Carcharodontosaurids were enormous bipedal carnivores with grasping hands and clawed digits. The recently discovered Giganotosaurus is considered as the largest known terrestrial carnivores. Various estimates find that it measured somewhere between 12.2 and 13 m (40 and 43 ft) in length, and between 6.5 and 13.3 tons in weight. Skull of the Giganotosaurus measures at ~1.95 m (6 ft 5 in) long.- Giganotosaurus by Wikipedia.- Carnosauria by Wikipedia
