Identification Tyrannosaur teeth have similarly-sized serrations on each edge, and the serrations are chisel-shaped. This is a classic "Nano-morph" tooth being compressed and blade-like (which is the primitive condition of Tyrannosaurs). Notes This tooth has excellent preservation, with serrations crossing the tip, and clear enamel. There is a minor wear facet near the tip on the lingual side, indicating this is from the left maxilla.

Tyrannosaurus rex Hell Creek Fm., Wibaux Co., MT, USA This is a juvenile Tyrannosaurid tooth. The serration densities are similar on each carina, the serrations are chisel-shaped and robust, the tooth is not recurved, and the mesial carina is straight. It closely resembles my larger T. rex maxillary tooth in cross section. -

This tooth is Tyrannosauridae tooth from china! I think it's Qianzhousaurus or bigger tyrannosaurid(Tarbosaurus or Zhuchengtyrannus). Size 3.1 inches. Very rare and big size. Discovered area : Nanxiong Formation, Jiangxi Province, China

From the album: Judith River fm. Fossil Finds
Probably my best find from that trip, this is so far the largest self found theropod tooth in my collection. It either belongs to Gorgosaurus or Daspletosaurus, though it is difficult to determine. Tyrannosauridae indet. (Either Gorgosaurus, Daspletosaurus or another taxon). Judith River fm.-

I've gotten a tooth and need help to identify it. He should comes from Wyoming (Hell Creek Formation) and is about 4,3cm (1.7 inches) tall. A geologist said, he might have come from a Carcharodontosaurus, but he does not come from North America. This is also the brown-black color. Carcharodontosaurus is native to Africa and would rather have sand color. However, I'm not a paleontologist^^. The Nanotyrannosaurus could it also be, if the origin is right. Of course, I also hope that it is not a fake, because on the inside, is a purple spot to see and I've never seen that in a fossil. By weight, it comes in any case to an original. It would be great if you could help me. (By the way, the Seller said it is a animal in family of the Tyrannosauridae)

Hey everyone There's this new bit of research from PeerJ, describing the partial remains of a new tyrannosaurid, Dynamoterror dynastes (pretty cool name, huh? ). The remains were from the Menefee Formation (Upper Cretaceous) of New Mexico, and are a valuable addition to our knowledge of North American tyrannosaurids. Partial cranial material of D. dynastes. McDonald et al. (2018). A new tyrannosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Menefee Formation of New Mexico. Abstract: The giant tyrannosaurids were the apex predators of western North America and Asia during the close of the Cretaceous Period. Although many tyrannosaurid species are known from numerous skeletons representing multiple growth stages, the early evolution of Tyrannosauridae remains poorly known, with the well-known species temporally restricted to the middle Campanian-latest Maastrichtian (∼77–66 Ma). The recent discovery of a new tyrannosaurid, Lythronax argestes, from the Wahweap Formation of Utah provided new data on early Campanian (∼80 Ma) tyrannosaurids. Nevertheless, the early evolution of Tyrannosauridae is still largely unsampled. We report a new tyrannosaurid represented by an associated skeleton from the lower Campanian Allison Member of the Menefee Formation of New Mexico. Despite fragmentation of much of the axial and appendicular skeleton prior to discovery, the frontals, a metacarpal, and two pedal phalanges are well-preserved. The frontals exhibit an unambiguous autapomorphy and a second potential autapomorphy that distinguish this specimen from all other tyrannosaurids. Therefore, the specimen is made the holotype of the new genus and species Dynamoterror dynastes. A phylogenetic analysis places Dynamoterror dynastes in the tyrannosaurid subclade Tyrannosaurinae. Laser-scanning the frontals and creation of a composite 3-D digital model allows the frontal region of the skull roof of Dynamoterror to be reconstructed.
