    Found object

  2. I am going fossil hunting on some property I have in South Dakota this weekend. The Firesteel creek runs through it and I have found quite a few bison bones on quick 30 minute trips. This time I am spending 2 days along 1.5 miles of creek to look deeper If anyone has pro tips feel free to share

    Hell creek rib

    This unknown rib was recovered a couple months ago from a private ranch near Faith, SD. I haven't had time to start work on it until a couple days ago. I'm keeping track of my hours on this one just out of curiosity. I never tracked the work on any previous prep projects. So this was found partially exposed with a number of pieces found as float at the bottom of the hill. Everything surface was collected, then the rest of the rib was jacketed to remove. It took me 3 hours to uncover and remove it from the jacket, and then 5 hours separate and clean the pieces of the first section. 12 hours total to clean 3 sections, and then another 3 hours for the micro cleaning and reassembly of those sections. Its only going to get harder, because much of the rest of it looks to be heavily crushed and displaced. It also looks like there is a healed fracture to this rib, but of course, the modern break goes through the remodelled bone.

    Leptictis jaw

    I recently saw a 1.2cm long Oligocene mammal jaw from South Dakota, judging by the coloration of the specimen from the Brule Formation, up for sale. The jaw is referred to as Leptictis haydeni, but the description states it to be from a primitive weasel. Moreover, I have never seen any Leptictis material for sale and the dentition looks as much like that of the relatively similarly named but much more common Leptomeryx than any leptictid. Thanks in advance for any guidance Othniel

    Reptile head

    This appears to me to be the severed head of a reptile. It is slightly deformed post mortem. Scales or osteoderms are faintly visible in a few places. There is a branched structure on the underside that looks very much like a blood vessel. There are circular shapes at the end where the head was severed from the body, suggesting a spine and torn ends of major vessels. It was found in Deuel County, South Dakota, USA. The geology of the area is basically glacial deposits. No strata or matrix evidence is possible. It measures 60 mm x 30 mm x 35 mm and weighs 80 g. Is this a reptile head, or am I suffering from pareidolia?

    No. 1 for future reference. One of the largest and most intact Scaphites I found.
  10. Hello everyone. I was flipping channels last night between an old western and other channels when I came across this show on the public t.v. channel. (mpt.org) It caught my attention because they were talking about fossils. I wasn't aware of the title, yet. I wonder if anyone saw it also. If not, the show followed the discovery of "the largest Triceratops" ever found. Big John. In the Badlands of S. Dakota. They interviewed the gentleman who discovered and, extracted it. I'm sure a lot of you know who this is. Then, the show follows Big John's journey to Italy, after it was purchased from the discoverer, where it was prepped. It was there that they determined how big "Big John" really is. Guinness Book of World Records was approached by the curator to classify it as the largest Triceratops. And, then the show follows the media firestorm created by Big John as it heads to an auction in France where it was sold for an unreal amount of money. Fortunately, it was purchased by an American and brought back here. The show reveals the purchaser at the end, and, where Big John is currently displayed. In a children's museum in Tampa. I'm sure this could be a sore subject for the professional paleo people on this site. But, I'm just curious to know everyone's thoughts. I feel, in a way, the story had a happy ending in that Big John is here and not in someone's living room on the other side of the world. I have other thoughts, but, will wait to see how this conversation develops. Thanks for reading.
  11. Went on a dig as a kid with a group called " Paleo Prospector's" and this was some of the stuff found as well as my last post. Some was identified on the spot but I have my doubts on some. First 2 was labeled "raptor digit" 3-4 labeled turtle jaw 5-6 triceratops spitter 7 freshwater shark vertebrae
  12. Need help identifying some fossils found during a trip I took with my family years ago. I know it was a paleontology dig out at Hell Creek Formation in South Dakota.

    ID REQUEST - Possible fossil bone

    Folks, Attached are 4 photos depicting a an unknown fossil: Two horizontal, one each of both ends. The specimen we think is from South Dakota and is Cretaceous. Dimensions are 2" x 4", with a weight of 1.2 lbs. This high weight may be due to pre-mineralization or other external factors. If is is a bone, it resembles a metatarsal. I would appreciate any ID feedback from the group. Thanks .. Rick Strapple

    Dinosaur rib

    I'm interested in this rib end from the Hell Creek formation of South Dakota and was wondering if there was any way to identify the species. I've compared it to several large species that were native to the area and in my opinion, this piece compares very well with tyrannosaurus. Then again I'm no expert and would very much appreciate a second opinion. I've included examples of ribs from each species I compared it to.

    Tyrannosaurus rex tooth

    From the album: Dinosaur Teeth

    Tyrannosaurus rex tooth from Hell Creek Formation, South Dakota.
  16. Tyrannosaurus rex (Osborn, 1905) Late Cretaceous, c. 67 Ma Hell Creek Formation, Isabel, Dewey Co., South Dakota, USA. It has been a dream since childhood to own a Tyrannosaurus rex tooth and my dream came true with this recent acquisition of a gorgeous T. rex 1.5” dentary tooth.
  17. This is another mystery item from the collection I acquired this Spring that I need more info on. The Baculite segment is labeled "gravel pit, Wasta, SD". The scaphites had no label so it is not clear if they belong with the bac or not, and the lady who gave them to me could not remember. There was the possibility (sounded like a complete guess) that they could from the same place as the baculite. Is that possible? The preservation does not seem to match but of course we've all seen different preservation styles come from the same location before. Does anyone know of that location, or otherwise have a suggestion of a) the ID for either the scaphites or the baculite segment, b) the location of origin for the scaphs, or c) the formation for either? Last pic under shadow shows the pearly color of the scaphs better. (1st pic under indoor lighting)

    Merycoidodontid Jaw Fragment

    This is a merycoidodontid jaw fragment from the Oligocene of South Dakota, but it hasn't been identified to genus/species level. The specimen is 24.5mm long and 32mm across. Thanks in advance for any proposed IDs Othniel Just to clarify you may have seen a fossil ID thread with similar pictures to this, also started by myself. However, as suggested by FossilDude19, I will be splitting them up so as to not restrict answers. If anyone could explain how I get rid of the old thread, that would be much appreciated as well.
  19. Hello everyone this is my first post on the fossil forum.I’m 16 year old girl with autisum that loves fossils and I need help Identifying a fossil I got at a fossil/gemstone shop in South Dakota.I think it may be the rhino species Hyracodon.I also have a another fossil I got from the same place and I think it may be fossil horse or oredont tooth.So I would really appreciate it if someone can help me identify these.please and thank you.
  20. During a recent visit on April 25th, 2023 to the Field Museum, one of the best museums in all of Chicago, I stopped by the new Native Truths: Our Voices, Our Stories exhibit. I must say, it's a pretty good exhibit (perhaps my third favorite exhibit, only behind the Hall of Conservation and (one of the Museums's best and most accurate exhibits) the Evolving Planet)!!! The Native Truths exhibit shows and talks about the struggles and triumphs of the many Native American Nations from their origins to the modern day in blunt and extremely accurate ways. But there was one part of the exhibit that somewhat surprised me. It's a display case with several Late Cretaceous fossils from North and South Dakota alongside an interactive pad that talked about how the specimens were originally held by the Standing Rock Institute of Natural History. I'd never heard of the Standing Rock Institute of Natural History before. I was immediately intrigued but saddened to hear it closed due to lack of funding. I researched it a bit more and discovered it's located in Fort Yates, North Dakota. It's website is also apparently still up. https://srinstituteofnaturalhistory.com The museum was located in the heart of the Standing Rocks Reservation, home to the Hunkpapa, Sihasapa, Ihanktonwona, and Pabaksa bands of the Great Sioux Native American Nation. The Reservation itself is the result of the U.S. Government's continual and illicit breaking of Treaties with the regions Native American Tribes in order to grab as much of regions gold as possible in the 1870s-1890s. This is a very simplified explanation as to what happened as whole pages could be filled with with confirmed accounts of truly barbaric atrocities sections of the U.S. Government and the U.S. army inflicted on these Native American Nations at this period in time...something likely too graphic and horrifying to talk about on the forum. But I encourage you all to research it yourselves for if we don't learn or heed the lessons from history, we are doomed to repeat it. Anyways, from what could gather, the museum wasn't particularly large but still impressive in its own right. Opening in 2007, the Standing Rock Institute of Natural History is apparently the first tribal run museum to have it's own Paleontology Code of Ethics and at its height had 10,000 Paleontological specimens. I'm very sad to hear it closed due to lack of funding.

    Tiny theropod tooth

    Any idea what this little tooth could be from? It was found in the Hell Creek formation outside of Faith, South Dakota. It has no serrations and the seller says it may be a juvenile richardoestesia.

    Theropod

    Been trying to identify this digit for a while. Recieved it as a gift from a friend. I can't remember exactly if it was from Wyoming or Montana, but it was one of the two.

    Bathornis?

    This was labeled as a Phorusrhacid, possibly Bathornis and was found in the Brule Formation of South Dakota. Is that accurate?
