Classification

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.

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