Arkansaurus measured about 4.6 metres (15 ft) long and weighed about 380.5 kilograms (839 lb). [8] [9] Examination of the holotype consisting of a nearly complete right foot suggests that Arkansaurus was similar to most ornithomimosaurians of the Early Cretaceous, with the strong curvature of the foot claws being the only exception: most ornithomimosaurians had flat claws.

Size comparison of seven carcharodontosaurids (Acrocanthosaurus in light brown) Acrocanthosaurus was among the largest theropods known to exist, with an estimated skull length of 1.23–1.29 m (4.0–4.2 ft) and body length of 11–11.5 m (36–38 ft) based on the largest known specimen (NCSM 14345).
Size comparison. Veterupristisaurus was a large bipedal animal.The length of the holotype vertebra is about 123 mm (4.8 in). Veterupristisaurus has been estimated to have been about 8 m (26 ft) in length and to have weighed 1.65 t (1.82 short tons; 1.65 t), [3] based on the more complete and closely related Acrocanthosaurus.
Abelisauridae (meaning "Abel's lizards") is a family (or clade) of ceratosaurian theropod dinosaurs.Abelisaurids thrived during the Cretaceous period, on the ancient southern supercontinent of Gondwana, and today their fossil remains are found on the modern continents of Africa and South America, as well as on the Indian subcontinent and the island of Madagascar.
Size comparison with an average human male Life restoration Archaeornithomimus was a medium sized ornithomimosaur, reaching 3.4 m (11 ft) long and weighing over 71.5 kilograms (158 lb). [ 18 ] [ 19 ] Solid evidence coming from other ornithomimosaurian relatives suggest that Archaeornithomimus was a feathered animal, with very ratite -like ...
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 comparison of Albertosaurus with Gorgosaurus and a human Albertosaurus was smaller than some other tyrannosaurids, such as Tarbosaurus and Tyrannosaurus . Typical adults of Albertosaurus and Gorgosaurus measured up to 8 to 9 m (26 to 30 ft) long, [ 4 ] [ 5 ] while rare individuals of Albertosaurus could grow to over 10 m (33 ft) in length ...
Size comparison. Sinraptor dongi skull specimen IVPP 10600 exhibits "a variety of gently curving tooth drags or gouges, shallow, circular punctures and one fully penetrating lesion." One rib was broken and healed via telescoping of its capitular shaft. [10]
