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 ...
The Allosaurus is now on display at the museum's R.B. Annis Mission Jurassic Paleo Lab, where a team is studying the fossil and clearing the matrix of rock around it. The legs are shown in a case ...
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.

It is notable as being the most fertile single source of dinosaur fossils in the world. The roster of dinosaurs from the Morrison is impressive. Among the theropods, Allosaurus, Saurophaganax, Torvosaurus, Ceratosaurus, Coelurus, Ornitholestes, Tanycolagreus, Stokesosaurus, and Marshosaurus are found in the Morrison.
There was a bevy of birds flying overhead of Allosaurus and Stegosaurus and Brontosaurus and the other iconic Jurassic dinosaurs," Brusatte added. (Reporting by Will Dunham in Washington, Editing ...
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 ...
It has been described as its own genus, [4] or as a species of Allosaurus: Allosaurus maximus. [7] A review of basal tetanurans in 2004 and Carrano et al.'s comprehensive 2012 analysis of Tetanurae accepted Saurophaganax as a distinct genus. [8] [9] Possible Saurophaganax material from New Mexico may clear up the status of the genus. [10]
The Ballad of Big Al, [a] marketed as Allosaurus [b] in North America, is a 2000 special episode of the nature documentary television series Walking with Dinosaurs. The Ballad of Big Al is set in the Late Jurassic, 145 million years ago, and follows a single Allosaurus specimen nicknamed "Big Al" whose life story has been reconstructed based on a well-preserved fossil of the same name.
