Who is stronger than a T-rex
Known as Spinosaurus, the colossal predator sported a massive finlike sail on its back and a 3-foot-long (0.9 meters) jaw full of jagged teeth. Bigger than both T. rex and Giganotosaurus, it lived in the swamps and rivers of North Africa during the Cretaceous Period, about 112 million to 97 million years ago.
Why is Spinosaurus the deadliest dinosaur?
As long as a school bus and as heavy as an elephant, the Spinosaurus was the largest predatory dinosaur to have existed even bigger than Tyrannosaurus rex. This was a big deal because no other dinosaur has been proven to have been able to swim.
What is the fastest dinosaur in the world?
The fastest dinosaurs were probably the ostrich mimic ornithomimids, toothless meat-eaters with long limbs like ostriches. They ran at least 25 miles per hour from our estimates based on footprints in mud. But that's just a guess and you don't run your fastest in mud.
Which dinosaur is the most scariest?
Spinosaurus are most likely to be the most biggest and most fierce dinosaur of all time. If a Spinosaurus and a Majungasaurus fight each other, Spinosaurus will win, but Majungasaurus are most likely to defeat a T.rex.
