Here's my young T-rex tooth. Species : Tyrannosaurus rex Formation : Hell Creek Place : Powder River County , Montana Age : 66 million years Tooth size: 1,05 inches

Hi everyone. I've been lurking around this site for some time looking over posts regarding t-tex teeth as I've been searching for an entry level specimen. I normally deal in high end mineral specimens, and generally keep away from fossils as it's a complex specialty. I recently purchased this tooth off an auction site and wanted to get an opinion or two about it's authenticity. From my past "lurking" it would appear this tooth matches the description and images I have seen previously posted. It's 1.6" and comes from "Hell Creek." Any educational feedback is greatly appreciated. Thank you in advance.

Hello everyone, This is my first time posting on here and I’m very new to fossil collecting. I’ve just spent [money] on a fossil and I feel like I might have made a mistake because I didn’t do my research fully. The T rex tooth is from a reputable online seller. I would really appreciate everyone’s opinion as I’m still learning? Also what are your thoughts about the enamels erosion and it’s possible link to digestion? Kind regards, Dylan Macnish

Is this a t-rex tooth? its from Lance creek formation but its doesn't have serrations and enamel just the tooth internal structure only

Its this a worn out t-rex tooth? its a 2.5 inches and its has no serrations and its from Hell creek formation

How big can the full rooted T-rex tooth size go up too?

Hey, just want to ask for some opinion whether if this tooth looks like a genuine T-Rex? While its not so fat in terms of shape like some of the clear T-Rex teeth out there, I have seen some pictures of certain teeth that seem to look a little thinner and more curvy that are supposedly T-Rex, so I can't be sure. It's a Hell Creek tooth BTW. If its not a rex what could this possibly be? An Albertosaurus seem like a likely candidate? Though from what I can see so far, it seems like a nice-looking tooth eventhough it apparently have had some restoration work done to it. What do u guys think?

A while ago I got myself what supposedly is a T-Rex tooth tip, though I have never been able to fully confirm whether if it was really a T-Rex or a Nanotyrannus. I have read about the T-Rex serration count (2 serration or less per mm, if I remember correctly) as a way to help identify a Rex tooth. Well, I have just managed to find a way to take a pic through a loupe with the tooth tip laying beside a tape measure to get a close-up of its serration. The tooth tip does seem to fit the bill (2 serration / mm) though, I think its probably better to upload the pics and let others with more expertise than me handling these teeth to take a look and share their input & opinions as well, just to be sure in case I may miss something. Anyway here is what the tooth tip looks like: And here are the pics of the serration count zoomed up close: So, does the tooth tip looks to be a T-Rex from the look of it? Thx in advance guys

Many serious dinosaur collectors would consider a good T-Rex tooth as probably the Holy Grail item in their dream collection. I am one of those people who would love to own one of these teeth in a collection. However from my research, online Googling and Ebay-hounding I have seen a lot of T-Rex teeth being offered online some for 4 digits figures and some in the 2 to 3 digits price range, though these cheaper ones are either small less than 2 inches or just tooth tip. While the expensive ones valued at the 1,000s of dollars with big fat long tooth tend to have clear T-Rex-ish features sold by dealers with mostly good reputation who seem to possess ID and preparation expertise, which I feel do not present much problem for the most part. Though, it's the smaller ones sold in the range of 100s of dollars that seem to present much more of a gambling when purchasing since I can see any dealers can simply put "T-Rex" tag on their supposedly "NanoTyrannus" specimen (which I believe isn't technically or scientifically wrong at this time due to the still disputing in the scientific community - correct me if I am wrong, though) and up the price or make the deal seem like a steal since for the same size an identified NanoTyrannus specimen would command much less price than a T-Rex one. To make the matter even more complicated, it seems really hard to differentiate the Nanotyrannus tooth from a T-Rex tooth with perhaps the exception of getting a microscope to count the serrations/cm. but I think that's not always realistically possible due to the impossibility of access to the specimen if you are buying online or due to the fact that the serrations may not be preserved enough to be able to do this effectively. What I try to get around this issue to minimize possibility of getting burned with my limited experience and accessibility with these things would be to buy small T-Rex tooth and set acceptable budget in the range that wouldn't exceed the Nanotyrannus tooth specimen too much. Meaning if I pay for a T-Rex tooth at a close-to-Nanotyrrannus price range, then if worse comes to worst and what I got isn't a "real T-Rex" tooth then I still got myself a fair priced NanoTyrannus tooth anyway. Anyone else with expertise in handling, buying or selling these things could add more tips or techniques when purchasing these things would be greatly appreciated I think it could benefit many new collectors looking to acquire dino-teeth specimen. Thxs!!
