Identification: Originally listed as a Dromaeosaurid tooth, I suspected it was from a Tryannosaurid. Upon receiving the tooth, I contacted a few paleontologists to get expert opinions. Their conclusion was that the tooth was likely from a baby/juvenile Tyrannosaur. Since the only Tyrannosaurs in the Hell Creek Formation are Tyrannosaurus rex and Nanotyrannus lancensis (or only T. rex if N. lancensis is a young T. rex), and considering the cross-section of the base of the tooth, this must be from a baby Tyrannosaurus rex. This tooth shares many qualities with adult teeth, a fact which the experts used to justify their identification. The large denticles (serrations) on both carinae (cutting edges) are similar in shape and size, there's virtually no recurvature, no twisting of the carinae, and it has an oval base. The overall shape of the tooth also suggests that it's from the posterior region of the mouth. Among the attached photos are juxtapositions with a high-quality cast replica of an adult T. rex (Stan) posterior tooth, and a juvenile N. lancensis tooth (also from the Hell Creek Formation). Other: Mesial Serration Density: ~ 5.5 - 6 serrations / mm Distal Serration Density: ~ 5 - 5.5 serrations / mm Note: Serration density alone is not an identifying feature of Tyrannosaur teeth this small. Identifiers: The people that support this identification are: @Troodon (experienced and knowledgable collector on TFF); Dr. Philip J. Currie (noted paleontologist, museum curator, and professor specializing in Tyrannosaurs); Dr. David DeMar Jr. (research associate in the Department of Paleobiology of the National Museum of Natural History, Smithsonian Institution); and Dr. Christophe Hendrickx (postdoctoral researcher specializing in the evolution of theropod dentitions).

Hello TFF, I was scanning through a really popular shopping website and for auction, 3 t rex teeth were for sale. They are not in the most perfect or beautiful condition but hopefully and at the moment, they are around my budget. I just wanted to make sure that they are actual t rex teeth not nanotyrannus as it can be sometimes confusing. Would really like to ask for your opinions. The photos may be a bit blurry and unfortunately, these are the only ones available. BTW, The largest tooth was found in two and had to be glued together. The rest were found as one piece. Thanks guys!

Hello TFF, I started looking for T rex teeth these past few months and came upon this juvenile T rex tooth. It has got no visible serrations based on the photo. I asked the seller if he could give me some clearer photos of the specimen. I hope this is really a rex tooth! Would like to ask your opinion if it looks like a t rex tooth or not. Thank you all in advance for sharing your opinion!
