What was the T. rex rival?

For a dinosaur so terrifyingly powerful as Tyrannosaurus, there was no greater rival than Triceratops. Each was the acme of their respective lineage–one a hypercarnivorous bone-crusher, the other an immense three-horned herbivore.

What is T. rex worst enemy?

the Spinosaurus
As long as a school bus and as heavy as an elephant, the Spinosaurus was the largest predatory (animal-eating) dinosaur to have existed — even bigger than Tyrannosaurus rex. But its size isn’t the most important thing about the Spinosaurus.

Did T. rex have any natural predators?

There once was a place on Earth so overrun with giant, meat-eating predators that even a Tyrannosaurus rex would have been nervous. One predator there was even bigger than T. rex, and scientists now say it’s apparently the only aquatic dinosaur ever found. The swimming monster is called Spinosaurus aegyptiacus.

Did T. rex have any competition?

Meet the rex wrecker, a 3-ton competitor to tyrannosaurs who stoked a family rivalry over millions of years in western North America. …

Why did dinosaurs fight each other?

These brawls left nasty scars. Tyrannosaurs viciously bit each other on the face, though likely not with the intention to kill. Rather, these biting brawls were probably the result of different individuals’ competing for prizes, such as territory, mates or higher status, a new study finds.

Who would win in a fight between at rex and a Triceratops?

The plant-eating dinosaurs of the late Cretaceous period weren’t the smartest bunch. As a general rule, carnivores tend to have more advanced brains than herbivores, meaning Triceratops would have been far outclassed by T. Rex in the IQ department.

Are there any other dinosaurs similar to Tyrannosaurus rex?

Other tyrannosaurid fossils found in the same formations as Tyrannosaurus rex were originally classified as separate taxa, including Aublysodon and Albertosaurus megagracilis, the latter being named Dinotyrannus megagracilis in 1995. These fossils are now universally considered to belong to juvenile Tyrannosaurus rex.

What do we know about Tyrannosaurus rex biomechanics?

Specimens of Tyrannosaurus rex include some that are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens. The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics.

Did Tyrannosaurus rex live with a mouth closed?

Brachiosaurus and Diplodocus lived in a similar time span to Apatosaurus, and were already extinct by the time Tyrannosaurus rex appeared. Tyrannosaurus rex, however, coexisted with a large saltasaurid called Alamosaurus. Tyrannosaurs are now known not to roar, but to vocalize with their mouths closed.

What are the differences between Tyrannosaurus rex and Tarbosaurus bataar?

The feeding habits, physiology, and potential speed of Tyrannosaurus rex are a few subjects of debate. Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a second Tyrannosaurus species, while others maintain Tarbosaurus is a separate genus.
