Spinosaurus is the longest known terrestrial carnivore; other large carnivores comparable to Spinosaurus include theropods such as Tyrannosaurus, Giganotosaurus and the coeval Carcharodontosaurus. The most recent study suggests that previous body size estimates are overestimated, and that S. aegyptiacus reached 14 m (46 ft) in length and 7.4 t ...

The authors also proposed Spinosaurus maroccanus as a junior synonym of Sigilmassasaurus, and rejected the proposal of a Spinosaurus aegyptiacus neotype. [4] A study by British paleontologist Thomas Arden and colleagues in 2018 concluded that Sigilmassasaurus was a valid genus and formed a tribe with Spinosaurus termed Spinosaurini.
