They conceded that comparison with Tyrannosaurus was difficult due to the disarticulated state of the cranial bones of Giganotosaurus, but noted that at 1.43 m (4.7 ft), the femur of Giganotosaurus was 5 cm (2 in) longer than that of "Sue", the largest known Tyrannosaurus specimen, and that the bones of Giganotosaurus appeared to be more robust ...
Since its discovery, however, a number of other giant carnivorous dinosaurs have been described, including Spinosaurus, Carcharodontosaurus, and Giganotosaurus. [34] These large theropod dinosaurs are estimated to rival or even exceeded Tyrannosaurus rex in size, though more recent studies and reconstructions show that Tyrannosaurus , although ...
Tyrannosaurus (/ t ɪ ˌ r æ n ə ˈ s ɔː r ə s, t aɪ-/) [a] is a genus of large theropod dinosaur.The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
T. rex has been the single species of the genus Tyrannosaurus recognized since the dinosaur was first described in 1905. T. rex still reigns as the king of dinosaurs, according to scientists who ...
The largest species was Tyrannosaurus rex, the most massive known terrestrial predator, which measured over 13 metres (43 ft) in length [2] and according to most modern estimates up to 8.87 metric tons (9.78 short tons) in weight. [3] [4] Tyrannosaurids were bipedal carnivores with massive skulls filled with large teeth. Despite their large ...
His findings, published in 2019, yielded that Scotty is the largest (in weight and length), having out-measured the previous largest known Tyrannosaurus rex: Sue of the Chicago Field Museum (FMNH 2081). [13] After prolonged study of the growth patterns in the bones, "Scotty" was also declared as one of the oldest known T. rex fossils at 30 ...
A proximal caudal has a very tall neural spine (about twice the height of its centrum, judging by the figure). The base of the orbital fenestra is a notch of nearly 90 degrees into the body of the jugal, which contrasts with the rounded base restored for Giganotosaurus and agrees with Carcharodontosaurus favorably.
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 ...
