Giganotosaurus is thought to have been one of the largest theropod dinosaurs, but the incompleteness of its remains have made it difficult to estimate its size reliably. It is therefore impossible to determine with certainty whether it was larger than Tyrannosaurus, for example, which has been considered the largest theropod historically ...
The Therrien and Henderson study has been criticized for the choice of theropods used for comparison (e.g., most of the theropods used to set the initial equations were tyrannosaurids and carnosaurs, which have a different build than spinosaurids), and for the assumption that the Spinosaurus skull could be as little as 1.5 m (4 ft 11 in) in length.
The largest extant theropod is the common ostrich, up to 2.74 metres (9 ft 0 in) tall and weighs between 63.5 and 145.15 kilograms (140.0 and 320.0 lb). [35] The smallest non-avialan theropod known from adult specimens may be Anchiornis huxleyi, at 110 grams (3.9 ounces) in weight and 34 centimetres (13 in) in length, [36] although later study ...
In the modern fauna, theropods are represented by over 11,000 species of birds, which are a group of maniraptoran theropods within the clade Avialae.. Theropoda (/ θ ɪəˈr ɒ p ə d ə /; [2] from ancient Greek θηρίο-ποδός [θηρίον, (therion) "wild beast"; πούς, ποδός (pous, podos) "foot"]), commonly known as theropods, is an extant dinosaur clade that is ...
Cryolophosaurus was a large, well-built theropod, one of the largest of its time. The holotype specimen is estimated to have reached 6–7 m (20–23 ft) long and weighed 350–465 kg (772–1,025 lb).
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 ...
The wrist had a version of the semilunate carpal [117] also found in more derived theropods like maniraptorans. Of the three fingers, the innermost (or thumb) was the largest, [30] and diverged from the others. [16]
Fossils from perhaps the largest dinosaur ever found were discovered in 2012 in the Neuquén Province of northwest Patagonia, Argentina. ... their theropod predators ...
