Giganotosaurus is, I belive, Cenomanian, so it is indeed a little younger
Other giant non-tyrannosaurid theropods include the ?allosaurid
Chilantaisaurus, the allosaurid Saurophaganax, the megalosauroid Torvosaurus
(=Edmarka), Carcharadontosaurus, Bahariasaurus, Spinosaurus, and Deinocheirus.
Oops, forgot Therizinosaurus, too.
