Publication History

Giganotosaurus may have been the largest and most massive predatory dinosaur that ever lived. The biggest giganotosaur was a yard longer and a ton heavier than "Sue", the largest known Tyrannosaurus rex. Despite a resemblance to the more famous tyrannosaurs, anatomical features of Giganotosaurus show it was a member of the Allosaurus clan.
