| Megalosauroids Temporal range: Middle Jurassic - Late Cretaceous, Possible Late Toarcian and Late Santonian records. Possible Campanian and Late Maastrichtian records,[1] but this is likely erroneous.

Megalosauroidea (meaning 'great/big lizard forms') is a superfamily (or clade) of tetanuran theropod dinosaurs that lived from the Middle Jurassic to the Late Cretaceous period. The group is defined as Megalosaurus bucklandii and all taxa sharing a more recent common ancestor with it than with Allosaurus fragilis or Passer domesticus.[2] Members of the group include Spinosaurus, Megalosaurus, and Torvosaurus. They are possibly paraphyletic in nature with respect to Allosauroidea.
