Allosaurus was a large bipedal predator for its time. Its skull was light, robust, and equipped with dozens of sharp, serrated teeth. It averaged 8.5 meters (28 ft) in length for A. fragilis, with the largest specimens estimated as being 9.7 meters (32 ft) long. Relative to the large and powerful legs, its three-fingered hands were small and ...
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 ...
deltopectoral crest The deltopectoral crest is a forward directed bony flange on the upper part of the humerus. An especially long and prominent deltopectoral crest is a dinosaurian synapomorphy, i.e., a feature differentiating the group from other groups. In dinosaurs, the crest measures 30–40% of the length of the humerus.
In 2024, re-examinations of the specimens attributed to Saurophaganax suggested that it is a chimera of multiple dinosaur genera, since some specimens most likely belong to a diplodocid sauropod, while the other referred allosaurid specimens belong to a novel species of Allosaurus, named as Allosaurus anax.

Diplodocus is commonly found at the same sites as Apatosaurus, Allosaurus, Camarasaurus, and Stegosaurus. [111] Allosaurus accounted for 70 to 75% of theropod specimens and was at the top trophic level of the Morrison food web. [112]
The discovery of a back crest incorporating only two high vertebrae in Concavenator, in 2010 provided corroboration that the short anterior Altispinax spine may be complete. [20] Olshevsky originally assigned Altispinax to the Eustreptospondylidae. In 2003 Naish considered it a member of the Allosauroidea. [17]

Theropods such as Carcharodontosaurus, Allosaurus, and Acrocanthosaurus have enlarged lacrimal crests, whose purpose is unknown. Paleontologist Daniel Chure hypothesized that these crests were used for "head-butting" between individuals, but how durable they are has not been studied. [79]
