The most dangerous dinosaur is Spinosaurus.
What was the most dangerous dinosaur in the pre-historic world?
Allosaurus. It was forty feet long, had a massive yet narrow jaw, very long arms with huge claws, and hunted in packs of three to four. But as a family, the raptors where definitely the deadliest group of animals in the world.
It was the T-rex the dino king
I think its the t rex because its jaws is more bigger(more muscles in the jaws) than the spinosaurus whose jaws is thin.Even though the spinosaurus is bigger .the bigger it is the better tit fall.
Tyrannosaur
