Appalachiosaurus ( ; “Appalachian lizard”) is a genus of tyrannosauroid theropod dinosaur from the Late Cretaceous period of what is now eastern North America. It was a basal member of the clade Eutyrannosauria, meaning it was rather close in relation to the true tyrannosaurids such as Tyrannosaurus. Like most theropods, it was a bipedal predator. Only a juvenile skeleton has been found, representing an animal approximately 6.5 m long and weighing 623 kg, which indicates an adult would have been significantly larger.
Fossils of Appalachiosaurus were found in central Alabama’s Demopolis Chalk Formation. This formation dates to the middle of the Campanian age of the Late Cretaceous, around 77 million years ago.
