  1. A revisit to my Mini museum of prehistoric animals. Just added a nice metal model of a stegosaurus that MrsR got me for Christmas (she completed it, as she loves making them). All the fossils here are from Hell Creek except a small bit of dinosaur eggshell from Two Medicine Formation. A lot of the fossils are from winning the Grand Christmas Auction 2017 , it goes to show how much enjoyment I am still getting from this lot. Top floor Richardoestesia isosceles , Thescelosaurus tooth, Turtle bones , Montana Croc Teeth Mummified skin Hadrosaur species, from the Low
  2. Hi everyone, I wanted to get some opinions on this piece I found in Montana's Hell Creek formation this past summer. My initial thoughts were that it was a ceratopsid skull fragment. It was a fossil I was planning on selling, but before I do I wanted to rule out the possibility that it was a piece of ankylosaur osteoderm as I have significantly less material from that clade of dinosaurs. The dimensions are about 8 cm by 7 cm.
  3. So what is the difference between the lance fm and the hell creek fm? They both have the same dinosaur species and from what I can tell, other vertebrate species. The only difference that I can think of is that the lance fm is in Wyoming while the hell creek fm is in South Dakota, Montana, and North Dakota.

    Theropod Tooth Identification

    Here are two addition teeth from the Hell Creek Formation of Custer County, Montana. I believe they are from a juvenile T-rex. The first tooth is either a maxillary or dentary tooth. The second is a either a pre-maxillary or pre-dentary tooth. I would appreciate any thoughts on the taxonomy and jaw position. By the way I use these teeth for teaching Fossil Friday classes to kids. I apologize for the photos; for some reason I was having camera problems.

    Theropod tooth

    Hello- Some years ago I've bought this dinosaur tooth, labeled as theropod tooth; it comes from Carter County, South Dakota (Hell Creek Formation)- Its lenght is roughly 0,95" . I think it could be a tooth of a Nanotyrannus (or a juvenile Tyrannosaurus?), but I'd like to know the opinion of some expert about that- Many thanks in advance, Fabio

    Interesting Hell Creek Vertebra

    Hi everyone, I found this little, mostly complete vertebra in the Hell Creek formation of South Dakota in 2019. I don't really know what to make of it as it's very porous, and amphiplatyan (flat on both sides), although I'm not sure how much of that could be attributable to wear. I believe it's safe to cross of squamate (due to lack of concavity) and champsosaur (overall shape) off the list. While most of the crocodilian verebrae I have found in the hell creek have have a convex and concave end, I am aware that some can be found that are flat sided. The porosity of the bone makes me hopeful th
  7. Hey everybody! I wanted to make a thread sharing with you some of the smaller fossils in my collection, many of which I've photographed using my digital microscope. Some of these I've found in the field at microsites or channel deposits, while others I've found at home searching through matrix. I hope you enjoy! Our journey begins in Wyoming's Lance formation: A Pectinodon tooth my dad found in 2017. A tooth that was identified by other forum members as potentially Avisaurus, also found in 2017. A tooth I initially called Paronychodon, although the small &

    T. rex tooth

    Identification This is a classic T. rex tooth. It's clearly Tyrannosaurid by its robusticity, similar serration densities on each carina (mesial carina counted by the "roots" of the denticles as they are completely worn off), and chisel-shaped serrations. Those qualities with its locality and formation mean it must be the one and only. Notes The Crown Height Ratio (CHR) suggests a posterior position (it's short and stout). There's evidence of wear on the tip and mesial carina.

    Tyrannosaur tooth

    Identification Tyrannosaur teeth characteristically have similar serration densities on each carina, with chisel-shaped denticles. Though small, this tooth matches those qualities, and doesn't resemble other smaller theropods like Dromaeosaurids. Identified as Cf. T. rex based on its similarity to another, larger tooth in my collection. Notes This tooth is from a juvenile individual. Serration densities illustrated in the above photos. There is a slight pathology (bend) near the tip.

    Tyrannosaur

    From the album: Hell Creek / Lance Formations

    Tyrannosauridae (Nanotyrannus-morph) Hell Creek Fm., Powder River Co., MT, USA A classic Nanotyrannus Tyrannosaur tooth: compressed and blade-like. Exceptional preservation, with a minor wear facet near the tip on the lingual side (indicating it's from the left maxilla). I really like the color.

    Juvenile Tyrannosaur

    From the album: Hell Creek / Lance Formations

    Tyrannosauridae (Cf. Tyrannosaurus rex) Hell Creek Fm., Wibaux Co., MT, USA This minute tooth is indeed Tyrannosaur: the mc/dc serration densities are virtually identical, and the denticle shape is not like those of Dromaeosaurids. It also has a slight pathology near the tip.

    T. rex posterior

    From the album: Hell Creek / Lance Formations

    Tyrannosaurus rex Hell Creek Fm., Fallon Co., MT, USA The CHR suggests a posterior position for this somewhat beat-up T. rex tooth.

    Tyrannosaur tooth

    Identification Tyrannosaur teeth have similarly-sized serrations on each edge, and the serrations are chisel-shaped. This is a classic "Nano-morph" tooth being compressed and blade-like (which is the primitive condition of Tyrannosaurs). Notes This tooth has excellent preservation, with serrations crossing the tip, and clear enamel. There is a minor wear facet near the tip on the lingual side, indicating this is from the left maxilla.

    Dromaeosauridae

    From the album: Hell Creek / Lance Formations

    Dromaeosauridae (Cf. Acheroraptor temertyorum) Hell Creek Fm., Carter Co., MT, USA Acheroraptor's dentition is known incompletely, so it's possible this tooth is from Acheroraptor. Until more material is described, this tooth will remain indeterminate. There may be slight facets, but I'm not confident that's what I'm seeing.

    Acheroraptor temertyorum

    From the album: Hell Creek / Lance Formations

    Acheroraptor temertyorum Hell Creek Fm., Garfield Co., MT, USA A Velociraptorine tooth with the diagnostic longitudinal ridges Acheroraptor is known for. This tooth has some wear on the tip and root etching at the base. Art by Emily Willoughby

    Acheroraptor tooth

    Identification A. temertyorum is characterized by the typical Dromaeosaurid traits (compressed, recurved, differing mc/dc serration densities), and longitudinal ridges/facets on the crown face. Notes This tooth was found this past Summer ('21), and in the same county as the holotype specimen.
  18. Happy Christmas eve, Merry Christmas, Happy Holidays and a prosperous new year! It may be Christmas eve, but its also Friday, which means its a Fossil Friday. I missed las week due to being sick. Today's video offering is from the first day of a long, multi-day fossil exploration trip in South Dakota.

    Hell Creek Crocodylomorph Vertebra

    Anyone familiar enough with the Crocodylomorphs from the Hell Creek Formation to be able to help in determining a probable genus or species? I purchased this specimen and have been unable to find images or research papers with similar examples.

    Bizarre Hell Creek Denticle?

    Hi all. I know it's been a long time since I've posted anything on the forum, but now that I'm back from college I'm planning on being more active. Today I wanted to post this odd fossil I found this past summer at a Hell Creek formation microsite in eastern Montana. I've never seen anything quite like it before, but my guess is that it's some odd denticle from a cartilaginous fish of some variety OR alternatively it could just be an odd fish tooth (maybe pharyngeal?). It measures about 4 mm from base to tip and a little bit over 1 mm at its widest. Any input would be appreciated. -Noel

    Edmontosaurus tooth histology

    From the album: Dinosaurs

    Edmontosaurus annectens Hell Creek Fm., Harding Co., SD, USA Partial dental battery Hadrosaurs had the most histologically complex teeth of any animal, with six unique tissues. This allowed for differential wear, creating an ideal coarse surface for grinding plant matter. (Erickson et al. (2012))

    Hell creek theropod tooth

    I have this tooth that i believe to be a small nanotyrannus but i just want to get confirmation so let me know what you think everyone. Its from the Hell Creek Formation. Garfield Ct. Montana. Its CH is 11 mm Serration count: Distal 12 per 3 mm Mesial 15 per 3 mm The base of this tooth is beat up so its impossible to see if it would have had that rectangular pinch that is characteristic of nano teeth. There seems to be no twist of the mesial carinae In my opinion the serrations look peg like as seen in nano teeth.

    Hell Creek Ornithomimid metatarsal?

    This is from Hell Creek formation and 8 inches long. Seller named this 'Struthiomimus'. I compared it with some examples of ornithomimids from Hell Creek and I think this is a 3rd metatarsal of an ornithomimid.. If someone can verify? Thanks

    Help With Hell Creek Theropod Bone

    I’ve been going through some material that I collected this Summer in the Hell Creek of Southeastern Montana. I have this little theropod bone (measures approximately 14 centimeters). It is missing one end and has a little damage to the other. The bone is covered in a layer of siderite. I know that it is not much to go off of but am hoping someone might have an idea what it is. I can provide additional pictures if needed.
