The tyrannosaurid family was a group of large carnivorous dinosaurs from the Late Cretaceous that was the pinnacle of the Tyrannosauroidea, a group of coelurosaurian theropods that appeared in the Jurassic. Other earlier tyrannosauroid families included the Proceratosauridae and the Dryptosauridae. Tyrannosaurids are typically large- to giant-sized predators like the famous T. rex, and most have reduced forelimbs with only two visible fingers. The family is divided into the albertosaurine and tyrannosaurine subfamilies, but recently a tribe called Alioramini has been named. This group is either a cluster within the subfamily Tyrannosaurinae or a sister group to the entire family Tyrannosauridae.
Tyrannosaurids seem to be Fire Dinosaurs by default, regardless of size. This might be due to the stereotypical depictions in paleo media of Tyrannosaurus living near or wandering in a volcanic surrounding, or because fire symbolically represents raw power and tyrannosaurs appear as if they would rely on brute strength alone.
- Aublysodon mirandus (dubious, probably Daspletosaurus)
- Albertosaurus sarcophagus
- Alectrosaurus olseni (may only be tyrannosauroid)
- Alioramus/A. remotus/A. altai (may belong just outside of Tyrannosauridae)
- Appalachiosaurus montgomeriensis (may only by tyrannosauroid)
- Daspletosaurus/D. torosus/D. horneri
- Deinodon horridus (likely dubious, known only from teeth identical to Gorgosaurus and Daspletosaurus)
- Gorgosaurus libratus (may be species of Albertosaurus, controversial)
- Qianzhousaurus sinensis (may belong just outside of Tyrannosauridae)
- Raptorex kriegsteini (potentially dubious, known only from juvenile specimens of uncertain fossil age)
- Tarbosaurus bataar (may be Tyrannosaurus species, controversial)
