  1. Hi all, Any thoughts on the ID of this claw? About 3 cm long, sold as ?dromaeosaur claw from Hell Creek, Slope County, ND. The phalanx was found in the same location but not articulated. I've chewed through the excellent "Identification of Claws/Unguals from the Hell Creek/Lance Formations" topic but can't quite fit it to anything!
  2. I came across a weird tooth online. The seller claims that it is an all-natural Tyrannosaurus rex tooth from the Hell Creek fm. (no more specifics than that), though it features very odd preservation. It is nearly pure white in color. As I have little experience in tooth identification and telling apart fakes, I would like to gauge everyone's opinions on whether or not this tooth is completely authentic and identified correctly. If I receive any more information about the specimen, I will make sure to list it here. *New info*: The seller has informed me that the tooth h
  3. Hello everyone I went on a commercial dino dig tour Summer 2022 of the Hell Creek formation in the Butte County, South Dakota area and found lots of bones and spitter teeth and had a great time. These two were in my unknown/unidentifiable pile and I've recently done some cleaning/prep to them and was requesting some help with possible IDs. The first item (on the left in most of the images) looks like a broken rooted ceratopsian/triceratops tooth to me with ridges and enamel showing. The second item (on the right in most of the images) looks a little like a scute w

    Interesting blue color near the base, and some feeding wear at the tip of this immature Tyrannosaurid tooth.

    Theropod Toe Bone

    Hey all, What do you think of this toe bone from Hell Creek? The seller marked it as Saurornithelestes with a "?" at the end. It's a tiny 0.5". What I thought might be diagnostic about it is the proximal end. I believe it has Toe 2 Digit 2 characteristics. But it also looks like the flatter top part of the proximal end (bottom part in this picture) may just be worn down or something--it doesn't look totally smooth. If you think there's anything to the Toe 2 Digit 2 hypothesis, then I assume it's theropod indet rather than Saurornithelestes--or is there a case for young
  6. 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
  7. (Note: I don't know why half of this is in bold, I wrote this in a google doc first and copy pasted it to here, and it defaults to bold without the ability to undo it. This tends to fluctuate. Easy to see though!) "Dinosaurs are overrated", Mike teased to me. We were sitting together at the flooded dig site of our mosasaur in the early morning hours, having just finished a jam-packed but enjoyable conversation about his research and other matters related to paleo. Naturally, dinosaurs were brought up, as our schedule had to work around my upcoming internship to the Hell Creek forma

    Bizarre Hell Creek teeth

    Hi all, These two teeth came from the same seller and were put up for sale at the same time. They're so odd, that I thought it might be helpful to post them together since, if they come from the same animal, perhaps they provide more information as a pair than either would alone. Ricardo premax? Pterosaur? Acheroraptor? From the Hell Creek formation in Garfield, Montana CH: About 10mm (both) CBL: Tricky enough that I didn't measure, but can try if needed CBW: Tricky enough that I didn't measure, but can try if needed Mesial Serration Density: about 1
  9. I've had these crocodilian teeth from Niobrara County in the Lance Formation for a while now, but I'm not sure how if its possible to ID them beyond "Crocodilian tooth." I've generally heard that the "sharp" morphology are Borealosuchus teeth and the short bulbous teeth are Brachychampsa. Is that a safe rule to follow? I've also noticed that there are some slight differences in the teeth I have (hopefully the pics make it visibile). They're small, but the two on the lower left have noticeable raised striations (not sure what to call it). However, the one on the lower right and on the top are s
  10. Good evening to all my paleo peers! Tonight I’d like to share with you a selection of some of my favorite fossils found this year. I was lucky enough to spend three weeks in Montana over the summer, along with a few other fossil hunting opportunities here and there. As we hop into the New Year I'll kick things off aptly... Frog Radioulna-Judith River formation, Montana One of my all time best single fossil hunting days was spent in late June on a microsite in the Judith River badlands of northern Montana. Among the teeth of crocs, hadrosaurs and dromaeosaurs was this absolutely tiny

    Tyrannosaurus Rex Tooth?

    Hi, according to the seller this is a 2 inch Tyrannosaurus Rex tooth from the Hell Creek Formation, Harding County, South Dakota. Really interested in your opinions, thanks.
  12. This partial crown was collected from the Hell Creek Formation, Garfield County, Montana. I acquired it for a teaching collection because I think it tells a story. The basal section shows almost an inch in diameter. Is this a Trex tooth? The tooth shows antemortem enamel spalling and wear as described by Schupert and Ungar, 2005. It feels as though that the tooth was broken as a result of probably bone crushing and was worn smooth with continued feeding, then shed some time later. I would appreciate your thoughts.

    Ankylosaurus tooth

    Identification Teeth of Nodosaurids are often confused for those of their rarer relatives, the Ankylosaurids, namely the archetypical Ankylosaurian, Ankylosaurus. (Most) teeth of Ankylosaurus are taller than they are wide, are generally conical in shape with one side flatter than the other, have large denticles on the anterior and posterior edges (6-8 anterior, 5-7 posterior), and have swollen/bulbous bases. Tooth wear is normally on the crown face, compared to wear on the tip (apex) as in Nodosaurids.1,2 Comments This tooth is partially rooted; the root is cylindrical and holl

    Pectinodon tooth

    Identification Troodontid teeth may be identified by their exaggerated, triangular, apically directed posterior denticles1. Pectinodon bakkeri is the only Troodontid species currently named from Lancian strata; its teeth are on average smaller and more gracile than those of its cousin, Troodon. Comments Pectinodon (meaning "comb-tooth")1 is a tooth taxon, since no remains attributable to the genus beyond teeth have been found. Pectinodon seems to be a rare member of the Hell Creek fauna, with their teeth being fairly uncommon. It was a small theropod, with teeth that couldn't ha

    Nanotyrannus or Dakotaraptor?

    Hey all, What do you think of this one? Hell Creek formation, Powder River co, Montana CH: 10.9mm CBL: 6.6mm CBW: 2.9mm Mesial serration density: about 4.8/mm Distal serration density: about 4.0/mm Distal serrations are pretty worn except those near the tip, which look fairly chisel, but have an apical hook(?) Thanks!

    Troodon premax?

    Hope everyone is having a nice weekend. I'm thinking this 6mm tooth (perhaps 7mm, if not for wear) from the Hell Creek formation of Garfield co, Montana is a Troodon premax. What do you think?
  18. I recently had the opportunity to purchase some jacketed fossils from a ranch in Garfield County, Montana in the hell creek formation. I bought 2 jackets, one with several small ribs present that I am currently working on. Another containing a single bone that I think is a hadrosaur pubis. One thing that surprised me was the wealth of smaller bits of bone present in the jacket I'm sure this is an amazing microsite I would love to see first hand. There were some really small bones that I don't think are identifiable but regardless very cool. This one with a r

    One more small claw from Hell Creek

    Hi @Troodon, I've got one more for you. It's from the Hell Creek formation, Power River co, Montana. It's 7/8" long, but might have been more like 1.5" long if complete, since the point looks like it'd get very slender and long. Potentially with left blood groove swinging up around the top. (The blood grooves are very asymmetrical in trajectory.) Thanks!

    Tyrannosaurid premaxillary tooth

    "That some of these teeth are mammalian incisors there can be but little doubt..." - O. C. Marsh1 This kind of incisor-like ("incisiform") tooth was originally thought to have belonged to a large, Cretaceous mammal. Later discoveries revealed that these teeth were actually the front teeth ("premaxillary teeth") of Tyrannosaurs - and are now known as a hallmark of their clade, Tyrannosauroidea (along with fused nasals). Closely-spaced, parallel grooves on bones suggest that Tyrannosaurs used these teeth to selectively scrape meat from bone2. Identification Tyrannosaurid premaxil

    Ankylosaurus tooth

    From the album: Hell Creek / Lance Formations

    One of my favorites as a kid - the archetypical Ankylosaurian - Ankylosaurus. Ankylosaurus teeth appear to be fairly uncommon in Hell Creek - some paleontologists have suggested that Ankylosaurus may have lived in the highlands or nearer the coast of Laramidia. Most "Ankylosaurus" teeth you see for sale are actually Nodosaurid (cf. Denversaurus), for whatever reason, they seem to be far more common. Ankylosaurus teeth also often have wear facets, as this one does. The denticles give their teeth a "leaf-like" appearance. Given their shorter stature, Ankylosaurians probably were low-browsers.
