The skull, measuring 59.6 cm (23.5 in) in length, was proportionally shorter and deeper than in any other large carnivorous dinosaur. [T] [U] The snout was moderately broad, not as tapering as seen in more basal theropods like Ceratosaurus, and the jaws were curved upwards. [25] A prominent pair of horns protruded obliquely above the eyes.
Ceratosaurus / ˌ s ɛr ə t oʊ ˈ s ɔːr ə s / (from Greek κέρας/κέρατος keras/keratos 'horn' and σαῦρος sauros 'lizard') was a carnivorous theropod dinosaur that lived in the Late Jurassic period (Kimmeridgian to Tithonian ages).
By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, juvenile armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. Some experts have suggested the dinosaur was primarily a scavenger.
Carnosauria is an extinct group of carnivorous theropod dinosaurs that lived during the Jurassic and Cretaceous periods.. While Carnosauria was historically considered largely synonymous with Allosauroidea, some recent studies have revived Carnosauria as clade including both Allosauroidea and Megalosauroidea (which is sometimes recovered as paraphyletic with respect to Allosauroidea), and thus ...
Tyrannosaur tooth marks are the most commonly preserved feeding traces of carnivorous dinosaurs. [8] They have been reported from ceratopsians, hadrosaurs and other tyrannosaurs. [8] Tyrannosaurid bones with tooth marks represent about 2% of known fossils with preserved tooth marks. [8]
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 study in question noted that cooperative hunting of prey much larger than an individual predator, as is commonly inferred for theropod dinosaurs, is rare among vertebrates in general, and modern diapsid carnivores (including lizards, crocodiles, and birds) rarely cooperate to hunt in such a way. Instead, they are typically territorial and ...
