Identification Tyrannosaurid Teeth From North America
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- 85 replies

Number of Tyrannosauridae genera in Western and Eastern North America during the Maastrichtian Cretaceous
Joseph Fossil posted a topic in General Fossil Discussion
Along with an interest in Pennsylvanian fish diversity, I've also had an interest (like many others studying Paleontology) in the diversity of Dinosaur genera during the Cretaceous era (particularly the Theropod diversity in North America during the Maastrichtian period 72.1-66 Million years ago). Compared to the preceding Campanian period (83.6-72.1 Million years ago), I've noticed there is a slightly less number of known Tyannosauridae genera in Western North America (at the time a separate continent known as Laramidia). I've come up with a list of confirmed known and possible Tyrannosaurida -
The two most prominent hypothesizes on the direct evolutionary origin of perhaps the most famous Theropod Dinosaur from the fossil record, Tyrannosaurus Rex (Tyrannosauridae, Late Cretaceous (68-66 Million Years ago)) are what I call the Laramidia and Asian Origins. The Laramidia origin (named after the region of the Western North America which was a separate Continent during most of the Late Cretaceous and home to a vast amount of dinosaurs including Tyrannosaurus rex) hypothesizes that Tyrannosaurus rex is the direct descendent of and evolved from slightly older North American T

Hi all, Wondering if this checks out as Albertosaurus. From the Horseshoe Canyon formation in Drumheller, Alberta, Canada CH: 33.1mm CBL: 16.1mm CBW: 10.5mm Mesial Serration Density: 4/mm Distal Serration Density: 3/mm

Hello again--thanks so much for all the help lately! Is it likely that this is from Albertosaurus and not another tyrannosaurid if all we know about it is that it's from Alberta, CA? What additional info is needed to make such a call?

This is an Albertosaurus tooth in the matrix. Below this matrix is a hadrosaurs rib, the fossils comes from Drumheller ,Alberta, Canada There are special patterns on the enamel. Any insight on this would be greatly appreciated.

Hello I am looking for help to identify these two teeth. I was told that they are T. rex but I feel either one of both are Albertosaurus but not 100% sure how to tell. I have included many photos and measurements. Both teeth are from the Hell Creek Formation. The first tooth and the shorter one is measures 2" long by 1" wide The second and longer tooth measures 2 1/4" long by .3/4" wide. Any information would be appreciated.

Hi there everyone! I’ve recently been looking for a tyrannosaur tooth to add to my collection and I came in contact with a very nice seller who’s in possession of two theropod teeth. The main tooth I have questions about is the “Albertosaurus” tooth as that one seems to be the one which would be easiest to ID. I was wondering if it was truly an Albertosaurus tooth or if there was any other identification that could be given to it. The other tooth, the “Tyrannosaurus Rex” tooth, only has one picture and seems to be in two pieces. I’m aware that the single pic

Hey! These are just a few of the bones I found recently which were all found near each other in horseshoe canyon AB. I found what I believe to be albertosaurus teeth and a piece of a hadrosaur jaw as well with them which makes me assume they are from one of those two species. However, I need help identifying which species each one might be from and what part of the dinosaur they are. If you need measurements I'm happy to post pics next to a ruler!

Hey! Both of these teeth were found in the horseshoe canyon in the same place. I was thinking Albertosaurus but I don't know(They are serrated if you couldn't tell from the photos). Any ideas? (sorry for the low quality images)

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 seen multiple hell creek fm teeth for sale labelled as “Albertosaurus”, though I’m pretty sure I’ve read that the only way to confirm it’s Albertosaurus is for it to be found around the Drumheller area, specifically horseshoe canyon. Is this true, making the teeth simply indeterminate tyrannosaurids or are the fossils of this animal found elsewhere? Thanks.

Hello. I found this 7.5 cm Albertosaurus tooth in the Bleriot Ferry area of the Horseshoe Canyon Formation last month. Based on the wear mark on the end, whereabouts would the tooth be placed within the mouth? (top or bottom?). Is it possible to tell?

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

Hi I found this and am wondering is this a new species of tyrannosaur I don’t think it’s albertosaurus libratus because it is in a collection with gorgosaurus libratus and albertosaurus sarcophagcus so if it was albertosaurus libratus there would not be any specimens named gorgosaurus libratus there are other specimens then just this tooth too any information? Thanks.

Hello!!! I have been offered this tooth. The seller says it is from Albertosaurus and comes from Montana. Without restoration, they have only used glue. What do you think? Thank you very much and sorry for the quality of the photos but the seller does not know how to make them better ...

This one inch robust tooth came out of Hell Creek Montana and labeled as Albertosaurus. Does that appear correct? Can one tell the difference from other therapods in the region? Thank you in advance

Hello! Over the weekend I made some new labels for my fossil collection and I was wondering what everyone thought of them. I have QR codes which link to the corresponding "prehistoric-wildlife.com" species page for more info, and I added in some basic I.D. info to the cards to not crowd them. I also attached numbers to the labels and the fossils, so that I don't need to keep the labels directly next to the fossils. Would love to know what you think, and if anyone wants more information/the template I created. Thanks! P.S. Two of my I.D.s I'm still not 100% on (deltadromeus and Pec

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.

Albertosaurus tooth for sale
DatFossilBoy posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone. I saw this nice Albertosaurus tooth fragment online being sold for relatively cheap. I thought it had nice size,serrations and tip. It is from the Judith formation in Montana. Do you think it is worth considering? Or do you think I should keep my money. If I could get it a bit repaired and nicely reglue the fragments,It could be quite neat I think. It would be my first Tyrannosaurid in my collection (and my only for a long time). What do you think? Here are the 3 pictures I have. Thanks alot,Regards -
I'm still on the fence about if Nanotyannus l. is a valid genus or not. I used to be firmly on the "Juvenile T.rex" side with Carr but some arguments such as the odd limb proportions on "Bloody Mary", tooth counts in actual juvenile Tyrannosaurus like "Baby Bob", and there being two "types" of Tyrannosaurid teeth in Hell Creek with overlapping sizes but very different shapes which don't all seem to be cases of it being teeth from different parts of the mouth, have shifted me to being open to both sides. I suppose it does make ecological sense for there to be a medium-size carnivore in the same
