Megalosauroidea is a group of carnivorous theropod dinosaurs. They lived from the Middle Jurassic to the Late Cretaceous period. Members of the group include Spinosaurus, Megalosaurus, and Torvosaurus.

Classification

[change | change source]

The definition of the clade Megalosauroidea includes Megalosaurus bucklandii and all taxa that share a more recent common ancestor with it than they do with Allosaurus fragilis or the House Sparrow.[1]

Below is a cladogram showing the relationships between different members of Megalosauroidea. It is based on a study by Carrano, Benson & Sampson (2012).[2]
