Deinodon (Latin for "terrible tooth") is a name assigned to tyrannosaurid teeth of the Late Cretaceous of Montana by paleontologist Joseph Leidy in 1856 [1]. These were the first tyrannosaurid remains to be described.
Although it is likely that these fossilized teeth belonged to the dinosaur later identified as Gorgosaurus libratus, it is virtually impossible to distinguish between different tyrannosaurid species based on tooth characteristics alone, so Deinodon is today considered a nomen dubium - a dubious scientific name of little use.
