Identification Tyrannosaurid Teeth From Canada & United States
Troodon posted a topic in General Fossil Discussion
Updated Nov 25, 2022 Collectors, online sellers and some dealers periodically ask me to help them in the identification of tyrannosaur type teeth. So I thought I would put together a guide from Western North America (US/Canada) to help in identification. The following is the current understanding of those Tyrannosaurids described/known with the stratigraphic unit where they are found. If I missed any let me know. Albertosaurus sarcophagus : Horseshoe Canyon Formation cf Albertosaurus indet: Wapiti Formation Gorgosaurus libratu- 86 replies

ID help: Judith River Formation Tyrannosaur tooth identification
Praefectus posted a topic in Fossil ID
Hello. I was wondering if anyone could help me identify this tyrannosaur tooth I recently added to my collection. It is said to be from the Judith River formation in North-Central Montana. Unfortunately, I don't have the county it came from. The tooth has the following measurements. Thanks for your help. CH = 40 mm CWB = 10 mm CBL = 16 mm MC = 18 denticles/5 mm DC = 14 denticles/5 mm DSDI = 1.29- 14 replies

Hello all, I need some help ID'ing these two tyrannosaur teeth from the Two Medicine Formation in Montana. Does anyone know how to tell the difference between Gorgosaurus and Daspletosaurus teeth based on this size? Thanks for any help.

Dinosaur tooth. Gorgosaur? Nanotyrannus? T-rex?
Josesaurus rex posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello again. I saw this tooth on the internet, I don't know what dinosaur it could be from. In the description of the publication it does not say anything, only that it is from the theropod and from the United States. I suspect it is from a tyrannosaurid, but which one? I don't know. Gorgosaurus? or T rex? There is no further information on the origin or training where it was obtained. What do you think it could be? I know that with so little data not much can be done, but I would like to know the opinions or suggestions that you have on this ma -
I have here five Therapod teeth from the Judith River Formation of Hill County, Montana. Four are partials, and one is a small and complete. They were identified as Tyrannosaurs, but I'm wondering if that's accurate, and if it's possible to narrow them down further. It's probably a long shot, but I felt it would be useful to ask here where there are many more knowledgeable about theropods than I am. I've offered different angles, sizes, and serration counts. Thank you, Bellamy

Daspletosaurus tooth (?)
TheItalianPaleo posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone, So I came across a tooth that says this tooth comes from a carnivore (Gorgosaur/Daspletosaur), is 3.81 cm in length. The seller is a Daspletosaurus, but you know, before buying anything I have to ask your opinion. It was found in the Two Medicine Formation. There was a debate as to whether it was either a Gorgosaurus or a Daspletosaurus. So the questions are: Is it a Daspletosaurus or a Gorgosaurus? In what condition it is?- 9 replies

I bought this tyrannosaur tooth a while back and it says it’s a albertosaurus, gorgosaurus, or daspletosaurus. Is there anyway to narrow it down any further? It says it was found in the Judith river formation of eastern Montana and it measures just over an inch. Any and all help is appreciated.

I just got this and it will be arriving soon, It will be my largest dinosaur tooth yet once It comes. It’s a Tyrannosaur indet for now and it’s from the Judith River Formation. Just wanted to share this. I wanted to share more information compared to my other topic.

Hi I have a question, I went back since I had some time and re measured my Tyrannosaur tooth denticles. But there both the same size, the Mesial and Distal are both 6. And the DSDI is 1, what would this mean? Thank you!! @Omnomosaurus, @Troodon

Hi I decided to make this since the new Tyrannosaur from Alberta’s Foremost Formation, Thanatotheristes deerootorum has just been named and described. Enjoy!! Tyrannosaur bearing Formations in Canada: Formations in Alberta but most of the Formations on my list are I Alberta anyway. Horseshoe Canyon Formation 74-68 million years ago, Alberta: Albertosaurus sarcophagus, possibly Daspletosaurus sp. but no compelling evidence so far. Oldman Formation 78.2-77 million years ago, Alberta: Daspletosaurus torosus, Gorgosaurus sp. Foremost

Wow its already the 17 of January where has the year gone? Well always time for some cool photos of some great fossils to keep us going Its not unheard of to find dinosaur bite marks on a fossil. This Triceratops pelvis on display at Museum of the Rockies has Tyrannosaurus bite marks on it (red arrows) One way to identify a theropod bone is to see if they are hollow, another way is to look at their vertebra most are pneumatized, have a honeycomb structure. Here is an example of a T rex vertebra You hear alot about the Nanot

A Walk Through Dinosaur Provincial Park, Alberta, Canada - 22/7/18
Paleoworld-101 posted a topic in Fossil Hunting Trips
This report is a bit late, but better late than never! During late July through to mid August 2018 i was on a research trip to study a new Canadian dinosaur footprint site for my Masters degree project. I am based in Australia, and this was the first time i had been to Canada! So of course i had to make the most of it and pay a visit to the world renowned Dinosaur Provincial Park in southern Alberta, arguably the richest site in the world for dinosaur fossils. The park is the best exposure of the Dinosaur Park Formation (which it is now named after), which dates to about 76.5 million years ago- 17 replies

The Royal Terrell Museum shared a super specimen they collected and prepared of a Gorgosaurus that is the most complete juvenile tyrannosaur specimen discovered in Canada (and possibly even in North America). The Museum of the Rockies gave the skull of Big Al, MOR 693, a much needed acetone bath, new coat of vinac & a new conservation cradle before going back on exhibit. Big Al is one of the most complete Allosaurus specimens in the world! The most complete sauropod specimen known is CM 11338, a juvie Camarasaurus lentus. Courtesy: Saur

Hello all, Recently acquired 2 teeth, found and sold together, that I would love some insight and second opinions on. Both teeth are described as Tyrannosaurid Indet, from the Judith River Formation. The seller described that he purchased them both together from the harvester, but due to the fact he was not the original collector, the information is isolated to the above information. Smaller tooth is 15/16" long, dark chocolate color, and 1/4" wide. Serrations are present on front and rear edges, with serrations starting midway on the front edge.

On my birthday I got a juvenile gorgosaur tooth didn’t look special other then the colour but then I started to check it out and study it and instead of serrations there were small holes so I came up with a theory how juvenile tyrannosaurs didn’t have serrations until they got older yet I still need more proof to back up my theory but I found it interesting it was collected on a ranch in the Judith River formation not to far from the Canadian border it is 75 million years old here are some photos of it.
