Name	Status	Authors	Age	Unit	Location	Notes
Albertosaurus^[6]	Valid taxon	Henry Fairfield Osborn	Late Cretaceous (Edmontonian)	Horseshoe Canyon Formation	(	An albertosaurine tyrannosaurid.
"Diceratops"^[7]	Preoccupied.	Lull vide: Hatcher	Late Cretaceous (Lancian)		Has been considered a member of Triceratops, but recent work has indicated it deserved its own genus after all. In 2008 it was renamed Diceratus because Diceratops was preoccupied by a hymenopteran insect Foerster, 1868.
"Dynamosaurus"	Junior synonym.	Henry Fairfield Osborn	Late Cretaceous (Lancian)	Lance Formation		Same as Tyrannosaurus, this name was rejected because Tyrannosaurus was mentioned earlier in the paper.
Stegopelta^[8]	Valid taxon	Williston	Middle Cretaceous (Cenomanian)	Frontier Formation		A nodosaurid.
Tyrannosaurus	Valid taxon	Henry Fairfield Osborn	Late Cretaceous (Lancian)	Lance Formation Hell Creek Formation Scollard Formation North Horn Formation McRae Formation Frenchman Formation Denver Formation Laramie Formation	(and)	Tyrannosaurus is the largest recognized tyrannosauroid and the most famous dinosaur of all time.
