We have authentic tyrannosaur teeth for sale from several different locations in the US. There are two tyrannosaurs described from the Hell Creek Formation Nanotyrannus and Tyrannosaurus rex (T-Rex). Many contemporary paleontologists believe that they are a single species, with Nanotyrannus representing a juvenile T-Rex but this is still a hotly debated topic. There are people that claim the Nanotyrannus are more laterally compress than T-Rex teeth but you would also see different tooth shapes depending on the placement of the tooth in the jaw. We also often have teeth for other older Tyrannosaurs such as Gorgosaurus and Daspletosaurus.
