Giganotosaurus was one of the largest known terrestrial carnivores, but the exact size has been hard to determine due to the incompleteness of the remains found so far. Estimates for the most complete specimen range from a length of 12 to 13 m (39 to 43 ft), a skull 1.53 to 1.80 m (5.0 to 5.9 ft) in length, and a weight of 4.2 to 13.8 t (4.6 to ...
The dentary (tooth-bearing lower jaw bone) was squared off at the front edge, as in Giganotosaurus, and shallow, while the rest of the jaw behind it became very deep. Acrocanthosaurus and Giganotosaurus shared a thick horizontal ridge on the outside surface of the surangular bone of the lower jaw, underneath the articulation with the skull. [6]
Tyrannotitan (/ t ɪ ˌ r æ n ə ˈ t aɪ t ə n /; lit. ' tyrant titan ') is a genus of large theropod dinosaur belonging to the carcharodontosaurid family. It is known from a single species, T. chubutensis, which lived during the Albian stage of the Early Cretaceous period in what is now Argentina.

Argentinosaurus (meaning "lizard from Argentina") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
Size of a few specimens compared to a human. Mapusaurus was a large theropod, but slightly smaller in size than its close relative Giganotosaurus, with the largest specimen measuring around 10.2–12.2 metres (33–40 ft) long and weighing up to 3–6 metric tons (3.3–6.6 short tons).
The ratio of transversal width to anterior centrum height was 1.3, making the vertebra much wider than the cervical vertebrae preserved in carcharodontosaurids like Giganotosaurus and Tyrannotitan but more similar to that of Allosaurus, a more basal theropod. The third cervical vertebra described was unfigured and poorly preserved, though was ...
