From the album: Hell Creek / Lance Formations
Not the prettiest tooth, but I very much enjoy fossils like this that demonstrate behavior and tell a story. T. rex and other Tyrannosaurs were unusual among theropods in that they consumed the entire carcass of an animal - bones and all. Most theropod dinosaurs have ziphodont teeth, thin and knife-like, good for cutting muscle from bone. The thick and robust teeth of adult Tyrannosaurs, coupled with their incredible bite force, allowed them to shatter and pulverize bone - even those of the large, formidable herbivores they hunted. Despite the robustness of their teeth, Tyrannosaur-

A Tyrannosaur tooth from Eastern Montana. Given the basal "pinching," this would be Nanotyrannus lancensis if it's valid (otherwise it's T. rex). Interesting to compare it to my other small Tyrannosaur teeth. The tip was probably broken after fossilization, but the gouges on the labial face may be inflicted while the tooth was in use. Note that the enamel is well-preserved with sharply resolved texture and is still clear.-

Tyrannosauridae (Cf. Tyrannosaurus rex) Hell Creek Fm., Wibaux Co., MT, USA This minute tooth is indeed Tyrannosaur: the mc/dc serration densities are virtually identical, and the denticle shape is not like those of Dromaeosaurids. It also has a slight pathology near the tip.-

Hi y'all, got this small theropod in the mail; I bought it suspecting it was Tyrannosaurid. Upon in-hand inspection, I believe that suspicion is confirmed. It bears close resemblance to one of my larger juvenile T. rex maxillary teeth. It also appears to have a slight pathology near the apex - a slight bend. @Troodon Tyrannosauridae Hell Creek Fm., Wibaux Co., MT, USA CH: 9 mm Mesial serration density: ~ 5.3 / mm Distal serration density: ~ 5 / mm Serration densities: Serrations:

Tyrannosauridae Hell Creek Fm., Powder River Co., MT, USA ~ 3.6 / mm Notice that the enamel is still clear, with the dentine visible underneath. If Nanotyrannus is valid, then this is Nanotyrannus.-

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?
