Could Tyrannosaurus Coexist With Late Jurassic-Early Late Cretaceous Carnivores?

If Tyrannosaurus rex had existed a few million years earlier in the supercontinent of Africa and South America it would have encountered Spinosaurus, Carcharodontosaurus, Giganotosaurus and Ekrixinatosaurus among many other super predators.
So my question is "Could they have coexisted?".
I think they could. Carcharodontosaurs would play the role of sauropod slayers while Rex would eat hadrosaurs and other medium to large sized prey. Spinosaurus and the like would eat the giant fish, crocodiles and coastal dinosaurs and abelisaurs would eat primarily carrion and small animals with the exception of Ekrixinatosaurus, which would have been the only possible full time competitor of Rex. It could possibly coexist by eating small-medium sized sauropods like Saltasaurus or other prey assuming Rex favored ceratopsians and ankylosaurs over most things. They would all be sure to have clashed at some point but I think most of them could have peacefully coexisted 90% or more of the time.
If we factor in Jurassic dinosaurs like Saurophaganax, Epanterias, Torvosaurus, Edmarka, Das Monster von Minden and other unnamed allosaurs and megalosaurs, things could get tougher.
The allosaurs would either get along with or compete heavily with the carcharodontosaurs.
Megalosaurs would compete with several predator groups. They had the most mechanically efficient bites ever to exist in dinosaurs that were super powerful, likely matching tyrannosaurs. They also had the speed, size and arms to hunt a super wide variety of prey.
They could hunt anything from stegosaurs to hadrosaurs to ceratopsians to ankylosaurs to sauropods, something that would put them in near constant competition with every other predator, possibly excluding spinosaurs and most abelisaurs. Jurassic carnivores would kind of throw a wrench into the harmony cretaceous carnivores could exist in.
What do you think?
