The Allosauridae are a taxon of the Carnosauria and thus belong to the theropods (theropoda), the carnivorous dinosaurs. The allosaurids are larger and slimmer (thus also more agile) than the Megalosauridae . The tail accounted for more than half of the length. The short, heavy head with the saber-like teeth in the jaw sat on a strong neck that belonged to a relatively narrow body. The animals were all between 4.3 and 11 meters in length and weighed between 300 kg and 7 tons. They lived in the late Upper Jurassic .
The only well-known representative is Allosaurus , the largest being Saurophaganax maximus . The latter is only known on the basis of fewer bones, but is assigned by some scientists to Allosaurus ( A. maximus ). In addition, an unnamed fore limb from the Valanginium of France is assigned to the allosaurids.
