. Please tell me this is something cool! I'm hoping this is a sea turtle shell piece with tooth marks on it! WTH is this......? Here is what I think they are.... A. Mosasaur "wrist" bone?B. Mosasaur or other marine reptile "finger" phalanges boneC. Mosasaur or other marine reptile "finger" phalanges boneD. marine reptile bone- possible tooth?E. unidentified marine reptile boneF. Marine reptile bone? (one of the curved bones near the eye socket?)G. Cretaceous sea turtle shell fragment!? (Has predator tooth marks!)H. ??? marine reptile tail bone piece? I. Fish vert J. Fish or small marine reptile vert K.Leptostyrax tooth L. Squali tooth M. Arrowhead Fragment N.??? Internal mould of a tree branch? It has a branching structure but it doesn't look like coral to me O. Corprolite? P.??? Help me with this one! Is it a rudist? Q. Baculites baculites baculites. R. Fossilized mouse incisor (recent) S. Cretaceous tube worms? They were everywhere to I stopped picking them up. T. ??? Coral? U. Petrified Wood V. Ammonite impression on shale W. internal snail shell mould X. Plicatula shell? Overall I loved the whole experience and when it warms up a little bit I will definitely head back out here! This is my new favorite fossil spot I have ever been to! I love the Cretaceous life fossils and the arrowheads found here are also very nice. Even if you don't like fossils there are neat stones, artifacts, and animals to find! Things I learned to help others plan a trip here: -The "Fossil Park" entrance to the river in Ladonia, Texas is the best place to park since it's FREE and open 24 hours/all days of the year. - Come here in Winter so there aren't any snakes or bugs -Make sure to bring your own food and water bottles as there are NO restaurants or stores nearby for 13 miles. Also bring TP in case you need to "go" in the woods. - IT WILL BE MUDDY! Bring an extra pair of clothes, shoes, socks, towels, etc if you plan on staying the day there. WEAR RUBBER BOOTS! I ruined my running shoes completely and had to fish them out of mud. I recondmend steel toe high-wader boots, after this trip I went to walmart and got a pair of tight fitting 16" wader boots for only $20 to use for next time! Also helps protect your legs from bugs, briar, snake bites, etc. - If you are like me and kneel in dirt or lay on gravel looking for fossils on the top exposed earth- bring some knee pads! - The stairs are very steep and will make you sore so be sure to do stretches and go down slowly -Use a long walking stick to test which parts of the river you can walk on. Example is that there are areas of one inch water you can walk across, but be careful as its tricky! Sometimes the shale is solid rock and other areas where it is just straight-up mud inches down and you will sink. - I recommend bringing a sieve and trowel! -Bring first aid kit and medicines like epipen if you have bee allergies. I also brought asprin, allergy pills, tums, etc. -There are wild pigs in this area, I saw boar or even javelina (not actually a pig) foot prints in the mud! -There are arrowheads, beads, and mammal fossils here! Not just marine Cretaceous fossils! Bring a backpack or container for your cool finds. - Do not go here if there is rain in the forecast or if it has recently rained a lot. The river cliff banks look like they could easily make mudslides and the river may fill up fast. -Don't go alone! Safety in numbers! I still can't decide if this is a good place to bring children or not, personally I wouldn't, but if you are an adult at least take another adult with you! There is no hospital nearby and I had poor cell phone service. You will need to fend for yourself with wild animal encounters and the geology here. It is very steep and muddy. In case of wild animals (wild pigs specifically) if you don't have a gun at least bring something to scare off animals and defend yourself with. I brought bear mace, airhorns, flares, and a hunting knife just in case. You will probably never use them but better safe and prepared!
  11. @KimTexan asked to see some of my jaw sections so here's a few from the North Sulphur River Texas. This is a nice mix of Xiphactinus and at least 2 species of Mosasaur.
  12. NSR shell -

    Hello all! Happy Georgious December! (almost 80 today!) Anyway, I got a rare day away the day after Thanksgiving and took my oldest back to the Ladonia Fossil Park on the North Sulphur River. We normally hunt upstream of the 2990 bridge, but thought we'd slow the pace down and get into the gravel. We knew we hadn't had any recent rains to clear out all the shale clasts that have filled the river bottom for the last several months. While much of the "Mush" has either dried and crumbled, or washed away, there is still a lot of it covering the ground. We found very few actual gravel deposits around the park except where exposed by hundreds of boot prints. We did find a few various shark teeth, a broken mosasaur tooth fragment, some Mastodon tooth enamel, - the normal finds around there. We noticed a family leaving and they had been digging around the bank where the gray clay/silt turns to a tan color - well above the Red Phosphate layer. One piece they had dislodged looked interesting and as we moved it, it broke open to reveal the fossil below. I've found fragments of this before upstream of the 2990 bridge, but never this much of it. I got a couple of pics right away, since this material starts to dry, shrink, and crack pretty quickly. We then wrapped each in plastic and soft cotton to transport back. However, the side of the fossil with the shell turned to dust and disintegrated. The shell is paper thin (like some of the larger white baculite shells) and is only the surface shown (meaning it doesn't curve around in the matrix and finish on another side. It's just this surface. One side has raised bumps and the other pentagonal depressions in the cast. First glance is the shape of a paddle (like turtle), but a) it's a shell coating - and b.) it has no bones. It's purely shell. It doesn't extend further into the matrix block. I'm good on most things Sulphur River, but this has been a mystery every time I've found it. Thoughts? Texas, North Sulphur River Ladonia Fossil Park Ozan Formation
  13. I found most of these a couple of weekends ago while poking around the North Sulphur River. The small baculite (left side middle piece) was still in a piece of red zone stone when I found it. I found the other three black rocks, were found further up the river all lying fairly close to each other in area of gravel. I can't find any obvious suture lines on them. The tooth I found last year on a trip to the same location. The other three are probably rocks but the top one has what looks like a micro fossil so I wasn't sure if it might be a coprolite. Any help here is greatly appreciated. A couple of closer shots
  14. Mosasaur vert and something else

    One of these I believe is a mosasaur vertebrae, but the other could just be a rock. It seems to have a few markings that seemed more biological than geological to me.
  15. North Sulphur River ID help

    I found this odd greenish piece a couple of weeks ago while walking down the North Sulphur River near Ladonia TX. Size is a couple of inches across the widest section and 3-4 inches tall.
  16. North Sulphur River Texas finds

    I have a few finds from my last couple of trips to the North Sulphur River in Texas that I'm not quite sure of. A few more images
  17. I headed to the North Sulphur River last Friday and found a magnificent coprolite in situ in the otherwise soft gray shale. I cleaned it up a bit, but as with most fossils from the NSR, the surrounding shale largely flaked away leaving the nearly 15 pound coprolite a fairly solid mass. Coincidentally, I had found a large isolated mosasaur tooth only a few feet from the spot two weeks prior. I positioned the tooth in one of the empty sockets and it would appear to be a fit. There had been a fairly good rain in the interim that looks to have dissolved a good portion of the matrix previously surrounding the chunk. My original instinct was that it had been deposited by a mosasaur, but the teeth marks in the jaw section look more shark-related to me. Too bad there's not a Coprolite of the Month. I am guessing that I might have a pretty good shot at it. Not quite the distinction of Vertebrate of the Month, but it's a start.
  18. Texas Pliosaur and Mosasaur teeth

    So I've gotten myself into an extremely rare deal- a mosasaur and pliosaur tooth both in the US for a small fee of 130 bucks or so (95 british pound) The goodies arrived today, and I might as well show em off. First off, we have a mosasaur tooth from the Ozan Formation of Fannin County. Knowing that the NSR flows inside Fannin County and is also part of the Ozan Formation, This tooth is probably also from the NSR itself. Although the seller didn't have time to do a full ID on the tooth and simply labeled it as unidentified, by extensive comparing with other mosasaur teeth from the area, I can promptly assume that this is cf. Tylosaurus proriger, meaning that after 11+ years of my life, I finally have a T. proriger tooth . Unless someone decides to be a donkey and counterID it. Next, we got a tooth that has been sought out for by countless collectors- a north american pliosaur tooth. As with other Texan pliosaur teeth, this one was from the Britton Formation near Dallas. Again, the seller labeled it as an unidentified pliosaur. This time though, IDing is difficult. Based on my knowledge, the two possible candidates are Brachauchenius lucasi and Polyptychodon hudsoni, which both have been found in this area. But as its hard to tell the difference between the two in teeth, I can't make a solid pinpoint. Maybe I'll just be biased and label it as cf. Brachauchenius lucasi because brachs are more iconic to me and due to the unstableness of the polyptychodon taxon. Although not as large as other's tylosaurus teeth, this one still kicks over 4 cm which is still pretty big to me. The pliosaur tooth is just over 2 cm, making it quite small but worth due to its rarity.
  19. North Texas Petrified Wood

    Does anyone know the source and age of the petrified wood found at Lake Lavon and North Sulphur River both NE of Dallas, Texas? shel67 found a piece of yellow palm wood from the North Sulphur River (NSR). http://www.thefossilforum.com/index.php?/topic/76090-i-need-help-with-this-one-from-the-north-sulphur-river/&tab=comments#comment-820122 I found a similiar piece at NSR that I thought might be palm or Snakewood along with many pieces of wood with distinct growth rings. I have also found petrified wood with distinct growth rings along the shore of Lake Lavon. All the petrified wood looks more recent, Eocene and newer, since palms and trees with distinct growth rings are not present in the marine Cretaceous rocks of north Texas and those types of wood are much more common in post Cretaceous rocks throughout the US. The currents watersheds of NSR and Lake Lavon include formations of Pleistocene alluvium, river deposits and mostly limely, clay to sand-sized, marine, late Cretaceous sediments. Eocene and newer rocks with wood are found upsection in south Texas and west in the Texas panhandle. See this map with the geology of the area (Texas geology map Sherman Sheet): https://www.twdb.texas.gov/groundwater/aquifer/GAT/sherman.htm Has anyone seen similiar in situ pieces of silicified wood in the Austin and Taylor Group rocks of north Texas? I have not. I doubt the wood is Pleistocene since you would expect to find larger, less rounded pieces from such recent deposits. There would not be enough time to petrify the wood, erode the formation and weather all the wood into small rounded pieces. Plus, nearby volcanic activity (and deposits) often is needed to provide a source of silica for the petrifaction. Little activity has occured during the Pleistocene in that area. I have two theories of where the wood came from. 1) The usually well rounded petrified wood found in the Pleistocene deposits represents reworked lag deposits from the post Cretaceous rocks that have since been eroded away. 2) The river drainages have changed. The wood was carried by former rivers that drained areas with Eocene and newer rocks from distant parts. Any other good theories?

  23. North Sulphur River

    Fun North Sulphur River Texas hunt. The big Tylosaur tooth and coprolite were my favorite finds of the day.
