描述Megalosaurus 5.svg | English: Skeletal diagram of the large Jurassic theropod Megalosaurus bucklandii. A large amount of material has been assigned to Megalosaurus, but much of it pertains to other genera. The remains that do pertain to Megalosaurus bucklandii are often isolated and don't all belong to animals of the same size, making reconstruction difficult. While all illustrated and/or photographed specimens have been illustrated here, there are some other known specimens. However, these generally come from an area similar to that of better-described elements, and have been excluded due to ambiguity. The primary basis for the unknown material was Torvosaurus tanneri, a close relative of Megalosaurus, although T. gurneyi and Wiehenvenator albati were also used in some regions, as well as the less similar Afrovenator and Dubreuillosaurus. Afrovenator, as it is one of the few large megalosaurids to preserve a reasonably complete specimen, was used to scale the limb elements. The total length here is about 8 m (26 ft) long, although due to the uncertainty of the proportions, this estimate should be treated as tentative. Key - Known in the hypodigm (including the lectotype partial dentary)
- Unknown in the hypodigm but known in other specimens
- Unknown, restored after related species
