More than half a century later in 1905, Tyrannosaurus was named, and it remained the largest known theropod dinosaur for 90 years, though other large theropods were also known. The discussion of which theropod was the largest was revived in the 1990s by new discoveries in Africa and South America. [1]
Since its discovery, Spinosaurus has been a contender for the largest theropod dinosaur. [44] Both Friedrich von Huene in 1926 [ 45 ] and Donald F. Glut in 1982 listed it as among the most massive theropods in their surveys, at 15 m (49 ft) in length and upwards of 6 t (6.6 short tons) in weight. [ 46 ]
Argentinosaurus might have been preyed on by Mapusaurus, which is among the largest theropods known. Mapusaurus is known from at least seven individuals found together, [53] raising the possibility that this theropod hunted in packs to bring down large prey including Argentinosaurus. [52]: 206–207
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 ...

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).
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 ...
