Tyrannoraptora is a clade defined as "all descendants of the last common ancestor of Tyrannosaurus rex and Passer domesticus (the house sparrow)".[2] The clade was named in 1999 by the AmericanpaleontologistPaul Sereno, though in his original concept had Tyrannosauroidea being the sister taxon to Pennaraptora.[3] Phylogenetic analyses have since, however, found the group also encompasses Compsognathidae, Ornithomimosauria, Alvarezsauroidea, and Therizinosauria.[4][5][6] Thus tyrannoraptorans are divided into tyrannosauroids and maniraptoromorphs.
