Giganotosaurus (/ ˌ ɡ ɪ ɡ ə ˌ n oʊ t ə ˈ s ɔː r ə s / GIG-ə-NOH-tə-SOR-əs [2]) is a genus of large theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago.
Carcharodontosaurids include some of the largest land predators ever known: Giganotosaurus, Mapusaurus, Carcharodontosaurus, and Tyrannotitan all rivaled Tyrannosaurus in size. Estimates give a maximum weight of 8–10 metric tons (8.8–11.0 short tons) for the largest carcharodontosaurids, while the smallest carcharodontosaurids were ...
With a length of around 2 m (6 ft 7 in) it was one of the biggest predators of Mallorca during the Early Pliocene. [278] The largest known blind snake is Boipeba tayasuensis with estimated total length of 1.1 m (3 ft 7 in). [279] The largest known land lizard is probably Megalania (Varanus priscus) at 7 m (23 ft) in length. [280]
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
Its anatomy indicated that it was an active predator that was likely warm-blooded, in marked contrast to the then-prevailing image of dinosaurs. [59] Concurrently, Robert T. Bakker published a series of studies that likewise argued for active lifestyles in dinosaurs based on anatomical and ecological evidence (see § Physiology ), [ 62 ] [ 63 ...
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.
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).
