Tyrannosaurus rex vs Giganotosaurus is the ultimate megatheropod rivalry. After Tyrannosaurus rex fought Giganotosaurus in Jurassic World, science explains the true victor of a hypothetical fight in Tyrannosaurus rex vs Giganotosaurus: Battle of Kings. Tyrannosaurus rex size is an important factor, and this video about Tyrannosaurus rex vs Giganotosaurus includes a Tyrannosaurus rex size comparison as well as an in-depth analysis of each animal’s ecology, agility, intelligence, and experience in fighting other megatheropods. New science, including new mass estimations and biomechanical studies, reveal each competitor’s unique evolutionary abilities in this fight to the death: Tyrannosaurus vs Giganotosaurus. This is an educational scientific-reporting take on the Tyrannosaurus rex vs Giganotosaurus battle.
