  2. Found this need help please

    Found this in my neighborhood, I live in Dallas Texas USA. As far as geological history when I research the area it mentions most fossils found in Dallas Texas from the cretaceous period. It is small and looks like a piece of something but have no idea so now I’m here... any information would be helpful thanks. Length wise it’s 7.5 cm, width is 5.5 cm, and height is about 3 cm and the other is slanted so thing less than half of one cm.
  3. Jobsite Find

    Good afternoon to all. A colleague and I were doing some exploring in a creek bottom on our jobsite located in Fannin County, Texas. The creek we were walking in drains into the North Sulphur River. As we were walking we noticed a large bone sticking out of the creek bank. We decided to grab a couple of shovels and do a little more excavating. We came across multiple bones. As you may see in one of the pictures, we had to do a little digging in order to reach much of the bones, they definitely weren't just lying in the creek bank. I will upload more pictures with measurements. I kinda want to gauge if we stumbled across actual fossils, and if so we were hoping for some sort of inclination of what we may have found. The coordinates for the find are 33.4122,-96.0804. We were at least 15 feet below the grade of the jobsite in the creek.
  4. Please share some wisdom

    Hello everyone. I am new to the site so please let me slide if this is incomplete. I found this fossil in a small Creek in the west part of Dallas county in Texas. This area is upper Cretaceous but this bone is in amazing condition in my opinion so maybe more recent?? It is currently in storage so these are the only pictures I have right now. Any info or suggestions would be awesome and appreciated
  5. Dinosaur tracks in Dallas, Texas?

    Howdy, all. Apologies for the lack of specificity; I'm an amateur fossil hunter and am not familiar with all the terms just yet. I was recently looking for inoceramus clams in the bed of White Rock Creek when I noticed some strange depressions in the limestone. They were roundish (some with a hint of a triangular shape), around two feet in diameter, and spaced in a pretty even pattern along the creekbed. The more I thought about it, the more they seemed to resemble the tracks found at the bottom of the river at Dinosaur Valley State Park in Glen Rose. My questions are: Is anyone aware of dinosaur tracks along this creek? This wasn't at all a remote area, so it's hard to imagine that people just overlooked a bunch of dino footprints. You never know, though. If not, would this be worth bringing up to (for example) a research professor at a university? I have no point of reference for how common tracks are. I haven't taken any photos, but could do so. Thanks, all
  6. Fossil hunting legal question

    Hi all- I would think this has been answered but after searching I couldn't quite find an answer. I live in Dallas near White Rock Lake. There are a lot of creeks that branch off all through the Dallas area. I like to explore these on occasion (when I just want to get out on a Saturday) and for the most part I've been left alone (and had some success!). Does anyone have any "jurisdiction" over these creeks? I ask because I was exploring one that had houses on each side. OR actually their backyards that led to the house. Anyway, I was no where near someone's property (basically in the middle of the creek and on the sides) but a guy came down and said I wasn't allowed to look through there. I told him I was searching for fossils and he said he didn't care and he would call the cops. I was respectful and left but can homeowners actually do anything? As I stated I was not searching or messing with any homeowner property unless they are legally able to claim the creek. As a fossil hunter, I always want to be respectful but I also know people can be jerks sometimes. thanks for advice! Jeff
  7. Creek bed round thing?

    Found a curious circular thing on the bottom of the creek. It looks like a circular coral that I saw picture on the Internet once. Creek bed is around middle cretaceous period.
  8. I found these two in the Dallas area creeks today. It was washed down from upstream lying with other creek rocks. First one looks like coral and second one looks like rudists. I will let someone ID this for me since I'm new to marine fossils.
  9. Ammonite fossil or burrow ?

    I found this Ammonite few weeks ago. Looks like a burrow. If that is a burrow than I don't see want to waste my time and effort removing from surrounding rock. Too much work for trace fossil. Thanks
  10. Exogyra found in DFW creek

    I know this is a Exogyra oyster, but part of the fossil has been broken off. On the end, it seems to show fossilized flesh? What is that long thing? Internal flesh?
  11. Pleistocene mammal bone ID please

    Hello. I went down to local creek today and found some interesting mammal bones. These bones were found in 5 to 8 feet below the surface layer, but just above limestone gravel layer. I'm thinking this maybe some large animal, but does't think this is a cow bone since buried too deep.
  12. These are pretty small bits and pieces, perhaps not identifiable at all, but they were intriguing. I found them in Eagle Ford formation I believe in a creek in Grand Prairie TX. I found a small shark tooth in the same creek bed. It's probably too broken to ID. But perhaps the others are something interesting? The last two may be geologic. Thanks for any help!
  13. Large Shark Tooth Dallas, TX

    Well, "large" for what I have found around here anyway. Found in South Dallas, Texas. It was imbedded in a piece of Austin Chalk that rested right on top of the Eagle Ford Shale. I have found maybe 50ish shark teeth in the area but nothing even close to this size and preservation. I have never tried to identify any of the teeth, but this one intrigues me. Any ideas ?
  14. Post oak creek Texas

    After looking around at spots in dfw I had decided to check out post oak river on the west side of the service road I climbed down the embankment where I found a lot of shells like this one pictured no idea what exactly it is I’m very new to this and looking for info. I thought it might be a devils toe nail.
  15. Request help in ID for Dallas 1968 fossil

    I'm new to this forum, and would like to request help in identifying a fossil that has been in my possession for about 50 years. When I was a child growing up in Dallas, Texas, my father was a landscape architect who often visited job sites and had excellent relations with various sub-contractors. One day, he brought home a fossil "dinosaur bone" from a private residential swimming pool construction project. It certainly does appear to be a fossil bone from a large animal, and one can even see fossilized marrow in a hole on the specimen - but whether it's from a dinosaur or a mammal, I have no idea and would like some help with here. The specimen is approximately 90mm long, 60mm wide, and 50mm high. I haven't weighed it. Although I've worked in museums for much of my professional career (and so I'm motivated both by scientific curiosity as well as a strict adherence to scientific rigor), I've somehow never brought this specimen for any expert to identify. Don't know why - just didn't. My father is still living and a couple of weeks ago I asked him if he remembers any additional information on exactly where, at what depth, etc. this specimen was found. Unfortunately, he does not remember any additional information or context. I'm including some photos here, but of course would be happy to provide additional ones, or to provide any other information that would prove helpful in identifying this specimen. And thank you very much in advance.
  16. Looking for Fossil Hunters

    Hey Everyone! My name is Hogan and I'm an Associate Producer at Rugged Productions. I'm currently doing research for a new show concept and I'm looking for the best and most unique fossil hunters / collectors / buyers / sellers! Please let me know if this reminds you of someone (or of yourself). Thank you!
  17. Eagle Ford Fish Fossils

    Here are some of my fish fossils from the Eagle Ford group of North Texas. Apsopelix sp.
  18. I was cleaning some matrix I got from the Kamp Ranch formation in Dallas last weekend and found this tiny thing in the matrix. I’m wondering if anyone can tell me what it may be without it being fully exposed. The picture quality is not that great. I sure tried to get better pics, but wasn’t able to. It is 5 mm wide at most. So it is difficult to get a good close up pic of it. It’s 4 sided pyramid shape with a peak in the middle that almost looks like it has a groove down the middle of the peak. It was in a loose fragment of matrix I pried off a slab. Some of the surface of the item remained in the negative half of this. That is where you see the lighter color on the top and sides. This is a pic of it when wet. Top looking down view. Top down view again while dry. Side view from one end. Side view from the other end. Maybe it’s a funky shaped pebble, but I don’t think so. All the other stuff in the matrix looks like shells or shell fragments along with shell and ammonite impressions and some fragments.
  19. I went exploring today. I hit 3 places. The 1st two were the Ozan in Rowlett. The first 2 were a busts, but the 3rd was in the Eagle Ford in Dallas and it was a very interesting place. I can’t say that I found specific fossils per se, but I did find the product/remains of prehistoric animals. I was ecstatic with my finds. Septarian nodules have been on my bucket list of things to find. I found a hill full of them!!! I got there less than an hour before sundown and was thrilled with what I found. This one is very cool, but I’m not sure what the original creature actually was. The only thing I can think of is that it was an ammonite and maybe the septa became crystal filled, but that is a total guess. The curves on the edge and sides don’t look right, but I’m not sure exactly how these formed in the particular area. It honestly looked like the badlands or something desolate with nothing growing there and was a very fine soft gray shale. I found a lot of what I think are aragonite crystals at the site as well as some other beautiful crystals. I have never found any crystals in this form before. So I’m thrilled and hope to go back tomorrow if I don’t get paged into work tonight. This is the one I’m very curious about. Maybe some of you may have seen something like this before, but I have not. I think it is super cool though. I’m pretty sure it was once a critter of some sort. I believe it is a septarian nodule, but there are no septarian marks externally like you usually see. When I was washing off other nodules I found, as I was washing, the exterior began to slough off and the septarian lines became visible. There are basically 7 bundles of crystals across this thing. Some are kind of merged. #1 This one has me most curious of all. #2 other edge. Right edge is encrusted with what I guess could be considered pyrite disease, rusty material mixed with crystals encrusting it. I have found an ammonite before that was rusty with crystals like this. #3 Close up of the encrustation with small crystals jutting out. They’re hard to see. #4 one side. The other side is less descript. The curve on this doesn’t look ammonite to me. I found some pieces that looked almost turtle like, but I don’t know turtle stuff when I see it. I will say the rock material is soft and is a fine shale like texture and material so when wet it becomes slick almost like soap, but no bubbles. This is a 2nd find in the same area. In the center below the crystal on top is a sea shell. Wish I knew what kind, but not much is exposed. All you can see is the mother of pearl inside the shell. #5 note crystal branching in 3 directions below shell, there is also a beautifully formed crystal on top that is pristine and wafer thin that was part of the septarian, but the non-crystalline material has eroded away leaving the flower petal like crystal. #6 This is it from another side. You can see more of the septarian sections. If anyone knows the critter this arose from or the crystal type I’d like to know it. Calcite and gypsum are most common here. There is brown too. I also found stone with green crystals. This is a 3rd find in the same area. #7 I found these bars just laying on the ground like this. They looked so peculiar. I couldn’t figure out what they were. I thought they looked a little like columnar basalt, but knew that wasn’t it. There was a small nodule in the ground less than a foot away that was cracked all over and filled with crystal. I wanted to dig it out. In the process of digging it out I found another hard object just under where these were. I thought it was a solid rock, but when I started to move it the rock came apart in these shapes. #7 cleaned up a little at home. #8 one up close. I believe they are all covered in aragonite or brown crystals. I’ve been told that when an ammonite is encased in a nodule and then the mineralization process takes place that often aragonite crystals form as a result from the nacre in the ammonite shell. I have not found the source of that claim though. Can anyone tell me how these formed and what the crystal is? Is it aragonite? How would I know? I can provide higher resolution pics upon request. I had to make these low res to get all of them in here. @Uncle Siphuncle, @Fruitbat and @BobWill you 3 have hunted the Dallas and North Texas area for many years. I assume you’ve seen these sorts of things and may have insight you can share.
  20. Hunting in Texas

    Hello all! I am wondering if I could get some ideas for places to hunt fossils in Texas. We are currently just north of Dallas and will be heading sort of diagonally to the big bend area. Any ideas of good spots to hunt fossils aong the way. (Some of the trip will have a 9 year old. Any kid friendly spots also appriciated) thanks all in advance!
  21. Here is a very nice little gastropod fossil I found in a creek about 10 miles east of Dallas recently. Once I washed it off well I was shocked by the detail, and even colored stripes! Can anybody give me more info on this? I will post it to the Gallery with more info. Is it very common to see color in fossilized gastropods? Thanks again! KP
  22. Fossil bone, wood, or other?

    I briefly explored an old creek outside of Dallas, TX yesterday; a creek I used to explore as a kid. I didn't find much at all because it was so overgrown and difficult to access these days. I found a few pretty river rocks, a nice little shell fossil and what appears to be either a little piece of petrified wood or bone. I took macro photos of it tonight. Please let me know what you think. I'm baffled. Larger fossil bone pieces, with this color/texture, have been found in this creek many years ago.
  23. Help me identify this fossil

    Can you please help me identify these? I found them in my backyard in Fort Worth (Dallas), Texas, and approximately 15in diameter. Are these things that i should find someone to give them to or are they okay to throw away? thanks!
  24. 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 great price. 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 . 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.
  25. Planning Trip To Dallas Area

    Hey guys. I'm thinking about taking a trip to the Dallas area to do some fossil hunting in the next week or so. I'm a newbie and have been searching the internet to learn how and where. I'm from Lake Charles, LA. and I don't really know anything about Texas fossil locations other than what I've read, such as, Mineral Wells, North Suphur River, Lake Benbrook, and a couple of others. My daughter and I are interested in trying this to see if it's something that we will like. I used to dig arrowheads in LA. 30 years ago and I really did enjoy finding a nice one. As a couple of newbies, finding anything would be awesome! I thought that my first stop would be Mineral Wells since the internet makes it sound like I'm almost guaranteed to find something. Any advice for my first hunt will be much appreciated. I will be pulling a camper along with me, so any campsite info. close to the fossil locations would be great also. Thanks Stephen
