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.

Triceratops horridus (or prorsus) (Marsh, 1889 /1890) Late Cretaceous, c. 67 Ma Hell Creek Formation, Powder River Co., Montana After acquiring a gorgeous T. rex tooth, I could not resist the opportunity of acquiring a tooth of its likely prey - Triceratops. I’m aware of the difficulty in identifying ceratopsian teeth and the impossibility of distinguishing between T. horridus and T. prorus. As Triceratops is the most commonly encountered genus within the HCF, this is labelled as being Triceratops horridus or prorus in my collection. I understand that the locality is known for T. prorus so it may well be that this is T. prorus. I love this specimen for it still having the root - so unlikely to be a shed tooth.

Hello everyone! I have been going through some of my older fossils I collected from the Hell Creek Fm. near Glendive, Montana a few years back and found these three teeth. Anyone know what they may be? I can provide any additional photos or info necessary. Thanks!

Hello dear all, after a long and stressful time I finally was able to acquire some new teeth and to try to figure out (to my best ;-)) what they are or might be… After reading these really helpful guides on the Hell Creek teeth I tend to label this tooth as Acheroraptor temertyorum The serration count is between 17 and 21 (actually i counted 17, 19 and 21, depending on the location +-1 inaccuracy)on a length of 5mm The length (CBL) is approx. 1.1 cm According to the seller it is from the Hell Creek Fm, Montana. Would you agree on Acheroraptor?

Recently acquired this beautiful T. rex tooth, just over 5cm / 2” length. Such teeth are typically dark brown / mahogany coloured but this specimen appears to have escaped the usual staining. The location of find (Hell Creek Fmn, nr. Mosby, Garfield Co., Montana, USA), basal rectangular cross section and thicker enamel supports identification that this is a Tyrannosaurus rex maxillary tooth. The fact that the whitish / pale colouration is consistent throughout, absence of pitting / “dried out” appearance / absence of splintering would seem to preclude sun-bleaching.

Nothing too crazy in the collection yet just some theropod teeth mostly from HC MT. ID'd (when I bought them) as a nano, a Acheroraptor, Dromaeosaurs and a little bitty tooth I'm not sure of. I have a few ceratopsian bones and teeth, amber and such. There's a few Spino teeth and some low quality Carchardontosaurus teeth I want to get replaced with better ones.

I don't think I've seen dinosaur scales with this shape. Could these be fish scales instead? Also, I wouldn't think skin impressions would be common enough to show up for sale.

Hello, Wondering if this is T.rex? Or Nano? It measures 1.25 inches and is said to be from the Hell Creek Fm. of South Dakota, no county unfortunately. The base doesn't seem 100% complete but from what is there I don't think is has the expected "pinch" of a Nano. Thoughts? Thanks.

I obtained this tooth on a dig back in early June close to Jordan, Montana and was immediately told it was definitely a raptor tooth and was content with that. But more recently I’ve gotten curious and done some reading to try to figure out what exactly it was. From what I’ve read and seen online, it is pretty much a token Acheroraptor tooth with the very apparent ridges and larger serrations on one side while the other has small or none, but I wanted to double check with someone more familiar with the teeth to make sure. I’ll post any pictures requested, thanks! (also, please don’t tell me this tooth is fake or super restored because it is 100% not. I discovered and prepared this tooth myself and the only damage its had is a break that was glued back together near the root. It feels like this should be common sense after saying I found this myself in the post already, but I've already had people tell me I'm posting fake fossils [and arrowheads, but thats a different story])

Is this a nanoryrannus dakotaraptor or another dromaeosaur tooth?
Fossil Maniac posted a topic in Fossil ID
Hello! I found this tooth online it is labeled as a “dromaeosaur” but I would like to identify it further. I was thinking it could most likely be a nanotyrannus or a dakotaraptor. Unfortunately the seller didn’t provide a locality, all I know is that it is from the hell creek formation in Montana. Thank you for any help.

How can you tell a difference between a Juvenile T.rex tooth and a Nanotyrannus tooth?

Hi, I recently got this cretaceous mammal tooth from the Hell Creek formation, and I was wondering if you may help me find the scientific name of the species that it belonged to. I've done some research and learned that it was the premolar of a Multituberculate mammal. This order of mammals was diverse and there were many species. I think it might be one of the members of the Genus, Mesodma, Yet I could be wrong. I tried to narrow it down to the exact species, yet there are few examples to help me pinpoint to a certain Id. This tiny tooth is from Garfield County, Montana. it is from the late cretaceous period (~67 - 66 Ma). It measures approximately at 3/16" long by 3/16" wide (5 mm x 5 mm). It is thin and blade-like towards the top of the crown. The enamel has a grooved texture on the surface. The overall shape of crown resembles a saw blade. Hopefully I would be able to id. this specimen and to learn more about it. Feel free to ask me for better images.

This is the only described Nodosaurid in the Hell Creek Formation at the moment. New discoveries may make it impossible to bring this tooth down to genus and species.
