Giganotosaurus Carolinii was a gigantic theropod dinosaur, larger than Tyrannosaurus or Carcharodontosaurus but not as long (though probably heavier) than Spinosaurus. Also new evidence that it hunted in packs could make it the deadliest dinosaur ever discovered.

SizeEdit

Giganotosaurus is significantly larger than Tyrannosaurus and Carcharodontosaurus, coming in at 15.0m and possibly larger, and weighing 15 tonnes. It is remarkable that even though the giants were far bigger than Tyrannosaurus, they were much faster. Palaeontologists reckon these behemoths could run at a dashing 50 km per hour.

Skull and BrainEdit

The Giganotosaurus's Skull was huge! The biggest of any theropod, in fact. At a staggering 1.9 meters long, it showed Giganotosaurus had a great sense of smell. Its brain was rather small, but not as small as a Carcharodontosaurus's.

BehaviorEdit

Titanosaur fossils belonging to Andesaurus, Argentinosaurus, and Limaysaurus have been recovered near the remains of Giganotosaurus, leading to speculation that these carnivores may have preyed on the giant herbivores, as Sauropods. Fossils of the related carcharodontosaurid Mapusaurus grouped closely together may indicate pack hunting, a behavior that could possibly extend to Giganotosaurus itself. Giganotosaurus had teeth that where up to 10 inches long and perfect for slicing through flesh. A very likely attack strategy is a "hit and run" where the Giganotosaurus runs in, takes a bite out of its prey, and then runs away before injury is inflicted. This way it could bleed out its sauropod prey instead of delivering a single powerful attack. This strategy has been scientifically proven in the fossil record by other dinosaurs, so we can assume that under similar circumstances, Giganotosaurus would do the same.
