  1. ID help for a rank beginner

    I visited the North Sulfur River for the first time today and found some great (to me) stuff. Some help with identification would be appreciated. The bones. I didn't expect to find this many bones. Can anyone tell what kind of femur that is? It's short, but very hefty. And it's flat, not round like a human femur. Standing on edge in this photo, you can see how flat it is.
  2. NSR, April 3rd

    I made a trip to the NSR today and had a blast. Let me say up front that I am a rank beginner, and this was my first real fossil hunting trip, unless you count a visit to Mineral Wells Fossil Park with a bucket a few weeks ago. It was a dark day, but I was afraid if I waited, the next round of rain would have the river too high. I found some cool stuff. I'll be starting a thread in the ID forum for help identifying things. I'd especially like to know about the femur and tooth I found, so if any NSR experts can help out, I'd appreciate it. Some random thoughts on today's trip: 1. NSR is one of the coolest places I've ever been. I get why it's so liked and popular. I'm going to visit it as many times as I can this year before it's a lake. 2. Those steps were made for someone who's 6'6". Lets see a show of hands of who can traverse them making steps like regular steps. I could to it, but I had to shift my (full) pants pocket to one side to make such a giant step. And they end before the river bottom. Getting up that muddy bank on a rainy day to get to the first step is no small task. 3. I would have liked to hike much further up the river than I did, but with more rain expected, it seemed prudent to not wander more than a mile from the bridge. I was happy I was still able to find cool stuff, even without a long hike. 4. It got cold! My forecast in Gun Barrel City didn't call for anything lower than 60 degrees today, and it was 60 something when I arrived, but I noticed it kept getting colder, and by the time I got back to my van at 12:45, it was 44 degrees. That's too cold for wading a river! 5. I brought home more insignificant stuff than I should have. Is that a beginner thing? 6. I'm an old guy (69 on Sunday), but fit (still average 100 miles a week on a bicycle, and have for many years). Fit or not, I'm too old to be making trips like this by myself. So, I'd enjoy joining someone else who's going to NSR. I don't mind separating and searching on my own in the river, just take a moment before you leave to make sure I haven't fallen and broken a hip. 7. If I find something bigger than this, I'm going to need a bigger bag. ]
  3. mosasaur quadrate fragment

    From the album North Sulfur River

    My best guess is that this odd piece of bone is a fragment from the lower part of a mosasaur quadrate.
  4. Original Baculite Nacre

    From the album North Sulfur River

    These wonderful colors you are seeing are from the original iridescent nacre of a baculite from the Late Cretaceous. The colors are caused by "thin film interference," in other words, by the structure of the nacre.
  5. My daughter and I took our very first fossil hunting trip to the NSR near Lavonia, Texas last weekend (10/27/2019). We dug a little, sifted (just with our hands) a little, and just walked around, but we still had great success finding treasures! The steps down to the river bank are impressive. Some of the steps are about 3 x 3 feet square, and the length of the stairway is about 70-80 feet. The bottom of the steps have a large, nearly vertical slab of concrete that is easier to slide down than it is to climb back up. especially with about 5 pounds of very sticky mud stuck to our boots. There is also a mud pit at the bottom of the slab to navigate that makes coming back up a bit of a challenge and a workout. Of course, afterwards, we found that there are two much easier to navigate entry/exit points, one to the left and one to the right of the steps. And we found out later that on the previous weekend, this site had hosted a group meeting for fossil hunters. So were feel particularly fortunate to found the things we did.
  6. North Sulfur River bone?

    Found this yesterday in North Sulfur River where I found the mosasaur vertebra. I'm wondering whether this could be from same animal?
  7. What did I stumble upon?

    Found on the north sulfur river today. It’s cross hatched… I know it’s a fossil of something, but I am clueless as to what. A girl I met with found something similar and we had no clue.

  15. North Sulfur River Fossil ID

    Hello! I Found this while fossil hunting at Ladonia Fossil Park in Texas, anyone know what it could be? Thank you!
  16. I went fossil hunting at the North Sulfur River (NSR) in mid December with @believerjoe and Cathleen, @cgmck a local fossil hunting buddy of mine who is a semi-retired environmental geologist.. I’d been trying to work out a time to go hunting with Joe for close to 6 weeks. He had extended the offered sometime after I had met him at the Ladonia Fossil Day event on October 20th. He offered to take me to teach me how to spot mosasaur and bone material in the NSR. We are both on the Dallas Paleontological Society Facebook group page and crossed paths on there quite frequently so we were acquitted on there and on TFF. We set 12/15/18 as the tentative date, but rain kept threatening to delay our hunt. Up until Friday evening, 12/14 I wasn’t sure we were going to be able to hunt. If the water was too deep it would be pretty murky, making it hard to spot fossils. Saturday dawned bright, clear and chilly. Water levels were huntable. It would be in the mid 30s when we were to meet at 8:00. We would be walking through a lot of water. I have rubber boots I usually wear in the wet and cold weather in creeks, but I knew the water would be high. I’ve hunted the river when the water was high like this and it prevented me from going up the river and creeks I wanted to go up. So I opted to buy myself a pair of hip waders before the trip. I found these for $25! They were 50%. The shoe size is a man’s size 7. They said they ran big for men. Men’s shoe size 10 is bigger than women’s 10 so I took the risk and they fit fine. They were comfortable and worked great. Anyway, I packed my hunting gear in my car and then a backpack with another pair of socks to keep my feet warmer when walking in the cold water, extra leggings, gloves and hat to put on once I got there. I didn’t do my hair. I was planning on wearing the hat. I threw my favorite ball cap in the pack too. When I got there I realized I’d left my backpack with the extra clothing for warmth at home! I was going to be a bit chilly. Especially my feet. My boots aren’t insulated. My hair was going to be all over the place with the wind. We met at the Ladonia Fossil Park and then transferred our stuff to Joe’s pickup truck. Joe drove us to a place he likes to hunt. We got out, put on our gear and walked down into the creek. Joe didn’t think the water was going to be too deep in the creek so I opted to wear just my boots rather than the waders. First step into the creek there was a rudist fragment that Joe pointed out. It was kind of big and we were going to be walking a long way. So, I opted to leave the rudist there. I walked maybe 30 feet and found a piece of turtle shell. Yay! My first piece of Texas turtle shell. I’ve found turtle shell elsewhere, but it was Miocene. The one on the right is the one I found. Joe found the other piece and let me have it. We walked on up the creek and Joe kept pointing out mosy verts here and there. I found one on my own the whole trip on the second leg of this creek hunt. He’d spot them from 30 feet away half covered. It was impressive how he could see them so far off mixed in with all the other rocks and gravel. Some were pretty little too. I think maybe 6 or 7 mosasaur vertebra were found total. Cathleen has always had higher fossil quality standards than I do so she turned all, but one of the vertebra down. She took the best one home. The water was pretty deep and cloudy so it limited finding fossils considerably. There were numerous places we came to where the water was fairly deep. Joe’s boots came almost to his knees, but mine were maybe 10 inches tall. So, we had to walk carefully as times to find where the water was more shallow so that I could cross or proceed up the creek. There were many places where there was no gravel in the creek and the bottom was the typical slick gray shale of the Ozan. We all had walking sticks, which helped considerably, especially with the mud. When you hit the mud sometimes you don’t know if it is safe or how far you will sink. Walking sticks served as a measuring stick for mud depth. Which reminds me that I need to put a mark on my walking stick for boot height and water depth. We came to a few places that we tried to walk through and sunk maybe 10 inches max, which isn’t too bad by NSR standards. Other places we avoided and went around. This is Joe and Cathleen in the creek. See the large blocks of stone in the creek. Well, I had been seeing stone like this in the river since I have been hunting it, but I had never known the source. Come to find out it was imported stone to help with erosion control. This is a piece of it up close. It is a sandstone type material. Now I know it isn't from the river. I have been wondering all this time where this formation was, because nothing in the description of the formations in the area say anything about this type of stone. So, it has been a complete mystery all this time to me. The mystery is now solved. We hiked on up the creek for a while without event or really finding much of anything. I was finding petrified wood left and right. The pieces in this feeder creek were, in general, larger than what I usually find in the river. Here is some of the pet wood I found. These are my favorite pieces. The first one actually looks like it has a stain on it. You can see the sharp peak pointing to the left. The second has lots of texture and contrast in color. The third is a nice deep, brick red that you can't tell from the pic. I could be mistaken about the last piece, but I think it may be a piece of palm root wood. As I walked along I came to a piece of what I initially thought was petrified wood, but as I looked at it I realized it was not petrified wood. I thought it looked like a fish tail, but I had never found fish fossils in the NSR area. Joe came over and he initially thought it was pet wood too, but then he turned it and said “Wait a minute, that is a piece of fish. “ Woohoo!!! I was quite excited and happy about that find. I think it was Anthony Maltese who told me he thought it was "probably a Pachyrhizodus or a Plethodid based on the segmentation of the fin rays (top left of the picture)". I think he may be @-AnThOnY- on here, but I could be wrong. We walked on and found a few more vertebra and then we came to a place where the water was too deep for Joe and I to cross. I do not mind getting wet, but when it is around 40 degrees I prefer to stay dry. At that point we had been walking for a little over 2 hours. We turned around and headed back. The walk back went a bit quicker. Maybe 1/3 of the way back we were walking in part of the creek we did not walk when going in. The shale was not flat on the creek bottom, but at an angle, slanting towards the center of the creek and deeper water. I stepped just wrong on it and down I went. As I was going down, I tried to ensure that I fell in more shallow water and that I didn’t flood my boots. Somehow I managed to be reasonably successful in my attempt. I landed in a sitting position in maybe an inch or so of water with my knees bent so very little water got in my boot. Still my back side and upper thighs got wet. I stood up and began to attempt to slide forward on the shale so as to not fall again. Cathleen was right in front of me. Before I made two steps she went down too. She was wearing full waders that came up to her torso, but she was not quite as lucky. Water got into her waders and when she stood up she could feel the icy water flow all the way down her back, then down into her boots. It was in the low 40s now so it had warmed a little, but it was not a pleasant feeling to be wet in 40 degree weather, but we toughed it out. It was when she stood that we realized that we had not walked this side of the creek on the way in. We immediately crossed the creek to get to less slippery ground. We made it back to our entry point. It was almost noon. Cathleen said she needed to drive back home for something planned with family. Joe drove us back to our cars. I emptied my pack, which was full of petrified wood mostly. Then Joe and I drove back out to the creek. I put on my waders at this point. We headed down stream to continue looking for mosasaur material. I found one little very beat up vert, but I also found several pieces of Pleistocene bone and a horse tooth. The horse tooth is likely modern, though there are not many horses in the NSR area so it could be Pleistocene. Weird thing about a lot of Pleistocene bones in Texas is that many of them are not fully mineralized and so they are fairly soft and light in color and appear modern. So it is hard to tell if something is modern or Pleistocene. Even the mammoth bones in Waco are not mineralized for the most part and so they are fairly fragile, white and look like modern bones in texture. Joe and I proceeded down the creek. I was walking on the bank on one side of the creek and he was walking in the water in the creek. I came to some deep mud and contemplated whether I should back track or attempt to make my way through it. Ahead of me the mud got much deeper. I decided I better make a 90 degree turn and cross over to the other side. I had my walking stick with me and tested the mud to make sure I would bottom out rather than keep sinking. The mud stopped and hit creek bottom at a little over 2 feet deep, up past my knees a ways. I figured I’d be OK. I went ahead and walked through it down into the water. It was tough pulling my legs out, but I managed OK until I was in the water. I was trying to balance on one foot and with my walking stick so I didn’t fall over into the water. I’d managed a few steps, but then I was having trouble pulling my foot out of one spot. Joe came over and took my hand to pull me out and hopefully keep me from falling down in the water as I pulled out of the mud. I made it out successfully with Joe’s help. If I had been alone I am not sure I would have taken the risk. Not with the water being so cold. It was icy cold. It wasn’t the worst mud I have encountered, but it was some serious mud. We moved along without event after that. I had told Joe I wanted at least one hour to hunt the red zone before I left the NSR. So after a bit we turned around and headed back. Joe is not a fan of the red zone. He says the preservation of mosasaur material there is not very good there. I have not found mosasaur material there, but it is true that a lot of red zone material has either pyrite or gypsum. Pyrite is the most common. If iron was present in the fossilization process, frequently the fossils develop pyrite disease when exposed to the air and they can disintegrate into dust. I am a fan of the red zone, because that is where some of the best ammonites come from. We made it out of the creek and Joe drove back to the fossil park. It was about 3:00. These are the finds from the creek. The long thin light one is a metapodial from something like a deer or the likes. I am not sure about the others. The horse incisor, from a young horse is at the bottom middle. These are the mosasaur verts and turtle bone that Joe pointed out. The horse tooth is there to prop the one vert up. I think I may have connected another piece to the NSR puzzle. See the white calcium layer on the vert on the far left? It is common to see this on fossils. I could be wrong, but I have come to believe that fossils with this white layer most likely come from the Roxton formation. My fish piece has the same stuff on it. I don't think I put my little worn vert in one of these. I will post is in my overall picture at the end. I will be back in a bit with the trip to the red zone. I want to thank Joe for being so kind as to take me hunting so I can learn from him. I hope we can go hunting again sometime so I can learn more. Joe is the mosy guy. I am the ammonite girl. So, it was helpful to hunt with him to broaden my knowledge.
  17. NSR Unknowns

    Hey yall! These are a couple of items that were found in the North Sulfur River that I am uncertain about what they are. One appears to be bone, but has a rather porous and bubbly side and a flat and smooth other side. The other looks to be enamel, possibly from mastodon?? Thank you!
  18. North Sulfur River Insect/Arthropod?

    I was out at the North Sulfur River on Saturday. I found a number of cool things. This one is a mystery to me, but it seems very rare and pretty neat. I’m not sure it’s even really identifiable as to a class or order, but I thought I’d ask. It needs more prep, but I’m not sure how much more there is to uncover. Above you can see what look like 2 legs hanging down and possibly One on op. Below is the same thing invented. Another pic from a different angle. I can’t get any closer on the small details. I can see the texture of what I believe may be legs on the bottom of pic 1, but they aren’t crustacean legs. I guess they could be antennas, but I’m not sure antennas are segmented like that. If you look at what appears to be an appendage on the top it does have bumps on it. Any thoughts?
  19. Xiphactinus Audax

    Xiphactinus is one of my favorite type of species that is a total fascination because of its size, the teeth, and just plain scary to think this fish use to to live. I've been pretty blessed to find some good Xiphactinux material in the North Sulfur river including some verts, a couple teeth, jaws, and some associated wash out from a couple different ones I have yet to find the source. I couldn't imagine swimming and having a tarpon like fish the size of a Great White shark come up from behind and swallowing me whole. Below are the various Xiphactinus fossils I've found in the Sulfur aswell as photos of the 3D Xiphactinus Audax cast skeleton made by Triebold Paleontolgoy as well as the largest Xiphactinus ever found which came from Kansas and was prepped by Triebold.
  20. Had another opportunity to hit the North Sulfur after several good rains. Once again, fresh rock bars everywhere and my buddy and I went home with our pockets full! I found at least 15 mosasaur verts, 20+ teeth, a nice coprolite, shark vert, etc.. I included a few pictures of some of my better stuff. The 5 points pictured together were found in the NSR They include a couple killers! For the old, pointy rock hunters, I included a pic of all the points from this weekend. Found 20+ in one spot in Fannin county that was clearly a large Caddo camp. Enjoy! Just a thought... I get asked a lot where I go and how i find so much stuff. I never really give up my exact locations because I work hard to find them. However, I want others to be able to enjoy this place as much as I do so here are a few tips to help folks who are new to hunting the north sulfur. Fossils and points don't travel upstream after being washed away from their spots. The further downstream you can search, the better. I'm really tall and my eyes are really far away from the ground- I know this sounds silly but my point is that the closer you can get to the ground the better. I find lots of my smaller stuff on my hands and knees and use readers to really "zoom" in. Good knee pads are essential. Proper footwear. In the winter I usually use a tennis shoe with a heavy duty 5mm neoprene boot as a sock. I also screw ice studs from Stabilicers into the outsole to keep from slipping on the blue, butt breaking rock. When walking the river, this trick is a necessity after you try it once and realize its benefits. Points are easy to find once you train your eyes. Learn to recognize the colors of flint and other common materials. Recognizing blade edges helps me. Learn where the indians camped. Lots of reading and scouting involved. Good luck!
  21. I found this ammonite on Saturday. It is the best Trachyscaphites springer I have ever found. I think it is a T. springer. I assume the other ones I have are males and maybe this one is a female. I don't know much about sexual dimorphism in this genus, but it does exist. When they say there is dimorphism is the female is bigger? It is so very different from any of the others I have. I know there is another species of Trachyscaphites in the NSR, but I don't know what it looks like. I really like this one though. It is free standing too! Bonus. It has some damage on the dorsal venter and the aperture. It also had some pyrite on the umbilicus area (I can’t really see an overt umbilicus since it is so involuted). My prep work is still very crude. There is so much I need to learn. I just keep at it and learn by trial and error though. I don’t have pneumatic tools. Here it is. See the white film on the right half? The white on the left half is nacre, but some of it has the film on it too. This is from the red zone of the Ozan formation, Cretaceous. I doubt it matters, but I am wondering if the film layer is pyrite in nature or gypsum or something else. I have specimens from the Britton formation of the Eagle Ford group, which have a gypsum film on them and this looks a bit little that. But that isn't my main question. It is just a curiosity. This is the other side. You can see some pyrite at the bottom left along the umbilicus grove. I have a number of these, but this is the first where I can actually see suture lines mostly at 11 to 12 o'clock down the midline and on the right. I am going to tag @Ptychodus04 and @RJB on this. I don't know if Ron is familiar with fossils of this matrial and matrix, but I imagine he is. I am pretty sure Kris is. Questions The film issue 1. Do you think I should attempt to remove the film? I think I should. See the tubercle by my thumb in pic 2? There was a tiny fleck of white showing so I chipped away at the red clay and revealed more nacre under it. So I believe there is still nacre under some of it on the left 2. What is the best way to go about removing it? I was thinking of using sandpaper, but I don't have much experience using sandpaper on fossils. I have a range of grit up to 3000 (or is it down to since the grit is smaller and finer?) The nose issue I am calling it the nose since it looks like a little nose. It seems to be the first part of the first visible whorl. 3. Any advice as to what to do with this part. I am not sure what to do with it. At times I prep haphazardly and then I think I have damaged it and I get paralysis of analysis and that is where I am on the nose. I have removed some matrix from the top, left and right. I think I might have gone down into the nose on the right side some. It is hard to tell where the matrix ends and fossil begins. These are other views of the nose. The lines on the nose are from me scraping away, thinking I was on top of ribs. I am not sure if there are ribs there yet. Like I said my prep skills are pretty crude still. The other side of it. I still have some matrix to removed on the side there. I think part of it is chipped away, but I am not totally sure how it is supposed to look. Maybe it got crushed. It just looks odd to me. I have several other of this species, but I think they may all be males or something. They are more open, the whorl does not cover the umbilicus and they are much flatter and smaller. The pyrite issue. I know I have asked these types of questions before about prep so sorry for the repeat. 4. What is the best way to address the pyrite to keep it from coming back? I have scraped most of it off already. I have heard people say to soak it in Iron Out and I have that. But I am concerned it may hurt the fossil. I guess I could experiment on other concretions I have that look like the same, but are rock and not fossil. 5. What should I do as far as long term preservation to slow the progress of pyrite disease? I think someone recommended Butvar. I looked into buying it, but I got sidetracked by trying to figure out which was best. Then couldn't find what was best and kind of forgot about buying again. 6. What is the best Butvar or product to use for sealing it? I looked at buying some on different sites. Paying so much for shipping irks me. I am spoiled with Amazon Prime and just don't think about shipping costs. I have a buddy who works at Eastman. I asked him if they had a store where individuals could purchase products like Butvar 76. He said no, but he would see if he could go ask for a sample The museum supply site. It has Butvar-80 for $34 for 1 kg and $15.53 for shipping. I don’t need 1 kg. Talas has Butvar-76 500 g for $17.50, but then is charging $14.64 for shipping! I have seen people reference McGean-15 or Vinac and they seemed to prefer it over Butvar. 7. Can anyone tell me the molecular weight of the Vinac or what grade of polyvinyl acetate Vinac is? I think my buddy could come up with that for me more easily since I think he manages production of a form of it. I found something called Vinapas. I have not looked at the shipping on this site. Here: http://www.conservationresources.com/Main/section_37/section37_08.htm PVA Resin Solid Vinapas This consolidant is a polyvinyl acetate solid suspended in granular form, with a molecular weight averaging 51,000 and a melting point of 50 C. It is used as a consolidantfor porous, dry, non-metal objects-particularly those found in digs. This is typically applied in concentrations of 20-25% I.M.S. with a soft brush. It may also be used as an isolating varnish and thermoplastic adhesive. Item # Description Price SY01 Vinapas, 1 kg. $22.00
  22. What bone is this?

    Here is another bone from the North Sulfur River that is Pleistocene in age. I found it Saturday. I am not sure what it is or what it is from. It is slender and flat towards the bottom and roundish on joint end, but still a little flattened. My wild guess would be ulna, but it is just a guess. I’d like to know what it is from. Long edge side 1 Long edge side 2 The joint end side 1 pic 3 Joint end side 2 pic 4 Pic 5 looking straight down on joint end Pic 6 This is the other end of the bone.
  23. Is this a piece of coprolite?

    Yesterday I went hunting in the North Sulfur River in North Texas. Could this be a fragment of a coprolite? Pic 1 and 2 are same pic different lighting. I was trying to bring out the button in the center of what I’m calling the bottom. Pic one brings it out, but it is grainy. Pic 2 you can zoom in better. The center kind of has a pinched button look. # 3 the top. It looks like clam shell fragments possibly. The next 3 are side views. The whole thing is dome shaped. @GeschWhat
  24. I took a trip out to the North Sulfur River today. These bones were one of my finds from an avalanche that had happened. I believe they are Pleistocene in age. They are not heavily mineralized like the Cretaceous bones found in the river. They are at least partially mineralized though. I have never found and Pleistocene bones. This is the full length of the bone. One end is flatish and the other convex. This is a view from the side. I believe it may be a vertebra. The back side is broken off where spinous process would attach. Side view. Convex End view This is another bone found at same spot a few feet away. I think it is a sacral piece. I have a couple more fragments too, but they do t seen diagnostic. Can anyone tell me what they are from?
