Hi, I recently found one of the books I got not too long a go about dinosaurs of Alberta, and in the book there was a study that shows you can distinguish Tyrannosaur teeth from Alberta and Montana. Here’s the page. The study was done by Dr. Angelica Torices.

Hi I'm just wondering in some cases can the root of a tyrannosaur tooth stick out causing the tyrannosaur tooth to be bigger and if so will the tooth be fine and still be able to be used by the tyrannosaur @Troodon THANKS!!

Hello everyone, after having seen many pictures of "nanotyrannus" and t rex teeth i have some questions. The first one being, how can paleontologists distinguish nano teeth from rex teeth and also sell them for a different price when the current theory is that they are the same dinosaur, also in many cases I have seen nano teeth with the same size as t rex teeth differentiated, so if they are the same dinosaur how can this be possible? Thank you for your time.

Hi guys, I have recently acquired this tooth. It was sold as a Tyrannosauridae indet tooth from Bissekty Formation. I thought it could be Timurlengia, but i was not sure. From what I read, not much Timurlengia material has been found.. The tooth is about 2 inch long, and it is a little bit worn out. Its serrations are quite small. The serration density is about 12 denticles per 5mm. I am hoping someone can confirm the species for me?

Hi is this a tyrannosaur tooth from the horseshoe canyon formation? It’s 1.2cm Thanks!!

I bought this tooth a few moths ago, and I’ve been wondering if it was from the front of the mouth or not. It’s a tyrannosaur Indet tooth from the Judith river formation, and it’s about 1.25 inches long. It was listed as a front maxillary tooth, but I wasn’t sure if there are any other types of teeth besides the premax teeth the front teeth on the bottom (I think they’re called dentary teeth?)that have serrations on the sides of the tooth instead of the front and back.

New to collecting and this site, thought I’d debut my small collection in my first post. Any comments or tips would be appreciated.

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. Larger tooth is missing the front edge, appears sheared. Length is 1 1/8", width 5/16". Serrations present cleanly on rear edge, but again completely sheared from front edge. Color also deeper chocolate brown, but more horizontal banding. Can obtain more detailed and specific measurements of other needed dimensions if needed. Mainly I'm looking for a confirmation of Tyrannosaurid Indet distinguished from other theropods in the area at the time, as I have little experience positively IDing smaller tyrannosaurid material. I've actively worked on distinguishing Carcharodontosaur teeth from Rugops in the field in Morocco, but this is out of my field. All help is greatly appreciated! Will post more pictures in comments

Just looking for a little help identifying a hell creek vertebra. The individual I purchased it from said it was likely a Tyrannosaur cervical vertebra (probably rex rather than a nano vertebra due to its size). Based on its shape and the fact it's very light, I'm fairly confident their identification is correct. Any help would be much appreciated

Hi! I´m not very familiar with Russian dinosaur teeth, But I saw this tooth for sale and its labeled as Kileskus from Itat formation Russia. Is it possible that it is the correct id or could it be something else? The photos isnt very good though

Hello fossil enthusiasts! To identify this fossil, I'd love some help. My uncle had it, and now that he is passed, it was sent to me. He did not leave much information on it, and now we are all curious. He had a note with it that said "W. US LATE CRETACEOUS, DROM / TYRAN". I did a lot of research. It does look like the tooth belonged to one of those animals, but I am having difficulty figuring out which one. The lack of formation does not help. Could anyone here be able to weigh in on whether it came from a dromaeosaur or tyrannosaur? Or maybe some other dinosaur? His and my guess could be way off. I've read a lot of @Troodon posts so I could figure it out (without success), and would love for him or her to weigh in. Of course, all are welcome. Thank you!

Possible Tyrannosaur foot phalange with some repair
msantix posted a topic in Is It Real? How to Recognize Fossil Fabrications
I was originally going to ask about the id of this bone, but i figured it is much more important to ask about any possible restorations done that aren't in the description. This is a 24cm toe phalange from an undescribed Tyrannosaur (from the Ajuga Formation). The seller has stated that the bone was found in many pieces that were put back together (it is slightly compressed) and had some crack fills (and a tiny bit of stain), but nothing else. May i ask for opinions, my main concern is whether it could be a composite but i am mostly unaware of the type of preservation found in this formation. Thanks. -
From the album: Judith River fm. Fossil Finds
Here we have the tooth tip from a Tyrannosaurid I found at a microsite in Northern MT. Teeth, especially fragmentary ones like these are nearly impossible to identify accurately as the differences between those of Gorgosaurus and Daspletosaurus (the two species of tyrannosaur from the JRF) are difficult to distinguish.-

For context, I have received these photos from the shop that I have done business with previously. I want to ensure that these are rex teeth and not another genus. I acknowledge that these pictures do not show the base of the teeth which seems to be the tell tale differentiation, in addition to measurements of scale and so on. Therefore, I just would like to see the opinions of those on the forum with the pictures provided, I wish I was able to take more appropriate photos of the specimens. Tooth #1 strikes me as a likely rex candidate simply because of the robustness, #2 I'm not so sure. Not an expert on theropod teeth by any means. Thank you all! (The 98 million year old age is a typo, they have a more expensive tooth with the appropriate age of 68 million years)

Okay, so I have a couple of fossils in my collection, in which I'd like some more opinions on. First, I bought this un-identified dinosaur chevron bone. It is from the Kem Kem beds, Morocco.

Organizing my collection has been the tedious, but also a really fun process. I’ll probably continually posting here for assistance. When I’m feeling a little more confident about my ID’s, I’ll post it in the members collection section to share. I still have some fossils to prep, piece together, display, label, etc. and really fortunate that I have all of you helping constantly; it really speeds up the process. In another year’s time, I’ll be much more educated/ well rounded Some of my fossils are rookie purchases, so I’m just trying to make the best of it. The issue is , I think they’re pretty cool, but not sure if they are worth displaying given that they are bone fragments. I was thinking maybe in a riker...also the issue of labeling...Below are three separate purchases. Group 1: The seller sold these in fragments. Several of these pieces I glued back together neatly with Paleo bond. The seller must’ve used some kind of thick glue originally because there are some marks, but it’s no big deal... anyway these were advertised as Albertosaurus bones... when I asked the seller why he labeled it as such, he said because it’s very probable? I asked him for a coa, and when I received it, it only said Tyannosaur bones... so I’m going to leave it at that...because it’s indeterminable. Even back then I knew Coa’s were pointless, but I always like asking for one, because I feel like it could possibly put a little pressure on the seller to be a somewhat more honest like it did in this case...however in most cases sellers don’t care: Tyrannosaur bone fragments: Judith River Formation, Northern Montana The other small miscellaneous pieces I don’t think can be glued back...no fit or match, just associated bones...What would you label the fossil as, and are they worth displaying?
