  1. Tiny Ammonites ID

    Looking for an ID on two tiny ammonites that I have had in my collection for a long time. The id that I have on them is "Acanthoceras worthense" from the Cretaceous of Roanote, Texas. Just looking for confirmation or correction. Thanks.
  2. T-Rex toenail?

    There is a spring fed pond in Weatherford, Tx. that has a grouping of the largest fossils that i have ever seen. These fossils were gathered and placed in a circle around this pond by ancient Indians who lived there prior to and during the time that my friend's ancestors purchased the land. Some single bones are larger than my car, only a very few could be picked up by man alone, and I got a few by the owners permission, and here is one of those!
  3. Mineral and fossil Texas finds

    I used to have a rockshop with my ex-husband, who did lapidary and had a major in geology. His collections are fascinating but currently gathering dust in his ancient workshop. So, I have always had an interest in rocks and fossils and such. My collection is tiny and most of this I have no clue (and too much imagination) about what it actually is. I have a few items that I am curious about as to their true identity. One I am pretty sure is just plain mud or some sort of concretion. The minerals, well, I am guessing something like calcite. I think I have a palm heart as well but, hey, I very well could be wrong! Then there are two fossils I am sure you folks can give a name to for me. Thanks very much for your time and help! First is probably nothing more than some interestingly patterned mud. Then there are two pics of maybe some kind of fossil shell. Next is...??? I'm usually wrong, but maybe a type of coral? The top reminds me of a slab of petrified palm, with the monocot structure but the layering is more like individual tubes. Then there's the possible palm heart. It is heart shaped and please don't laugh my husband painted it red. The top of the heart shape is indented (concave?) and pardon my imagination, would be where the palm tree grew from the palm heart. Or maybe it's just a heart shaped rock but there were many of these where I found it. Lastly, there are two crystalline (minerals) and one goes from clear to yellowish to orange and red. The other one looks grey but is a bit golden honey colored under a bright light. The growth reminds me of petrified wood and the crystals are more long and slender. All but the heart rock were found on my property near Castroville TX.
  4. North Texas Creek Hunts

    I managed to get in 3 hunts on my 14 days off from offshore this time. I found more artifacts than fossils but I did manage to find a nice Mosasaur vert, shark teeth and a really old coke bottle. This is a mix from Post Oak Creek and one more creek that I hunt. I gave away all the teeth except for the perfect ones to my buddy since it was his first time ever hunting.
  5. So in August 2016 I stumbled upon some bones sticking out of a creek in north central Texas. I dug out a partial skull of a protosphyraena fish. I looked for more but this was all I found at the time. Late Cretaceous Atco Formation- Austin group 86-90 mya
  6. I have recently been getting into the world of fossil preparation. The only tools that I have so far are a dental pick given to me by Roger Farish, and a few other picks of about the same tip size that I bought at Home Depot. They are doing well for me now with the kind of basic preparation that I am doing with the Austin Chalk. The problem that I have is trying to clear away the dust and small rock bits while I am preparing the fossil. So far I have been just blowing it away with my mouth, but in the process it is hard not to breath in some dust, which I know is not good for me. I have tried wearing a dust mask and then taking it off momentarily to blow away the debis, but that is annoying to deal with and I usually still breath in dust. I know that many of those on here who prepare fossils use air abrasive systems where the dust is blown away by the exhaust from the front of the pen. I am wondering what I can do with my setup. Compressed air? Vacuum? Any and all ideas are appreciated.
  7. Tylostoma Tumidum?

    A lower Cretaceous Tylostoma tumidum, yes or no? I obviously did a little research on this snail. I picked this up is a in a pile of rocks from a quarry some where in Texas. Even with a chip off the top spire it's twice the size of a couple similar snails I've picked up.
  8. Mineral Wells Texas, Nut or?

    A veterinarian friend of mine went on a cub scouts camping trip with his son. The group found this fossil at Mineral Wells State Park located in Texas. The cub scouts are curious if this is a plant or animal fossil? Any identification help would be appreciated. Thank you for any help!!! Jill
  9. Found this in a field around Quihi, TX. The object imbedded in the stone is what we always called a meteorite. Some of these 'meteorites' I have collected are grapeshot, most about this size. I don't know what it is, but it is solidly imbedded into the stone from what may have been a hard impact as from a projectile or, falling from the sky. Any ideas? Is it cool?
  10. I went to Post Oak Creek in Sherman, Texas today, and I found quite a good mix. A few of the teeth were a bit unusual. In the 4th photo I have a few questions. On the top row, second tooth from the right, is that a rodent tooth? Then (4th picture) second tooth from the right, that one has a strange “hook to it”. Also, second row, third from the right. Anyone know what those are? Thanks in advance!
  11. In March of this year I found a heteromorphic ammonite that has had me curious ever since. So yesterday I finally sent an email about it to a local ammonite expert, Ron Morin, who is associated with the Dallas Paleontological Society. I had a correspondence with him in May of this year as it related to him identifying my Phlycticrioceras trinodosum heteromorphic ammonite which I recently added to 'Collections'. That's when I first talked to him. Then at the Dallas Paleontological Society's Fossil Mania event in October, I was talking to Roger Farish about my unidentified ammonite. He recommended that I contact him again for identification. Here is the email and the pictures that I sent him yesterday. I will post an update to this thread when he responds, which from my experience might be weeks. I have edited it to remove any slightly sensitive information like my name and more specific location information (I'm paranoid), as well as to fix any grammatical errors and to add relevant reference designations in between the < and > symbols: "Hello! I am Heteromorph, the one who contacted you to identify my Phlycticrioceras trinodosum specimen in May of this year, and I was wondering if you could help me identify another heteromorphic ammonite from the Upper Coniacian stage of the Austin Chalk. This specimen was found on March 23 of this year in a creek in Ellis county. It is, in fact, within half a mile of where I found the last specimen that I sent to you for identification. The stratigraphy of this area is the Atco member of the Austin Chalk, Prionocycloceras gabrielense zone. My problem is that even though it resembles P. trinodosum, there are differences that would make me reluctant to indenify it as such. To date, I have not found one like it. It is similar to P. trinodosum in that the whorl section is compressed, it has ventral tubercles, and it has an open planispiral shape. But it also has 3 key differences that make me think it is either a different species or it is very pathological. I list these below. First and foremost, the main difference is the lack of any ventrolateral tubercles, which are one of the defining characteristics of P. trinodosum. On both the specimen itself and its negative, it appears to be free of any ventrolateral tubercles. The only tubercles that I can see are the ventral tubercles which are something that P. trinodosum has as well. Second, the ribs are shaped differently than P. trinodosum. While P. trinodosum has rectiradiate ribs, this specimen has ribs which are rectiradiate until about half way up from the umbilicus, at which point it bends. Due to the fragmentary nature of this specimen, I have a hard time determining whether it bends abapically or adapically. Third, the ribs are more costate on this specimen than any of the twelve P. trinodosum specimens that I have found in the Austin Chalk. It has a rib index of 7, while the most costate specimen that I have found and know for sure is a P. trinodosum specimen only has a rib index of 5. While this is not unheard of for this species, with specimens of this species having rib indexes of up to 8 (Emerson et al. 1994), yet from my experience it is apparently very unusual for this part of the Austin Chalk. The closest thing that I have seen to my specimen is illustrated on Plate 11, fig 2 of Young, 1963 (as P. sp. cfr. douvillei), the similarity being the fact that they both have rib indexes of 7. After that, though, the similarity ends in that P. sp cfr. P. douvillei still has ventrolateral tubercles and rectiradiate ribs. I also found a very small P. trinodosum negative in the same creek just a few feet away. It has ventrolateral tubercles and a rib index of 4. The ribs are rectiradiate. A photo of it is not attached here. My specimen is 87mm long including its negative and has a whorl height of 34½mm. The oval whorl section is compressed like P. trinodosum. It is shown first in the attached photo DSCN5355. Aside from the specimen in question, for reference I have also attached photos of two P. trinodosum specimens that I have found. They are both from within 5 miles of the creek site, so they are on roughly the same stratigraphic level. What I am calling P1 is shown first in the attached photo DSCN5281 <F13> in comparison with the specimen in question. P1's negative is shown first in the attached photo DSCN5394 <22>. The positive is 69mm long when both pieces of it are measured together but 53mm when just measuring the largest piece. It has a whorl height of 31mm and a whorl breadth of 9mm. Rib index of 4. It was found within a quarter of a mile of the creek site. Because it is has just a slightly shorter whorl section to the specimen in question it is a good comparison piece. The specimen which I am calling P2 is shown in the attached photo DSCN5361 <F27>. It is only a negative but I am attaching a picture of it here because it is the specimen that I referenced earlier with a rib index of 5. It is 23mm long and has a whorl height of 15mm. It was found about 4-5 miles to the south-west of the creek site. For reference, here is a post I made about the P. trinodosum specimen that I sent you a picture of in May. I thank you very much for your help in advance. Sincerely, Heteromorph" I have given an alphanumerical designation to each picture for ease of reference. I guess it is probably kinda silly to have so many pictures that this is necessary. If this is stupid, than I extent my apologies to the Mods. I will patiently receive correction. Thank you to everyone in advance. F1 F2 F3 F4

  16. Coprolite?

    Hi, I'm new to the forum. I've always had a lay interest in paleontology and geology. Last week while playing golf in the Dallas-Fort Worth metroplex, I spotted this unusual lump in the rock landscape around one of the tee boxes. My first impression was coprolite with a chunk of undigested something jutting out, I circled it in red. I assume it was delivered with tons of rock from a Texas quarry and I have found other fossils in rock landscapes on a couple courses I play. I'd appreciate some more educated opinions. Thanks.
  17. Possible Bone Fragment

    Hi, looking to see if anyone can tell me if this is a bone fragment. I found this at a construction site near my home in Texas where dirt was recently dug up. It appears to have a fibrous structure and the ends are smooth and appear to have visible ends to fibers. Possibly a vertebrae fragment?
  18. I spent the morning screening in the Post Oak Creek of Sherman, Texas today. I found lots of small shark teeth...all different types. Tooth enamel from Mastodon/Mammoth and bits and pieces.
  19. Some time this November, I want to make a trip out to Post Oak Creek to hunt some fossils. I'm in Georgetown, TX, and I'm wondering if there are any good spots along the way that might be worth checking out. Might stop overnight in a hotel somewhere rather than trying to make the entire multiple-stop trip in a day. I'm hoping to find shark teeth, bones, echinoderms, and maybe some ammonites. Slabs with fossils inside would be really cool, too, maybe shale or something similar? Trouble is, I have bad knees, so I need areas that aren't too hard to walk through. I can't go clambering over boulders or on overly slippery stuff, and I can't climb up and down hills very much.
  20. My beautiful wife scheduled a three night stay at a cabin in a Thousand Trails campground near Lake Texoma. We were to arrive on Sunday and check out on Wednesday. So, I figured that, since I hadn't been fossil hunting in months, I would schedule a trip to central Texas to follow the Texoma trip. I set up a rendezvous point in Fairfield, Texas to meet my dad on that Wednesday, and head off toward Brownwood and Cisco, Texas. I figured that the fossil hunt would begin then. But that's not quite how things played out... My two oldest daughters and I met my wife and youngest daughter in Salado, Texas on Saturday, October 14th. They had left the previous morning to spend a day with my mother-in-law in Waco and Salado. We spent Saturday night in Salado and then parted ways with my mother-in-law on Sunday morning and headed toward Lake Texoma. As we drove through Waco, my wife asked if we wanted to take a detour. She had never been to Dinosaur Valley State Park in Glen Rose, Texas, and she thought the girls would enjoy seeing the dinosaur tracks in the Paluxy River. I got really excited. I hadn't been there since I was a kid, and at that time, the river was high and the tracks were not visible. So we adjusted our GPS to take us to Glen Rose. We pulled in and stopped off to get a map of the park. We then drove straight to the spot where Roland T. Bird made his first discovery. It was amazing. The water was low and gave us a clear view of the trackways in the river. Above you can see both the sauropod and theropod tracks, They are a little obscured by mud, but they are still very visible. We left the R.T. Bird site and went to another place called the Ballroom Track Site, where so many tracks go in so many directions, it was like the theropods were dancing. It was in slightly deeper water, but it was still beautiful! The rippling water was crystal clear and the girls couldn't help but get into the water, even as a cool front brought chilly winds down the river valley. My wife loved it. She told me that Dinosaur Valley State Park was our next camping destination. Before we left, we stopped off by the iconic Tyrannosaurus Rex and Apatosaurus models built for the 1964-65 World's Fair in New York. They were permanently installed at Dinosaur Valley in 1970 at the park's dedication. We left Dinosaur Valley and drove the rest of the way to our cabin at Lake Texoma, arriving just after dark. We settled in and tried to decide what we wanted to do the next day. It was Monday, and we figured there had to be something for the girls to do nearby. We quickly discovered that our options were limited. It had turned too cold for the pool at the campgrounds. The putt-putt at the campground was okay, but the girls quickly tired of it. And most of the other recreational equipment was not well kept, or available. So, we decided to leave the campground to find something for the girls to do. I had mentioned that I would like to check out the Permian site at Waurika, Oklahoma. It was only two hours away, and this was the closest I had ever been to the site. My wife was a bit miffed by the lack of things for the girls to do, so she said "Let's go." I jumped at the chance. I had done no research on the site, other than what I had read about it on TFF. I wish I had consulted the TFF experts before we left, because I had no idea of the best places to look. We focused mainly on the sandy floor and reddish rocks, and found nothing. When we returned to the cabin, I asked where we should have looked. Jesuslover340 informed me that the gray colored exposures were the places to find the best material. So, we came away empty handed, with only one major discovery. My wife wouldn't let me take it home, though... Continued in next post...
  21. Texas beach fossil id. Claw?

    While searching the beach for sea glass near Surfside Texas I came across this fossil. Maybe some sort of eagle claw core?
  22. Hey folks, That time of year again. Hopefully some portion of you Texans made your way to the Dallas Club's show Fossilmania this weekend. But for those of you further south check out Fossil Fest next weekend, November 4th & 5th in Round Rock, TX. This is the annual show, fundraiser and major educational outreach event of the Paleontological Society of Austin. The theme is Dinosaurs. But the show will feature displays of all sorts of fossils as well as dealers of all things paleo. See the attached flyer for details or go to our web site: austinpaleo.org I'll be there all day, both days. Erich Rose President, Paleontological Society of Austin Show Flier 2017.pdf
  23. North Texas Teeth

    I bought some Teeth from the man who found them outside Palo Duro Canyon, near Amarillo Texas. He wasn't sure what they were, so I thought it'd be best to post them here and ask for opinions on them. and just so you know, he didn't find them on the State park. They are from a ranch that backs up to the canyon. The second and third were in the same layer, and the first was in the layer above the others. Thank you!
  24. This heteromorphic species is characterized by an open plain spiral shape with rectiradiate ribs and 3 sets of tubercles, 2 sets of ventrolateral tubercles, and 1 set of ventral tubercles. The whorl section is compressed and does not have constrictions in United States specimens but does have constrictions in many European specimens. The distance between ribs is roughly the same as the width of a rib. As far as I know, there are only two species reported for this genus, with the other being Phlycticrioceras rude from the late Santonian of France. (Kennedy 1995). P. trinodosum is the only species reported in Texas. This particular specimen has a rib index of roughly 3 1/2, but some specimens of this species have been known to have a rib index of up to 8. (Emerson 1994). The highest rib index of a P. trinodosum specimen that I have found is 6, although I have one specimen which could be a P. trinodosum specimen that has a rib index of 7. It was broken in two when it separated from the rock shown in the last photo, with its outer whorl being shown in the 4th and 5th photos. The outer whorl is 53mm long, and at the top where the whorl height is measurable, it is 16mm. You can see in the photos of the main part of the specimen, the impression of where its outer whorl once was. The complete specimen would be about 65-70mm in diameter if its outer whorl was still connected. Mine shows a bit of pathology in some places, with two examples being the large gap in between two ribs shown in the 4th and 5th pictures, along with two ribs being very close to each other, which is shown in the 2nd picture. Here are a few references, with the hyperlinked references being underlined. The first 4 references that I have hyperlinked are open access, while the 5th is not open access but can be obtained online without having to request the text from the authors. The 6th reference has to do with the species Phlycticrioceras rude, the only other species in this genus. I have added additional links to sources with information about this paper due to the fact that it is not open access and must be requested. The 7th and 8th references are not open access and are not hyperlinked because I cannot find any way to obtain them online. The last hyperlink is an open access stratigraphic reference for the Austin Chalk and has no information about this genus.
